Neuropathy is a common complication of obesity. In this regard, the content of neurotrophins in such patients is of particular interest. Neurotrophins are the proteins that regulate neuron survival and neuroplasticity and include brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF). However, the risk of complications depends on the metabolic type of obesity. Metabolically unhealthy obesity (MUHO) is associated with a high risk of complications, while this is not the case with metabolically healthy obesity (MHO). Therefore, the aim of our work was to study the effect of the obesity metabolic type on serum neurotrophins levels. Patients, materials, methods. The study included 134 healthy donors and 104 obese patients. Depending on the metabolic type of obesity, the obese patients were divided into subgroups with MHO (n=40) and MUHO (n=55). In the blood serum, the concentration of BDNF and NGF was determined. In addition, the content of adipokines (leptin, asprosin, resistin, adiponectin), myokines (irisin, myostatin, osteocrin), indicators of carbohydrate, and lipid metabolism were measured. Correlation analysis revealed the relationship between the studied parameters. Results. We found that serum BDNF concentration was not different between obese patients and healthy donors, regardless of obesity metabolic type. At the same time, in obese patients, there was a decrease in serum NGF level versus control. A similar trend was characteristic of both MHO and MUHO. However, MUHO patients had a higher NGF level than MHO patients. The literature indicates that obesity is associated with an increase in the plasma concentration of NGF. It can be assumed that in obesity, there is a violation of NGF storage in platelets, which accelerates neurotrophin degradation. We found that BDNF concentration correlated with irisin levels in MUHO patients. Healthy donors had a weak association between NGF and VEGF levels. No such association was found in obese patients, but there was an association between NGF and leptin concentrations. In MHO, the concentration of NHF correlated with the content of leptin, irisin, osteocrin, insulin, and the HOMA-IR index. But in MUHO patients, we found only the relationship between NGF and adipokines (leptin, asprosin). It can be assumed that in patients with MHO, the replenishment of serum NGF occurs under the influence of muscle and adipose tissue. In the MUHO patients only the effect of adipose tissue on NGF was observed. Conclusion. Obesity, regardless of metabolic type, is associated with a decrease in serum NGF concentration. We showed that muscle and adipose tissues make a significant contribution to the serum NGF pool in the MHO patients. In MUHO there is no effect of muscle on the NGF level, but the effect of adipose tissue remains. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neurotrophins" title="neurotrophins">neurotrophins</a>, <a href="https://publications.waset.org/abstracts/search?q=nerve%20growth%20factor" title=" nerve growth factor"> nerve growth factor</a>, <a href="https://publications.waset.org/abstracts/search?q=NGF" title=" NGF"> NGF</a>, <a href="https://publications.waset.org/abstracts/search?q=brain-derived%20neurotrophic%20factor" title=" brain-derived neurotrophic factor"> brain-derived neurotrophic factor</a>, <a href="https://publications.waset.org/abstracts/search?q=BDNF" title=" BDNF"> BDNF</a>, <a href="https://publications.waset.org/abstracts/search?q=obesity" title=" obesity"> obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolically%20healthy%20obesity" title=" metabolically healthy obesity"> metabolically healthy obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolically%20unhealthy%20obesity" title=" metabolically unhealthy obesity"> metabolically unhealthy obesity</a> </p> <a href="https://publications.waset.org/abstracts/145328/serum-neurotrophins-in-different-metabolic-types-of-obesity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145328.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">100</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">80</span> Blood Microbiome in Different Metabolic Types of Obesity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Irina%20M.%20Kolesnikova">Irina M.

It is accepted to distinguish between metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUHO). MUHO patients have a high risk of metabolic disorders, insulin resistance, and diabetes mellitus. Among the other things, the gut microbiota also contributes to the development of metabolic disorders in obesity. Obesity is accompanied by significant changes in the gut microbial community. In turn, bacterial translocation from the intestine is the basis for the blood microbiome formation. The aim was to study the features of the blood microbiome in patients with various metabolic types of obesity. Patients, materials, methods. The study included 116 healthy donors and 101 obese patients. Depending on the metabolic type of obesity, the obese patients were divided into subgroups with MHO (n=36) and MUHO (n=53). Quantitative and qualitative assessment of the blood microbiome was based on metagenomic analysis. Blood samples were used to isolate DNA and perform sequencing of the variable v3-v4 region of the 16S rRNA gene. Alpha diversity indices (Simpson index, Shannon index, Chao1 index, phylogenetic diversity, the number of observed operational taxonomic units) were calculated. Moreover, we compared taxa (phyla, classes, orders, and families) in terms of isolation frequency and the taxon share in the total bacterial DNA pool between different patient groups. Results. In patients with MHO, the characteristics of the alpha-diversity of the blood microbiome were like those of healthy donors. However, MUHO was associated with an increase in all diversity indices. The main phyla of the blood microbiome were Bacteroidetes, Firmicutes, Proteobacteria, and Actinobacteria. Cyanobacteria, TM7, Thermi, Verrucomicrobia, Chloroflexi, Acidobacteria, Planctomycetes, Gemmatimonadetes, and Tenericutes were found to be less significant phyla of the blood microbiome. Phyla Acidobacteria, TM7, and Verrucomicrobia were more often isolated in blood samples of patients with MUHO compared with healthy donors. Obese patients had a decrease in some taxonomic ranks (Bacilli, Caulobacteraceae, Barnesiellaceae, Rikenellaceae, Williamsiaceae). These changes appear to be related to the increased diversity of the blood microbiome observed in obesity. An increase of Lachnospiraceae, Succinivibrionaceae, Prevotellaceae, and S24-7 was noted for MUHO patients, which, apparently, is explained by a magnification in intestinal permeability. Conclusion. Blood microbiome differs in obese patients and healthy donors at class, order, and family levels. Moreover, the nature of the changes is determined by the metabolic type of obesity. MUHO linked to increased diversity of the blood microbiome. This appears to be due to increased microbial translocation from the intestine and non-intestinal sources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blood%20microbiome" title="blood microbiome">blood microbiome</a>, <a href="https://publications.waset.org/abstracts/search?q=blood%20bacterial%20DNA" title=" blood bacterial DNA"> blood bacterial DNA</a>, <a href="https://publications.waset.org/abstracts/search?q=obesity" title=" obesity"> obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolically%20healthy%20obesity" title=" metabolically healthy obesity"> metabolically healthy obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolically%20unhealthy%20obesity" title=" metabolically unhealthy obesity"> metabolically unhealthy obesity</a> </p> <a href="https://publications.waset.org/abstracts/145332/blood-microbiome-in-different-metabolic-types-of-obesity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145332.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">163</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">79</span> Dipole and Quadrupole Scattering of Ultra Short Pulses on Metal Nanospheres</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sergey%20Svita">Sergey Svita</a>, <a href="https://publications.waset.org/abstracts/search?q=Valeriy%20Astapenko"> Valeriy Astapenko</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The presentation is devoted to the theoretical analysis of ultrashort electromagnetic pulses (USP) scattering on metallic nanospheres in a dielectric medium in the vicinity of surface plasmon resonance due to excitation of dipole and quadrupole surface plasmons. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=surface%20plasmon" title="surface plasmon">surface plasmon</a>, <a href="https://publications.waset.org/abstracts/search?q=scattering" title=" scattering"> scattering</a>, <a href="https://publications.waset.org/abstracts/search?q=metallic%20%20nanosphere" title=" metallic nanosphere"> metallic nanosphere</a> </p> <a href="https://publications.waset.org/abstracts/27368/dipole-and-quadrupole-scattering-of-ultra-short-pulses-on-metal-nanospheres" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27368.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">379</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">78</span> Modern Problems of Russian Sport Legislation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yurlov%20Sergey">Yurlov Sergey</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The author examines modern problems of Russian sport legislation and whether it need to be changed in order to allow all sportsmen to participate, train and have another sportsmen’s rights as Russian law mandates.

In particular, the acoustic emission phenomenon lies in the generation of acoustic waves resulted from the reconstruction of material internal structures. This phenomenon is observed at various physicochemical transformations, in particular, at those accompanying hydrogenation processes of metals or intermetallic compounds that make it possible to study parameters of these transformations through recording and analyzing the acoustic signals. It has been known that at the interaction between metals or inter metallides with hydrogen the most intensive acoustic signals are generated as a result of cracking or crumbling of an initial compact powder sample as a result of the change of material crystal structure under hydrogenation. This work is dedicated to the study into changes occurring in metallic titanium samples at their interaction with hydrogen and followed by acoustic emission signals. In this work the subjects for investigation were specimens of metallic titanium in two various initial forms: titanium sponge and fine titanium powder made of this sponge. The kinetic of the interaction of these materials with hydrogen, the acoustic emission signals accompanying hydrogenation processes and the structure of the materials before and after hydrogenation were investigated. It was determined that in both cases interaction of metallic titanium and hydrogen is followed by acoustic emission signals of high amplitude generated on reaching some certain value of the atomic ratio [H]/[Ti] in a solid phase because of metal cracking at a macrolevel. The typical sizes of the cracks are comparable with particle sizes of hydrogenated specimens. The reasons for cracking are internal stresses initiated in a sample due to the increasing volume of a solid phase as a result of changes in a material crystal lattice under hydrogenation. When the titanium powder is used, the atomic ratio [H]/[Ti] in a solid phase corresponding to the maximum amplitude of an acoustic emission signal are, as a rule, higher than when titanium sponge is used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acoustic%20emission%20signal" title="acoustic emission signal">acoustic emission signal</a>, <a href="https://publications.waset.org/abstracts/search?q=cracking" title=" cracking"> cracking</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogenation" title=" hydrogenation"> hydrogenation</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20specimen" title=" titanium specimen"> titanium specimen</a> </p> <a href="https://publications.waset.org/abstracts/62156/acoustic-emission-for-investigation-of-processes-occurring-at-hydrogenation-of-metallic-titanium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62156.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">386</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">74</span> Web-Content Analysis of the Major Spanish Tourist Destinations Evaluation by Russian Tourists</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Polkanova">Natalia Polkanova</a>, <a href="https://publications.waset.org/abstracts/search?q=Sergey%20Kazakov"> Sergey Kazakov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the research, we proposed the set of factors of tourist destinations attractiveness in Spain and determined the factors that have the greatest impact on the positive perception of the tourist destination by Russian tourists; also, we examined what factors create the willingness for Russians to recommend this tourist destination to their friends and relatives.

The material behavior under such extreme deformation conditions is not studied well and thus, the microstructural examinations of the friction-stir welded materials represent an essential academic interest. Moreover, a clear understanding of the microstructural mechanisms operating during FSW should improve our understanding of the microstructure-properties relationship in the FSWed materials and thus enables us to optimize their service characteristics. Despite extensive research in this field, the microstructural behavior of some important structural materials remains not completely clear. In order to contribute to this important work, the present study was undertaken to examine the grain structure evolution during the FSW of 6061-T6 aluminum alloy. To provide an in-depth insight into this process, the electron backscatter diffraction (EBSD) technique was employed for this purpose. Microstructural observations were conducted by using an FEI Quanta 450 Nova field-emission-gun scanning electron microscope equipped with TSL OIMTM software. A suitable surface finish for EBSD was obtained by electro-polishing in a solution of 25% nitric acid in methanol. A 15° criterion was employed to differentiate low-angle boundaries (LABs) from high-angle boundaries (HABs). In the entire range of the studied FSW regimes, the grain structure evolved in the stir zone was found to be dominated by nearly-equiaxed grains with a relatively high fraction of low-angle boundaries and the moderate-strength B/-B {112}<110> simple-shear texture. In all cases, the grain-structure development was found to be dictated by an extensive formation of deformation-induced boundaries, their gradual transformation to the high-angle grain boundaries. Accordingly, the grain subdivision was concluded to the key microstructural mechanism. Remarkably, a gradual suppression of this mechanism has been observed at relatively high welding temperatures. This surprising result has been attributed to the reduction of dislocation density due to the annihilation phenomena. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electron%20backscatter%20diffraction" title="electron backscatter diffraction">electron backscatter diffraction</a>, <a href="https://publications.waset.org/abstracts/search?q=friction-stir%20welding" title=" friction-stir welding"> friction-stir welding</a>, <a href="https://publications.waset.org/abstracts/search?q=heat-treatable%20aluminum%20alloys" title=" heat-treatable aluminum alloys"> heat-treatable aluminum alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a> </p> <a href="https://publications.waset.org/abstracts/130602/grain-structure-evolution-during-friction-stir-welding-of-6061-t6-aluminum-alloy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130602.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">236</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">70</span> The Quotation-Based Algorithm for Distributed Decision Making</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gennady%20P.%20Ginkul">Gennady P.

It is also shown that energy dissipation in the QDE-MNP system is relatively weak with the probability of the photon emission being about 0.75, a number which, rather surprisingly, does not explicitly depend on the metal absorption characteristics.

The basic performance characteristics of magnetically controlled MEMS switches (service life, sensitivity, contact resistance, fast response) are largely determined by the flexible electrode design.

MCMEMS switches are a promising alternative to Hall sensors and reed switches. The most important parameter for MCMEMS is the contact resistance, which should have a minimum value and is to be stable for the entire duration of service life. The value and stability of the contact resistance is mainly determined by the contact coating material. This paper presents the research results of a contact coating based on nanoscale ruthenium films obtained by electrolytic deposition. As a result of the performed investigations, the deposition modes of ruthenium films are chosen, the regularities of the contact resistance change depending on the number of contact switching, and the coating roughness are established. It is shown that changing the coating roughness makes it possible to minimize the contact resistance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contact%20resistance" title="contact resistance">contact resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=electrode%20coating" title=" electrode coating"> electrode coating</a>, <a href="https://publications.waset.org/abstracts/search?q=electrolytic%20deposition" title=" electrolytic deposition"> electrolytic deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetically%20controlled%20MEMS" title=" magnetically controlled MEMS"> magnetically controlled MEMS</a> </p> <a href="https://publications.waset.org/abstracts/99675/ruthenium-based-nanoscale-contact-coatings-for-magnetically-controlled-mems-switches" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99675.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">182</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">57</span> Switching to the Latin Alphabet in Kazakhstan: A Brief Overview of Character Recognition Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ainagul%20Yermekova">Ainagul Yermekova</a>, <a href="https://publications.waset.org/abstracts/search?q=Liudmila%20Goncharenko"> Liudmila Goncharenko</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Baghirzade"> Ali Baghirzade</a>, <a href="https://publications.waset.org/abstracts/search?q=Sergey%20Sybachin"> Sergey Sybachin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article, we address the problem of Kazakhstan's transition to the Latin alphabet. The transition process started in 2017 and is scheduled to be completed in 2025. In connection with these events, the problem of recognizing the characters of the new alphabet is raised. Well-known character recognition programs such as ABBYY FineReader, FormReader, MyScript Stylus did not recognize specific Kazakh letters that were used in Cyrillic. The author tries to give an assessment of the well-known method of character recognition that could be in demand as part of the country's transition to the Latin alphabet. Three methods of character recognition: template, structured, and feature-based, are considered through the algorithms of operation. At the end of the article, a general conclusion is made about the possibility of applying a certain method to a particular recognition process: for example, in the process of population census, recognition of typographic text in Latin, or recognition of photos of car numbers, store signs, etc. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=text%20detection" title="text detection">text detection</a>, <a href="https://publications.waset.org/abstracts/search?q=template%20method" title=" template method"> template method</a>, <a href="https://publications.waset.org/abstracts/search?q=recognition%20algorithm" title=" recognition algorithm"> recognition algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=structured%20method" title=" structured method"> structured method</a>, <a href="https://publications.waset.org/abstracts/search?q=feature%20method" title=" feature method"> feature method</a> </p> <a href="https://publications.waset.org/abstracts/138734/switching-to-the-latin-alphabet-in-kazakhstan-a-brief-overview-of-character-recognition-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138734.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">186</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">56</span> A Neural Network Classifier for Identifying Duplicate Image Entries in Real-Estate Databases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sergey%20Ermolin">Sergey Ermolin</a>, <a href="https://publications.waset.org/abstracts/search?q=Olga%20Ermolin"> Olga Ermolin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A Deep Convolution Neural Network with Triplet Loss is used to identify duplicate images in real-estate advertisements in the presence of image artifacts such as watermarking, cropping, hue/brightness adjustment, and others.

The implemented method is used in a Proof-of-Concept project in the real-estate industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=visual%20recognition" title="visual recognition">visual recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=convolutional%20neural%20networks" title=" convolutional neural networks"> convolutional neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=triplet%20loss" title=" triplet loss"> triplet loss</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20batch%20normalization%20with%20dropout" title=" spatial batch normalization with dropout"> spatial batch normalization with dropout</a>, <a href="https://publications.waset.org/abstracts/search?q=duplicate%20removal" title=" duplicate removal"> duplicate removal</a>, <a href="https://publications.waset.org/abstracts/search?q=advertisement%20technologies" title=" advertisement technologies"> advertisement technologies</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20benchmarking" title=" performance benchmarking"> performance benchmarking</a> </p> <a href="https://publications.waset.org/abstracts/73918/a-neural-network-classifier-for-identifying-duplicate-image-entries-in-real-estate-databases" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73918.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">338</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">55</span> Recovery of Rare Earths and Scandium from in situ Leaching Solutions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maxim%20S.%20Botalov">Maxim S.

As the orebody containing uranium most often contains a considerable value of other metals, particularly rare earth metals it has rendered feasible to recover the REM from the barren ISL solutions, from which the major uranium content has been removed. Ural Federal University (UrFU, Ekaterinburg, Russia) have performed joint research on the development of industrial technologies for the extraction of REM and Scandium compounds from Uranium ISL solutions. Leaching experiments at UrFU have been supported with multicomponent solution model. The experimental work combines solvent extraction with advanced ion exchange methodology in a pilot facility capable of treating 500 kg/hr of solids. The pilot allows for the recovery of a 99% concentrate of scandium oxide and collective concentrate with over 50 % REM content, with further recovery of heavy and light REM concentrates (99%). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extraction" title="extraction">extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=ion%20exchange" title=" ion exchange"> ion exchange</a>, <a href="https://publications.waset.org/abstracts/search?q=rare%20earth%20elements" title=" rare earth elements"> rare earth elements</a>, <a href="https://publications.waset.org/abstracts/search?q=scandium" title=" scandium"> scandium</a> </p> <a href="https://publications.waset.org/abstracts/88125/recovery-of-rare-earths-and-scandium-from-in-situ-leaching-solutions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88125.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">232</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">54</span> In Situ Laser-Induced Synthesis of Copper Microstructures with High Catalytic Properties and Sensory Characteristics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maxim%20Panov">Maxim Panov</a>, <a href="https://publications.waset.org/abstracts/search?q=Evgenia%20Khairullina"> Evgenia Khairullina</a>, <a href="https://publications.waset.org/abstracts/search?q=Sergey%20Ermakov"> Sergey Ermakov</a>, <a href="https://publications.waset.org/abstracts/search?q=Oleg%20Gundobin"> Oleg Gundobin</a>, <a href="https://publications.waset.org/abstracts/search?q=Vladimir%20Kochemirovsky"> Vladimir Kochemirovsky</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The continuous in situ laser-induced catalysis proceeding via generation and growth of nano-sized copper particles was discussed. Also, the simple and lost-cost method for manufacturing of microstructural copper electrodes was proposed. The electrochemical properties of these electrodes were studied by cyclic voltammetry and impedance spectroscopy. The surface of the deposited copper structures (electrodes) was investigated by X-ray photoelectron spectroscopy and atomic force microscopy. These microstructures are highly conductive and porous with a dispersion of pore size ranging from 50 nm to 50 μm. An analytical response of the fabricated copper electrode is 30 times higher than those observed for a pure bulk copper with similar geometric parameters. A study of sensory characteristics for hydrogen peroxide determination showed that the value of Faraday current at the fabricated copper electrode is 2-2.5 orders of magnitude higher than for etalon one. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laser-induced%20deposition" title="laser-induced deposition">laser-induced
