Electronic and Optical Properties of Rocksalt MgZnO and Wurtzite ZnMgO with Varied Concentrations of Magnesium and Zinc.

The structural, electronic and optical properties of rocksalt Mg1-xZnxO and wurtzite Zn1-xMgxO with the concentration of Zn and Mg varying from 0.125 to 0.875 were investigated using density functional theory (DFT), DFT+U, linear response theory and the Bethe-Salpeter equation.

Current development and patents on high-brightness white LED for illumination.

In this paper, we reviewed the current development and patents for the application of high-brightness and high-efficiency white light-emitting diode (LED). The high-efficiency GaN nanostructures, such as disk, pyramid, and rod were grown on LiAlO(2) substrate by plasma-assisted molecular-beam epitaxy, and a model was developed to demonstrate the growth of the GaN nanostructures. Based on the results, the GaN disk p-n junction was designed for the application of high brightness and high efficiency white LED.

Effects of glycolic acid on the induction of apoptosis via caspase-3 activation in human leukemia cell line (HL-60).

Apoptosis is a particular process that leads to the programmed cell death, and it has been a potentially therapeutic target of cancer. In this study, we evaluated the possible apoptotic effects of glycolic acid on human leukemia cell line (HL-60) in vitro. The morphological changes, cell viability, apoptosis induction, and caspase-3 activity were measured by phase microscopy, flow cytometry, and Western blot analysis.
