A simple hydrothermal approach for coating of Zn_(1−x)Al_xO nanocrystals on cotton fabrics was developed. The phase, microstructures, and the ultraviolet protection properties of the samples were characterized by using X-ray diffraction (XRD), scanning electron microscopy (SEM) and ultraviolet-visible spectrophotometry. The results showed that for 2 and 4 atom% Al-doped ZnO, a large number of small particles with diameters of 50 ∼ 300 nm was obtained, which provided excellent protection from solar irradiation, and that the UV-blocking property of the fabric could be improved by increasing the Al-doping in ZnO. In addition, the cotton fabric coated with Aldoped ZnO nanoparticles showed surface-enhanced Raman scattering properties, which might have been caused by a charge-transfer resonance.
Effects of dye etching on the morphology and performance of ZnO nanorod dye-sensitized solar cells
Yu Lin,Jiyuan Yang,Yongming Meng 한국화학공학회 2013 Korean Journal of Chemical Engineering Vol.30 No.11
Dye-sensitized solar cells based on electrodeposited ZnO nanorod arrays were fabricated and tested. Fieldemission scanning electron microscopy (FESEM) and X-ray powder diffraction (XRD) were used to identify the characters of ZnO nanorod arrays. The effects of dye etching on the morphology and performance of ZnO nanorod dye-sensitized solar cells were studied. It was found that the surfaces of ZnO nanorods were both etched by dye solutions, no matter N3 or N719. Compared with N3, N719 had a larger damage to the structure of ZnO nanorod photoanode, and the photoelectric conversion efficiency of cells decreased quickly with the sensitizing time increasing. In a certain range, the increasing length of ZnO nanorods can clearly improve the photoelectric conversion efficiency of cells.

In this paper, an adaptive fuzzy event-triggered control scheme is investigated for a class of nonlinear switched systems with dead zone nonlinearity. Fuzzy logic systems are employed in identifying unknown nonlinear functions. Then, the dynamic surface control (DSC) method is exploited to overcome the problem of “explosion of complexity” in traditional adaptive backstepping recursive design process. Based on the Lyapunov stability theory and the backstepping technique with the event-triggered mechanism, the proposed control method proves that all the closed-loop system signals are bounded, and the tracking error converges to a small neighborhood of the origin under the arbitrary switching. Simultaneously, this control method proves that Zeno behavior can be eliminated. The simulation results also illustrate the validity of the developed control method and theorem.
The role of PDIA3 in myogenesis during muscle regeneration

Beta 3 (β3) integrin plays an important role in the initiation of myogenesis in adult muscle. Protein disulfide isomerases (PDIs) can activate β3 integrin in various cells to promote cell migration, adhesion and fusion. However, the effect of PDIs on myogenesis during muscle regeneration has not been elucidated. Here, we report that PDIA3 expression is induced in regenerating myofibers. The inhibition of PDIA3 in muscle injuries in mice disrupts myoblast differentiation, impairs muscle regeneration, and ultimately aggravates muscle damage. Moreover, PDIA3 expression is upregulated and observed on the cell surfaces of myoblasts during differentiation and fusion. The inhibition of extracellular PDIA3 with an anti-PDIA3 monoclonal antibody attenuates β3 integrin/AKT/mTOR signal activity, inhibits myoblast differentiation, and blocks the fusion of myoblasts. Thus, PDIA3 may be a mediator of myoblast differentiation and fusion during muscle regeneration.
