Bustling argon: biological effect
Argon is a noble gas in group 18 of the periodic table. Certificated to exist in air atmosphere merely one century ago, discovery of argon shows interesting stories of researching and exploring. It was assumed to have no chemical activity. However, argon indeed present its biological effect on mammals. Narcotic effect of argon in diving operation and neur-protective function of argon in cerebra...
متن کاملEffect of argon protection on the biological activity of acid etched titanium surface.
OBJECTIVE As the contamination of implant surface seriously affects the early osseointegration of implants and reduces the survival rate of implants, it has attracted wide attention of researchers. The most oral titanium implants used in current clinical applications are stored in sealed packages. During the process of packaging, storage and usage, the implants inevitably contact air, which res...
متن کاملThermodynamic Properties for Argon
An analytical equation of state is applied to calculate the thermodynamic properties for argon. Theequation of state is that of Song and Mason. It is based on a statistical-mechanical perturbation theory ofhard convex bodies and can be written as fifth-order polynomial in the density. There exist three temperaturedependentparameters: the second virial coefficient, an effective molecular volume,...
متن کاملArgon neuroprotection
Certain noble gases, though inert, exhibit remarkable biological properties. Notably, xenon and argon provide neuroprotection in animal models of central nervous system injury. In the previous issue of Critical Care, Loetscher and colleagues provided further evidence that argon may have therapeutic properties for neuronal toxicity by demonstrating protection against both traumatic and oxygen-gl...
