Currently, graphene and its functional derivatives are in high demand due to their unprecedented potential build multifunctional catalysts. Here, we report the synthesis of highly active cheap photo-catalyst materials consisting sol-gel synthesized ZnO nanochips, assembled over oxidized (GO) partially reduced (RGO) presence ultrasound radiations. Structure, crystallite size, morphology, optical photo-catalytic properties as ZnO@GO, ZnO@RGO nanocomposites were investigated. Results...
In the present study, we explored whether different characteristics of graphene oxide prepared via two routes have been modified. It was observed that samples obtained both nearly same physico-chemical characteristics. Spectral (FT-IR and UV-vis) studies showed synthesis optical properties materials respectively. Optical band gap (Eg) found to be in range 3.1–3.9 eV. Thermal demonstrated exhibited stability up 550 °C. X-ray diffraction evaluated semi-crystalline nature with crystallite size...
A 2D-metal–organic frameworks/graphene oxide membrane that combines the electrostatic self-assembly of electronegative GO sheets and electropositive MOF sheets, which exhibits high mechanical flexibility, superior Cs<sup>+</sup> sorption, is presented.
The inherently poor flame retardancy and comparatively low tensile strength of poly(lactic acid) (PLA) have limited its wide adoption as alternative 'green' engineering plastic in many fields.This manuscript reports the synthesis a new phosphorus retardant -phenylphosphonic 3(2-aminobenzothiazole) (P-TAB) combination with recycled short wool fibers (WF) for improving mechanical properties PLA.Fourier transform infrared (FTIR), 1 H, 13 C nuclear magnetic resonance (NMR) spectra proved that...
Abstract The electric breakdown strength ( E b ) is an important factor that determines the practical applications of dielectric materials in electrical energy storage and electronics. However, there a tradeoff between constant dielectrics, typically lower than 10 MV/cm. In this work, ferroelectric thin film (Bi 0.2 Na K La Sr )TiO 3 with 115 found to exhibit ultra-high = 10.99 MV/cm, attributing high-entropy effects could result dense nanostructures refined grains, low concentration oxygen...
In this work, amorphous Fe-Co-P films prepared by electrodeposition are found to exhibit dense microstructures with grains. Through a pulse synthesis route, complex containing nano-sized grains obtained in the alloy films. The nanostructured alloys show superior soft magnetic and magnetocaloric properties as compared those of other iron-based reported date. coercive field samples can be small 1.6 Oe at room temperature. effect (MCE) ternary has been investigated evaluating entropy changes,...
The hetero-interfaces within NiO/Cu/Cu<sub>2</sub>O endow the porous N-doped carbon with fast Na<sup>+</sup> diffusion, high electrical conductivity, and improved sodium storage.
In order to enhance and tune the electrocaloric effect (ECE) ferroelectric responses, nanocomposites containing copolymer poly(vinylidene fluoride trifluoroethylene) two-dimensional (2D) graphitic-C3N4 (g-C3N4) are synthesized. The effects of g-C3N4 on ferroelectric-to-paraelectric phase transition investigated by differential scanning calorimetry (DSC), P-E hysteresis loop dielectric spectrum measurements. results indicate that addition 2D in is an effective approach enhancing its...
Ammonia borane (NH3BH3, AB) hydrolysis is an effective strategy to utilize hydrogen energy. In this work, the hierarchical porous CuNi bimetal-organic frameworks (CuNi-MOFs) are fabricated through a facile solvothermal method and characterized by various techniques. The CuNi-MOFs display outstanding catalytic activity remarkable durability for hydrolytic dehydrogenation of AB. corresponding turnover frequency reaches 40.85 molH2 · molMetal−1 min−1 apparent activation energy (28.99 kJ mol−1)...
In this study, effect of surface roughness on adhesive bonding aluminum (AL 6061 T6) substrates is investigated to determine the required bond strength between and adherends interface. Quality AL T6 lap shear joints (adherend preparation) achieved by mechanical abrasion using diverse grades silicon carbide sheets (P 320C, P 220C 180C). Lab grade acetone utilized for removal impurities from substrate while Loctite 4090 served as joints. Surface measured profilometer (SURFTEST SJ-210)....
