Black phosphorus quantum dots (BPQDs) have been prepared by a high turbulent shear rate generated from household kitchen blender. A layer-by-layer disintegration mechanism of bulk BP crystals is suggested. As-synthesized BPQDs shown excellent humidity sensing and photothermal converting properties. Importantly, this work not only explores potential applications for the but also provides successful paradigm preparing QDs other layered materials.
Abstract BACKGROUND: The risk of environmental pollution is aggravated by the increasing application considerable amounts rare earth elements in advanced materials. This paper reports preparation novel magnetic alginate–chitosan gel beads and their for adsorption lanthanum ions from aqueous solution. RESULTS: Stable with average diameter 0.85 ± 0.05 mm were prepared loading iron oxide nanoparticles onto a combined alginate chitosan absorbent. performance solution was tested. It found that...
The adsorption of sulfadiazine from water by expanded graphite (EG), a low cost and environmental-friendly adsorbent, was investigated. Several parameters (including the initial concentration, contact time, pH solution, ionic strength temperature) were studied. Results equilibrium experiments indicated that onto EG better described Langmuir Tempkin models than Freundlich model. maximum capacity is calculated to be 16.586 mg/g at 298 K. kinetic data analyzed pseudo-first-order,...
A positively charged composite hollow fiber nanofiltration (NF) membrane was prepared via interfacial polymerization (IP) between chitosan lactate (CL) and trimesoyl chloride (TMC) on a polyether sulfone (PES) ultrafiltration (UF) membrane. The chemical structure the morphologies of resultant NF membranes were characterized with attenuated total reflectance-infrared spectroscopy (ATR-IR) scanning electron microscopy (SEM). rejection for different inorganic salt aqueous solutions followed...
A novel positively charged composite nanofiltration (NF) membrane with tunable active layer structure was successfully developed via interfacial polymerization on a polysulfone (PSF) ultrafiltration (UF) surface, using polyethyleneimine (PEI) as the monomer of aqueous phase, and mixture isophthaloyl dichloride (IPC) tri-mesoyl chloride (TMC) organic phase. Interestingly, synergetic effect mass ratio IPC TMC observed pore size resultant polyamide (PA)/polysulfone NF membrane. The rejection...
Hollow fiber composite NF membranes with improved anti-fouling property and water flux were prepared via interfacial polymerizationand layer-by-layer method using polyethylenimine (PEI), isophthaloyl dichloride (IPC), β-cyclodextrin (β-CD). The chemical structures the morphologies of resultant characterized by attenuated total reflectance-fourier transform infrared (ATR-FTIR) spectroscopy scanning electron microscopy (SEM). effects β-CD concentration on membrane morphologies, nanofiltration...
A novel kind of pH-stable positively charged composite nanofiltration (NF) membrane with excellent rejection performance was developed via interfacial polymerization on the surface a polysulfone (PSF) ultrafiltration (UF) membrane, using mixture polyethyleneimine (PEI) and piperazine (PIP) as monomers aqueous phase, cyanuric chloride (CC) monomer organic phase. The strong electron withdrawing steric hindrance effects group in molecules CC could protect amido bond from attack hydrogen ions...
ZnO buffer layers have been used in the hydride vapor phase epitaxy of GaN order to improve initial nucleation and growth hence subsequent materials properties. The specific role layer was investigated by x-ray photoelectron spectroscopy diffraction. improvements behavior are attributed formation a thin surface ZnAl2O4 that results from reaction-diffusion process between Al2O3. This can provide an improved lattice match as well change energy affecting GaN.
A novel composite, CdS nanorods growing on a polyaniline-Cd2+ particles surface (CdS/PANI) with hexagonal wurtzite structure phase, was prepared using hydrothermal synthesis method. Methods of XRD, SEM, and FTIR were used to analyze the morphology compounds. SEM shows that CdS/PANI consists sea urchin-like about 200-500 nm in length 50 diameter. Furthermore, spectra show some characteristic peaks are much weaker than those PANI corresponding shift higher wavenumber. In addition, IR...
We compared the CO<sub>2</sub> sensing properties of La<sub>1−x</sub>Ba<sub>x</sub>FeO<sub>3</sub> packed powder and thick film sensors.
Pd-SmFeO<sub>3</sub>is functionalized by mixing PdCl<sub>2</sub>with nanocrystalline powders and subsequently followed an annealing at 750 °C.
Adsorption of crystal violet (CV) onto amino silica (AS) was investigated as a function parameters including aqueous pH, temperature, AS dose, contact time, agitation speed, and initial CV concentration. And the optimum conditions obtained from response surface methodology (RSM) were temperature 33°C, dosage 0.35 g, time 64 min, speed 230 rpm. The adsorption equilibrium using Langmuir Freundlich models indicated that process followed isotherm maximum capacity reached 40 mg g−1. After both...
