A novel ionic liquid functionalized magnetic nanoparticle was prepared by anchoring an imidazolium ionic liquid bearing triethylene glycol moieties on the surface of silica-coated iron oxide nanoparticles. The material proved to be an effective host for the immobilization of a Pd catalyst through a subsequent simple i…
Near-neutral electrolytes based on zinc chloride and ammonium chloride are examined for rechargeable zinc-air battery application. The effects of pH value, salt concentration, and polyethylene glycol and thiourea additives are investigated and a chloride electrolyte is developed. The reversible zinc deposition and zin…
An alternative route to prepare geopolymeric mortars yields a strong reduction of CO 2 emissions. Replacement of commercial waterglass by rice hull ash-derived waterglass does not significantly decrease the mechanical strength of geopolymeric mortars.
The recent extension of the orbital angular momentum (OAM) concept from optical to microwave frequencies has led some researchers to explore how well established antenna techniques can be used to radiate a non-zero OAM electromagnetic field. In this frame, the aim of the present paper is to propose a new approach to g…
In covering wounds, efforts should include utilization of the safest and least invasive methods with goals of achieving optimal functional and cosmetic outcome. The recent development of advanced wound healing technology has triggered the use of cells to improve wound healing conditions. The purpose of this review is…
MoS2 nanosheet@TiO2 nanotube hybrid nanostructures were successfully prepared by a facile two-step method: prefabrication of porous TiO2 nanotubes based on a sol-gel method template against polymeric nanotubes, and then assembly of MoS2 nanoclusters that consist of ultrathin nanosheets through a solvothermal process.…
Three novel carbazole-based molecules have been synthesized and successfully applied as hole-transporting materials (HTMs) of CH3NH3PbI3-based perovskite solar cells. In particular, the perovskite cell with SGT-405, having a three-arm-type structure, exhibited a remarkable photovoltaic conversion efficiency (PCE) of 1…
Polycrystalline and dispersed hydroxyapatite (HAP) nanoparticles were successfully prepared via a simple precipitation method with the aid of a new capping agent based on Schiff base compounds. After that, a composite of chitosan (CT), graphene oxide (GO) and HAP nanoparticles was synthesized by a freeze-drying method…
Tantalum oxynitride has been studied as an active photocatalyst under visible light, using a full potential linearized augmented plane wave method within the framework of density functional theory. The electronic and optical properties of TaON are calculated using local density approximation (LDA), generalized gradien…
TiO 2 -based nanomaterials could reach the maximal photoactivity when designing 0D/1D heterogenous structure with appropriate phase composition and high surface area.
Hybrid ZnO@Ag core-shell nanorods were synthesized using a novel seed mediated, two-step process and their plasmon-mediated, enhanced photocatalytic property was used for degradation of industrial textile dyes and effluents.
The combination of acidic zeolites and Fischer–Tropsch synthesis (FTS) catalysts for one-step production of liquid fuels from syngas is critically reviewed.
Apart from ceramics, polymers, and composites, metallic materials rank distinguished in the field of biomaterials. Recently, titanium (Ti) based materials are attracting much interest as implantable materials because of their superior corrosion resistance, better mechanical properties such as remarkably high specific…
Ultrathin two dimensional (2D) materials have triggered extensive interest for their exceptional properties and potential applications. Herein, atomic layer graphitic carbon nitride (g-C3N4) was obtained by a simple ultrasonic exfoliation approach, and cadmium sulfide (CdS) nanoparticles were successfully grown on the…
This paper presents an improved analytical method for calculating the magnetic field and cogging torque in the surface-mounted permanent-magnet (PM) machines accounting for any eccentric rotor shape. The magnetic field in the surface-mounted PM machines is predicted according to the surface-current method of the PM, t…
Novel BiOCl–g-C3N4 composite photocatalysts were synthesized by a one-step chemical bath method. The composites were characterized using X-ray diffraction (XRD), high-resolution transmission microscopy (HRTEM), UV-visible light diffusion reflectance spectrometry (DRS), Fourier-transform infrared spectroscopy (FT-IR),…
Graphene-based nanocomposites have been demonstrated to be promising high-capacity anodes for lithium ion batteries to satisfy the ever-growing demands for higher capacity, longer cycle life and better high-rate performance. Synergetic effects between graphene and the introduced second-phase component are generally ob…
