This research presented the surface oxidation of stainless steel grade 304 (S304) welded by a gas tungsten arc welding (GTAW) process. The welded S304 was inspected by visual and penetrant testing methods. The surface of the welded specimen was oxidized by the chromic solution to an obtained oxide film on S304 welded…
In this research, jute fiber reinforced polypropylene and poly (lactic acid) composites were fabricated, respectively by Direct Fiber Feeding Injection molding (DFFIM) process. Jute spun yarns were directly fed into the barrel of molding process in order to eliminate the fiber breakage during extrusion compounding pro…
Barkhausen noise (BHN) is a technique that can be used to evaluate properties of ferromagnetic materials; case depth, coating depth, residual stress, grinding burnt damage, and hardness of a metallic material. The commercial BHN measuring devices commonly used are relatively expensive. Therefore, the steel industries…
The effect of Cephalexin monohydrate drug on the corrosion performance of low carbon steel (LCS) in 1 M HCl solution has been examined by weight reduction (WR), potentiodynamic polarization (PP) and AC impedance spectroscopy (EIS) tests. The inhibition efficiency (IE) raised with increasing the cephalexin monohydrate…
Chemical reactions that exhibit self-sustained oscillations show great promise for designing multifunctional materials for biomimetic applications. Belousov–Zhabotinsky (BZ) reactions are dynamical systems that operate far from equilibrium and thus serve as model systems for such applications. Catalyzed by a metal ion…
Representative pathogenic bacteria such as Escherichia coli ( E. coli) and Staphylococcus aureus ( S. aureus) are widespread in nature and pose a threat to human health. To control the propagation of these pathogens from the source, the key is to design broad-spectrum antibacterial materials to reduce the serious dama…
Reverse spherification is a common technique used in molecular gastronomy to produce innovative products with an improved texture by shaping a liquid into an edible semisolid sphere that gives a burst in the mouth sensation. In this study, liquid-core hydrogel beads (LHBs) were prepared using Syzygium caryophyllatum f…
Production of particles and their adaptation in the pharmacology became an object of interest, and they are the currently introduced therapies based on the use of micro and nanoparticles. The use of gold particles is not an exception. This review has focused on the application of gold micro and nanoparticles in pharma…
Polymer brushes are widely used to modify the physico-chemical properties of surfaces. By introducing chains with adsorption-active end groups to a brush, the properties of a surface can be altered by external stimuli, enabling the functionalized ends to be switched between the exposed and the adsorbed, hidden state.…
Abstract The enhancement of triplet–triplet annihilation upconversion (TTA-UC) processes is of profound significance to address key bottleneck problem associated with the practical applications of TTA-UC. In this work, optimized multibandgaps photonic crystal (PC) structures were introduced to dramatically amplify the…
Impulse corona characteristics are very important for the analysis of overvoltage along overhead transmission lines. For DC line, the space charge due to normal corona may affect the impulse corona characteristics. The paper develops a circuit for combined application of DC and impulse voltage to measure the effect of…
Infrared-active lattice mode properties of melt-grown high-quality single bulk crystals of ZnGa2O4 are investigated by combined spectroscopic ellipsometry and density functional theory computation analysis. The normal spinel structure crystals are measured by spectroscopic ellipsometry at room temperature in the range…
The evaluation of toxic effects of nanoparticles (NPs) has become an important aspect of Nanotechnology research in the 21st century. The present investigation deals with the green synthesis of biogenic zinc oxide nanoparticles (ZnO-NPs) using Bryophyllum pinnatum leaves, their characterization and evaluation of acute…
Abstract In this study, Paraloid B‐72 (poly methyl methacrlylate/ethylacrylate 70:30) and its nanocomposites with titanium dioxide (TiO2) concentration 1–5% have been prepared by emulsion polymerization technique and characterized by transmission electron microscope (TEM), Fourier‐transform infrared spectroscopy (FT‐I…
It was recently discovered that a conductive, metallic state is formed on the surface of some insulating oxides. First observed on ${\mathrm{SrTiO}}_{3}$ (001), it was then found in other compounds as diverse as anatase ${\mathrm{TiO}}_{2}$, ${\mathrm{KTaO}}_{3}$, ${\mathrm{BaTiO}}_{3}$, ZnO, and also on different sur…
We study the Brownian motion of ellipsoidal particles lying on an agitated granular bath composed of magnetic particles. We quantify the mobility of different floating ellipsoidal particles using the mean-square displacement and the mean-square angular displacement, and relate the diffusion coefficients to the bath pa…
The EU's End of Life Vehicles (ELV) regulations are forcing car manufacturers to consider the environmental impact of their production and possibly shift from the use of synthetic materials to the use of agro-based materials. However, poor mechanical properties and certain manufacturing limitations currently limit the…
Purpose The purpose of this paper is to evaluate the efficiency of commercial silica, silica fume-waste (SF) and modified silica fume-waste (mSF) as reinforcing filler in acrylonitrile-butadiene rubber (NBR) and ethylene propylene diene monomer (EPDM) through the mixing process of rubber. The composites were prepared…
A series of triads consisting of a triarylamine donor, a naphthalenediimide acceptor, and a palladium photosensitizer bridge was investigated for the photoinduced electron transfer processes and the spin chemistry involved. In this series, the ligand in the palladium photosensitizer was varied from bis-dipyrrinato to…
Glass compositions 42 P2O5–40ZnO–(18-x)Na2O: xNiO in which x varies from 0 to 6 mol.% with step of 1 mol.%, are prepared by using the conventional melt annealing method. The effect of nickel ions in the investigated glass system appears in the combined structural and optical properties. Some structural and optical par…
