Using graphene oxide (GO) as both a reducing agent and support, two-step method was used to fabricate GO decorated with Au–Ag alloy nanoparticles an Au-rich shell. The material exhibited excellent catalytic activity for the reduction of 4-nitrophenol 4-aminophenol in water at room temperature its superior that prepared by one-step either Au or Ag alone.
In this study, reduced graphene oxide (rGO) aerogels were successfully prepared using a facile hydrothermal method and determined with Fourier transform infrared spectroscopy, X-ray diffraction Raman photoelectron Brunauer-Emmett-Teller surface area, scanning electron microscopy. The rGO used to remove Pb(II) from aqueous solution, the adsorption performance of was investigated. addition, adsorption-desorption cycle experiments carried out evaluate recyclability stability aerogels. data...
Copper metal nanoparticles were used as a reducing agent to reduce graphene oxide (GO). The reaction was complete in about 10 min and did not involve the use of any toxic reagents or acids that are typically reduction GO by Zn Fe powders. high activity Cu nanoparticles, compared powder, may be result formation Cu₂O nanoparticles. effect mass ratio for this also investigated. verified ultraviolet-visible absorption spectroscopy, x-ray diffraction, thermogravimetric analysis, Raman...
A novel hybrid biomaterial composed of calcium sulfate (CS) and gelatin (GEL) was prepared with the potential being used as bone filler or scaffold owing to its osteoconduction. Such composite biomaterial, cross-linked un-cross-linked, could provide a suitable absorbing rate prevent CS crystals migrating from implant for tissue engineering. The structure analyzed infrared (IR) spectroscopy, X-ray diffraction (XRD) scanning electron microscopy (SEM). results indicated that crystal pattern...
Structural colors: Poly(N-isopropyl acrylamide) based microgel photonic crystals are fabricated by using a new method called "high-temperature-induced hydrophobic assembly". The assembling conditions affect the water content of crystals, thus determining their structural color (see image). obtained sensitive to solvents, and reversible changes in can be observed with naked eye.
Uniform and highly dispersed magnesium hydroxide nanoparticles were synthesized in cetyltrimethyl ammonium bromide/cyclohexane/isopropanol/water microemulsion. The effect of different experimental conditions on particle size was investigated the control mechanism discussed. results indicated that R value (R= [water]/[surfactant]) dosage isopropanol could by varying "water droplet" microemulsion; Mg2+ concentration mole ratio to OH− fine tune solution supersaturation water droplet. had...
The bone-repairing composite material CS/PLLA was fabricated by mixing poly-L-lactic acid (PLLA) and calcium sulfate hemihydrate (CSH). structure of the analyzed with Infrared spectroscope, X-ray diffraction, scanning electron microscope. results indicated that crystal pattern affected addition PLLA. PLLA part impacted development dihydrate (CSD) slowing conversion from CSH to CSD, so composites are actually composed CSH, absorbing test in vitro showed absorbed more slowly than pure CS,...
Porous chitosan/gelatin (CS/Gel) foams with ordered porous structures were prepared by a unidirectional freeze-drying method. The CS/Gel had high porosities. porosity of the foam depended on concentration preparation solution and ratio. affected compressive strength higher concentrations resulted in better strength. ratio both degradation rate foam. Low ratios rates. adsorption capacity for aqueous Pb2+ Co2+ ions fetal bovine serum. In addition, gentamicin loaded different release rates...
Abstract A core–shell structured Mg(OH) 2 /PS with enhanced surface lipophilicity was successfully synthesized by a microemulsion template. The core magnesium hydroxide prepared in cetyltrimethyl ammonium bromide (CTAB)/isopropanol/cyclohexane/water microemulsion, and the shell polystyrene (PS) formed situ adding styrene monomer into oil phase of microemulsion. nanoparticles were characterized X‐ray diffraction (XRD), scanning electron microscopy (SEM), photoelectron spectroscopy (XPS),...
Abstract As a high-quality water resource, deep ocean (DOW) has aroused widespread interest. In this study, ultrafiltration-reverse osmosis technology was used to desalinate prepare pure water. By controlling the process conditions, system obtained desalination rate of 98.3%, and product met requirement relevant standards.
During the investigation in South China Sea summer of 2018, sea water samples were for some trace elements (such as Cu, Zn, Fe Mn, Ni, Se, Mo, Co and V) analyses from different layers 12 stations according to standard sampling specifications. The seawater depths directly measured by inductively coupled plasma mass spectrometry. distribution was investigated investigated. It could be seen analytical results that contents Fe, V deep at have little change with depth, other vary greatly depth....
Abstract The definition, resource characteristics and application of deep seawater were introduced in this paper. Meanwhile, the current status development utilization resources at home abroad was summarized. Finally, prospects for are prospected.
