V-Pd/γ-Al2O3-TiO2 catalysts with different vanadium contents were prepared by a combined sol-gel and impregnation method.X-ray diffraction(XRD),N2 adsorption-d
In the present study,we have investigated the reducibility of CuO species on CuO-CeO2 catalysts and the influence of CuO species on the catalytic performance fo
A new friedelane-type triterpene named 3β-hydroxyfriedelane-7,12,22-trione, as well as nine known compounds were isolated from the whole stems of Drypetes laci
A novel and very simple colorimetric and fluorometric method for selectively sensing F-was proposed based on 4-bromo-2,6-bis(hydroxymethyl)phenol (BBHMP), which
Pyrochlore titanate oxides, R2Ti2O7(R=Gd3+, Tb3+, Dy3+), were synthesized under mild hydrothermal conditions. The crystal growth of pyrochlore titanate oxides a
tert-Buty1 (R)-3-amino-3-(3-fluoropheny1)propanoate(5) was prepared with conventional debenzylation method. However, the tert-buty1 (R)-3-[(S)-1-phenylethy1-ami
A further understanding of the self-heating of coal was obtained by investigating the crossing point temperature (CPT) of different ranks of coal. The tests wer
Novel methanol-tolerant oxygen-reduction catalysts, iridium-sulphur (Ir-S) chalcogenides with differ ent Ir/S atomic ratios, were synthesized via a precipitatio
In this paper, the propagation of guided thermoelastic waves in laminated orthotropic plates subjected to stress-free, isothermal boundary conditions is investi
