Reactive Al-O-Al sites natural zeolite Triple-quantum oxygen-17 nuclear magnetic resonance
2012/4/1
In framework aluminosilicate materials (e.g., feldspars, zeolites and many others), it is generallyassumed that AlOtetrahedra do not share corners, i.e., that Al-O-Al oxygen sites are avoided whenstoi...
Effects of a Snake Venom and Some Hypometabolic Agents on the Substandard Gas-Oxygen Metabolism in Mice
Gas-oxygen metabolism snake venom intoxication Mus
2010/4/1
A lethal dose of the snake Vipera lebetina venom decreases the standard gas-oxygen metabolism of mice approximately threefold while its nonlethal dose does so twofold. The same effects on the gas-oxyg...
