OAbstract. One of the approaches that has been done to produce a better performance of an intermediate temperature solid oxide fuel cell (IT-SOFC) is by varying the synthesis methods. This paper focused on the proton conducting electrolyte in particularly barium cerate and barium zirconate system namely BaCe0.9Y0.1O3-…
This paper presents the synthesis and characterization of Bi2Sr2Ca2Cu3O8+x superconducting nanowires. Bi2Sr2Ca2Cu3O8+x nanowires with Tc = 68 K were synthesized using the electrospinning process employing sol–gel precursors. A sol–gel methodology was used to obtain a homogeneous PVP solution containing Bi, Sr, Ca, and…
Copper nanoparticles were synthesized using laser ablation method by the reduction of copper plate in the presence of distilled water. Effects of time as the laser hits on the copper target were increased, the amount of Cu NPs in the distilled water also increased. EDAX confirms the existence of Cu NPs. The metallic n…
Mixed matrix membrane (MMM), a developing research area, is a membrane formed by incorporating fillers in the polymeric membrane to enhance gas separation performance. In this study, MMMs comprised of blend rubbery block copolymers of polyether block amide (Pebax-1657) with a glassy polyethersulfone (PES) polymer and…
Lubricated sliding wear of amorphous (Zr55Cu30Ni10Al5)99.98Sc0.02/CuZr2 nanocrystal composite bulk metallic glasses (BMG) under various sliding velocities with a load of 20 N was investigated using the pin-on-disk test. After the wear test involving oil lubrication was performed, there was no wear induced new-phase tr…
It is well known that organic solar cells (OSCs) are made using organic materials because of their mechanical flexibility and low manufacturing cost. Their efficiency, however, remains low for several reasons, including limited light absorption and poor charge mobility. Although OSCs are a fascinating supplement to si…
The deformations induced by an electric field in nematic liquid crystal layers can be homogeneous (i.e. one-dimensional) or spatially periodic (i.e. two-dimensional). The periodic deformations take the form of parallel stripes visible under a microscope. They are particularly favoured when the nematic material possess…
This chapter focuses on polymer-toughening methodology for three of the more demanding polyurethane polymer applications, namely, reaction injection molding (RIM), flexible foams, and dynamic elastomers. In the truest sense, the development of new polymers to meet the ever-changing needs of automotive exterior applica…
The release of untreated dyes into water bodies leads to serious environmental complications because of high toxicity and high Chemical Oxygen Demand (COD). There are many techniques available to degrade dye color out of which the adsorption method, owing to its economic feasibility and simplicity in design makes it m…
Small-angle neutron scattering (SANS) has been utilized for micro-structural investigation on laboratory heats of oxide dispersion strengthened (ODS) 13.5 Cr wt % ferritic steel, with 0.3 wt% Y2O3 and with variable Ti and W contents. The results show that increasing the Ti content from 0.2 to 0.4 wt% a distribution of…
There are four commonly practiced processes for the production of impact-modified styrenics. These processes are bulk, bulk suspension, emulsion, and blending. During the polymerization, grafting occurs on the rubber backbone by either hydrogen abstraction of an allylic hydrogen or addition to a double bond. Emulsion…
This note considers Sturm oscillation theory for regular matrix Sturm-Liouville operators on finite intervals and for matrix Jacobi operators. The number of space oscillations of the eigenvalues of the matrix Prufer phases at a given energy, defined by a suitable lift in the Jacobi case, is shown to be equal to the nu…
Today, the development of building materials based on toxic or non-toxic industrial waste is a topical issue for the productive structures in industrialized countries. In this article, non-toxic wood waste (wood chips) is used to improve the characteristics of ordinary concrete (lightness, thermal insulation, acoustic…
The development of integrated vertical III-V nanowire (NW) stimulated emitters in silicon photonics while achieving an efficient light coupling through vertical III-V NW lasers into horizontal optical silicon waveguides is demanding. This is mainly due to the directionality and contradiction of the simultaneously sati…
The present study involves the fabrication of CH and CH-Ag hydrogel beads and the investigation of the antimicrobial properties. The beads were fabricated using a simple coacervation method. The successfully synthesized beads were characterized by UV-Vis and FTIR. The surface morphology, shape and diameter of the samp…
Two series of benzoxazines were synthesized from o-, m-, and p-methoxyphenols, two polyetheramines with different molecular weights, and formaldehyde. The glass transition temperatures (Tgs) of m-methoxyphenol-based polybenzoxazines are respectively higher than those of o- and p-methoxyphenol-based counterparts. The p…
The present article reports the growth mechanism of zinc oxide (ZnO) nanowires grown on silicon substrate pre-coated with ZnO buffer layer by thermal evaporation method. ZnO nanowires are grown for different growth time of 0, 30, 90 and 120 mins with controlled supply of Ar and O2 gas at 650 °C. The structural, morpho…
A single layer of BiFeO3 (BFO)/epoxy resin composite with thickness of 3 mm was fabricated by polymerized 70 wt% of sintered BFO as fillers and 30 wt% of epoxy resin polymer as matrix. The electromagnetic and the microwave absorption properties of BFO/epoxy resin composite were reported. The reflection loss (RL) of th…
The activated carbon produced from oil palm empty fruit bunches (ACEFB) shows good properties to act as a dispersing agent in the synthesis of BCZY ceramic material. However, the untreated ACEFB (u-ACEFB) shows some impurities still present after calcination. Thus, it has to be functionalized (f-ACEFB) by using chemic…
Abstract The physical and chemical properties of typical nitrate energetic materials under hydrostatic compression and uniaxial compression were studied using the ReaxFF/lg force field combined with the molecular dynamics simulation method. Under hydrostatic compression, the P–V curve and the bulk modulus (B0) obtaine…
