As from the name itself, the cold spray coating takes place at very low temperature as compare to other thermal spray coatings. In all other thermal spray coating process the partial melting of the coating powder particles takes place before deposition, but cold spray process takes place in solid state. In cold spray process, the bonding of coating power with substrate is not metallurgical as in other thermal spray processes. Due to supersonic speed and less temperature of spray particles, solid state, dense, and oxide free coatings are produced. Due to these characteristics, the cold spray coatings have been used to protect the materials against hot corrosion. In the present study, the cold spray process, cold spray fundaments, its types, and its applications for high temperatures are discussed in the light of presently available literature. In addition, the assessment of cold spray with the competitive technologies has been conferred with available literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cold%20spray%20coating" title="cold spray coating">cold spray coating</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20corrosion" title=" hot corrosion"> hot corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20spray%20coating" title=" thermal spray coating"> thermal spray coating</a>, <a href="https://publications.waset.org/abstracts/search?q=high-temperature%20materials" title=" high-temperature materials "> high-temperature materials </a> </p> <a href="https://publications.waset.org/abstracts/89039/cold-spray-coating-and-its-application-for-high-temperature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89039.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">243</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">379</span> Iontophoretic Drug Transport: An Non-Invasive Transdermal Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashish%20Jain">Ashish Jain</a>, <a href="https://publications.waset.org/abstracts/search?q=Shivam%20Tayal"> Shivam Tayal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There has been great interest in the field of Iontophoresis since few years due to its great applications in the field of controlled transdermal drug delivery system. It is an technique which is used to enhance the transdermal permeation of ionized high molecular weight molecules across the skin membrane especially Peptides & Proteins by the application of direct current of 1-4 mA for 20-40 minutes whereas chemical must be placed on electrodes with same charge. Iontophoresis enhanced the delivery of drug into the skin via pores like hair follicles, sweat gland ducts etc. rather than through stratum corneum. It has wide applications in the field of experimental, Therapeutic, Diagnostic, Dentistry etc. Medical science is using it to treat Hyperhidrosis (Excessive sweating) in hands and feet and to treat other ailments like hypertension, Migraine etc. Nowadays commercial transdermal iontophoretic patches are available in the market to treat different ailments. Researchers are keen to research in this field due to its vast applications and advantages. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=iontophoresis" title="iontophoresis">iontophoresis</a>, <a href="https://publications.waset.org/abstracts/search?q=novel%20drug%20delivery" title=" novel drug delivery"> novel drug delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=transdermal" title=" transdermal"> transdermal</a>, <a href="https://publications.waset.org/abstracts/search?q=permeation%20enhancer" title=" permeation enhancer"> permeation enhancer</a> </p> <a href="https://publications.waset.org/abstracts/78410/iontophoretic-drug-transport-an-non-invasive-transdermal-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78410.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">254</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">378</span> Transdermal Therapeutic System of Lercanıdipine Hydrochloride: Fabrication and in Vivo Evaluation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jiji%20Jose">Jiji Jose</a>, <a href="https://publications.waset.org/abstracts/search?q=R.%20Narayanacharyulu"> R.

Objective: To develop transdermal therapeutic systems for LD and to evaluate its in vivo performance in rabbits. Methodology: Transdermal patches of LD were formulated using the polymer blend of eudragit RL100 (ERL) and polyvinyl pyrolidone (PVP) by casting method Propylene glycol (PG) and tween 80 were used as plasticizer and permeation enhancer respectively. The pharmaco kinetic parameters of LD after the administration of transdermal patches was compared with that of oral administration. The study was carried out in a two way crossover design in male New Zealand albino rabbits. Results: The formulation with ERL: PVP ratio 1:4 with 15% w/w PG as plasticizer and 4% w/w tween 80 as permeation enhancer showed the best drug release results. The pharmacokinetic parameters such as Cmax, tmax, mean residence time (MRT) and area under the curve (AUC 0-∞) were significantly different following transdermal administration compared to oral administration. The terminal half life of transdermally administered LD was found to similar that of oral administration. A sustained drug release over a period of 24 hrs was observed after transdermal administration. Conclusion: The fabricated transdermal delivery system have the potential to provide controlled and extended drug release, better bio availability and thus, this may improve the patient compliance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transdermal%20therapeutic%20system" title="transdermal therapeutic system">transdermal therapeutic system</a>, <a href="https://publications.waset.org/abstracts/search?q=lercanidipine%20hydrochloride" title=" lercanidipine hydrochloride"> lercanidipine hydrochloride</a>, <a href="https://publications.waset.org/abstracts/search?q=eudragit" title=" eudragit"> eudragit</a>, <a href="https://publications.waset.org/abstracts/search?q=skinpermeation" title=" skinpermeation"> skinpermeation</a> </p> <a href="https://publications.waset.org/abstracts/10017/transdermal-therapeutic-system-of-lercanidipine-hydrochloride-fabrication-and-in-vivo-evaluation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10017.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">615</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">377</span> The Effect of Backing Layer on Adhesion Properties of Single Layer Ketoprofen Transdermal Drug Delivery System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Hamedanlou">Maryam Hamedanlou</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahla%20Hajializadeh"> Shahla Hajializadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The transdermal drug delivery system is one of the types of novel drug delivery system that the drug is absorbed into the skin.

The effect of spray height, type of nanofluids and concentration of nanofluids are numerically investigated. Five different nanofluids such as AgH2O, Al2O3, CuO, SiO2 and TiO2 with volume fraction range of 0.5% to 2.5% are used. The results revealed that the heat transfer performance decreases as spray height increases. It is found that TiO2 has the highest transfer coefficient among other nanofluids.

Dissolvable transdermal patches have emerged as a promising platform for delivering a variety of drugs due to their ease of use. The objective of this research was to create and characterize dissolvable transdermal patches using various compositions and ratios of hyaluronic acid and zinc oxide nanoparticles. A micromolding technique was utilized to fabricate the patches, which were subsequently characterized using scanning electron microscopy, atomic force microscopy, and tensile strength testing. In vitro drug release studies were conducted to evaluate the drug release kinetics of the patches. The study found that the mechanical strength and dissolution properties of the patches were influenced by the hyaluronic acid and zinc oxide nanoparticle ratios used in the fabrication process. Moreover, the patches demonstrated controlled delivery of model drugs through the skin, highlighting their potential for transdermal drug delivery applications. The results suggest that dissolvable transdermal patches can be tailored to meet specific requirements for drug delivery applications using different compositions and ratios of hyaluronic acid and zinc oxide nanoparticles. This development has the potential to improve treatment outcomes and patient compliance in various therapeutic areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transdermal%20drug%20delivery" title="transdermal drug delivery">transdermal drug delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization" title=" characterization"> characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=skin%20permeation" title=" skin permeation"> skin permeation</a>, <a href="https://publications.waset.org/abstracts/search?q=biodegradable%20materials" title=" biodegradable materials"> biodegradable materials</a> </p> <a href="https://publications.waset.org/abstracts/166832/fabrication-and-characterization-of-dissolvable-microneedle-patches-using-different-compositions-and-ratios-of-hyaluronic-acid-and-zinc-oxide-nanoparticles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166832.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">90</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">374</span> Effect of Span 60, Labrasol, and Cholesterol on Labisia pumila Loaded Niosomes Quality</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Binti%20Ya%E2%80%99akob">H.

At the optimum formulation, the niosome obtained significantly improved the quality of transdermal penetration of LP compared to free LP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Labisia%20pumila" title="Labisia pumila">Labisia pumila</a>, <a href="https://publications.waset.org/abstracts/search?q=niosomes" title=" niosomes"> niosomes</a>, <a href="https://publications.waset.org/abstracts/search?q=transdermal" title=" transdermal"> transdermal</a>, <a href="https://publications.waset.org/abstracts/search?q=quality" title=" quality"> quality</a> </p> <a href="https://publications.waset.org/abstracts/71190/effect-of-span-60-labrasol-and-cholesterol-on-labisia-pumila-loaded-niosomes-quality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71190.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">315</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">373</span> Quantitative Characterization of Single Orifice Hydraulic Flat Spray Nozzle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y.%20C.%20Khoo">Y.

The two techniques were high resolution flow visualization and Particle Image Velocimetry (PIV). A CCD camera with 29 million pixels was used to capture shadowgraph images to realize ligament formation and collapse as well as droplet interaction. Quantitative analysis was performed to give the sizing information of the droplets and ligaments. This camera was then applied with a PIV system to evaluate the overall velocity field of the spray, from nozzle exit to droplet discharge. PIV images were further post-processed to determine the inclusion angle of the spray. The results from those investigations provided significant quantitative understanding of the spray structure. Based on the quantitative results, detailed understanding of the spray behavior was achieved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spray" title="spray">spray</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20visualization" title=" flow visualization"> flow visualization</a>, <a href="https://publications.waset.org/abstracts/search?q=PIV" title=" PIV"> PIV</a>, <a href="https://publications.waset.org/abstracts/search?q=shadowgraph" title=" shadowgraph"> shadowgraph</a>, <a href="https://publications.waset.org/abstracts/search?q=quantitative%20sizing" title=" quantitative sizing"> quantitative sizing</a>, <a href="https://publications.waset.org/abstracts/search?q=velocity%20field" title=" velocity field"> velocity field</a> </p> <a href="https://publications.waset.org/abstracts/11794/quantitative-characterization-of-single-orifice-hydraulic-flat-spray-nozzle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11794.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">381</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">372</span> Sea-Spray Calculations Using the MESO-NH Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alix%20Limoges">Alix Limoges</a>, <a href="https://publications.waset.org/abstracts/search?q=William%20Bruch"> William Bruch</a>, <a href="https://publications.waset.org/abstracts/search?q=Christophe%20Yohia"> Christophe Yohia</a>, <a href="https://publications.waset.org/abstracts/search?q=Jacques%20Piazzola"> Jacques Piazzola</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A number of questions arise concerning the long-term impact of the contribution of marine aerosol fluxes generated at the air-sea interface on the occurrence of intense events (storms, floods, etc.) in the coastal environment. To this end, knowledge is needed on sea-spray emission rates and the atmospheric dynamics of the corresponding particles. Our aim is to implement the mesoscale model MESO-NH on the study area using an accurate sea-spray source function to estimate heat fluxes and impact on the precipitations. Based on an original and complete sea-spray source function, which covers a large size spectrum since taking into consideration the sea-spray produced by both bubble bursting and surface tearing process, we propose a comparison between model simulations and experimental data obtained during an oceanic scientific cruise on board the navy ship Atalante. The results show the relevance of the sea-spray flux calculations as well as their impact on the heat fluxes and AOD. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atmospheric%20models" title="atmospheric models">atmospheric models</a>, <a href="https://publications.waset.org/abstracts/search?q=sea-spray%20source" title=" sea-spray source"> sea-spray source</a>, <a href="https://publications.waset.org/abstracts/search?q=sea-spray%20dynamics" title=" sea-spray dynamics"> sea-spray dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=aerosols" title=" aerosols"> aerosols</a> </p> <a href="https://publications.waset.org/abstracts/148639/sea-spray-calculations-using-the-meso-nh-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148639.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">149</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">371</span> Iontophoretic Drug Transport of Some Anti-Diabetic Agents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashish%20Jain">Ashish Jain</a>, <a href="https://publications.waset.org/abstracts/search?q=Satish%20Nayak"> Satish Nayak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Transdermal iontophoretic drug delivery system is viable drug delivery platform technology and has a strong market worldwide. Transdermal drug delivery system is particularly desirable for therapeutic agents that need prolonged administration at controlled plasma level. This makes appropriateness to antihypertensive and anti-diabetic agents for their transdermal development. Controlled zero order absorption, easily termination of drug delivery and easy to administration also support for popularity of transdermal delivery. In this current research iontophoretic delivery of various anti diabetic agents like glipizide, glibenclamide and glimepiride were carried out. The experiments were carried out at different drug concentrations and different current densities using cathodal iontophoresis. Diffusion cell for iontophoretic permeation study was modified according to Glikfield Design. Pig skin was used for in vitro permeation study and for the in-vivo study New Zealand rabbits were used. At all concentration level iontophoresis showed enhanced permeation rate compared to passive controls. Iontophoretic transports of selected drugs were found to be increased with the current densities. Results showed that target permeation rate for selected drugs could be achieved with the aid of iontophoresis by increasing the area in an appreciable range. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transdermal" title="transdermal">transdermal</a>, <a href="https://publications.waset.org/abstracts/search?q=iontophoresis" title=" iontophoresis"> iontophoresis</a>, <a href="https://publications.waset.org/abstracts/search?q=pig%20skin" title=" pig skin"> pig skin</a>, <a href="https://publications.waset.org/abstracts/search?q=rabbits" title=" rabbits"> rabbits</a>, <a href="https://publications.waset.org/abstracts/search?q=glipizide" title=" glipizide"> glipizide</a>, <a href="https://publications.waset.org/abstracts/search?q=glibeclamide" title=" glibeclamide"> glibeclamide</a> </p> <a href="https://publications.waset.org/abstracts/45635/iontophoretic-drug-transport-of-some-anti-diabetic-agents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45635.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">384</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">370</span> Design, Development and Characterization of Pioglitazone Transdermal Drug Delivery System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dwarakanadha%20Reddy%20Peram">Dwarakanadha Reddy Peram</a>, <a href="https://publications.waset.org/abstracts/search?q=D.%20Swarnalatha"> D.

The diffusion studies were performed by using modified Franz diffusion cells. The result of dissolution studies shows that formulation, F3 (Olibanum with 50 mg) showed maximum release of 99.95 % in 12hrs, whereas F1 (Olibanum and EC backing membrane) showed minimum release of 93.65% in 12 hr.

It has been suggested by Williams–Landel–Ferry kinetics (WLF) that a higher particle temperature and lower glass-transition temperature would increase the crystallization rate of the particles during the spray-drying process. Freshly humidified air produced by a Buchi-B290 spray dryer as a humidifier attached to the main spray dryer decreased the particle glass-transition temperature (Tg), while allowing the particle temperature (Tp) to reach higher values by using an insulated drying chamber. Differential scanning calorimetry (DSC) and moisture sorption analysis were used to measure the degree of crystallinity for the spray-dried lactose powders. The results showed that higher Tp-Tg, as a result of applying humid air, improved the process yield from 21 ± 4 to 26 ± 2% and crystallinity of the particles by decreasing the latent heat of crystallization from 43 ± 1 to 30 ± 11 J/g and the sorption peak height from 7.3 ± 0.7% to 6 ± 0.7%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lactose" title="lactose">lactose</a>, <a href="https://publications.waset.org/abstracts/search?q=crystallization" title=" crystallization"> crystallization</a>, <a href="https://publications.waset.org/abstracts/search?q=spray%20drying" title=" spray drying"> spray drying</a>, <a href="https://publications.waset.org/abstracts/search?q=humid%20air" title=" humid air"> humid air</a> </p> <a href="https://publications.waset.org/abstracts/7244/effect-of-humidity-on-in-process-crystallization-of-lactose-during-spray-drying" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7244.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">425</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">368</span> A Randomised, Single-Dose, Two-Period, Cross-Over Phase I Pharmacokinetic Study to Compare TDS®-Diazepam with Rectal Diazepam in Healthy Adult Subjects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Faisal%20O.%20Al-Otaibi">Faisal O.

The aim of this study was to assess the ability of the TDS preparation to deliver diazepam systemically, and to characterize the pharmacokinetic profile of the drug in healthy adult subjects. We conducted a randomized, single-dose, two-period, crossover phase I (pharmacokinetic) comparative study in twelve healthy volunteers. All volunteers received both 10 mg TDS-diazepam topically to the upper chest and 10 mg of the rectal diazepam preparation (Diastat®, 10 mg diazepam gel), with a minimum washout of 14 days between dosing episodes. Both formulations were well tolerated in all volunteers. Following topical application of TDS-diazepam, the mean AUC0-72h was 1241 ng/mL.h and the Cmax 34 ng/mL. The values for rectal Diastat were 4109 ng/mL.h and 300 ng/mL respectively. This proof of concept study demonstrates that the TDS preparation successfully delivered diazepam systemically to adults. As expected, the concentration of diazepam following the TDS application was lower and not bioequivalent to rectal gel. Future development of this unique system is required. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transdermal%20delivery%20system" title="transdermal delivery system">transdermal delivery system</a>, <a href="https://publications.waset.org/abstracts/search?q=diazepam" title=" diazepam"> diazepam</a>, <a href="https://publications.waset.org/abstracts/search?q=seizure" title=" seizure"> seizure</a>, <a href="https://publications.waset.org/abstracts/search?q=bioequivalence" title=" bioequivalence"> bioequivalence</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmacokinetic" title=" pharmacokinetic"> pharmacokinetic</a> </p> <a href="https://publications.waset.org/abstracts/12728/a-randomised-single-dose-two-period-cross-over-phase-i-pharmacokinetic-study-to-compare-tds-diazepam-with-rectal-diazepam-in-healthy-adult-subjects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12728.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">425</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">367</span> Press Hardening of Tubes with Additional Interior Spray Cooling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20A.%20Behrens">B.

Traditionally, the quality of spray-dried milk powders has mainly been assessed using their physical properties, such as their moisture contents, while chemical changes occurring during the spray drying process have often been ignored. With growing concerns about food quality, it is necessary to establish a better understanding of heat-induced degradation due to the spray-drying process of skim milk. In this study, the extent of thermal degradation for skim milk in a pilot-scale spray dryer has been investigated using different inlet gas temperatures. The extent of heat-induced damage has been measured by the formation of advanced Maillard reaction products and the loss of soluble proteins at pH 4.6 as assessed by a fluorometric method. A significant increase in the extent of thermal degradation has been found when the inlet gas temperature increased from 170°C to 190°C, suggesting protein unfolding may play an important role in the kinetics of heat-induced degradation for milk in spray dryers. Colour changes of the spray-dried skim milk powders have also been analysed using a standard lighting box. Colourimetric analysis results were expressed in CIELAB colour space with the use of the E index (E) and the Chroma (C) for measuring the difference between colours and the intensity of the colours. A strong linear correlation between the colour intensity of the spray-dried skim milk powders and the formation of advanced Maillard reaction products has been observed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=colour%20formation" title="colour formation">colour formation</a>, <a href="https://publications.waset.org/abstracts/search?q=Maillard%20reactions" title=" Maillard reactions"> Maillard reactions</a>, <a href="https://publications.waset.org/abstracts/search?q=spray%20drying" title=" spray drying"> spray drying</a>, <a href="https://publications.waset.org/abstracts/search?q=skim%20milk%20powder" title=" skim milk powder"> skim milk powder</a> </p> <a href="https://publications.waset.org/abstracts/120841/colour-formation-and-maillard-reactions-in-spray-dried-milk-powders" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120841.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">183</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">364</span> Effect of Temperature and Feed Solution on Microencapsulation of Quercetin by Spray Drying Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Lekhavat">S.

The results showed that feed solution has total soluble solid and viscosity in range of 1.73-5.60 ºBrix and 2.58-8.15 cP, in that order. After spray drying, the moisture content and water activity value of powder are in range of 0.58-2.72 % and 0.18-0.31, respectively. Quercetin content in dried sample increased along with outlet drying temperature but decreased when total soluble solid increased. It was shown that particles are likely to shrivel when spray drying at high temperature. The suggested conditions for encapsulation of quercetin are feed solution with 0.0625 % (w/w) quercetin and spray drying at drying outlet temperature of 90°C. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drying%20temperature" title="drying temperature">drying temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20morphology" title=" particle morphology"> particle morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=spray%20drying" title=" spray drying"> spray drying</a>, <a href="https://publications.waset.org/abstracts/search?q=quercetin" title=" quercetin"> quercetin</a> </p> <a href="https://publications.waset.org/abstracts/53309/effect-of-temperature-and-feed-solution-on-microencapsulation-of-quercetin-by-spray-drying-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53309.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">260</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">363</span> Numerical Simulation and Analysis on Liquid Nitrogen Spray Heat Exchanger</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wenjing%20Ding">Wenjing Ding</a>, <a href="https://publications.waset.org/abstracts/search?q=Weiwei%20Shan"> Weiwei Shan</a>, <a href="https://publications.waset.org/abstracts/search?q=Zijuan"> Zijuan</a>, <a href="https://publications.waset.org/abstracts/search?q=Wang"> Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chao%20He"> Chao He</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Liquid spray heat exchanger is the critical equipment of temperature regulating system by gaseous nitrogen which realizes the environment temperature in the range of -180 ℃~+180 ℃.

It is characterized by the presence of frequent seizures occurring more than 24 hours apart. Carbamazepine (CBZ) is considered first-line treatment for epilepsy. However, reports have shown that CBZ oral formulations failed to achieve optimum systemic delivery, minimize side effects, and enhance patient compliance. Besides, the literature has signified the lack of therapeutically efficient CBZ transdermal formulation and the urge for its existence owing to its ease and convenient method of application and highlighted capability to attain higher bioavailability and more extended-release profiles compared to conventional oral CBZ tablets. This work aims to prepare CBZ microspheres (MS) that are embedded in a transdermal gel containing Vitamin B to be co-delivered. MS were prepared by emulsion-solvent diffusion method using Eudragit S as core forming polymer and hydroxypropyl methylcellulose (HPMC) polymer. The MS appeared to be spherical and porous in nature, offering a large surface area and high entrapment efficiency of CBZ. The transdermal gel was prepared by solvent-evaporation technique using HPMC that, offered high entrapment efficiency and Eudragit S that provided an extended-release profile. Polyethylene glycol, Span 80 and Pyridoxine were also added. Data indicated that combinations of CBZ with pyridoxine can reduce epileptic seizures without affecting motor coordination. Extended-release profiles were evident for this system. The patches were furthermore tested for thickness, moisture content, folding endurance, spreadability and viscosity measurements. This novel pharmaceutical formulation would be of great influence on seizure control, offering better therapeutic effects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=epilepsy" title="epilepsy">epilepsy</a>, <a href="https://publications.waset.org/abstracts/search?q=carbamazepine" title=" carbamazepine"> carbamazepine</a>, <a href="https://publications.waset.org/abstracts/search?q=pyridoxine" title=" pyridoxine"> pyridoxine</a>, <a href="https://publications.waset.org/abstracts/search?q=transdermal" title=" transdermal"> transdermal</a> </p> <a href="https://publications.waset.org/abstracts/182988/transdermal-medicated-layered-extended-release-patches-for-co-delivery-of-carbamazepine-and-pyridoxine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182988.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">59</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">361</span> The Physics of Cold Spray Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ionel%20Botef">Ionel Botef</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Studies show that, for qualitative coatings, the knowledge of cold spray technology must focus on a variety of interdisciplinary fields and a framework for problem solving.

The composite was developed through the unique spray forming route in the spray forming chamber by using N₂ gas at 7kg/cm² and the flight distance was 400 mm. Spray formed composite having a certain amount of porosity which was reduced by the deformations. The composite was subjected to the warm rolling (WR) at 250ºC up to 40% reduction. Spray forming composite shows the considerable microstructure refinement, equiaxed grains, distribution of silicon and graphite particles in the primary matrix of the composite. Graphite (Gr) was incorporated externally during the process that works as a solid lubricant. Porosity decreased after reduction and hardness increases. Pin on disc test has been performed to analyze the wear behavior which is the function of sliding distance for all percent reduction of the composite. 30% WR composite shows the better result of wear rate and coefficient of friction. The improved wear properties of the composite containing Gr are discussed in light of the microstructural features of spray formed the composite and the nature of the debris particles. Scanning electron microscope and optical microscope analysis of the present material supported the prediction of aforementioned changes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Al-6Si-1Mg-1Graphite" title="Al-6Si-1Mg-1Graphite">Al-6Si-1Mg-1Graphite</a>, <a href="https://publications.waset.org/abstracts/search?q=spray%20forming" title=" spray forming"> spray forming</a>, <a href="https://publications.waset.org/abstracts/search?q=warm%20rolling" title=" warm rolling"> warm rolling</a>, <a href="https://publications.waset.org/abstracts/search?q=wear" title=" wear"> wear</a> </p> <a href="https://publications.waset.org/abstracts/77455/tribological-behavior-of-warm-rolled-spray-formed-al-6si-1mg-1graphite-composite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77455.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">565</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">359</span> Technology of Thermal Spray Coating Machining</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jana%20Petr%C5%AF">Jana Petrů</a>, <a href="https://publications.waset.org/abstracts/search?q=Tom%C3%A1%C5%A1%20Zl%C3%A1mal"> Tomáš Zlámal</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20%C4%8Cep"> Robert Čep</a>, <a href="https://publications.waset.org/abstracts/search?q=Lenka%20%C4%8Cepov%C3%A1"> Lenka Čepová</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article is focused on the thermal spray coating machining issue.

Transdermal route may be selected as an alternative to enhance the bioavailability. Half-life of the drug is 6-7 hours suggesting the requirement of prolonged release of the drug. The present work of transdermal niosomal gel aims to extend release of the drug and increase the bioavailability. Ethanol injection method was used for the preparation of niosomes using span-60 and cholesterol at different molar ratios following central composite design. The prepared niosomes were characterized for size, zeta-potential, entrapment efficiency, drug content and in-vitro drug release. Optimized formulation was selected by statistically analyzing the results obtained using the software Stat-Ease Design Expert. The optimized formulation also showed high drug retention inside the vesicles over a period of three months at a temperature of 4 °C indicating stability. Niosomes separated as a pellet were dried and incorporated into the hydrogel prepared using chitosan a natural polymer as a gelling agent. The effect of various chemical permeation enhancers was also studied over the gel formulations. The prepared formulations were characterized for viscosity, pH, drug release using Franz diffusion cells, and skin irritation test as well as in-vivo pharmacological activities. Atenolol niosomal gel preparations showed the prolonged release of the drug and pronounced antihypertensive activity indicating the suitability of niosomal gel for topical and systemic delivery of atenolol. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atenolol" title="atenolol">atenolol</a>, <a href="https://publications.waset.org/abstracts/search?q=chitosan" title=" chitosan"> chitosan</a>, <a href="https://publications.waset.org/abstracts/search?q=niosomes" title=" niosomes"> niosomes</a>, <a href="https://publications.waset.org/abstracts/search?q=transdermal" title=" transdermal"> transdermal</a> </p> <a href="https://publications.waset.org/abstracts/59549/formulation-evaluation-and-statistical-optimization-of-transdermal-niosomal-gel-of-atenolol" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59549.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">294</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">357</span> The Effect of Water Droplets Size in Fire Fighting Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tassadit%20Tabouche">Tassadit Tabouche</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water sprays pattern, and water droplets size (different droplets diameter) are a key factors in the success of the suppression by water spray.

Amla is very high in vitamin C content. Spray drying of fruit juices represents another alternative way to improve the physicochemical stability and increase their shelf life. Samples of amla powder were produced using the spray drying method to investigate the effect of inlet temperatures and maltodextrin levels. The spray dryer model used was a laboratory scale dryer and samples were run at different temperatures and concentrations. The response surface methodology (RSM) was used to optimize the spray-drying process for the development of amla powder. The resultant powders were then analyzed for vitamin C, moisture, solubility and dispersibility. The spray dried amla powder contains higher amounts of vitamin C when compared to commercial fruit juice powders. SEM analysis revealed that lower maltodextrin levels and higher inlet air temperatures resulted in smaller but smoother particles. At lower temperature, vitamin C content is high as compared to higher temperature. Spray drying is an effective as well as an economic method which can be commercially used for making powder rather than by tray or solar drying as more fraction is retained with less cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amla%20powder" title="Amla powder">Amla powder</a>, <a href="https://publications.waset.org/abstracts/search?q=physiochemical%20properties" title=" physiochemical properties"> physiochemical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20surface%20methodology" title=" response surface methodology"> response surface methodology</a>, <a href="https://publications.waset.org/abstracts/search?q=spray%20drying" title=" spray drying"> spray drying</a> </p> <a href="https://publications.waset.org/abstracts/100795/preparation-of-amla-phyllanthus-emblica-powder-using-spray-drying-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100795.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">244</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">354</span> Effect of Drop Impact Behavior on Spray Retention</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hassina%20Hafida%20Boukhalfa">Hassina Hafida Boukhalfa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Massinon"> Mathieu Massinon</a>, <a href="https://publications.waset.org/abstracts/search?q=Fr%C3%A9deric%20Lebeau"> Fréderic Lebeau</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Belhamra"> Mohamed Belhamra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Drop behaviour during impact affects retention. The increase of adhesion is usually seen as the objective when applying crop protection products, while bouncing and shattering are seen as detrimental to spray retention. However, observation of drop impacts using high speed shadow graphy shows that fragmentation can occur in Wenzel wetting regime. In this case, a part of the drop sticks on the surface, what contributes to retention. Using simultaneous measurements of drop impacts with high speed imaging and of retention with fluorometry for 3 spray mixtures on excised barley leaves allowed us to observe that about 50% of the drops fragmented in Wenzel state remain on the leaf. Depending on spray mixture, these impact outcomes accounted for 25 to 50% of retention, the higher contribution being correlated with bigger VMD (Volume Median Diameter). This contribution is non-negligible and should be considered when a modelling of spray retention process is performed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drop%20impact" title="drop impact">drop impact</a>, <a href="https://publications.waset.org/abstracts/search?q=retention" title=" retention"> retention</a>, <a href="https://publications.waset.org/abstracts/search?q=fluorometry" title=" fluorometry"> fluorometry</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20speed%20imaging" title=" high speed imaging"> high speed imaging</a> </p> <a href="https://publications.waset.org/abstracts/47237/effect-of-drop-impact-behavior-on-spray-retention" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47237.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">381</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">353</span> Combined Effect of Vesicular System and Iontophoresis on Skin Permeation Enhancement of an Analgesic Drug </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jigar%20N.%20Shah">Jigar N.

The stratum corneum layer of the skin is working as the rate limiting step in transdermal transport and reduce drug permeation through skin. Many approaches have been used to enhance the penetration of drugs through this layer of the skin. The purpose of this study is to investigate the development and evaluation of a combined approach of drug carriers and iontophoresis as a vehicle to improve skin permeation of an analgesic drug. Iontophoresis is a non-invasive technique for transporting charged molecules into and through tissues by a mild electric field. It has been shown to effectively deliver a variety of drugs across the skin to the underlying tissue. In addition to the enhanced continuous transport, iontophoresis allows dose titration by adjusting the electric field, which makes personalized dosing feasible. Drug carrier could modify the physicochemical properties of the encapsulated molecule and offer a means to facilitate the percutaneous delivery of difficult-to-uptake substances. Recently, there are some reports about using liposomes, microemulsions and polymeric nanoparticles as vehicles for iontophoretic drug delivery. Niosomes, the nonionic surfactant-based vesicles that are essentially similar in properties to liposomes have been proposed as an alternative to liposomes. Niosomes are more stable and free from other shortcoming of liposomes. Recently, the transdermal delivery of certain drugs using niosomes has been envisaged and niosomes have proved to be superior transdermal nanocarriers. Proniosomes overcome some of the physical stability related problems of niosomes. The proniosomal structure was liquid crystalline-compact niosomes hybrid which could be converted into niosomes upon hydration. The combined use of drug carriers and iontophoresis could offer many additional benefits. The system was evaluated for Encapsulation Efficiency, vesicle size, zeta potential, Transmission Electron Microscopy (TEM), DSC, in-vitro release, ex-vivo permeation across skin and rate of hydration. The use of proniosomal gel as a vehicle for the transdermal iontophoretic delivery was evaluated in-vitro. The characteristics of the applied electric current, such as density, type, frequency, and on/off interval ratio were observed. The study confirms the synergistic effect of proniosomes and iontophoresis in improving the transdermal permeation profile of selected analgesic drug. It is concluded that proniosomal gel can be used as a vehicle for transdermal iontophoretic drug delivery under suitable electric conditions. <p class="card-text"><strong>Keywords:</strong> <a
