采用N,N-二甲基甲酰胺(DMF)为极性溶剂溶解醋酸锌(Zn(Ac)_2·2H_2O),然后加入聚丙烯腈(PAN)制得前驱体溶液,采用静电纺丝法制备PAN/Zn(Ac)_2复合纳米纤维膜,将PAN/Zn(Ac)_2复合纳米纤维膜在真空管式炉中经过高温煅烧得到PAN基碳纤维/氧化锌(CF/ZnO)纳米纤维膜,以CF/ZnO纳米纤维膜为光催化剂,亚甲基蓝为污染物,进行光催化降解实验,研究了Zn(Ac)_2含量对PAN/Zn(Ac)_2复合纳米纤维形貌、性能的影响,以及CF/ZnO纳米纤维膜的光催化性能。结果表明:Zn(Ac)_2的掺入并未对PAN的化学结构产生影响,二者属于物理结合,Zn(Ac)_2能较均匀地分布在纤维的内部;随着Zn(Ac)_2含量的增加,CF/ZnO纳米纤维膜对亚甲基蓝的降解率会提高,当Zn(Ac)_2质量分数(相对PAN)为60%时,可见光照射80 min后CF/ZnO纳米纤维膜对亚甲基蓝的降解率达到91.6%。

In order to investigate the mechanism of ROS signaling transduction in after-germination process, we screened a hydrogen peroxide sensitive mutant from EMS mutant library of Arabidopsis thaliana. Hydrogen peroxide sensitive 12（hps12）was screened from this library. Phenotype analysis indicated that hps12 had dwarf plant and shorter pod than wild type（WT）. The cotyledon greening rate of hps12 was decreased after being treated with 4 mmol/L H_2O_2. Furthermore, the isolated leaves of hps12 mutants showed more obvious symptoms of senescence than WT under the treatment of 10 mmol/L H_2O_2. Genetic analysis suggested that hps12 was a monogenic recessive mutant.

传统的中值滤波存在着在有效去掉脉冲噪声的同时也破坏了图像的细节等缺陷,而且运行速度不能很好地满足实时要求。提出了一种基于十字滑动窗口快速自适应中值滤波算法;十字滑动窗口不仅计算速度较方形窗口快,而且充分利用前一窗口信息,通过两个十字相交向量退化和推进,更加快速;还依据噪声强度来调整窗口大小来提高去噪效果。实验证明该算法在去噪的同时能很好地保护图像细节,并使传统中值滤波复杂度由O(D2)降至O(D),速度得到大幅度的提高。

This work reports on a novel BiOI/WO3 composite photoanode, which was fabricated by depositing BiOI onto a WO3 nanoflake electrode through a electrodeposition method. The photoelectrochemical (PEC) activity of the BiOI/WO3 electrode for water splitting under visible-light irradiation was evaluated. The results show that the BiOI/WO3 photoanode achieved a photocurrent density of 1.21 mA·cm–2 at 1.23 V vs. reversible hydrogen electrode (RHE), which was higher than that of the bare WO3 nanoflake electrode (0.67 mA·cm–2). The enhanced PEC acticity of BiOI/WO3 for water splitting can be attributed to the expansion of light absorption range as well as the facilitated separation of photo-generated carriers.
