| 1 | Lysozyme inhibits postharvest physiological deterioration of cassava显示文摘After harvest,cassava(Manihot esculenta Crantz)storage roots undergo rapid postharvest physiological deterioration,producing blue-brown discoloration in the vasculature due to the production of polyphenolics(mainly quinonesand coumarins)by enzymes such as polyphenol oxidase(PPO).Here,we report the application of hen egg-white lysozyme(HEWL),a natural PPO inhibitor,in transgenic cassava to repress the symptoms of postharvest physiological deterioration.The HEWL-expressing transgenic plants had lower levels of the two main cassava coumarins tested,scopoletin and scopolin,compared with wild type.HEWL-expressing cassava also showed increased tolerance of oxidative stress.Overall,the lysozyme-PPO system proved to be functional in plants for repressing PPO-mediated commercial product browning. | Xiaoyun Wu Jia Xu Qiuxiang Ma Sulaiman Ahmed Xinlu Lu Erjun Ling Peng Zhang | 2022 | Journal of Integrative Plant Biology2022，64，3： | 1 |

| 3 | The first application of isoindigo-based polymers in non-fullerene organic solar cells显示文摘Although isoindigo(IID)-based polymers can realize high charge mobility,these materials are currently confined to fullerenebased organic solar cells(OSCs).Herein,we designed a pair of alternative D-π-A type copolymers,PE71 and PE72,to expand the application in non-fullerene OSCs,where benzo[1,2-b:4,5-b′]thiophene(BDT),thieno[3,2-b]thiophene(TT)and IID units were used as D,A andπ-bridge,respectively.The aim of optimizing the length of alkyl chains on TT bridge is to ensure polymer solubility,crystallinity as well as miscibility with acceptor molecules.We find that PE71 and PE72 exhibit similar optical and electronic properties,but PE71 with shorter hexyl chain tends to aggregate into fiber-like structure.In the end,Y6 is selected as the electron acceptor because of suitable energy levels and complementary absorption spectrum.Finally,PE71:Y6 device realizes a power conversion efficiency(PCE)of 12.03%,which is obviously higher than that of PE72:Y6 device(9.74%)and is also the highest value for IID-based photovoltaic polymers.The charge transport,molecular aggregation,film morphology and energy loss analysis were systematically investigated.The improved photovoltaic performance of PE71:Y6 mainly originates from the better interpenetrating network structure toward facilitating exciton seperation and free charge carrier transportation.Our results indicate that IID-based D-π-A polymers can also be utilized in non-fullerene OSCs and the alkyl chains on the thieno[3,2-b]thiopheneπ-bridge have a vital effect on the photovoltaic performance. | Bao Zhang Ning An Hongbo Wu Yanfang Geng Yanming Sun Zaifei Ma Weiwei Li Qiang Guo Erjun Zhou | 2020 | Science China Chemistry2020，63，9： | 1 |

| 8 | High-density triple-phase contact points for enhanced photocatalytic CO_(2) reduction to methanol显示文摘The efficiency of photocatalytic CO_(2) reduction reaction(PCRR)is restricted by the low solubility and mobility of CO_(2) in water,poor CO_(2) adsorption capacity of catalyst,and competition with hydrogen evolution reaction(HER).Recently,hydrophobic modification of the catalyst surface has been proposed as a potential solution to induce the formation of triple-phase contact points(TPCPs)of CO_(2)(gas phase),H_(2) O(liquid phase),and catalysts(solid phase)near the surface of the catalyst,enabling direct delivery of highly concentrated CO_(2) molecules to the active reaction sites,resulting in higher CO_(2) and lower H+surface concentrations.The TPCPs thus act as the ideal reaction points with enhanced PCRR and suppressed HER.However,the initial synthesis of triple-phase photocatalysts tends to possess a lower bulk density of TPCPs due to the simple structure leading to limited active points and CO_(2) adsorption sites.Here,based on constructing a hydrophobic hierarchical porous TiO_(2)(o-HPT)with interconnected macropores and mesopores structure,we have significantly increased the density of TPCPs in a unit volume of the photocatalyst.Compared with hydrophobic macroporous TiO_(2)(o-MacPT)or mesoporous TiO_(2)(o-MesPT),the o-HPT with increased TPCP density leads to enhanced photoactivity,enabling a high methanol production rate with 1111.5μmol g^(−1) h^(−1) from PCRR.These results emphasize the significance of high-density TPCPs design and propose a potential path for developing efficient PCRR systems. | Hanwen Jian Kaiming Deng Tongyu Wang Chengxi Huang Fang Wu Hailing Huo Bo Ouyang Xuan Liu Jingjing Ma Erjun Kan Ang Li | 2024 | Chinese Chemical Letters2024，35，2： | 0 |
| 9 | Engineering Vacancy-Atom Ensembles to Boost Catalytic Activity toward Hydrogen Evolution显示文摘The dissociation of water is the rate-determining step of several energy-relating reactions due to high energy barrier in homolysis of H-O bond.Herein,engineering vacancy-atom ensembles via injecting oxygen vacancy(V O)into single facet-exposed TiO_(2)-Pd catalyst to form V_(O)-Pd ensemble is proposed and implemented.The outstanding activity of as-prepared catalyst,1.5-PdTV_(O),toward water dissociation is established with a turnover frequency of 240 min^(−1) in ammonia borane hydrolysis at 298 K.Density functional theory simulation suggests that the V_(O)-Pd ensemble is responsible for the high intrinsic catalytic activity.Water molecules tend to be dissociated on V_(O) sites and ammonia borane molecules on Pd atoms.Those H atoms from water dissociation on V_(O) combine with H atoms from ammonia borane on Pd atoms to generate H_(2).This insights into engineering vacancy-atom ensembles catalysis provide a new avenue to design catalytic materials for important energy chemical reactions. | Ruofan Shen Yanyan Liu Hao Wen Xianli Wu Zhikun Peng Sehrish Mehdi Tao Liu Huanhuan Zhang Shuyan Guan Erjun Liang Baojun Li | 2023 | Energy & Environmental Materials2023，6，1： | 0 |
| 10 | Enhanced charge separation by continuous homojunction with spatially separated redox sites for hydrogen evolution显示文摘Photocatalytic hydrogen generation represents a promising strategy for the establishment of a sustainable and environmentally friendly energy reservoir.However,the current solar-to-hydrogen conversion efficiency is not yet sufficient for practical hydrogen production,highlighting the need for further research and development.Here,we report the synthesis of a Sn-doped TiO_(2)continuous homojunction hollow sphere,achieved through controlled calcination time.The incorporation of a gradient doping profile has been demonstrated to generate a gradient in the band edge energy,facilitating carrier orientation migration.Furthermore,the hollow sphere’s outer and inner sides provide spatially separated reaction sites allowing for the separate acceptance of holes and electrons,which enables the rapid utilization of carriers after separation.As a result,the hollow sphere TiO_(2)with gradient Sn doping exhibits a significantly increased hydrogen production rate of 20.1 mmol·g^(−1)·h^(−1).This study offers a compelling and effective approach to the designing and fabricating highly efficient nanostructured photocatalysts for solar energy conversion applications. | Mingyuan Yu Tongyu Wang Chengxi Huang Fang Wu Xuan Liu Hailing Huo Hanwen Jian Zikun Liang Jingjing Ma Erjun Kan Ang Li | 2023 | Nano Research2023，16，10： | 0 |
