Separation of oxygen by cold

Separation by Plasma Implantation of Oxygen (SPIMOX) Operational Phase Space

Separation by plasma implantation of oxygen (SPIMOX) has been suggested as an economic alternative for separation by implantation of oxygen (SIMOX) to form the silicon-oninsulator (SOI) structure. The chief advantage of SPIMOX is the high throughput and low-cost implanter. The operation regime of implantation for SPIMOX, which uses dc plasma immersion ion implantation (PIII) for the oxygen impl...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Oxygen Poisoning in Cold Blooded Animals

1. Exposure of frogs to atmospheres containing approximately 95 per cent of oxygen is without apparent effect on their state of well being, and produces no noticeable changes in the appearance of their web capillaries. 2. Turtles exposed to similar atmospheres are also apparently unaffected unless the oxygen be warmed to mammalian temperature. 3. At this temperature (37.5 degrees C.) the turtle...
