Cobalt-based ZIF-68 and ZIF-69 as the precursors of non-platinum electrocatalysts for oxygen reduction

We report the microwave-assisted synthesis of Co-based ZIF-68 and ZIF-69 zeolitic imidazolate frameworks, which were enriched with iron(ii) acetate and 1,10-phenanthroline and then pyrolyzed to form heterogeneous catalysts. The materials demonstrated high activity in oxygen reduction and suitability as Pt-free catalysts for low-temperature fuel cell

Automatic Text Processing and Linguistic Modeling as Instruments for Solving Problems of Text Attribution

This paper focuses on the approbation of an integrative method of attribution text analysis in Russian, based on a combination of the results of an interpretive study of the material and objectification of these results through mathematical statistics.В статье рассматривается апробация интегративной методики атрибуционного анализа текста на русском языке
