ZnO particles with an average size of about 5 nm were prepared via a sol-gel chemical route and the silane coupling agent, (3-glycidyloxypropyl)-trimethoxysilane (GPTS), was adopted to enhance the dispersion of the ZnO nanoparticles in ethyl glycol (EG) solution. A ZnO surface potential as high as 66 mV was observed and a sedimentation test showed that the ZnO precursor solution remains transpa...

The electron-electron relaxation in impure two-dimensional superconductors is studied. All channels of the electron-electron interaction classified in the Nambu representation are taken into account. It is shown that the recombination relaxation rate originates from quasipartical processes associated with fluctuations of the electron density and the phase of the order parameter. At low temperat...

Angular dependence of x-ray fluorescence techniques have been employed to investigate the effects of thermal annealing at various temperatures ranging from 340 to 387 °C on a series of CdTe/CdS heterojunctions. Changes in depth profiles of Te and Cd atoms in the CdS layer as a result of heat treatment has been observed. A simple model is proposed for comparison of the ratio of Te Ka to Cd Ka fl...

The Li2TiO3-coated LiNi0.5Co0.2Mn0.3O2 (LTO@NCM) cathode materials are synthesized via an in situ co-precipitation method followed by the lithiation process and thermal annealing. The Li2TiO3 coating layer is designed to strongly adhere to the core-material with 3D diffusion pathways for Li(+) ions. Electrochemical tests suggest that compared with pristine NCM, Li2TiO3 serves as both a Li ion c...

We derive and evaluate expressions for the frictional Coulomb drag between disordered two-dimensional electron gas layers. Our derivation is based on the memory-function formalism and the expression for the drag reduces to previously known results in the ballistic limit. We find that Coulomb drag is appreciably enhanced by disorder at low temperatures when the mean-free-path within a layer is c...

Background and purpose: Because of the importance of early diagnosis of cervical cancer and high false negative results of conventional smear method, several studies have been performed to find a more appropriate test in recent years. Fluid-based methods especially thin prep are considered to have the highest potential to reduce the false negative results and to increase the adequacy of speci...

mixing height of the atmospheric boundary depends on the vertical variation of temperature in the atmosphere which includes temperature inversion (including surface and elevated inversions) that has a significant effect on air quality. the mixing height like some other meteorological variables has diurnal variations. the reason for that is its dependence on some other basic meteorological param...

Multilayered polymer films with biomimicking, layered structures have unique microstructures and many potential applications. However, a major limitation of polymer films is the deterioration of mechanical properties in working environments. To facilitate the design and development of multilayered polymer films, the impact of thermal aging on the mechanical behavior of microand nano-layered pol...
