With the growing attention drawn to the electrical substation electromagnetic environmental problem, the application of material with electromagnetic shielding effect gains more and more popularity. This work evaluated the electromagnetic shielding effect of aluminum foam in 10 kV Xifaxian transformer dado and three e…
In this work, the effects of the bimodal particle size distribution of fused silica on the properties of silica-based ceramic cores have been investigated. In order to simulate a casting process condition, the core specimens were sintered at 1220°C, tested at above 1500°C. Three point bending tests were carried out on…
In this study, the semiconducting single-walled carbon nanotube (semi-SWCNT) thin film transistors (TFTs) with high dielectric constant (κ) atomic layer deposited ZrAlOx gate insulator are fabricated by the drop-casted method. The hysteresis characteristic, negative gate voltage stress stability, and thermal stability…
Purpose. The work is aimed to identify the reasons for the significantly higher coefficient of the empty weight of 1520 mm gauge cars in comparison with the freight cars in North America and to give recommendations for reducing the empty weight of freight cars. Methodology. As a methodology, a comparative evaluation o…
Abstract In this work, we report on the production of regular (SiGe/SiO 2 ) 20 multilayer structures by conventional RF-magnetron sputtering, at 350 °C. Transmission electron microscopy, scanning transmission electron microscopy, raman spectroscopy, and x-ray reflectometry measurements revealed that annealing at a tem…
Superhydrophobic coatings are a relatively new class of coatings with a variety of applications. But their application is constrained by two main drawbacks. The first is complexity and high cost of production methods. The second is low mechanical resistance of coatings.The work used a single-stage production method, w…
Polyethylene terephthalate (PET) fiber is applied to clothing, home textiles and other fields because of its low cost, high strength, quick-drying and stable structure, etc. Polyester fiber generally doesn’t have the ability to kill bacteria, and it is a kind of porous material which is conducive to the microbial adhe…
Thermally resistant polyurethane foams containing 1,3,5-triazine ring were modified with additive flame retardants. It has been found that addition of melamine, melamine polyphosphate, or isocyanurate at the foaming step resulted in reduction of foam flammability. The physical properties of flame-retardant modified fo…
Although research into the tissue engineering of vessels has proceeded at a tremendous pace, many deficiencies still need to be resolved. A well-adopted constructed vessel requires both functional and structural properties to stimulate the native vessel and resist stress and tension in vivo. In the present study, we d…
We demonstrate permanent water trapping in reduced graphene oxide after high relative humidity exposure. For this purpose, we grew graphene oxide films via spin-coating on glass substrates followed by thermal reduction. The electrical resistance of the planar device was then measured. We observed that resistance is si…
Abstract The electrochemical performance of supercapacitors might be associated with the homogeneous structure of the electrode materials. However, the relationship between the degree of uniformity for the electrode materials and the electrochemical performance of the supercapacitor is not clear. Herein, we synthesize…
Mesoporous materials with large surface area and chemical inertness are of great importance, and currently prevailing synthetic approaches involve usages of micelles as pore-directing agents to create such mesopores. In this work, allophanes, which are hollow aluminosilicate spherules of 3.5–5.5 nm in size, have been…
This study investigated the chemical grafting of a single-layer poly(vinyl alcohol) (PVOH) film. The effect of the grafting parameters (grafting time, grafting temperature, and concentration of fatty acid chloride) on the hydrophobicity of the film surface and the film solubility were evaluated. The PVOH substrate fil…
The substrate specificity of enzymes is crucial to control the fate of metabolites to different pathways. However, there is growing evidence that many enzymes can catalyze alternative reactions. This promiscuous behavior has important implications in protein evolution and the acquisition of new functions. The question…
The properties of Al-doped ZnO (AZO) films are known to degrade with exposure to humidity. Different AZO films deposited using reactive direct current magnetron sputtering (DCMS) and high power impulse magnetron sputtering (HiPIMS) have been aged in ambient laboratory conditions and annealed at temperatures between 16…
High Resolution Image Download MS PowerPoint Slide In this article, we describe the deposition by aerosol-assisted spray pyrolysis of different types of silver vanadate nanocomposites with and without graphene oxide (GO) on different substrates (carbon paper (CP) and fluorine-doped tin oxide (FTO)). When deposited on…
Abstract Various zinc oxide (ZnO) nanostructures are widely used for photocatalytic antibacterial applications. Since ZnO possesses a wide bandgap, it is believed that only UV light may efficiently assist bacterial inactivation, and diverse crystal lattice modifications should be applied in order to narrow the bandgap…
A series of carbon-based materials were illustrated to be efficient additives to improve the product distribution of isobutane/butene alkylation catalyzed by H 2 SO 4 . Among the tested materials, graphene oxide (GO) was shown to be the most efficient additive. With the presence of trace amounts (e.g., 0.1 wt %) of GO…
The main objective of this study was to prepare polyurethane foam reinforced with local Turkish natural resources. In this work, olive kernel and nutshell fibers were used for reinforcing the polyurethane foam. In order to characterize reinforced polyurethane samples, mechanical, chemical, thermal, and morphological m…
We report the electrochromic properties of a polymeric nanocomposite prepared by potentiodynamic deposition of transition-metal complex [Ni(3-Mesalen)], designated as [1], in the presence of TiO 2 nanoparticles (NPs) with an average size of 9.7 ± 1.1 nm. Entrapment of TiO 2 NPs in the poly[1] matrix was confirmed by s…
