Explosion welding of metals is a process of great technological significance in terms of modern metal composites manufacturing possibilities Nevertheless, selecting welding parameters is not an easy task. This paper assesses the effect of various values of distance of sheets on the quality of the bond zone in titanium…
PEGylated PPI dendritic scaffold was used for the delivery of an anti-leukemic drug, Prednisolone. The current study evolves and emerges the use PEGylated poly dendritic scaffold for the delivery of this drug. In this the prednisolone was loaded and synthesized with PEGylated PPI dendritic scaffold. Estimated the biod…
We show that effective field theory techniques can be applied in the high temperature T regime of plasmas to improve the accuracy of the physics of the hard scales (or scales of order T), and as a by-product, also that of the soft scales (or scales of order gT). At leading order in the coupling constant the hard scale…
The mechanisms for OH-initiated acenaphthylene degradation reactions are investigated theoretically by using the density function theory method at M06-2X/aug-cc-pVTZ level in the present paper. There are two possible reaction pathways for the degradation processes have been predicted: the hydrogen abstraction pathway…
Abstract. Crystallization fouling is one of the major problems in process industries using water. In the present work the precipitation of calcium carbonate (CaCO3), and of mixed calcium carbonate - calcium sulfate (CaSO4) deposits on the walls of a heated metal surface of stainless steel was investigated. All experim…
VO 2+ doped SnO2 thin films have been prepared on ultra-clean glass substrates by chemical spray pyrolysis technique. UV-vis, PL, Electrical conductivity and chromaticity studies were investigated on VO 2+ doped SnO2 thin films. Optical absorption spectrum showed three bands at 753, 720 and 610 nm in the wavelength ra…
The Green–Tao–Ziegler theorem provides asymptotics for the number of prime tuples of the form $(\psi_1(n),\ldots,\psi_t(n))$ when $n$ ranges over the integer vectors of a convex body $K\subset [-N,N]^d$ and $\varPsi=(\psi_1,\ldots,\psi_t)$ is a system
Abstract. Flow reduction due to scale deposition within the downhole utilities, valve applications, and tubular is recognised as one the major flow assurance problems affecting production in the oil and gas sector. Most of the literatures investigating similar mineral fouling mechanism mainly focused on either a labor…

The relatively low breakdown voltage (BV) seriously restricts the high power application of GaN based high electron mobility transistors (HEMTs). In this work, a novel AlGaN/GaN HEMT with buried p-n junctions is investigated to improve the breakdown characteristics by introducing six equidistant p-GaN islands buried b…
This study has focused on the recycling of carbon fiber-reinforced thermoplastics (CFRTP) based on polyethersulfone (PES) that have a high thermal stability from the viewpoint of reusing the carbon fibers (CFs). The first recycling method is the remolding of the CFRTP; i.e., the reuse of CFs through material reuse. Fr…

The spall behavior of copper at ultra-high strain rate is studied by molecular dynamics simulation combined with an experimental analysis of laser ablation of a bulk copper target by femtosecond laser pulses. In the molecular dynamics simulation, two-temperature model is used, shock wave and spallation characteristics…
This research studied the mechanical properties of particulates composite materials made from natural fillers (eggshell and sawdust) reinforced epoxy resin. The composite specimens were prepared by hand lay-up technique with one volume fraction Vf, and different particle size of fillers. Modulus of elasticity, tensile…
Abstract This chapter addresses the issue of stress-corrosion cracking (SCC) in carbon and low-alloy steels. It discusses crack initiation, propagation, and fracture in aqueous chloride, hydrogen sulfide, sulfuric acid, hydroxide, ammonia, nitrate, ethanol, methanol, and hydrogen gas environments. It explains how comp…
3, 3-Diindolylmethane (DIM) a dietary indole compound occur naturally as glucosinolate conjugates in Brassica vegetables has been extensively studied for its anticancer action both in vitro and in vivo models. Due to, its poor water solubility, its absorption upon oral administration has limited its clinical developme…
The wide range of applications of silver nanoparticles (AgNPs) in commercial products, including food packaging, has encouraged researchers to come up with novel preparation methods for the production of these robust materials. The methods resulting in the formation of NPs for such commercial applications clearly dema…
In recent years, gas‐insulated switchgear (GIS) become more and more important in the power grid. The distance between GIS shell and its internal conductor is short, which cause a strong electromagnetic coupling between these two parts. A travelling wave will occurred when the GIS isolating switch and circuit breakers…
The wide use of nanomaterials in medicine and especially in drug delivery had heightened the demand for a safe use of nanoparticles (NPs) before delivered to patients. NPs are used to reduce the toxicity of some drugs; however, the nanocarriers themselves impose risk on the patient health. The creation of NPs safe use…
Carbon nanotube reinforced aluminium matrix composites (Al-CNTs) have been widely used in aerospace and automotive industries where high quality and strength is required. The enhanced mechanical properties of Al-CNTs are closely related to processing technique due to challenges within production of these composite mat…
