in this scientific research, magnesium oxide (mgo) nanoparticles were synthesized from magnesium nitrate and ammonium solutions via microwave@sol-gel process. the structure and the morphology of the synthesized nanoparticles has been identified and characterized by x-ray diffraction (xrd), n2-bet (brunauer-emmett-tell), scanning electron microscopy (sem) and fourier transform infrared (ftir) te...

To provide insight and to identify the occurrence of mechanistic changes in relation to variance in solvent-type, the solvent effects on the rates of solvolysis of three substrates, 2,2,2-trichloro-1,1-dimethylethyl chloroformate, 2,2,2-trichloroethyl chloroformate, and 1-chloroethyl chloroformate, are analyzed using linear free energy relationships (LFERs) such as the extended Grunwald-Winstei...

Assessment of the Role of DNA Damage and Repair in the Survival of Primary Cultures of Rat Cutaneous Keratinocytes Exposed to Bis(2-chloroethyl)sulfide. RIBEIRO, P. L.. MITRA, R. S.. AND BERNSTEIN. I. A. ( I99 1). Tolicol. .4ppl. Phurmacol. Ill, 342-35 1. Toxicity manifests itself as vesication in human skin exposed topically to bis(2-chloroethyl)sulfide (BCES). The destruction of the prolifera...

in this work, zncao2 (zinc oxide-calcium oxide) nanocomposite were synthesized at different temperatures (500-700°c) by sol-gel method based on polymeric network of polyvinyl alcohol (pva). the synthesized samples were characterized by sem/edax, ft-ir and xrd techniques. it was found that synthesized nanocomposites have 1.62, 2.05 and 13.91%wt of cao, respectively. the obtained results show tha...

Reaction with thiol converts the antitumor natural product leinamycin to an episulfonium ion that alkylates the N(7)-position of guanine residues in double-stranded DNA. The sequence specificity for DNA alkylation by this structurally novel compound has not previously been examined. It is reported here that leinamycin shows significant (>10-fold) preferences for alkylation at the 5'-G in 5'-GG ...

A vicinal ethylene bridged S/B frustrated Lewis pair (FLP) in situ generated by a hydroboration reaction of phenyl vinyl sulfide, reacts with p-tert-butylphenylacetylene by ethene/alkyne exchange and subsequent 1,2-addition of a second alkyne equivalent to give a zwitterionic sulfonium/borate product.
