В статье рассмотрено влияние общецивилизационных трендов развития (цифровизация, коммерциализация и др.), а также внутренних факторов (изменение статусно-ролевых ожиданий и предписаний) на институт образования. Перспективы его дальнейшего развития не могут рассматриваться исключительно в критериях экономического подхода, поскольку этот институт вып...
Enhanced negative thermal expansion (NTE) properties are achieved by introducing a little amount of boron in the Fe43Mn28Ga28.97B0.03 alloy. As a result, this alloy shows a giant NTE coefficient of alpha(1) = -79.7 x 10(-6) K-1 in a wide temperature range from 277 K to 136 K. Compared to the NTE characteristics in Fe43Mn28Ga29, the NTE operation te...

Persulfate (S2O82-; PS) has been used with zerovalent iron (ZVI) for the remediation of various contaminants. However, the passive layer of commercial ZVI limitates the corrosion of ZVI and reaction with PS. In our initial attempt, we mechanically combined Na2S2O8 and micro-sized ZVI by simple ball milling to improve the reaction of PS and ZVI. The...

We report a copper-catalyzed enatiotopic-group-selective allylation of gem-diborylalkanes with allyl bromides. The combination of copper(I) bromide and H-8-BINOL derived phosphoramidite ligand proved to be the most effective catalytic system to provide various enantioenriched homoallylic boronate esters, containing a boron-substituted stereogenic c...
The synthesis of green products using renewable bio-monomers has become a research trend with the requirement of sustainable development. In this work, we reported a green pathway to synthesize poly(isosorbide carbonate) (PIC) via one-step melt polycondensation of biomass-derived isosorbide (ISB) and CO2-derived dimethyl carbonate (DMC) catalyzed b...

Agrobacterium spp. are important plant pathogens that are the causative agents of crown gall or hairy root disease. Their unique infection strategy depends on the delivery of part of their DNA to plant cells. Thanks to this capacity, these phytopathogens became a powerful and indispensable tool for plant genetic engineering and agricultural biotech...
