Abstract Advanced structures of oxide TFT have been studied for various display applications. Oxide TFT with etch‐stopped layer has shown excellent uniformity and stability for display products. For mass production with low cost, however, back channel etched structure with/without titanium etch‐stopped one has been st…
Tension tests were carried out to investigate the effect of the corrosion pattern on the ductility of tension bars extracted from a 26-year-old corroded reinforced concrete beam. The tensile behavior of corroded bars with different corrosion patterns was examined carefully, as were two non-corroded bars extracted from…
Over the last decade, there have been significant advancements in the material synthesis and processing aspects of the carbon nanotube (CNT) technology, and the basic understanding of its multifunctional properties. Lockheed Martin Space Systems has been evaluating CNTs, vapor-grown carbon nanofibers (VGCF), and CNT s…
Abstract Alginate-SBA-15 (ALG-SBA-15) was synthesized by encapsulation of the nanoporous SBA-15 in the biopolymeric matrix of calcium alginate. This adsorbent was characterized using powder X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), nitrogen adsorption-desorption and Fourier transform infrared (FT-IR…
It has been experimentally shown that water vapor thermal treatment of silicate glasses with silver ions introduced by ion exchange leads to the formation of a silver nanoparticle layer with a high packing density on the glass surface. The results of studying the morphology of samples by atomic force and electron micr…
Abstract Anisotropic magnetoresistance (AMR) is an important physical phenomenon that has broad application potential in many relevant fields. Thus, AMR is one of the most attractive research directions in material science to date. In this article, we summarize the recent advances in AMR, including traditional permall…
The asset management of any Transmission System Operator (TSO) cannot ignore the evaluation of the power transformers fleet. Even in the absence, to date , of any specific international guide or standard, every big electrical utility is adopting a home-made “Health Index”. An RI is developed to summarize in numerical…
The novel isotropic pitch that exhibits both high solvent solubility (100% soluble in THF) and a high softening point (over 200°C) was successfully synthesized by the bromination of 2-methylnaphthalene followed by dehydrobromination/polymerization and extraction in n-hexane to eliminate lighter constituents. The molec…
The theory of an exciton with a spatially separated electron and hole (the hole is in the quantum dot volume, and the electron is localized at the outer spherical quantum dot-dielectric matrix interface) is developed within the modified effective mass method. The effect of significantly increasing the exciton-binding…
Type systems for information-flow control (IFC) are often inflexible and too conservative. On the other hand, dynamic run-time monitoring of information flow is flexible and permissive but it is difficult to guarantee robust behavior of a program. Gradual typing for IFC enables the programmer to choose between permiss…
Successive applications of pig slurry and pig deep litter may lead to an accumulation of copper (Cu) and zinc (Zn) fractions in the soil profile. The objective of this study was to evaluate the Cu and Zn forms and accumulation in a Sandy Typic Hapludalf soil after long-term application of pig slurry and deep litter. I…
BACKGROUND: Pseudomonas aeruginosa represents a good model of antibiotic resistance. These organisms have an outer membrane with a low level of permeability to drugs that is often combined with multidrug efflux pumps, enzymatic inactivation of the drug, or alteration of its molecular target. The acute and growing prob…
The effect of set-back distance on the thermo-mechanical behavior of the strip during twin roll casting (TRC) of an AZ31 magnesium alloy was modeled using finite element method (FEM). Model validation was done by comparing the predicted and measured exit strip surface temperature as well as the secondary dendrite arm…
Abstract This paper presents the development of a mix design method for geopolymer mortar mixes with a principal focus on compressive strength. The method is based on the hypothesis that the overall strength of geopolymer mortar depends on the strength of the geopolymer binder materials, the packing density of the agg…
The survival of important pieces of our architectural and sculptural heritage is challenged by irreparable damage due to crystallization of soluble salts. Mineral precipitation is also a problem in many industrial processes, leading to costly scale formation. Most of the mechanisms that control these crystallization r…
Abstract Solution thermodynamic studies were performed to characterize the coordination of U(VI) and Th(IV) by the multidentate hydroxypyridinonate chelating agents 3,4,3-LI(1,2-HOPO) and 5-LIO(Me-3,2-HOPO). Species distribution and conditional stability pM profiles were calculated based on the determined formation co…
The widespread application of nanomaterials (NMs), which has accompanied advances in nanotechnology, has increased their chances of entering an organism, for example, via the respiratory system, skin absorption or intravenous injection. Although accumulating experimental evidence has indicated the important role of NM…
This study aimed to develop hydrophilic matrix based controlled release gastroretentive drug delivery system of ofloxacin and conducting its in vitro and in vivo evaluations. Effervescent floating gastroretentive drug delivery system of ofloxacin was prepared utilizing Box–Behnken statistical design with 3 factors, 3…
We have been focused on improving conversion efficiency of Cu(In, Ga)(Se, S)2(CIS)-based solar cell with 30×30cm2-sized submodules, and achieved an efficiency of 17.8% up to now[1]. In this report, we will present an achievement of certified 19.7% conversion efficiency with a small-sized single cell (approximately 0.5…
BACKGROUND: Iron oxide nanoparticles (IONPs) can attenuate oxidative stress in a neutral pH environment in vitro. In combination with an external electromagnetic field, they can also facilitate axon regeneration. The present study demonstrates the in vivo potential of IONPs to recover functional deficits in rats with…
