Nanostructure of Materials and Corrosion Resistance

The application of nanotechnology in the field of corrosion protection of metals and alloys attracts the attention of researchers. Many of these applications require good understanding of the corrosion behavior of the materials as a function of microstructure. Significant prog‐ ress has been made in various aspects of synthesis of nano-scale materials. In addition, nanostructures promote select...

Importance of Corrosion Resistance in Dental Materials

For selecting an alloy or material to be used for implant procedure, it is necessary to remember that, there is a number of factors like corrosion behavior, mechanical properties, biocompatibility and cytotoxicity, and also the availability and cost, while the aesthetic measures needed are in a second priority. The most important property is corrosion behavior as it is responsible for the conti...

Strength analysis of seamless double layered fabric using FEM

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...
