In recent years, two-dimensional (2D) materials of ferroelectricity have been illustrated to great potential in solar energy conversion processes such as photocatalytic water splitting, although the optical properties are rarely discussed. combination with first-principles calculations, many-body Green's function method was used obtain excited-state representative CuInP2S6 unravel ingredients affecting behavior. particular, quasiparticle (QP) band gap correction and bound exciton binding...
Abstract As new members of the two-dimensional materials family, MoSi 2 N 4 and WSi exhibit unique physical properties. However, their optical properties in consideration spin–orbit coupling (SOC) have not been discussed. In this work, excited-state monolayers are studied by means many-body perturbation theory combination with first-principles calculations. We find that quasiparticle correction leads to a large band gap renormalization more than 1 eV for monolayers. Because SOC,...
Bi-phase dispersible ZnO-Au hybrid nanoparticles were synthesized via one-pot non-aqueous nanoemulsion using the triblock copolymer poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol) as surfactant. The characterization shows that polymer-laced are monosized and of high crystallinity demonstrate excellent dispersibility optical performance in both organic aqueous medium, revealing effects quantum confinement medium. findings show two well-behaved absorption bands...
The polymer-coated AgZnO nanoparticles were synthesized via a one-pot process with the assistance of triblock copolymer, poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol) (PEO-PPO-PEO). characterized by Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM) including mode high resolution (HRTEM) and energy dispersive X-ray analysis (EDX), diffraction (XRD), photoelectron (XPS), ultraviolet-visible light absorbance spectrometry...
Background. Gallic acid (GA) has been shown to inhibit demineralization and enhance remineralization of enamel; however, GA solution is highly acidic. This study was investigate the stability solutions at various pH examine resultant effects on enamel demineralization. Methods. The in H2O or phosphate buffer 5.5, 7.0 10.0 evaluated qualitatively by ultraviolet absorption spectra quantified high performance liquid chromatography with diode array detection (HPLC-DAD). Then, bovine blocks were...
The bifunctional photocatalytic-adsorbent AgZnO/polyoxometalates (AgZnO/POMs) nanocomposites were synthesized by combining AgZnO hybrid nanoparticles and polyoxometalates [Cu(L)2(H2O)]H2[Cu(L)2(P2Mo5O23)]⋅4H2O (HL = C6H6N2O) into nanostructures via a sonochemical method. Transmission electron microscopy (TEM) indicated that AgZnO/POMs uniform with narrow particle size distribution without agglomeration. X-ray powder diffraction (XRD) photoelectron spectroscopy (XPS) analysis confirmed the...
Photocatalytic activity of monosized AuZnO composite nanoparticles with different compositions were synthesized by the one-pot polyol procedure, using triblock copolymer poly(ethylene glycol)-block-poly(propylene glycol)-blockpoly(ethylene glycol) (PEO-PPO-PEO) as surfactant.
