investigation of the electronic properties of carbon and iii-v nanotubes

boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...

Partial . Purification and Some Properties

Two polyphenoloxidases (PPO ] and PPO III, EC 1,10.3,1) were extracted and partially purified from sago palm pith by hydroxylapatite chromatography, DEAE-cellulose chromategraphy and gel filtration. Both purified isozymes gave a single activity band on polyacrylamide gel electrophoresis. The rno]ecular weights of both enzymes were estimated to be 40,OOO. Thev had the same pH optima of 6,5 but ...

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...

Partial purification and properties of renal glutaminase.

In 1935, Krebs (1) suggested that there may be several glutaminases. A useful preparation of renal ‘Lglutaminase” was described by Archibald (2) ; Greenstein and Carter (3) demonstrated the existence of two types of glutaminases which were activated by a-keto acids and phosphate, respectively. The mechanism of the a-keto acid-activated glutaminases has been demonstrated by Meister and Tice (4),...
