Optimized Dehydrogenation of Magnesium Hydride with Fe and Cu Additives
Authors: Gbenebor Oluwashina , Popoola Abimbola Patricia 
Published: September 2024

Solid state hydrogen storage with the use of MgH2 has gained widespread attention because of its good reversible storage capacity. This metal hydride however slowly releases hydrogen at high temperatures ranging between 325 – 375 oC. An important feature required of MgH2 is its ability to commence hydrogen release at a fast rate and reduced temperature. Transition metal-containing alloys/compounds having either Fe or Cu as the principal element have been used to improve the dissociation of hydrogen from MgH2. Studies involving the use of each metal in its elemental form as an additive are minimal. This study investigated the catalytic effects of elemental Fe and Cu on the hydrogen release performance of MgH2 for potential applications in transportation and power generation. It was observed that MgH2/Fe had a better dehydrogenation performance; the temperature of onset of MgH2/Fe and MgH2/Cu dehydrogenation were 205, and 215 oC which were 98 and 88 oC lower than that for as-received MgH2. The highest amount, 1.9 wt. % H2 was released by MgH2/Fe while 1.44 wt. % H2 was released by MgH2/Cu. The activation energy for dehydrogenation was reduced from 150.5 kJ/mol for as-received MgH2 to 89.8 and 79.8 kJ/mol in MgH2/Cu and MgH2/Fe respectively. It took 18.8 min for as-received MgH2 to commence dehydrogenation while that for MgH2/Fe and MgH2/Cu composites started from 12.2 and 13.4 min respectively. The in-situ formed Fe and Cu in MgH2 after milling acted as active catalytic sites for its improved dehydrogenation with MgH2/Fe behaving better.

Este estudo investigou os desafios enfrentados pelos professores na utilização das Tecnologias Digitais de Informação e Comunicação (TDICs) em sala de aula, com o objetivo de identificar as barreiras e propor possíveis soluções para aprimorar a inclusão digital nas escolas. A pesquisa teve como foco compreender os obstáculos que comprometem a integração eficaz das TDICs no ambiente educacional. Foi utilizada uma metodologia de revisão bibliográfica, que analisou artigos, livros e outros documentos relevantes para o tema. Os resultados mostraram que a falta de formação específica e contínua, aliada à insuficiência de infraestrutura e recursos, são os principais desafios enfrentados pelos docentes. Além disso, foi observada uma resistência cultural ao uso das tecnologias, influenciada pelo medo de que estas possam desumanizar o processo educativo. As considerações finais indicaram que, embora existam obstáculos significativos, é possível superá-los com investimentos em infraestrutura, formação contínua e redes de apoio entre professores. Sugere-se a realização de novos estudos para explorar estratégias de formação eficazes e a criação de políticas públicas que promovam a qualidade da inclusão digital.

PERFECTIONISM AS A PSYCHOLOGICAL PHENOMENON AND THE SPECIFICS OF ITS MANIFESTATION IN ADOLESCENCE
Authors: Шафажинская Н.Е. , Юлина Г.Н. , Калита В.В. 
Published: September 2024

Перфекционизм является одним из наиболее актуальных, широко дискутируемых явлений, непосредственно связанных с имманентно присущей человеку интенцией к достижению высшего уровня своего саморазвития и деятельности в той или иной сфере. Данная тема активно изучается как за рубежом, так и в России, особенно в последнее время, что обусловлено, в частности, ее идентификацией с вопросами социальной успешности личности. В современной психологической науке перфекционизм трактуется как стремление индивида к идеалу, проявляющееся в установлении высоких личных стандартов. Эти стандарты служат ориентиром для достижения наилучших результатов в различных сферах деятельности, будь то духовно-нравственные, интеллектуальные, материальные, морально-этические, эстетические, профессиональные или физические аспекты жизни. Особую значимость изучение феномена перфекционизма имеет для молодежной среды в связи с «нарциссизацией» массовой культуры в эпоху постмодернизма со свойственным ей злоупотреблением современными гедонистическими технологиями удовлетворения потребительской мотивации, хаотической и чрезвычайно изменчивой общественно продуцируемой системой норм и ценностей.
The article is devoted to the theoretical and empirical study of the phenomenon of perfectionism and its features in adolescence. Perfectionism is one of the most relevant, widely debated phenomena directly related to the inherent human intention to achieve the highest levels of self-development and activity in a particular field. This topic, especially recently, has been actively studied both abroad and in Russia, which is due, in particular, to its identification with the social success of the individual. In modern psychology, perfectionism is defined as the pursuit of perfection, as the presence of high individual standards in a subject, according to which he strives to bring the results of any of his activities to match the chosen semantic and life-defining standards — spiritual, moral, intellectual, material, moral, ethical, aesthetic, professional, physical. In the content of the article, the authors emphasize that the study of the phenomenon of perfectionism is of particular importance among young people in connection with the «narcissization» of mass culture in the postmodern era with its characteristic abuse of modern hedonistic technologies to satisfy consumer motivation, chaotic and extremely changeable socially produced system of norms and values.
