BEIJING , March 30 ( Xinhua ) - - Chinese researchers have designed a cartilage-like lubricated composite with mechanical robustness .According to a research article recently published in the journal ACS Applied Materials and Interfaces . Natural articular cartilages show extraordinary tribological performance based on their penetrated surface l...
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...
