A novel advanced oxidation process——wet electrocatalytic oxidation (WEO) was studied with p-nitrophenol as model pollutant and β-PbO2 electrode as the anode. Compared with the effect of the individual wet air oxidation (WAO) and electrochemical oxidation (EO), the effect of WEO showed syn- ergistic effect on COD removal under the conditions of temperature 160℃, C=1000 mg·L-1, PN2=0.50 MPa, PO2=0.9 MPa, current density = 3 mA·cm-2, Na2SO4 3 g·L-1. And the synergistic factor got the best value of 0.98 within 120 min after 180 min treatment. The synergistic factor was studied after 120 min treatment at 100℃, 120℃, 140℃ and 160℃, and the effect of 120℃ was the best with the value of 1.26. Possible mechanism for the synergistic effect was discussed based on the analysis of free-radical generation and intermediates detected by HPLC and GC/MS.

Employing the alkaline water electrolysis system to generate hydrogen holds great prospects but still poses significant challenges,particularly for the construction of hydrogen evolution reaction(HER)catalysts operating at ampere-level current density.Herein,the unique Ru and RuP_(2)dual nano-islands are deliberately implanted on N-doped carbon substrate(denoted as Ru-RuP_(2)/NC),in which a built-in electric field(BEF)is spontaneously generated between Ru-RuP_(2)dual nano-islands driven by their work function difference.Experimental and theoretical results unveil that such constructed BEF could serve as the driving force for triggering fast hydrogen spillover process on bridged Ru-RuP_(2)dual nano-islands,which could invalidate the inhibitory effect of high hydrogen coverage at ampere-level current density,and synchronously speed up the water dissociation on Ru nano-islands and hydrogen adsorption/desorption on RuP_(2)nano-islands through hydrogen spillover process.As a result,the Ru-RuP_(2)/NC affords an ultra-low overpotential of 218 mV to achieve 1.0 A·cm^(−2)along with the superior stability over 1000 h,holding the great promising prospect in practical applications at ampere-level current density.More importantly,this work is the first to advance the scientific understanding of the relationship between the constructed BEF and hydrogen spillover process,which could be enlightening for the rational design of the cost-effective alkaline HER catalysts at ampere-level current density.

Mechanical hill wet-seeded rice machine is beneficial for establishing and growing uniform rows of seedlings.However,there is limited knowledge regarding the effects of the establishment of furrows on growth,lodging and yield,and their relationships with root traits.In this study,field experiments were conducted during 2012 and 2013 using two super rice varieties(hybrid rice Peizataifeng and inbred rice Yuxiangyouzhan)under three furrow establishment treatments(T1,both water and seed furrows were established by the machine;T2,only seed furrows were established by the machine;and T3,neither water nor seed furrows were established by the machine).Lodging index,lodging-related traits,grain yield,above-ground dry weight and root traits were measured.The results showed that the lodging index was significantly affected by the treatments with furrows(T1 and T2).The strongest lodging resistance was detected in the mechanical hill wet-seeded rice with furrow treatment(T1)in both 2012 and 2013.Lodging resistance was strongly related to the breaking resistance.No significant difference was found in grain yield or dry weight of the mechanical hill wet-seeded rice.Therefore,the mechanical hill wet-seeded rice with furrow treatment increased rice lodging resistance,which was related to root traits.

C–Obond activation is a highly efficient,fundamental strategy in the depolymerization and hydrodeoxygenation of chemicals with oxygen-containing functional groups such as oil,coal,and biomass.Developing efficient catalysts for C–Oactivation with ultralow-loading noble and non-noble metals is highly desirable for the improvement of metal atomic utilization.Herein,bimetallic catalysts with atomically dispersed Pt and NiO clusters on different supports were fabricated,and the prepared Pt^(δ+)-NiO/Nb_(2)O_(5)and Pt^(δ+)-NiO/TiO_(2)showed outstanding activity for the hydrogenolysis of benzyl phenyl ether with>99%yield of phenol and toluene due to the excellent cooperation of atomically dispersed Pt and NiO clusters.The synergy mechanism between Pt and Ni and their respective roles in the bimetallic catalyst for C–O hydrogenolysis were clearly clarified.These findings deepen our understanding of the synergy of the two active components and are expected to provide new design concepts for the development of multicomponents catalysts.

陆地卫星 TM数据 (TM6)热波段表示地表热辐射和地表温度变化。长期以来 ,从 TM6数据中演算地表温度通常是通过所谓大气校正法。这一方法需要估计大气热辐射和大气对地表热辐射传导的影响 ,计算过程很复杂 ,误差也较大 ,在实际中应用不多。根据地表热辐射传导方程 ,推导出一个简单易行并且精度较高的演算方法 ,把大气和地表的影响直接包括在演算公式中。该算法需要用地表辐射率、大气透射率和大气平均温度 3个参数进行地表温度的演算。验证表明 ,该方法的地表温度演算较高。当参数估计没有误差时 ,该方法的地表温度演算精度达到 <0 .4℃ ,在参数估计有适度误差时 ,演算精度仍达 <1 .1℃。因该方法适用于仅有一个热波段的遥感数据 ,故称为单窗算法。

面向生物样品三维成像的光干涉显微技术研究进展

第七届新型太阳能电池材料科学与技术学术研讨会

Perovskite solar cells(PSCs) have experienced sharp development and emerged as a superstar in the field of photovoltaics in recent years.We introduces two kinds of dyes,zinc porphyrin(YD2-o-C8) and cis-di(thiocyanato)bis(2,2-bipyridyl4,4-dicarboxylate)ruthenium(II)(denoted as N719) to enable highly efficient and highly stable perovskite solar cells.We find that the YD2-o-C8 molecules with carboxylate groups are able to anchor with under-coordinated Pb defects in the perovskite films which would suppress charge recombination.Moreover,perovskites with YD2-o-C8 form an appropriate energy level alignment which is found to be beneficial for both charge separation and extraction in n–i–p devices.Due to these improvements,the best performing device with YD2-o-C8 shows a PCE of 20.5% with reduced hysteresis,while the unmodified devices show a champion efficiency of 18.5%.For N719,we discovered that the N719 molecules form perovskite-dye complexes in the precursor solution,leading to larger grains and better film crystallinity by slowing down the crystallization process.The presence of N719 molecules in perovskite films greatly retards the formation of perovskite hydrates due to a three-times-increased water migration barrier.Owing to these improvements,no encapsulated N719-PSC retain over 80% of their original efficiencies after aging under a high relative humidity of 60% for 250 h,which is three times longer than that for pristine cells.Above all,cheap and effective routes to improve the efficiency and stability of perovskite solar cells by dyes are represented.

远场光学显微成像是获取待测样品三维结构信息及其动态变化不可或缺的技术。非接触无损害的快速光学三维显微成像技术在生物细胞、生物组织等生物医学成像领域具有独特的应用优势和巨大的应用需求。受限于目前的光电器件只能实现光强的直接探测,光学显微三维成像技术往往通过扫描技术、编码技术或数值算法等将光场的相位等信息转换为光强信息,再通过探测被待测样品调制的光波场强度的变化解析出原始样品的信息,以实现对样品三维形貌、内部结构或折射率分布等多种信息的可视化。利用光波的相干性,结合适当的分波技巧,实现两束光的互干涉或自干涉,将光波场相位信息编码至干涉图样的强度分布中,然后结合适当的算法对干涉图样进行重建,是实现光学三维显微成像的一个重要技术。本文对基于光的干涉,利用干涉条纹的强度提供成像对比度的三维显微成像技术进行综述,阐明了激光照明的数字全息显微、部分相干光照明的数字全息显微、光学相干断层显微和空间非相干光照明的自干涉数字全息显微成像技术的基本原理、成像特性,以及该类技术在样品定量相衬成像、三维层析成像、非扫描快速三维显微成像等领域的应用,同时对该类技术衍生的新技术以及该类技术的未来发展方向进行了详细讨论。
