a facile mechanochemical-based method for synthesis of copper oxide (cuo) nanoparticles is here by introduced. for this purpose, copper hydroxide powder was synthesized through a facile solution method (cuso4 + 2 na(oh) → cu(oh)2 + na2so4) after which milling of as-prepared cu(oh)2 precursor and nacl resulted in the mechanochemical dehydration of cu(oh)2 and dispersion of cuo nanoparticles into...

The presence of amino acids on the prebiotic Earth, either stemming from endogenous chemical routes or delivered by meteorites, is consensually accepted. Prebiotically plausible pathways to peptides inactivated are still unclear as most oligomerization approaches rely thermodynamically disfavored reactions in solution. Now, a combination prebiotically minerals and mechanochemical activation ena...

The attachment point of the polymer chain to a force-responsive molecular unit (mechanophore) is decisive parameter determining bond scission rate and ultimately mechanochemical reaction outcome. However, such regiochemical substituent effects have not yet been investigated for 9-?-extended anthracene-maleimide Diels-Alder adducts. Here we combine three methods, namely ultrasonication, CoGEF co...

ATP-binding cassette (ABC) transporters serve as importers and exporters for a wide variety of solutes in both prokaryotes and eukaryotes, and are implicated in microbial drug resistance and a number of significant human genetic disorders. Initial crystal structures of the soluble nucleotide binding domains (NBDs) of ABC transporters, while a significant step towards understanding the coupling ...

The field of mechanochemistry is reviewed. A large number of mechanochemical reactions are described as well as industrial applications. INTRODUCTION At the beginning of this century, W. Nernst classified the different fields of chemistry according to the type of energy supplied to the system: thermochemistry, electrochemistry, photochemistry, etc. The name mechanochemistry was applied to the f...

Lithium-ion batteries (LiBs) based on insertion electrodes reach intrinsic capacity limits. Performance improvements and cost reduction require alternative reaction mechanisms novel battery chemistries such as conversion reactions sodium-ion (NaBs), respectively. We here study the formation of Ti1-xVxH2 hydrides (0 ≤ x 1) their electrochemical properties anodes in LiBs NaBs half-cells. Hydrides...

Bismuth niobate solid solutions, BixNbOδ (2.5 ≤ x ≤ 6), have been prepared using a mechanochemical method. The solid solutions were also prepared using a solidstate conventional method for comparison purposes. Bi3NbO7 was successfully obtained via a mechanochemical method at a lower synthesis temperature (milled at 1000 rpm for one hour followed by heating at 700C for 24 h) than the conventiona...

We present the first case of retrograde ablation of the small saphenous vein to treat active venous ulceration. A 73-year-old gentleman with complicated varicose veins of the left leg and a non-healing venous ulcer despite previous successful endovenous treatment to his left great saphenous vein underwent mechanochemical ablation of his small saphenous vein with the ClariVein® system, under loc...
