During the fabrication of poly(lactide-co-glycolic acid) (PLGA) microspheres by water/oil/water (W1/O/W2) emulsion solvent evaporation method, water permeation coupled with dichloromethane (DCM) volatilization represents a critical process affecting microsphere morphology. In this work, mechanism pore formation in PLGA through has been verified. By molecular simulations, diffusion coefficients different DCM contents were determined. The results showed that coefficient decreased rapidly from...
Yttrium aluminum garnet (YAG, Y 3 Al 5 O 12 ) nanoparticles were synthesized by ultrasound‐assisted and ultrasound‐microwave‐assisted alkoxide hydrolysis precipitation methods. The effect of reaction parameters including pH value, ultrasonic radiation time, calcination temperature on the composition products was investigated. YAG their precursor characterized X‐ray powder diffraction (XRD), differential thermal analysis (DTA), Fourier‐transform infrared spectroscopy (FT‐IR), high‐resolution...
Abstract The glass ceramics were prepared by a reaction crystallization and sintering method using waste powder crystallizing promoter with main crystal phase of the enstatite. X-ray diffraction(XRD), Scanning electron microscope(SEM), Differential scanning calorimetry(DSC), etc. used to characterize its composition, morphology, thermal decomposition process. results show that was diopside secondary albite. precipitated crystals rod-shaped maximum length about 7 μm diameter 0.6 μm. Diopside...
YAG and Yb:YAG transparent ceramic nanopowders for laser crystal were synthesized by microwave-assisted alkoxide hydrolysis precipitation method. The characterized differential thermal analysis thermo gravimetric (DTA-TG), infrared spectrum (IR), X-ray diffraction (XRD), field emission scanning electron microscope (FESEM) photoluminescence (PL) spectrum. results show that the crystallizing temperature of precursor is about 930 °C. pure phase can be obtained at microwave radiation power 385...
Diopside glass-ceramics were prepared by reactive crystallization with mixed powder of waste glass and mullite. The effects mullite content sintering temperature holding time on the crystal phase morphology diopside investigated. crystallizing behavior between was studied using energy dispersive spectrdmeter during process. result show that optimum preparation conditions as follows: addition 30 wt% used promoting agent, 900 °C 2h. main difference method traditional preparing mechanism....
The cube and hexagonal prism zinc oxide (ZnO) microstructures have been controllably synthesised by the facile liquid precipitation method using sodium dodecyl benzene sulphonate cetyltrimethyl ammonium bromide as surfactant separately. probable formation mechanism is also proposed based on experimental results. photoluminescence characterisation of ZnO structures exhibited a strong blue emission at 470 nm intensity improved ∼60% more than ZnO. photocatalytic activities were investigated...
The flower-like and hexagonal flake-like ZnO microstructures were synthesised by a microwave method using ammonia water sodium hydroxide as precipitant, respectively. products characterised scanning electron microscopy, high-resolution transmission X-ray diffraction photoluminescence. photocatalytic activity of the was evaluated degradation methyl orange (MO) under ultraviolet (UV) light irradiation. results indicated that best microstructure obtained when experimental conditions [Zn2+] =...
The Thermal Decomposition Kinetics of Mg(OH)2 Modified with Sodium Dodecyl Benzene Sulfonate (SDBS) by the Liquid Phase Method Was Investigated Using Differential Analysis and Thermo Gravimetric (DTA-TG) at Different Heating Rates. Results Show that Mg(OH) 2 SDBS Is Hexagonal Structure. Average Apparent Activation Energy Stages Calculated Doyle-Ozawa Kissinger Methods as 169.13 Kj•mol-1. Reaction Order Frequency Factor Can Be Also Determined Method. Equations Were Deduced Dα/dt = (5.71×10 12...
