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 اولForced desorption of nanoparticles from an oil-water interface.
While nanoparticle adsorption to fluid interfaces has been studied from a fundamental standpoint and exploited in application, the reverse process, that is, desorption and disassembly, remains relatively unexplored. Here we demonstrate the forced desorption of gold nanoparticles capped with amphiphilic ligands from an oil-water interface. A monolayer of nanoparticles is allowed to spontaneously...
متن کاملThermal Desorption Spectroscopy of Hydrogen from Amorphous Hydrogenated Silicon
T h e r m a l desorption spectroscopy (TDS) based on the mass spectroscopy of thermal ly evolved hydrogen is used for desorption analysis of amorphous hydrogenated silicon (a-Si:H). Two series of glow discharge chemical vapour deposited a-Si:H were investigated by the T D S method . Cons tan t t e m p e r a t u r e growth ra te enabled to determine t empera tu re regions of hydrogen evolution a...
متن کاملZrO2 bubbles from core–shell nanoparticles{
Selective removal of metal cores from core–shell Ag@ZrO2 (ZrO2 coated Ag) and Au@ZrO2 (ZrO2 coated Au) nanoparticles result in stable and freely suspendable oxide nanobubbles of varying dimensions, both in thickness and in diameter. The metal core is removed by a newly found reaction in which halocarbons, generally chlorides, oxidise the metal core and leach out the metal ions. Reduction in the...
متن کاملPreparation of High Surface Area ZrO2 Nanoparticles
In comparison to the previous researches, ZrO2 nanoparticles with higher surface area (85 m2/g) have been synthesized in this research. The as-prepared ZrO2 nanoparticles by co-precipitation method were characterized with X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). The surface area of the s...
