Properties of Fluorinated Polyimides
This paper reports on two fluorinated polyimides synthesized using a fluorinated diamine, 2,2'-bis(trifluoromethyl) -4,4'-diaminobiphenyl (TFDB). One polyimide, synthesized with TFDB and 2,2'-bis(3,4dicarboxyphenyl)hexafluoropropane (6FDA), has a low dielectric constant, high optical transparency, and a low refractive index. The other, synthesized with TFDB and pyromellitic dianhydride (PMDA), ...
متن کاملChemistry of titanium dry etching in fluorinated and chlorinated gases
native stoichiometric oxide, TiO2, always present on the titanium surface, results in a non-reproducible induction time. During etching the surface of titanium is covered by a highly fluorinated layer which protects the metal by the reaction with oxygen. Chlorine is not able to remove the native oxide unless drastic conditions are realized, Once this layer is removed with fluorine, the reaction...

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 اولrole of cultural iran in promotion of multilaieralism in central asia and caucasus
cultural iran is a scope that is more extended than the political territories of iran as a political unit. this concept means that cultural geography(mehdi moghanlo-1383-1) of iran is greater than its political geography which, according to history, has a long history extending west-east from kandahar to the euphrates and north-south from the persian gulf to the caucasus including transoxiana a...
15 صفحه اولImaging obstructed ventilation with NMR using inert fluorinated gases.
We partially obstructed the left bronchi of rats and imaged an inert insoluble gas, SF(6), in the lungs with NMR using a technique that clearly differentiates obstructed and normal ventilation. When the inhaled fraction of O(2) is high, SF(6) concentrates dramatically in regions of the lung with low ventilation-to-perfusion ratios (VA/Q); therefore, these regions are brighter in an image than w...
