As a new kind of energy storage devices, supercapacitors possess a higher power density, a longer cycle life, a simpler charging circuit, no memory effect and are much safer and maintenance-free. They have broad applications in electric vehicles, mobile communications, defence-related science and technology, and so on. The tribology of low dime...
Harsh environment and changing work conditions (frequent start-stop, low/high speed, and boundary lubrication/dry friction) are the major factors causing the decrease of load carrying capacity, severe wear and poor reliability of friction pairs in mechanical seals. They are also the main challenge in the development of key parts for mechanical s...
The development of practical and efficient chiral catalytic systems for asymmetric organic reactions is one of the most important subjects in synthetic organic chemistry. In general, conformationally rigid chiral ligands have been proven to be extremely useful for the construction of a good oriented and fixed chiral environment around the metal ...
