Physics of Outgassing
This paper relates the physical bases of the gassing phenomena in ultra-high vacuum. The main phenomena discussed are: diffusion of gases through system walls and solids in vacuum, solubility of gases on solids and permeation as well as the phenomena of adsorption, desorption and absorption.

کاتالیست یک سنتز جدید برای تیواترها توصیف شده است. واکنش الکل ها با آریل، هتروآریل و آلکیل تیو ل ها درحضور 1،3،5- تری آزو- 2،4،6- تری فسفرین-2،2،4،4،6،6 هگزاکلراید ((tapc به عنوان یک کاتالیست موُثر، بازده های خوب تا عالی از تیواترها را حاصل می کند. علاوه براین، واکنش تحت شرایط بدون فلز و بدون حلال پیش می رود، بنابراین یک مکمل جالب برای روش های شناخته شده سنتز تیواترها ارائه می دهد. یک مکانیسم ا...
15 صفحه اولIntermittent outgassing through a non-Newtonian fluid.
We report an experimental study of the intermittent dynamics of a gas flowing through a column of a non-Newtonian fluid. In a given range of the imposed constant flow rate, the system spontaneously alternates between two regimes: bubbles emitted at the bottom either rise independently one from the other or merge to create a winding flue which then connects the bottom air entrance to the free su...
