Electrostatic Control of Bioactivity

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...

Calcium phosphate films deposited by electrostatic spray deposition and an evaluation of their bioactivity

Tracking and Shape Control of a Micro-cantilever using Electrostatic Actuation

In this paper the problems of state estimation, tracking control and shape control in a micro-cantilever beam with nonlinear electrostatic actuation are investigated. The system’s partial differential equation of motion is converted into a set of ordinary differential equations by projection method. Observabillity of the system is proven and a state estimation system is designed using extended ...

Nanoscale electrostatic control of oxide interfaces.

We develop a robust and versatile platform to define nanostructures at oxide interfaces via patterned top gates. Using LaAlO3/SrTiO3 as a model system, we demonstrate controllable electrostatic confinement of electrons to nanoscale regions in the conducting interface. The excellent gate response, ultralow leakage currents, and long-term stability of these gates allow us to perform a variety of ...

Electrostatic Control of Spontaneous Vesicle Aggregation

Aqueous mixtures of cationic cetyltrimethylammonium p-toluenesulfonate (CTAT) and anionic sodium dodecylbenzenesulfonate (SDBS)spontaneously formequilibrium“catanionic”vesicleswhosechargedepends on the relative amounts of each surfactant. Aggregation of these vesicles was induced by incorporating a small concentration of biotin-lipid in the bilayer, followed by addition of streptavidin as a cro...
