Based on the reaction mechanism of resid hydrodemetallization,a new catalyst carrier was designed and prepared.As compared with the similar type of catalyst car
A new technique is proposed to solve the blind source separation (BSS) given only a single channel observation. The basis functions and the density of the coeff
A kind of novel multi-layer piezoelectric actuator is proposed and integrated with controllable constrained damping treatment to perform hybrid Vibration contro
Future steam turbines will use hollow structures so that the turbine inlet temperature can be increased to improve the thermal efficiency. These hollow structur
SiO2 colloidal spheres were synthesized by St(o)ber method. In order to enhance surface charge of the SiO2 spheres, they were modified with succinic acid. Scann
The insertion reaction mechanism of CBr2 with CH3CH2O has been studied by using the B3LYP/6-311G(d) and CCSD(T)/6-311G(d) at single point. The geometries of rea
Idiopathic pulmonary arterial hypertension (IPAH) is a rare disease of unknown etiology. The exact pathogenesis of pulmonary arterial hypertension is still not
A simple size-exclusion high-performance liquid chromatographic method was developed for rapid molecular mass screening to determine the average molecular mass,
In this paper we report a recent study on the beam self-cleaning behavior occurred during the ultrashort laser pulse filamentation process. The propagation of a
