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...
15 صفحه اولOptical Calibration of a Submicrometer Magnification Standard
The calibration of a new submicrometer magnification standard for electron microscopes is described. The new standard is based on the width of a thin thermal-oxide film sandwiched between a silicon single-crystal substrate and a polysilicon capping layer. The calibration is based on an ellipsometric measurement of the oxide thickness before the polysilicon layer is deposited on the oxide. The u...
متن کاملOptical magnification for subnormal vision: historical survey.
Early attempts to provide optical magnification to compensate for subnormal visual acuity used small galilean telescopes, mounted in spectacle frames, giving magnifications ranging from 1.3 to 3 ~ . They were seldom helpful in distance vision because of the restricted field, change of apparent distance, and inadequate magnification. Many used them only for reading, and obtained additional magni...

متن کاملModified Excipients in Novel Drug Delivery: Need of the Day
Drug products not only contain “actives” that confer the intended therapeutic benefits such as pain relief or act on particular part of the body, but contain other materials that are also “functional” with respect to the drug product. These are known as excipients and specific functionality which they confer to a particular product is independent upon the process used to add the excipient to th...
