In this work we present the yield ratios of the 179m,g^{179m,g}W isomeric pair produced in the photonuclear reactions nat^{nat}W(g,xn)179m,g^{179m,g}W with bremsstrahlung end-point energies of 50-, 55-, 60-, and 65-MeV. The measurements were ca... see more

The natural radioactivity due to presence of 226Ra, 232Th and 40K radionuclides in Lao PDR cements was measured for first time using a gamma-spectrometry with HPGe detector. Two different types of cement produced by 4 local cement companies in Lao PDR hav... see more

We investigate the edge e?ects of the optical analogue of the quantum relativistic Dirac solitons in binary waveguide arrays with Kerr nonlinearity when one tail of the Dirac soliton is truncated. We show that if the outermost waveguide of the binary wave... see more

We studied population distribution of vibrational levels for the 21?^1\Pi of NaLi molecule from v'=0v'=0 to v'=16v'=16. The population of the levels was calculated numerically by solving the radial Schrodinger equation with an experimental poten... see more

Platinum (Pt) electrodes were designed in imitation of screen-printed electrodes, and prepared by microelectronic techniques. These electrodes were then modified with zinc oxide (ZnO) nanofibers for biosensing applications. ZnO nanofibers w... see more

Ag–TiO2 thin film was fabricated by DC magnetron sputtering and photoreduction methods. Characteristics of the film such as surface area, crystal structure, and chemical composition were investigated by using scanning electron microscope (SEM), X–ray diff... see more

NiPt alloys were prepared successfully by galvanic replacement reaction on the surface of Ni films. The electrolytic deposition of Ni films was investigated to get the high qualities of Ni films for the galvanic reaction. The influence of the electrolytic... see more

We investigate the relaxation rate and mobility of a two-dimensional electron gas (2DEG) confined in MgZnO/ZnO heterostructures (HSs) for temperatures , taking into account exchange and correlation effects. We use the variational-subband-wave-function mod... see more
