Growth of Boehmite Nanofibers by Assembling Nanoparticles with Surfactant Micelles

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...

Synthesis of CdS nanoparticles in switchable surfactant reverse micelles.

A facile method for synthesis of CdS nanoparticles has been described. Monodisperse face-centered cubic CdS NPs could be synthesized in switchable surfactant reverse micelles. The micelles could be broken easily and CdS NPs without a coating of surfactants could be obtained by bubbling N(2) at 65 °C.

Effect of surfactant treated boehmite nanoparticles on properties of block copolymers

The effectiveness of reinforcement of a polymer is known to depend on the strength of the interfaces between the reinforcement and the matrix. We have used polystyrene and a styrene– butadiene–styrene (SBS) copolymer as matrixes and ceramic boehmite c-AlO(OH) as reinforcement. We have applied boehmite both untreated and treated with sulphonic acid based surfactants with different alkyl groups. ...

Rhodium nanoparticles entrapped in boehmite nanofibers: recyclable catalyst for arene hydrogenation under mild conditions.

A new recyclable rhodium catalyst was synthesized by a simple procedure from readily available reagents, which showed high activities in the hydrogenation of various arenes under 1 atm H2 at room temperature.
