Stable and even microcrystals of Avermectin (AVM) were produced by recrystallization in presence of a stabilizer. Sequential layer growth was achieved by the layer-by-layer (LbL) self-assembly of biocompatible polyelectrolytes (PEs). The coated colloids were characterized using confocal laser scanning microscopy (CLSM) and scanning electron microscopy (SEM). The in vitro release of Avermectin from microcapsules was studied under the simulated insect midgut conditions. W-doped TiO(2) photocatalysts were synthesized by a simple hydrothermal method, and characterized by Brunauer-Emmett-Teller (BET) surface area measurements and SEM. The photocatalytic activities of photocatalysts, which were undoped with TiO(2) and W-doped TiO(2), were evaluated by the photocatalytic oxidation degradation of AVM microcapsules in aqueous solution under UV illumination. The toxicity of the photodegradable insecticide was evaluated by the adult stage Martianus dermestoides. The results showed that AVM microcrystals which were obtained by association had a mean length of 13.8μm and a zeta potential of -34.7mV. The drug loading and encapsulation efficiency were 65.57±0.96% and 46.15±0.96%, respectively. The in vitro release experiments revealed that the polyelectrolytes prolonged the release time of the encapsulated AVM microcrystals. The sample which was prepared at 120°C with 4.0mol% W-doped amount had the highest photocatalytic activity. Toxicity of the novel photodegradable insecticide was higher in the adult stage compared to the 95% AVM as indicated by the lower LC(50) value. 相似文献

A simple thermal decomposition route has been developed to prepare single-phase cubic ZrO2 nanospheres by [Zr(sal)3(H2O)2](NO3) as the new precursor. The ZrO2 nanocrystals have been prepared by bis-aqua, tris-salicylaldehydato zirconium(IV) nitrate; [Zr(sal)3(H2O)2](NO3), as precursor in oleylamine (C18H37N) and triphenylphosphine (C18H15P). To control the particle size, combination of C18H37N and C18H15P were applied as surfactants. The C18H37N and C18H15P play an important role in preventing aggregation of ZrO2 nanocrystals. The products were characterized by X-ray diffraction, transmission electron microscopy, photoluminescence spectroscopy, and Fourier transform infrared (FT-IR) spectroscopy to depict the phase and morphology. The FT-IR spectrum showed the purity of obtained ZrO2 nanocrystals with cubic phase. 相似文献

A 16-spark-gap camera was used to record the dynamic photoelastic patterns of ten centrally cracked, Homalite-100 specimens
which fractured under ten initial biaxial-stress ratios ranging from 3.7 to 0, some of which do not exist in normal fracture
specimens. The dynamic photoelastic patterns of curved cracks were used to verify the previously developed dynamic-crack-curving
criterion. Cracks which immediately curved upon propagation in three specimens under abnormally high inital biaxial loading
were used to verify the static counterpart of the dynamic-crack-curving criterion under these extreme loading conditions.
A previously developed dynamic-crack-branching criterion was also verified by four dynamic photoelastic results involving
cracks which eventually branched under the lower initial biaxial loading. 相似文献

Benzyl alcohol and Rose Bengal were loaded and entrapped using linear–dendritic macromolecules by two procedures. In the first
procedure, benzyl alcohol was attached to the end functional groups of linear–dendritic macromolecules by ester bonds to afford
linear–dendritic–host conjugates. In the second procedure, entrapment was based on physical interactions between Rose Bengal
and linear–dendritic macromolecules; this procedure is known as complexation method. Loading and binding capacity of different
linear–dendritic macromolecules was investigated using 1H nuclear magnetic resonance (NMR) and UV spectroscopy methods. It was found the loading or binding capacity of linear–dendritic
macromolecules depends on their generation, so that higher generations have higher loading or binding capacity. Diameter of
nanocarriers was investigated using dynamic light scattering (DLS) experiments, and it was between 16 and 50 nm for different
nanocarriers. Release of guest molecules from nanocarriers was evaluated at pH 1, 7.4, and 10.
