We calculate the exciton radiative lifetime of spherical Indium Phosphide (InP) and Cadmium Selenide (CdSe) colloidal quantum dots. In experiments, InP and CdSe quantum dots can be coated by another semiconductor shell, organic ligands, or inorganic molecules.

The elastic constants and various optical properties of MnIn2S4 including the dielectric constant, absorption coefficient, electron energy loss function and reflectivity were calculated as a function of incident photon energy. Those results are discussed in this study and compared with available experimental results.

We have investigated the thermodynamic properties of the cubic zirconia ZrO2 using the statistical moment method in the statistical physics. The free energy, thermal lattice expansion coefficient, specific heats at the constant volume and those at the constant pressure, CV and CP , are derived in closed analytic forms in terms of the power moments of the atomic displacements.

The structure of the complex between the minor groove binder netropsin and d(GGCCAATTGG) was determined via single-crystal X-ray tech-niques. The structure was refined to completion usingrefmac5.1.24, result-ing in a residual R-factor of 20.0% (including 68 water molecules). Using crystal engineering and cryocooling techniques, the resolution could be enhanced to 1.75 A ˚ , resulting in an unambiguous determination of the drug conformation and orientation.
