Physical Adsorption of Mixed Gases at Very Low Pressures

Transmission of Sound Waves in Gases at Low Pressures

Midway through World War II it became apparent that a better understanding of the motion and interaction of gaseous media with solid objects was needed. As aircraft flew at higher altitudes, approaching the speed of sound, strange shock wave effects interrupted normal flight. Propulsion mechanisms became challenged by the rapid increases in frictional drag. At the same time, the fledgling nucle...

Adsorption at High Pressures

Physical adsorption between mono and diatomic gases inside of Carbon nanotube with respect to potential energy

In this paper we have down three theoretical study by using Monte Carlo simulation and Mm+,AMBER and OPLS force field. The calculations were carried out using Hyper Chem professional,release 7.01 package of program. first we have studied the interaction of H2 molecule and He atomwith single-walled carbon nanotube at different temperature. For doing this study we placed H2 andHe in the center an...

Regeneration of СO2 Physical Solvents at Elevated Pressures in Gas-Liquid Membrane Contactor

In the present work, a membrane contactor with asymmetric flat-sheet poly(vinyltrimethylsilane) (PVTMS) membranes was proposed for the CO2 desorption process from physical solvents at elevated trans-membrane pressures. Different solvents were studied: water, a mixture of polyethylene g...

The Rate of Decomposition of Nitrogen Pentoxide at Very Low Pressures.

(3) The reaction time of the direct growth-response is constant for a particular intensity of illumination, provided that the duration of the exposure period exceeds a certain value. Below that value the reaction time increases as the exposure time decreases. This is also true for the phototropic response. (4) The manner in which the reaction time of each mode of response varies as a function o...
