Calcium hydroxide with uniform diameters about 50--100 nm was firstly prepared under moderate condition by adding different kinds of hydrosoluble polymers. From
The reactions of 18-crown-6 with each of K2[M(mnt)2](M=Zn, Hg; mnt=1,2-dicyanoethene-1,2-dithiolate, C2S2(CN)2-2) were studied and novel complexes [K(18-C-6)]2[
The design and the synthesis of two conjugated donor-acceptor imidazole derivatives(1, 2) were carried out for second-order nonlinear optics. The thermal proper
A series of GaN layers was grown on sapphire (0001) substrates under various growth conditions by means of the molecular beam epitaxy(MBE) method, the optical c
There is a classic experiential rule about 1,2-diol RCR1 (OH) CR1 (OH) R ( R1 = H or methyl), that is,the proton chemical shift of the α-R1 group at the hydrox
