Crystallization process determines the quality of perovskite films and the performances of resultant perovskite solar cells(PSCs).Dimethylamine oxalate has been proven as a multifunctional modulator,and is explored as an efficient additive in manipulating the crystallization process of CsPbI_(3) perovskite *** one hand,oxalate serves as the precipitator that facilitates the nucleation process of *** larger size of intermediate is conductive to the larger size and smaller grain boundaries of resultant *** the other hand,in subsequent annealing process,the phase conversion and growth process of transient perovskite can be decelerated due to the strong interactions of oxalate with both dimethylamine cation(DMA^(+))and Pb^(2+).Due to the optimized crystallization kinetics,the morphology and quality of CsPbI_(3) perovskite films are comprehensively improved with lower defect concentrations,and charge recombination loss is effectively *** from the optimized crystal quality of perovskite films,the carbon electrode-based CsPbI_(3) PSCs exhibit a champion efficiency of 18.48%.This represents one of the highest levels among all hole transport layer-free inorganic perovskite solar cells.

近年来,全氟及多氟烷基化合物(per-and polyfluoroalkyl substances,PFASs)的大量生产使用,使得其在自然水体中的浓度日益升高.由于PFASs的生物毒性及强稳定性,环境中的PFASs严重威胁到生态环境及人类健康.目前,多个国家及相关国际组织开始对地表水中的PFASs展开检测,但目前的监测基本属于点源监测,大范围、长时间维度的监测依然缺乏,从而无法准确揭示PFASs的时空赋存特征.本文概述了PFASs在地表水中的赋存水平,同时阐述了地表水环境中PFASs的水平分布和垂直分布特征,并揭示了地表水中PFASs污染水平与组成的时间变化规律,总结了影响PFASs污染的主要因素,对后续PFASs监测提出了建议,以期为准确评估水环境中PFASs的污染状况提供依据.

Rice is one of the most important cereal crops in the world,providing food for more than half of the global population;therefore,increasing grain yield is a major goal of rice *** grain yield is largely dependent on grain size,which is specified by its three dimensions(grain length,width,and thickness)and by the degree of grain filling(Xing and Zhang,2010;Fan and Li,2019).Grain size is an important agronomic trait for stable yield,appearance,milling quality,and domestication in rice that is controlled by multiple ***,discovering more genes regulating grain size for understanding the regulatory mechanisms underlying natural variations is important in crop molecular breeding(Zuo and Li,2014).

以欧亚种酿酒葡萄‘小味多’为接穗,分别嫁接‘101-14’、‘5BB’、‘SO4’、‘Beta’和‘1103P’5种砧木,并以‘小味多’自根苗作为对照,采用顶空固相微萃取-气相色谱-质谱联用技术,连续2 a(2016—2017年)分析不同砧穗组合‘小味多’采收期葡萄果实的挥发性物质。结果表明,年份间气候差异是影响‘小味多’葡萄果实香气化合物含量的决定性因素,同时其也受到砧木品种的显著影响。与自根苗‘小味多’相比,5种砧木均显著增加了葡萄果实中C_(6)/C_(9)类物质的含量。砧木‘5BB’显著增加了C_(13)-降异戊二烯类、萜烯类物质的含量;砧木‘1103P’显著增加了结合态羰基化合物类物质的含量;砧木‘101-14’显著增加了游离态羰基化合物类物质的含量,显著降低了结合态C_(13)-降异戊二烯类物质的含量;砧木‘Beta’显著增加了结合态C_(13)-降异戊二烯类、萜烯类物质的含量;砧木‘SO4’显著增加了C_(13)-降异戊二烯类、结合态羰基化合物类、游离态萜烯类物质的含量。正交偏最小二乘判别分析结果表明,(E)-2-己烯醛、(Z)-2-己烯醛、己醛等C_(6)/C_(9)化合物是区分嫁接苗和自根苗的共同差异挥发性化合物。总体而言,在北京地区使用砧木‘5BB’嫁接有利于‘小味多’葡萄采收期果实萜烯类和C_(13)-降异戊二烯类物质的积累。
