Sarin is now a weapon of the terrorist. Its acute effects are primarily due to unrestricted cholinergic activity at both muscarinic and nicotinic receptors. Treatment is based on the use of large doses of atropine and pralidoxime which may lead to practical problems of sufficient drug supplies for the average hospital. Ventilation may be necessary and present problems. Victim decontamination in...
Abstract A series of natural rubber/butyl rubber NR/IIR blend loaded with N660 carbon black (CB) and triethoxy vinyl silane treated clay nanoparticles (TCNPs) were prepared using gamma irradiation in the presence a polyfunctional monomer, trimethylolpropane triacrylate (TMPTA). The effect incorporating different contents CB five parts per hundred (phr) on mechanical properties nanocomposites ha...
We have developed a technique for cultivation of chemolithoautotrophs under high hydrostatic pressures that is successfully applicable to various types of deep-sea chemolithoautotrophs, including methanogens. It is based on a glass-syringe-sealing liquid medium and gas mixture used in conjunction with a butyl rubber piston and a metallic needle stuck into butyl rubber. By using this technique, ...
Ecological disasters resulting from oil spills have created a great need to find more efficient materials for oil spill cleanup. This research highlights the use of a novel macroporous polymeric material based on butyl rubber (BR) as a sorbent in an oil spill cleanup. The sorption capacity of BR for crude oil and petroleum products is 15-23 g g(-1) as compared to the value of 10-16 g g(-1) obta...
