We report a novel simple one-pot strategy for fabricating pure and highly planar silver (Ag) crystal belts. Unique single-crystal Ag belts (high width-to-thickness ratio ~50) were successfully synthesized in high yield (80 wt%) by reducing AgNO3 using N,N,N',N'-tetramethylethylenediamine (TEMED) as a reducing and a structure-determining agent in the presence of polyethylene glycol (PEG) under m...

Synthesis of silver nitrate using the chemical reduction method with variations in heating time for 1 hour, 2 hours and 3 has been successfully carried out. This study aims to determine effect on phase structure, elemental concentration, morphology, mass percentage elements. The synthesis process was out by a mixture nitric acid at T = 85 °C hours, then evaporation 125 10 minutes. results XRF a...

Pt(acac)2, AgNO3, Cu(acac)2, Fe(acac)2, Pd(acac)2, RhCl3, Co(acac)2 poly(vinylpyrrolidone) (PVP; Mw 8000), were purchased from Alfa Aesar Co.Ltd, and Bi(NO3)2, KI, KBr, KCl, tris (hydroxymethyl ) aminomethane, HCHO solution (37 wt%), formamide, and acetone were purchased from Sinopharm Chemical Reagent Co. Ltd . All the chemicals were analytical grade and used as received without any purificati...

The uptake of silver by an experimentally derived silver-resistant Klebsiella pneumoniae strain was three to four times lower than the uptake by a susceptible strain. Spheroplasts of the two strains showed no difference in uptake. AgNO3 at a concentration of 40 micrograms/ml decreased the succinate dehydrogenase activity in susceptible and resistant strains by 100 and 18%, respectively. More th...
