A case study is given of dendritic growth during zinc electrolysis in conditions that promote it. Subject the main interest was how parameters affect duration dendrites life. The selected set did provide a surprisingly regular dendrite?s life, i.e., period from start until detachment cathode. Dendrite?s proceed with lowering current efficiency, and end life manifested by intensive hydrogen evol...
Background and Objective: Sulfur mustard is a potent chemical vesicant warfare agent that remains a significant military and civilian threat. Inhalation of sulfur mustard gas causes inflammation and injury to airways and bronchioles. Mast cells promote allergic reactions when exposed to some chemical compounds such as HD. Hexamethylenetetramine has been shown to protect human lung cells against...
Chitosan and chitosan/hexamethylenetetramine (HMT) macrospheres were prepared respectively by dropping the solution of chitosan chitosan/HMT (in wt/wt ratios 1:1 1:3) in aq. NaOH solution. Here, HMT served as an additional nitrogen precursor for situ N-doping with derived activated carbon (AC). The as-formed impregnated using ZnCl2, freeze-dried carbonized at 500 °C under inert atmosphere to yi...
A simple wet-chemical synthesis method was developed to fabricate Zinc oxide micro-rod clusters. The process involved the rapid dilution of a zinc-bearing alkaline solution at 150°C in convection oven on indium tin (ITO) substrates. carried out by immersing an unseeded ITO substrate mixture zinc nitrate hexahydrate (Zn(NO 3 ) 2 ·6H O) and hexamethylenetetramine ((CH 6 N 4 aqueous solution. obta...
