Optically active aminocyclopropane and its derivatives are ubiquitous subunits of many biologically active natural products , pharmaceuticals , and agrochemicals .Traditional catalytic asymmetric methods rely on [ 2 + 1 ] cycloaddtion of enamine dertivatives and hydro ( carbo ) amination of cyclopropenes .The reactive sites of these substrates n...
Mechanoluminescence ( ML ) is a type of luminescence that can convert the mechanics into light .Because of its unique characteristics , such as mechanics visualization and spatial resolution , ML provides novel thoughts to deal with the critical problems in mechanics sensing .To grasp and master the essence of ML and guide its future design and ...
Triboelectric electrification is a common phenomenon in interfacial friction , in which electrons are continuously transferred , excited , and flowed between two surfaces .Most of the current research on the relationship between triboelectrification and friction force is based on contact resistance ( friction between metal and metal ) , surface ...
Low surface energy coating materials have crucial application prospects in fluid drag reduction , anti-fouling , self-cleaning , and anti-icing due to their unique wettability .The mechanical wear resistance of coating surface was greatly improved , and surface wettability was almost unchanged after 30000 friction cycles under 100 KPa . In addit...
Chinese researchers recently demonstrated an innovative chemical method for engineering diverse layered hydrogels with wet and slippery features at room temperature .Layered hydrogel structures with wet and slippery features that are suitable for a wide range of applications including tissue-like models , soft robots and intelligent devices .” ...
