Behavior of Three Types of Plasma Sources for Optical Coating
Typical plasma sources, as used in optical coating, bombard the surfaces of the substrates with electrons and ionized gasses such as argon, oxygen, and nitrogen. The energy of the ions in electron volts and the ion current depend primarily on the source geometry, gas flow, pumping speed of the chamber, and the current provided by the power supplies to the ion source and electron source. Three c...
متن کاملCompaction Properties of Three Types of Starch
A study has been made of the compaction properties of two experimental starches, namely yam starch obtained from Dioscorea rotundata and rice starch obtained from Oryza sativa and the mechanical properties of their tablets, in comparison with those of official corn starch. The influences of the physical and geometric properties of the starch particles on the compression properties of the starch...

متن کاملmicroleakage of three types of glass ionomer cement restorations: effect of cpp-acp paste tooth pretreatment
statement of the problem: casein phosphopeptide–amorphous calcium phosphate (cpp-acp) increases the mineral content of tooth structure. this may enhance the chemical bonding of glass ionomer cements (gic) and marginal sealing of their restorations. purpose: the aim of this study was to evaluate the effect of cpp-acp paste pretreatment on the microleakage of three types of gic. materials and met...
متن کاملcontrol 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...
