In this work, casting method was used to fabricate the polyvinyl alcohol (PVA)/ poly ethylene glycol (PEG) nanocomposite with different content of titanium nitrate nanoparticle (TiN NPs). This analyzed use a Spectrophotometry spectral region 200-800 nm. The absorption enhances when added TiN NPs polymeric matrix which may be for various applications such as optoelectronic detector. optical ener...
Rat liver nucleotide pyrophosphatase/phosphodiesterase I (NPP/PDE) catalysed efficiently the transfer of adenylate from ATP to alcohols (methanol, ethanol, propanol, ethylene glycol, glycerol, 2, 2-dichloroethanol and glycerol 2-phosphate), which acted as adenylate acceptors competing with water with different efficiencies. NPP/PDE kinetics in alcohol/water mixtures were accounted for by rate e...
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.
In the course of a study of the effects of micro-beam irradiation of a small portion of a particular cell in culture, it became necessary to devise a technic for following this cell through the processes of fixation and subsequent embedding for electron microtomy. The new procedure has proved more satisfactory for our purposes than the methods previously described by Borysko and Sapranauskas (1...
