The possible geometrical structures and relative stabilities of semiconductor microclusters Ga.P.(n=1-4) were studied by virtue of density functional calculatio
Fifteen new triazole compounds containing thiophene groups were synthesized and their structures were confirmed by means of 1H NMR, IR, MS spectroscopies and el
A CFD code has been developed based on the conservation principles describing gas and solid flow in fluidized beds. This code is employed to simulate not only t
The transformation from graphite to turbostratic graphite by means of the treatment with high-energy ball milling was investigated by X-ray powder diffraction m
