The low dimensional periodic structures in high-dimensional materials such as two-dimensional planar stacking structure one-dimensional chain stacking structure lead to many novel physical phenomena. For example the periodic two-dimensional…
TRDN-2 molecular sieve is a silicon aluminate crystal product with established three-dimensional pore framework, and the pore size of the crystal is 0.9 nm. It is a special molecular sieve for the elimination of N2O from raw gas in cryogenic air sepa…
Bearings used in automobiles, the most demanding speed is the turbocharger bearing, which requires the bearing to have good acceleration reactivity, as well as low torque, low vibration, and low-temperature rise under high-speed rotation.…
