The efficient use of renewable energy sources requires development of new electrocatalytic
materials for electrochemical energy storage systems, particularly fuel cells. To increase durability of
high temperature polymer electrolyte fuel cell (HT-PEMFC), Pt/carbon black based catalysts should
be replaced by more durable ones, for example Pt/carbon nanofibers (CNF). Here, we report for the
first time the quantitative ascorbic acid ...

Thin-film nanocrystalline zinc oxide electrodes were fabricated by electrochemical deposition of ZnO on FTO-coated glass slides. ZnO electrodes were promoted by CdO coating on top of ZnO in amounts corresponding to 0.8, 0.1, and 0.05 C cm−2 in electric units. Modification of ZnO by a small amount of CdO, corresponding to 0.05 C cm−2, shifts the ...

We consider the “Matthew effect” in the citation process which leads to reallocation (or misallocation) of the citations received by scientific papers within the same journals. The case when such reallocation correlates with a country where an author works is investigated. Russian papers in chemistry and physics published abroad were examined. We found that in ...

Over the past few decades, quantitative methods of evaluating scientific work, including the citation index of research publications, have been finding expanding applications. The citation index underlies not only the evaluation of the efficiency of individual scientists but also the rating of scientific editions. The authors share their experience in bibliometric research based on the ...

Abstract:The current state, issues, tasks, and pathways for development of a domestic chemical-fiber branch integrated into the entire Russian chemical and petrochemical complex were analyzed because this branch of the domestic economy is understood to be a single holistic organism through the arteries of which chemicals, reagents, products, and recycled wastes circulate.

The concept of using redox-active ligands, which has become extremely widespread in organometallic chemistry, is often considered from 'their effect on the metal center properties' point of view and 'how to modify the ligands'. In this paper, we present the reverse side of this effective approach - a dramatic change of redox properties of ligands ...

During the summer of 1900, the Chemical Section of the Society for the Promotion of Russian Industry and Commerce in Warsaw published a very special booklet in which prominent philologists debated proposals concerning adjustments to chemical nomenclature. Several issues were discussed, including systems of classification of chemical compounds, new specialist terms, and which element names ...

Nanosized bimetallic PtMo, PtFe and trimetallic PtMoSn catalysts deposited on highly
dispersed carbon black Vulcan XC-72 were synthesized from the cluster complex compounds
PtCl(P(C6H5)3)(C3H2N2(CH3)2)Mo(C5H4CH3)(CO)3, Pt(P(C6H5)3)(C3N2H2(CH3)2)Fe(CO)3(COC6H5
C2C6H5), and PtCl(P(C6H5)3)(C3N2H2(CH3)2)C5H4CH3Mo(CO)3SnCl2, respectively. Structural characteristics
of these catalysts were studied using X-ray diffraction (XRD), microprobe energy dispersive
spectroscopy (EDX), and transmission electron microscopy (TEM). The synthesized catalysts were
tested in aqueous 0.5 M H2SO4 in ...

The further development of high temperature polymer electrolyte membrane (HT-PEM) fuel
cells largely depends on the improvement of all components of the membrane–electrode assembly
(MEA), especially membranes and electrodes. To improve the membrane characteristics, the cardopolybenzimidazole
(PBI-O-PhT)-based polymer electrolyte complex doped with phosphoric acid is
reinforced using an electrospun m-PBI mat. As a result, the PBI-O-PhT/es-m-PBInet nH3PO4 reinforced
