a new anti-corrosion compound, melamine formaldehyde (mf), was formulated by the addition of proper amount of formaldehyde to melamine under specific conditions. this compound was mixed with a novel nano powder, which was extracted from corn cob ash containing sio2 particles, in order to improve its corrosion inhibition efficiency. this inhibitor provides a high level of protection for steel su...

Active amino acid transport in Stajhylococcus aureus U-71 membrane vesicles is coupled to either cy-glycerol phosphate dehydrogenase or L-lactate dehydrogenase depending upon the growth conditions of the parent cells. Vesicles prepared from cells grown on gluconate as a primary carbon source exhibit an absolute specificity for a-glycerol phosphate as a physiological electron donor for transport...

Molecular vibrations and electron-vibrational interactions are central to the control of biomolecular electron and energy-transfer rates. The vibrational control of molecular electron-transfer reactions by infrared pulses may enable the precise probing of electronic-vibrational interactions and of their roles in determining electron-transfer mechanisms. This type of electron-transfer rate contr...
