here, we report analysis of in vitro and in vivo drug release from an in situ formulation consisting of triamcinolone acetonide (tr) and poly(d,l-lactide-co-glycolide) (plga) and the additives glycofurol and hydroxyapatite nanoparticles (ha). we found that these additives enhanced drug release rate. we used the taguchi method to predict optimum formulation variables to minimise the initial burs...
Stable gold cluster molecules of the type Au11, [1a] Au13, [1b,c] and Au55, [1d] have been fascinating and were some of the early molecular nanosystems synthesized. Quantum phenomena such as Coulomb blockade were demonstrated with them. Unusually intense luminescence and chemical reactivity of molecular clusters or quantum clusters (QCs) of noble metals, for example gold have attracted intense ...
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...
