Environmental and energy problem has always been the biggest challenge in human development. Recently, the development of photocatalysis for the degradation of organic pollutants and the hydrogen evolution has been considered as one of the most promising technology for the dealing with environmental pollution and energy problems in the future. When ＂photocatalytic degrada- tion＂ or ＂photocatalytic and H~ evolution＂ was selected as research topic in Web of Science, during 2012 to 2016 the published papers nurnber of ＂photocatalytic degradation＂ increased fi-om 2702 to 5045 and so was that of ＂photocatalytic and H2 evolution＂ from 346 to 1122.

In recent years,there have been numerous studies on Fenton or Fenton-like reactions mediated by nonfree radicals such as singlet oxygen(1O_(2));however,there are few studies on the synergistic effect of 1O_(2) and free radicals on the degradation of organic molecules,such as phenol in Fenton *** this study,a cocatalyst,CoP,commonly used in photocatalysis was synthesized using a simple two-step method,and a CoP/Fe^(2+)/AM1.5 system was constructed by introducing Fe^(2+)and simulated sunlight(AM1.5)*** newly constructed CoP/Fe^(2+)/AM1.5 system could effectively degrade various organic pollutants,including dyes,phenols,and *** quenching experiments and electron paramagnetic resonance detection confirmed that there were three reactive oxygen species(ROS)in the CoP/Fe^(2+)/AM1.5 system,including·OH_(ads),·O_(2)^(-),and 1O_(2).Further,combined with the liquid chromatogram of phenol,its intermediate products,and the fluorescence diagram of o-hydroxybenzoic acid,it can be concluded that a synergistic effect exists between 1O_(2) and the surface-adsorbed·OH_(ads) in the CoP/Fe^(2+)/AM1.5 *** controllable formation of surface 1O_(2) and·OH_(ads) was achieved through the oxidation(Co^(3+))and reduction(Pδ−)centers exposed on the CoP surface,and the synergistic effect between them results in phenol’s hydroxylation,ring-opening,and *** study of this new mechanism provides a new perspective for revealing the surface interface reaction between ROS and organic pollutants.

Highly divergent SARS-CoV-2 variants have continuously emerged and spread around the world,and updated vaccines and innovative vaccination strategies are urgently needed to address the global SARS-COV2 ***,we established a series of Ad5-vectored SARS-CoV-2 variant vaccines encoding multiple spike proteins derived from the Alpha,Beta,Gamma,Epsilon,Kappa,Delta and Omicron lineages and analyzed the antibody immune responses induced by single-dose and prime-boost vaccination strategies against emerging SARS-CoV-2 variants of concern(VOCs).Single-dose vaccination with SARS-CoV-2 variant vaccines tended to elicit the optimal self-matched neutralizing effects,and Ad5-B.1.351 produced more broad-spectrum cross-neutralizing antibodies against diverse *** contrast,prime-boost vaccination further strengthened and broadened the neutralizing antibody responses against highly divergent SARS-CoV-2 *** heterologous administration of Ad5-B.1.617.2 and Ad5-B.1.429 to Ad5-WT-primed mice resulted in superior antibody responses against most *** particular,the Omicron spike could only stimulate self-matched neutralizing antibodies with infrequent cross-reactivities to other variants used in single-dose vaccination strategies;moreover,with prime-boost regimens,this vaccine elicited an optimal specific neutralizing antibody response to Omicron,and prompted cross-antibody responses against other VOCs that were very similar to those obtained with Ad5-WT ***,this study delineated the unique characteristics of antibody responses to the SARS-CoV-2 VOC spikes with the single-dose or prime-boost vaccination strategies and provided insight into the vaccine development of next SARS-CoV-2 VOCs.

为探究苏云金芽胞杆菌G033A(Bt G033A)对番茄潜叶蛾不同龄期幼虫的毒力大小及对赤眼蜂寄生番茄潜叶蛾能力的影响,本研究采用浸叶法和饲料混毒法分别对番茄潜叶蛾及三种赤眼蜂进行处理,测定了Bt G033A对番茄潜叶蛾不同龄期幼虫和三种赤眼蜂成虫的室内毒力,同时分析Bt G033A对三种赤眼蜂寄生量及功能反应的影响.结果表明,Bt G033A对番茄潜叶蛾 1龄幼虫、2龄幼虫、3龄幼虫、4 龄幼虫的LC50分别为 25.381、19.537、17.406 和 15.772 g/L,而对三种赤眼蜂均为低毒.在Bt G033A田间推荐浓度处理后,虽然玉米螟赤眼蜂、螟黄赤眼蜂、松毛虫赤眼蜂对番茄潜叶蛾卵的寄生功能反应模型仍符合Holling Ⅱ型,但三种赤眼蜂的寄生能力均有所降低.其中,玉米螟赤眼蜂在药剂对照组的寄生量(25粒/皿:18.600 粒)、处理猎物时间(0.012 d)、控害效能(84.833)、日寄生上限(83.333 粒)和搜寻效应均表明其对番茄潜叶蛾的寄生能力强于螟黄赤眼蜂和松毛虫赤眼蜂.此外,在药剂处理后,玉米螟赤眼蜂各项寄生参数同样优于其他两种赤眼蜂.因此,玉米螟赤眼蜂可作为番茄潜叶蛾的优选寄生性天敌之一,并可联合Bt G033A对番茄潜叶蛾进行协同防控.
