Background: Quantum dots are commonly composed of cadmium contained semiconductors. Cadmium is potentially hazardous but toxicity of such quantum dots is not yet systematically investigated. On the other hand, in vitro studies have shown almost complete control of CdSe induced cytotoxicity by ZnS coverage. Toxicity of CdSe quantum dots and controlling this toxicity by ZnS coverage in immature m...

the aim of the current study was to design a porous osmotic pump–based drug delivery system for controlling the release of buspirone from the delivery system. the osmotic pump was successfully developed using symmetric membrane coating. the core of the tablets was prepared by direct compression technique and coated using dip-coating technique. drug release from the osmotic system was studied us...

We study the statistical properties of the scattering matrix associated with generic quantum graphs. The scattering matrix is the quantum analogue of the classical evolution operator on the graph. For the energy-averaged spectral form factor of the scattering matrix we have recently derived an exact combinatorial expression. It is based on a sum over families of periodic orbits which so far cou...

in this work, we have studied the solvent effects on values of gibbs free energy, enthalpy. entropy and dipolemoment in spread of solvents around anticancer thug of temreolomide that is an alighting agent. for thispurpose, the quantum mechanic calculations bawd on hanrertnick theory at the sto-36/3-2ith levels havebeen done. moreover, we have compared resulted thermodynamic values in gas phase ...

The time evolution of the quantum entropy in a coherently driven threelevel quantum dot (QD) molecule is investigated. The entanglement of quantum dot molecule and its spontaneous emission field is coherently controlled by the gat voltage and the intensity of applied field. It is shown that the degree of entanglement between a three-level quantum dot molecule and its spontaneous emission fields...

In order to implement an integrated optical quantum circuit, designing waveguides based on the quantum box is of prime importance. To do this we have investigated optical waveguide both with and without optical pumping. The rate of absorption and emission using an array of AlGaAs/GaAs quantum box core/shell structure in the optical waveguide with various pumping intensities has computed. By con...
