Both of the qualitative and quantitative knowledge of electromagnetic fields in the inter-atomic scale bring useful applications. From this point of view, bringing some possible new sights and solutions to atom-electron-photon-atom and/or molecule interactions is aimed in the near-field at inter atomic scale and their…
The paper provides latest update on the activities performed by the group #4-diodes, shading and reverse bias of the PV Module Quality Assurance Task Force (PVQAT) in the areas such as electrostatic discharge testing and standards, thermal runaway testing, diode junction temperature measurement techniques, thermal end…
The thermo-catalytic decomposition (TCD) of methane has attracted the attention of numerous researchers’ around the world as an ideal approach for hydrogen production, which in turns, can be used as an appropriate feeding gas in fuel cells operating at low temperatures. The TCD of methane is capable to produce a valua…
The importance of partitioning scatterometry data from EUV multilayer mask blanks into amplitude and phase roughness on meeting LWR specifications is examined using thin mask simulations. Scatterometry measurements are unable to determine whether the scattering is due to phase or reflectivity variations. We show that…
Different rotor bars type, lower in iron loss, total loss and thicknesses of steel sheets will increase the efficiency of the induction motor. In this paper, the 3-phase 0.5 Hp AC induction motor have been thoroughly investigated and analyzed in term of efficiency, torque, iron loss, total loss and loss field. The com…
La zeolita es un recurso mineral abundante en el Estado de Sonora, cuya calidad lo convierte en un importante factor corrector de los deteriorados suelos de cultivo del Estado. La agricultura sonorense en los últimos años ha perdido tierras de labor por la salinidad, debido a la escasez de agua y la necesidad de obten…
We study the electronic structure of n-type delta-doped quantum wells in GaAs in which the multiple well system is built according to the Fibonacci sequence. The building blocks A and B correspond to delta-doped wells with impurities densities n2DA and n2DB, and the same well width. The Thomas-Fermi approximation, the…
A mechanically-robust bilayer consisting of a dense polymer base layer that is highly cross-linked and then capped with a covalently-attached thin fluorine-rich top layer reduces the strength of ice adhesion six-fold.

Abstract In situ synthesis of silica gels via a one‐step sol‐gel process at ambient pressure or in supercritical CO2 was investigated. The influence of compressed gas, ultrasound irradiation, and quaternary ammonium salt (choline chloride) on the gelation time was determined. The obtained samples were characterized by…
Aluminum doped zinc oxide (ZnO:Al) layers were exposed to the atmospheric gases carbondioxide (CO2), oxygen (O2), nitrogen (N2) and air as well as liquid H2O purged with these gases, in order to investigate the chemical degradation behavior of these layers. The samples were analyzed by electrical, compositional and op…
In this paper, intrinsic hydrogenated amorphous silicon films are prepared by plasma enhanced chemical vapor deposition. The plasma spectra obtained by an optical emission spectroscopy at different deposition regions are analyzed. By comparing these spectra, the nonuniform deposition regions that could significantly l…
Pharmaceutical wastewater was treated by coupling of micro-electrolysis-catalytic oxidation, using porous multicomponent alloys as packing. Influence of initial pH of wastewater, micro electrolysis time, packing ration, H2O2 dosage and catalytic oxidation time on removal rate of COD in wastewater was studied. The opti…
The unique surface wettability of the silicone rubber can reduce substantially the flashover accidents caused by the dust pollution on the insulator. This paper describes the effects of non-soluble dust, salts component, and natural environment on the surface wettability of the silicone rubber. The structure and compo…
Abstract Several glasses synthesized by sol–gel route and based on the BaO–B2O3–X–Al2O3–SiO2 (X = CaO, MgO) glass system have been investigated to evaluate their applicability as sealant for solid oxide fuel cell (SOFC). Chemical interactions with K41X stainless steel and hydrogen‐tightness of these materials were eva…
To explore the possibility of simultaneously adsorptive treating polluted water containing both organics and heavy metals, multifunctional polymeric resin NDA-1500 was prepared through chemically modification of chloromated polystyrene with salicylic acid. The FT-IR, BET surface area measurements and sodium capacity m…
Diffraction gratings are a promising approach for reducing reflection and achieving light-trapping in solar cells. Using square lattices as a base structure, we investigate a novel bi-periodic nanotub three-dimensional grating structure and compare it with established textured structures for thin-film and wafer applic…
Utilization of the waste toner in wasted print cartridge was beneficial to the environmental protection and resource recycling. Fe3O4 has been obtained from the waste toner via magnetic separation and heat-treatment in present study. XRD measurement revealed the recuperated sample has ferriferrous oxide structure with…
Photo-polymerized polyethylene glycol dimethacrylate (PEGDMA) scaffolds were synthesized using two macromolecular monomers of 750 and 550 number average molecular weight. Variation in chain length of macromolecular monomers visibly influenced viscoelastic properties of the compositions, exhibiting an increase in shear…
The effect of salicylic acid/ethanol as a coupling agent on the tensile properties and thermal stability of recycled high density polyethylene/wood fiber (rHDPE/WF) composites were studied. Both composites rHDPE/WF and rHDPE/WFM (treatment with salicylic acid) were prepared using Brabender Plasticorder at temperature…
