Foam-filled enclosures are very common in structural crashworthiness to increase energy absorption. However, very less research has been targeted on potential use of natural/recycled material reinforced foam-filled tubes. Therefore, an experimental investigation was performed to quantify energy absorption capacity of…
Solid oxide fuel cell (SOFC) is currently popular due to its capability to convert hydrogen into electricity directly from oxidizing hydrogen fuel. The SOFC is one of the expected renewable energy devices and green technology in the future because of less carbon dioxide production and no pollutant product. Performance…
Abstract The magnetic response of electrons in a zigzag carbon nanotube (CN) threaded by an Aharonov Bohm fluxφis carefully analyzed by using a Hartree Fock approximation. The ground state energy as a function of the magnetic field,B, and the electron–electron repulsion strength,U, are obtained forNeinteracting electr…
The use of antifreeze in water mist fire suppression systems offers a potential alternative to the current applications of these systems in subfreezing environments. Design and development of these systems, however, requires quantitative data detailing the effect of antifreeze on factors, such as small droplet sizes a…
This paper evaluate previous experimental studies on sub-freezing start up of proton exchange membrane (PEM) fuel cell system, and identify issues for further investigation. In a successful cold start, product water from electrochemical reaction in the cathode must be removed from the cell before it turns into ice and…
This Study Successfully Synthesized Terbium-Doped Barium Zirconate Phosphor and Cerium-Doped Strontium Zirconate Phosphor and Europium-Doped Calcium Zirconate Phosphor Using the Sol-Gel Method. we Employed X-Ray Powder Diffraction ( XRD ) and Energy-Dispersive X-Ray Spectroscopy ( EDX ) and Photoluminescence Spectrosc…
The unique optical properties of Quantum Dots have attracted a great interest to use these nanomaterials in diverse biological applications. The synthesis of QDs by methods from the literature permits one to obtain nanocrystals coated by hydrophobic alkyl coordinating ligands and soluble in most of the cases in organi…
In both pharmaceutical and toxicological fields, one of major issues has been the possibility of nanoparticle uptake to central nerve system. For the safe use of nanoparticles, it is integral to evaluate the permeability of nanoparticles through BBB. In our collaborative research group reported that a few nanoparticle…
Nanomaterials are widely present in many industrial sectors (e.g., chemical, biomedical, environment), and their application is expected to significantly expand in the coming years. However, nanomaterial use raises many questions about the potential risks to human health and the environment and, more specifically, to…
This paper presents a review of recent developments of nonlinear constitutive material models for the applications in high speed ballistic impact of projectile into several types of targets. The objective is to comprehend some numerical approaches that have been proposed and used in the technical literatures especiall…
As device features continue to shrink, achieving acceptable yields becomes increasingly challenging. In the photolithography process, mask error is one of the most critical error sources, since any imperfections on a mask will be amplified and transferred onto a wafer due to Mask Error Enhancement Factor (MEEF) [1]. F…
Estimation of the life cycle cost (LCC) for a hydrogen internal combustion engine (H2ICE) that uses hydrogen as an alternative fuel by forecasting a financial investment plan for a period of five years (n = 5). This is influenced by the interest rate of 10% (i = 10). The effect of Annual Operating Cost and salvage val…
Although self diffusion activation energy of metal is known to be strongly correlated to its melting point and heat of formation, prediction of diffusion activation energy remains a challenge and somehow an art. On the basis of the well developed quasi-chemical model, we demonstrate a general frame work to estimate su…
Renal morphological parameters were determined in rats intratracheally instilled with model cadmium-containing silica nanoparticles (Cd-SiNPs, 1mg/rat), also exploring whether their potential modifications would be associated with toxicogenomic changes. Cd-SiNP effects, evaluated 7 and 30 days post-exposure, were asse…
Growth of aligned carbon nanotubes (CNT) by a secure injection CVD process on large quartz substrates and carbon fiber (CF) cloths has been reported in this study. Adjustments of CVD setup and synthesis parameters have been achieved to control the CNT growth in terms of homogeneous covering of the substrates and to ta…
We review the magnetic form factor deduced by Delrieu from Gorkov's equation for a Bardeen-Cooper-Schrieffer (BCS) type-II superconductor near its ${B}_{\mathrm{c}2}$ phase boundary, i.e., when its magnetization is small. A numerical study of the form factor, field map, and field distribution follows. The characterist…
The structure and magnetic properties of polycrystalline GdCo9Si2 compound have been investigated. It has a BaCd11 structure and undergoes two magnetic phase transitions: an antiferromagnetic to ferrimagnetic transition occurring at ∼93 K, and a ferrimagnetic to paramagnetic transition at 420 K, which results in a pos…
In this work, we studied the effect of surface treatment of the aluminium surface and a coupling agent to improve adhesion between aluminium with organic polymer. Thermoplastic natural rubber (TPNR) matrix was prepared by melt blending of natural rubber (NR), liquid natural rubber (LNR) as a compatibilizer, linear low…
Diamond coating on tungsten carbide (WC-Co) cutting tools with cobalt binder experiences delaminating failure due to the deleterious effect of cobalt. One of the methods used to reduce this effect is by coating an interlayer onto the substrate surface prior to diamond deposition. Different materials have been used as…
Abstract The dispersed phase of the polypropylene/maleinized poly(ethylene‐octene) (PP/mPEO) blend was modified by means of nanoclay addition, in an attempt to find out the effect of its modulus of elasticity on the location of the brittle/tough (B/T) transition. The nanoclay stayed only in the dispersed rubbery phase…
