Hydrogen evolution reaction is inevitable during the corrosion of Mg alloys. The effect of hydrogen on the corrosion behavior of the Mg–2Zn and Mg–5Zn alloys is investigated by charging hydrogen treatment. The surface morphologies of the samples after charging hydrogen were observed using a scanning electron microscop…
The modelling of the dynamic behavior of hysteretic materials and devices must take into account magnetodynamic effects. In the present paper these tasks are simultaneously modelled by means of an ad-hoc Neural System (NS) based on an array of 3-input 1-output Feed Forward NNs. Each NN is aimed to a particular typolog…
We prepared Bi 6 Fe 2 Ti 3 O 18 thin films on Pt/Ti/SiO 2 /Si substrates with thickness ranging from ∼300 to ∼900 nm by using a chemical solution deposition route and investigated the thickness effects on the microstructure, dielectric, leakage, and ferroelectric properties of Bi 6 Fe 2 Ti 3 O 18 thin films. Increasin…
This paper presents development of a flexible thermoelectric energy harvester by using transfer printed doped Silicon (Si) microwires. The thermoelectric generator (TEG) module, consisting of an array of 34 alternately doped p-type and n-type Si microwires, is developed on a Si on insulator (SOI) wafer using standard…
To explore the possibility of reuse olive pomace extract as a corrosion inhibition of steel in an acidic medium (HCL, 1 mol/L), and to compare the inhibitory effect of olive pomace (OP) samples collected from three extraction process of olive oil: press process, continuous process three-phase and continuous process tw…
The corrosion of copper -nickel alloy in hydrochloric acid was investigated at different temperatures, inhibitor concentrations, and corrosive solution rotation rates. Weight loss technique was used to evaluate the corrosion rate data. Tetraethylenepentamine was used as organic corrosion inhibitor, while hydrochloric…
Colloidal CdSe semiconductor nanoplatelets with characteristic longitudinal sizes of 20–70 nm and thicknesses of several atomic layers are synthesized. The spectra and kinetics of the photoluminescence of these quasi-two-dimensional nanostructures (quantum wells) at room and cryogenic temperatures are investigated. A…
The present study investigated the effect of anodization time on the anodic oxide films formed on titanium alloy Ti-6Al-2Zr-1Mo-1V. The morphology, surface roughness, crystal structure, and electrochemical impedance of the anodic oxide films were studied by using scanning electron microscopy (SEM), atomic force micros…
An accurate X-ray diffraction study of a Nd 3 Ga 5 SiO 14 crystal (sp. gr. P 321, Z = 1) has been performed using repeated X-ray diffraction data sets collected on a diffractometer equipped with a CCD area detector at 295 and 90 K. The asymmetry of the disorder in the atomic positions in Nd 3 Ga 5 SiO 14 is described…
The dynamic rheological behavior of high density polyethylene (HDPE)/ultrahigh molecular weight polyethylene (UHMWPE) blends, low density polyethylene (LDPE)/UHMWPE blends and linear low density polyethylene (LLDPE)/ UHMWPE blends was measured in parallel plate rheometer at 200°C. The analysis of log-additivity rule,…
Chitosan and its derivatives have been proposed as bactericidal and fungicidal agents against a large numbers of gram-negative and gram-positive bacteria and fungi. Some antimicrobial mechanisms have been proposed for chitosan, with the most widely acceptable being the presence of charged-NH3+ groups in the polymer ba…
Amorphous chalcogenides usually exhibit a resistivity, which increases with age following a power law ρ ∼ tα. Existing theories link this change in amorphous state resistivity to structural relaxation. Here, the impact of fundamental glass properties on resistance drift phenomena in amorphous GexTe1−x networks is stud…
Bismuth chalcogenides, such as p-type (Bi,Sb) 2 Te 3 and n-type Bi 2 (Te,Se) 3 , are known to have excellent thermoelectric properties at temperatures near room temperature. Since Bi 2 Te 3 , Sb 2 Te 3 and Bi 2 Se 3 have the same class of crystal symmetry, they can form homogeneous solid solutions. The thermoelectric…
Gold nanoparticles were prepared by green route using Couroupita guianensis leaves extract. The green synthesized gold nanoparticles exhibited maximum absorbance at 526 nm in the ultraviolet spectrum. By incorporating the green synthesized gold nanoparticles in poly(vinyl alcohol) matrix, unique green organic-inorgani…
People’s inclination toward medical textiles for healthy life style has created a rapidly increasing market for antimicrobial textiles, which, in turn, has stimulated intensive research and development. The aim of our study was to prepare cellulose fabrics finished by allicin-conjugated nanocellulose, whose properties…
A two-step colloidal lithography process (Langmuir–Blodgett dip coating + reactive ion etching) was developed to fabricate single and double-sided moth-eye structures in Si, Ge, and GaAs for antireflection applications in the IR. Large increases in transmittance were obtained in all three material platforms (up to 97%…
Graded index -near-zero (GRIN-ENZ) quasi-optical components such as beam steerers and power splitters are designed, simulated and analyzed. The GRIN-ENZ medium is realized using stacked narrow hollow waveguides whose infinite array shows the first transmission peak at 1.0002 THz. Several GRIN-ENZ beam steerers to chan…
Abstract Colloidal silver nanoparticles were prepared by rapid green synthesis using different tannin sources as reducing agent viz. chestnut (CN), mangrove (MG) and quebracho (QB). The aqueous silver ions when exposed to CN, MG and QB tannins were reduced which resulted in formation of silver nanoparticles. The resul…
Abstract The chemical and sorption properties of clay minerals from the Mako area, Senegal, were investigated using FTIR spectroscopy, X-ray diffraction, scanning electron microscopy equipped with an X-ray energy dispersion spectrometer, thermal analysis and chemical analysis. The clay sample is essentially dominated…
Sericin is a globular water-soluble protein that constitutes 25 to 30 % of silk proteins weight in silkworm`s cocoons. This protein envelopes silk fibers gluing them and ensuring the cohesion of the cocoon. During raw silk production, sericin is separated from silk fibers and it is discarded in wastewater, leading to…
