Emergence of this technology alters existing consumption pattern for mineral resources. Today, center stage is taken by such crucial elements as copper, nickel, lithium, cobalt and, of course, REMs. Permanent REM magnets are pivotal to transition to green and renewable energy. Therefore, in new circumstances the global power system needs different approaches to production and supply chains for key natural resources. Russia’s FEC is the world’s second largest (after the USA) producer of power resources and third largest in-country consumer of the same (trailing the USA and China). However, there is no full-cycle production of individual REMs and REM-based alloys inside the country, despite one of the largest mineral resource bases of REMs in the world. A clearly apparent global trend shows that the pace of developing new MR sources and the necessary investments do not match acceleration in production of such high tech products as solar batteries, wind power generators (WPG), and electric cars. This is due to the fact that many key MRs (especially REMs) come from a small number of producers located in just a few countries. With this in mind, the paper presents a study of the production chain of NdFeB magnets and electric engines based on them, seen as essential to development of Russia’s wind power. Also, economic feasibility of some generation technologies in connection with the ever-increasing power of generators is considered. Basic topologies of electric machines are analyzed as well. The key question of the study is whether rare earth MRs become an incentive for transition to a new energy system in Russia or a bottleneck in the process.</p></div>","PeriodicalId":18283,"journal":{"name":"Materials Science for Energy Technologies","volume":"7 ","pages":"Pages 107-114"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42519947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different composites were prepared by varying the concentration of AgNO₃, resulting in rGS-AgNPs composites with concentrations of 0.9 × 10⁻³ mM, 1.8 × 10⁻³ mM, and 2.7 × 10⁻³ mM.

The composites exhibited a firm binding of the surfactant and AgNPs on the surface of rGO nanosheets, resulting in efficient anti-biofilm and photocatalytic activity. The size of the supported AgNPs on rGO/SL was found to be 8–10 nm. The rGS-AgNPs composites displayed significantly improved anti-biofilm and photocatalytic performance, attributed to the increased surface area of AgNPs. Moreover, the photocatalytic efficiency of the rGS-AgNPs composites reached 96.48 % within 60 min, outperforming pure AgNPs.

Therefore, it is necessary to process this dye waste before it enters water bodies so that it does not damage the environment. The aim of this research was to optimize the function of magnetite (Fe₃O₄) extracted from iron sand combined with TiO₂ for degrading methylene blue dye. The iron sand was extracted using a bar magnet, sieved, washed, milled, and dried. Iron sand (20 g) was converted into magnetite using the co-precipitation method with a stirring speed of 800 rpm at a temperature of 80 °C for 30 min. Magnetite was mixed with TiO₂ with 30 % ethanol using a mechanical stirring method. The characteristics of Fe₃O₄-TiO₂ photocatalyst were tested using XRD, SEM-EDX and VSM. According to the XRD data, the crystal size of the Fe₃O₄-TiO₂ photocatalyst was below 40 nm. The presence of Fe and Ti in the photocatalyst material and their even distribution were determined by SEM-EDX testing. Through VSM, it was confirmed that soft magnetic properties were present in this material. The performance of the Fe₃O₄-TiO₂ photocatalyst in the degradation of methylene blue dye was analyzed using a UV–Vis spectrophotometer. The test results showed that the performance of the photocatalyst improved as the contact time increased and was marked by a decrease in the optical absorption intensity; the best performance of the Fe₃O₄-TiO₂ photocatalyst reached 93 %. Therefore, it can be concluded that iron sand as part of the photocatalyst material, play a role in the photodegradation of methylene blue dye.</p></div>","PeriodicalId":18283,"journal":{"name":"Materials Science for Energy Technologies","volume":"7 ","pages":"Pages 374-380"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2589299124000090/pdfft?md5=d9d3332c0fd92e7afa8de3ede89fc096&pid=1-s2.0-S2589299124000090-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141396133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A kinetic study of biomass confirmed that activation energy increased substantially (34.37–90.34 and 22.74–63.92 kJ mol⁻¹ for MWS and CNW, respectively) by varying the reaction order. The outcomes of the pyrolysis process revealed that elevating the pyrolysis temperature from 400 to 800 °C resulted in a decrease in the yield of biochar, accompanied by an increase in its carbon content. XRD study of biochar established that rising pyrolysis temperature caused a change in the mineral content of biochar. HHV and bulk density of biochar were found to be increased by increasing pyrolysis temperature from 400–800 °C.
