Microwave (MW) technology relies on volumetric heating, where thermal energy is induced from an electromagnetic field. Nowadays, the main drawback of this technology is that the complex physics involved in the conversion of electromagnetic energy into thermal energy is not entirely understood and controlled. The main objective of this work is to mo...

Background This study aimed to assess the surgical outcomes of two kinds of demineralized bone matrix (DBM) putties/local autograft composites in instrumented posterolateral lumbar fusion (PLF). Methods Twenty-seven fusion segments of 19 patients, who underwent decompression and instrumented PLF for lumbar spinal stenosis or degenerative spondyloli...

Praseodymium doped TiO2 nanoparticles were successfully prepared by the sol–gel method and characterized by X-ray powder diffraction, N2 adsorption–desorption isotherm, and UV–vis spectroscopy. The effects of the dopant on the crystallite size, specific surface area, average pore diameter, pore volume, and bandgap energy were investigated. The phot...

AbstractIn the present study, pectin-alginate-titania (PAT) composites were synthesized and the adsorptive removal behavior of methylene blue (MB) from aqueous solution, as a model of synthetic organic effluents, onto the prepared PAT composites were investigated by monitoring the effect of contact time, initial MB concentration, and temperature. T...

This study presents the tensile properties and cost-property efficiency analyses of a novel composite material type composed of expanded polystyrene as filler, chopped glass fibers as reinforcement agent and epoxy resin as matrix material. Composite specimens were fabricated via expanded polystyrene beads with two different densities, two different...

In this paper, we designed and prepared a novel metal organic framework (MOF)/holey graphene (HG) composites as electrode materials for electrochemistry and capacitive deionization (CDI). The MOF nanoparticles were attached to the surface of the HG sheets to form layered porous structure, which promoted the transport of ions and electrons in the el...

Starch-g-polyacrylamide copolymer and its nanocomposite with Fe3O4 and graphene oxide have been successfully synthesized. The synthesized samples were characterized using FTIR, XRD, SEM, HRTEM, and VSM. The factors that affect the adsorption efficiency of samples for Ni(II) ions from aqueous solutions as pH, initial Ni(II) ions concentration, conta...

Molybdenum disulphide (MoS2) is widely used in tribological applications because of its solid lubricating properties. However, its performance needs to be further improved. In this work, an attempt has been made to improve the tribological performance of MoS2 coating by incorporating TiO2 nanoparticles as a reinforcement material into the MoS2 base...

Germanium-based ternary oxides have aroused wide attention as an anode for high-performance lithium-ion batteries (LIBs). Nevertheless, they usually suffer a large volume expansion and rapid capacity fading during lithiation/delithiation cycles. To address this issue, herein, Zn2GeO4/RGO composites are synthesized with Zn2GeO4 hollow rods in-situ g...

In this paper, the Co/CoO composite was prepared via polyol reduction method, and the Co/CoO was wrapped by reduced graphene oxide (RGO) synthesized with Hummers’ method. The crystal texture, element composition, micromorphology, magnetic properties, and electromagnetic absorption performance of the composite were tested. Compared with the single R...
