| 1 | Different B-Type Methionine Sulfoxide Reductases in Chlamydomonas May Protect the Alga against High-Light, Sulfur-Depletion, or Oxidative Stress显示文摘The genome of unicellular green alga Chlamydomonas reinhardtii contains four genes encoding B-type methionine sulfoxide reductases,MSRB1.1,MSRB1.2,MSRB2.1,and MSRB2.2,with functions largely unknown.To understand the cell defense system mediated by the methionine sulfoxide reductases in Chlamydomonas,we analyzed expression and physiological roles of the MSRBs under different abiotic stress conditions using immunoblotting and quantitative polymerase chain reaction(PCR)analyses.We showed that the MSRB2.2 protein was accumulated in cells treated with high light(1,300 mE/m2per s),whereas MSRB1.1 was accumulated in the cells under 1 mmol/L H2O2treatment or sulfur depletion.We observed that the cells with the MSRB2.2 knockdown and overexpression displayed increased and decreased sensitivity to high light,respectively,based on in situ chlorophyll a fuorescence measures.We also observed that the cells with the MSRB1.1 knockdown and overexpression displayed decreased and increased tolerance to sulfur-depletion and oxidative stresses,respectively,based on growth and H2-producing performance.The physiological implications revealed from the experimental data highlight the importance of MSRB2.2 and MSRB1.1 in protecting Chlamydomonas cells against adverse conditions such as high-light,sulfur-depletion,and oxidative stresses. | Lei Zhao Mei Chen Dongmei Cheng Haomeng Yang Yongle Sun Heyi Zhou Fang Huang | 2013 | Journal of Integrative Plant Biology2013，55，11： | 2 |
| 2 | Recent progress on three-dimensional nanoarchitecture anode materials for lithium/sodium storage显示文摘High-performance batteries with high density and low cost are needed for the development of largescale energy storage fields such as electric vehicles and renewable energy systems.The anode with threedimensional(3D)nanoarchitecture is one of the most attractive candidates for high-performance lithiumion batteries(LIBs)and sodium-ion batteries(SIBs)due to its efficient electron/ion transport and high active material mass loading.Although some important breakthroughs have been made in 3D nanoarchitecture anode materials,more improvements are still needed for high cycling stability and high energy density.Herein,the latest research progress of 3D nanoarchitecture anode materials for LIBs and SIBs is reviewed,including nanoporous metal,nanoporous graphene,and their derived foams.Specifically,the storage properties of Li/Na ions,the kinetics of ion/electron transport,and specific chemical interactions are discussed based on the structure design.In addition,the research strategies and structural characteristics of 3D nanoarchitecture anode materials are summarized,providing a reference for the further development of LIBs and SIBs.Meanwhile,the future research directions of LIBs and SIBs have also prospected. | Zhijia Zhang Yuefang Chen Shihao Sun Kai Sun Heyi Sun Hongwei Li Yuhe Yang Mengmeng Zhang Weijie Li Shulei Chou Huakun Liu Yong Jiang | 2022 | Journal of Materials Science & Technology2022，，24： | 2 |

| 5 | Host-Guest Strategy Enabling Nonhalogenated Solvent Processing for High-Performance All-Polymer Hosted Solar Cells显示文摘The power conversion efficiencies(PCEs)of all-polymer solar cells(all-PSCs),usually processed from low-boiling-point and toxic sol-vents,have reached high values of 18%.However,poor miscibility and uncontrollable crystallinity in polymer blends lead to a nota-ble drop in the PCEs when using green solvents,limiting the practical development of all-PSCs.Herein,a third component(guest)BTO was employed to optimize the miscibility and enhance the crystallinity of PM6/PY2Se-F host film processed from green solvent toluene(TL),which can effectively suppress the excessive aggregation of PY2Se-F and facilitate a nano-scale interpenetrating net-work morphology for exciton dissociation and charge transport.As a result,TL-processed all-polymer hosted solar cells(all-PHSCs)exhibited an impressive PCE of 17.01%.Moreover,the strong molecular interaction between the host and guest molecules also en-hances the thermal stability of the devices.Our host-guest strategy provides a unique approach to developing high-efficiency and stable all-PHSCs processed from green solvents,paving the way for the industrial development of all-PHSCs. | Yuting Huang Haiyang Chen Qunping Fan Ziyuan Chen Junyuan Ding Heyi Yang Zhe Sun Rui Zhang Weijie Chen Changduk Yang Feng Gao Yaowen Li | 2023 | Chinese Journal of Chemistry2023，41，9： | 0 |
| 6 | Host-Guest Active Layer Enabling Annealing-Free,Nonhalogenated Green Solvent Processing for High-Performance Organic Solar Cells显示文摘Recent advances in non-fullerene acceptors(NFAs)like Y6 have pushed the power conversion efficiencies(PCEs)of organic solar cells(OSCs)above 19%.However,the harsh fabrication conditions,such as the use of the highly volatile chloroform(CF)solvent and the thermal annealing process,are not suitable for large-area printing technologies and environmental standards.Here,a series of guest molecules,BT2O,BTO,and BT4O,are designed and synthesized with different numbers of oligo ethylene glycol(OEG)repeating units in side chains.All these guest molecules could tune the crystallization kinetics of the annealing-free host-guest active layers by inducing the self-assembly of Y6 in non-halogenated paraxylene(PX)solution.The increasing number of OEG repeating units in guest molecules could enhance the molecular assembly ability but molecular stacking steric hindrance simultaneously.Therefore,BTO with three OEG repeating units blended with PM6:PM7:Y6 delivers the highest PCE of 17.78%.Our results demonstrate controlling the crystallization kinetics via delicate side-chain engineering of guest molecules is an effective way to achieve efficient OSCs in non-halogenated solution. | Weiwei Sun Haiyang Chen Ben Zhang Qinrong Cheng Heyi Yang Ziyuan Chen Guang Zeng Junyuan Ding Weijie Chen Yaowen Li | 2022 | Chinese Journal of Chemistry2022，40，24： | 0 |
