Our study is based on the synthesis and the application of the membrane prepared from treated /non treated clay and starch at different volumes and concentrations. The best membranes found has been tested for their abilities ...

The primary goal of our works is the calculation method of simulating a gas separation (rectification). tray by tray method allows us to control all parameters affecting influencing the process such as temperature, pressure ...

A part of the Algerian natural gas is destinated to the exportation, where it should be liquefied is a necessity; this last operation is possible except if we eliminate the CO2 which the natural gas contains. The reduction ...

A simple technique (solvent phase inversion) has been used to prepare biodegradable polymeric membranes based on a mixture of clay (chemical treated, no treated) and starch. The disc samples of 100-300μm thickness were ...

The objective of this work is to establish a program that determines the electron trajectories and backscattered electrons in a solid material bombed by an electron beam and using the statistical Monte Carlo method. From ...

The work presented in the context of this thesis concerns the determination of the distribution of electron density of compound chemical formula C8H9NOS from a spectrum of high-resolution X-ray diffraction on single crystal ...
