ZnO nanorod arrays(NRAs) were prepared via a facile hydrothermal method for photoelectrochemical(PEC) ***, ZnS thin shell layers were deposited onto them via a facile hydrothermal treatment process for constructing a ZnO/ZnS core/shell structure. It was demonstrated that the PEC activity of a ZnO NRA is enhanced significantly after the surface modification, although there weren’t any obvious changes in the visible-light harvesting *** the Nyquist and Mott-Schottky(M-S) plots were employed to reveal the reason, which was attributed to higher electrocatalytic activity of ZnS than that of ZnO and the resulting higher charge transfer efficiency across the solid/liquid interfaces. Finally, a schematic band model was proposed for clarifying the charge carrier transfer mechanism occurred at the interfaces.

Stable aqueous amino-grafted silicon nanoparticles （SiNPs-NH2） were prepared via one-pot solution method. By grafting amino groups on the particle surface, the dispersion of SiNPs in water became very stable and clear aqueous solutions could be obtained. By incorporating SiNPs-NH2 into the hole transport layer of poly（3,4- ethylenedioxythiophene）/polystyrene sulfonic acid （PEDOT＇PSS）, the performance of polymer solar cells composed of poly[2-methoxy,5-（2＇-ethylhexyloxy）-1,4-phenylene vinylene] （MEH-PPV）：[6,6]-phenyl-C61-butyric acid methyl ester （PCBM） as active layer can be improved. SiNPs-NH2 are dispersed uniformly in the PEDOT：PSS solution and help form morphologies with small-sized domains in the PEDOT：PSS film. SiNPs-NH2 serve as screens between conducting polymer PEDOT and ionomer PSS to improve the phase separation and charge transport of the hole transport layer. As a result, the sheet resistance of PEDOT：PSS thin films is decreased from （93 ±5） × 10^5 to （13 ± 3） × 10^5 Ω/□. The power conversion efficiency （PCE） of polymer solar cells was thus improved by 9.8% for devices fabricated with PEDOT＇PSS containing 1 wt% of SiNPs-NH2, compared with the devices fabricated by original PEDOT：PSS.

The rapid visco analyser （RVA） profile is an important factor for evaluation of the cooking and eating quality of rice. To improve rice quality, the identification of new quantitative trait loci （QTLs） for RVA profiling is of great significance. We used a japonica rice cultivar Nipponbare as the recipient and indica rice 9311 as the donor to develop a population containing 38 chromosome segment substitution lines （CSSLs） genotyped by a high-throughput re-sequencing strategy. In this study, the population and the parent lines, which contained similar apparent amylose contents, were used to map the QTLs of RVA properties including peak paste viscosity （PKV）, hot paste viscosity （HPV）, cool paste viscosity （CPV）, breakdown viscosity （BKV）, setback viscosity （SBV）, consistency viscosity （CSV）, peak time （PET） and pasting temperature （PAT）. QTL analysis was carried out using one-way analysis of variance and Dunnett＇s test, and stable QTLs were identified over two years and under two environments. We identified 10 stable QTLs： qPKV2-1, qSBV2-1; qPKV5-1, qHPV5-1, qCPV5-1; qPKV7-1, qHPV7-1, qCPV7-1, qSBV7-1; and qPKV8-1 on chromosomes 2, 5, 7 and 8, respectively, with contributions ranging from -95.6% to 47.1%. Besides, there was pleiotropy in the QTLs on chromosomes 2, 5 and 7.

以传统基于灵敏度分析的有限元模型修正方法为基础,提出一种结合小波去噪过程的正则化模型修正损伤识别方法。为改进模型修正方法损伤识别效果,一方面利用有损结构模态与模态噪声的波形在时频域内的差异,以结构有限元模型为基准,对实测模态差进行小波去噪处理,并利用修正后的模态构造目标函数;一方面采用正则化方法改善反问题求解的非适定性。由于从输入数据和求解过程两方面同时改善了结构损伤识别反问题的求解,因此可以有效抑制实测模态参数中噪声的影响,正确识别结构损伤。以连续梁桥模型为例的损伤识别数值模拟表明,所提出方法在保持识别算法鲁棒性、抑制噪声的同时,可有效提高桥梁结构损伤的识别精度。

生活垃圾与一般工业固废协同焚烧处理是生活垃圾焚烧产业发展的重要趋势,协同焚烧处理对炉渣中氯存在特性的影响,尚无相关报道.本文以典型的一般工业固废PCB板为实验对象,聚焦生活垃圾/废PCB板协同焚烧过程,查明不同垃圾组分下,焚烧炉渣样品中的氯迁移行为、存在形态及长期稳定性.结果表明,废PCB板高温分解出的玻璃纤维比表面积大,能捕获部分挥发性的氯,使得其残留于炉渣中,从而造成炉渣总氯含量提高,但垃圾组分中塑料占比对该过程有重要影响.协同焚烧的炉渣水溶性氯含量在50~70wt%之间.淋溶结果显示大部分炉渣中氯的残留率在40%以下,而随着废PCB板投加量增加,炉渣中氯的残留率回升,最高达45.6%,这表明协同焚烧抑制了炉渣中氯的浸出.
