| 1 | Low-cost and high safe manganese-based aqueous battery for grid energy storage and conversion显示文摘As an effective energy storage technology, rechargeable batteries have long been considered as a promising solution for grid integration of intermittent renewables(such as solar and wind energy). However,their wide application is still limited by safety issue and high cost. Herein, a new battery chemistry is proposed to satisfy the requirements of grid energy storage. We report a simple Cu-Mn battery, which is composed of two separated current collectors in an H2SO4-CuSO4-MnSO4 electrolyte without using any membrane. The Cu-Mn battery shows an energy density of 40.8 Wh L-1, a super-long life of 10,000 cycles(without obvious capacity decay) and negligible self-discharge. And the capital cost of US$ 11.9 kWh-1 based on electrolyte is lower than any previous batteries. More importantly, the battery can still work smoothly during thermal abuse test and drill-through test, showing high safe nature. Furthermore, a combination system integrating the Cu-Mn battery and hydrogen evolution is also proposed, which is able to avoid the generation of explosive H2/O2 mixture, and presents an efficient approach for grid energy storage and conversion. | Jianhang Huang Zhaowei Guo Xiaoli Dong Duan Bin Yonggang Wang Yongyao Xia | 2019 | Science Bulletin2019，64，23： | 4 |
| 2 | Review on mechanisms and structure-activity relationship of hypoglycemic effects of polysaccharides from natural resources显示文摘Diabetes mellitus(DM)is a common multifactorial disease,causing various complications,such as chronic metabolism.The current therapies for diabetes mellitus are commercial diabetic drugs that have different definite side effect.However,polysaccharides mainly extracted from natural resources,have advantages of safety,accessibility,and anti-diabetic potential.We have summarized recent research of natural polysaccharides with hypoglycemic activities,focusing on different pharmacological mechanisms in various cell and animal models.The relationships of structure-hypoglycemic effect are also discussed in detail.This review could provide a comprehensive perspective for better understanding on development and mechanism of natural polysaccharides against diabetes mellitus,which have been required by clinical studies yet. | Xiaolong Ji Jianhang Guo Tengzheng Cao Tingting Zhang Yanqi Liu Yizhe Yan | 2023 | Food Science and Human Wellness2023，12，6： | 2 |
| 3 | In-situ/operando characterization techniques for organic semiconductors and devices显示文摘The increasing demands of multifunctional organic electronics require advanced organic semiconducting materials to be developed and significant improvements to be made to device performance. Thus, it is necessary to gain an in-depth understanding of the film growth process, electronic states, and dynamic structure-property relationship under realistic operation conditions, which can be obtained by in-situ/operando characterization techniques for organic devices. Here, the up-todate developments in the in-situ/operando optical, scanning probe microscopy, and spectroscopy techniques that are employed for studies of film morphological evolution, crystal structures, semiconductor-electrolyte interface properties, and charge carrier dynamics are described and summarized. These advanced technologies leverage the traditional static characterizations into an in-situ and interactive manipulation of organic semiconducting films and devices without sacrificing the resolution, which facilitates the exploration of the intrinsic structure-property relationship of organic materials and the optimization of organic devices for advanced applications. | Sai Jiang Qinyong Dai Jianhang Guo Yun Li | 2022 | Journal of Semiconductors2022，43，4： | 1 |

| 5 | Engineering plants to secrete affinity-tagged pathogen elicitors for deciphering immune receptor complex or inducing enhanced immunity显示文摘Plant cells mount plenty of pattern-recognition receptors(PRRs)to detect the microbe-associated molecular patterns(MAMPs)from potential microbial pathogens.MAMPs are overrepresented by proteinaneous patterns,such as the flg22 peptide from bacterial flagellin.Identification of PRR receptor complex components by forward or reverse genetics can be time/labor-consuming,and be confounded by functional redundancies.Here,we present a strategy for identifying PRR complex components by engineering plants to inducibly secrete affinity-tagged proteinaneous MAMPs to the apoplast.The PRR protein complexes bound to self-secreted MAMPs are enriched through affinity purification and dissected by mass spectrometry.As a proof of principle,we could capture the flg22 receptor FLS2 and co-receptor BAK1 using Arabidopsis plants secreting FLAG-tagged flg22 under estradiolinduction.Moreover,we identified receptor-like kinases LIK1 and PEPR1/PEPR2 as potential components in the FLS2 receptor complex,which were further validated by protein–protein interaction assays and the reverse genetics approach.Our study showcases a simple way to biochemically identify endogenous PRR complex components without overexpressing the PRR or using chemical crosslinkers,and suggests a possible crosstalk between different immune receptors in plants.A modest dose of estradiol can also be applied to inducing enhanced immunity in engineered plants to both bacterial and fungal pathogens. | Shuang Miao Jiuer Liu Jianhang Guo Jian-Feng Li | 2020 | Journal of Integrative Plant Biology2020，62，6： | 0 |
| 6 | A Smarter Pavlovian Dog with Optically Modulated Associative Learning in an Organic Ferroelectric Neuromem显示文摘Associative learning is a critical learning principle uniting discrete ideas and percepts to improve individuals’adaptability.However,enabling high tunability of the association processes as in biological counterparts and thus integration of multiple signals from the environment,ideally in a single device,is challenging.Here,we fabricate an organic ferroelectric neuromem capable of monadically implementing optically modulated associative learning.This approach couples the photogating effect at the interface with ferroelectric polarization switching,enabling highly tunable optical modulation of charge carriers.Our device acts as a smarter Pavlovian dog exhibiting adjustable associative learning with the training cycles tuned from thirteen to two.In particular,we obtain a large output difference(>10^(3)),which is very similar to the all-or-nothing biological sensory/motor neuron spiking with decrementless conduction.As proof-of-concept demonstrations,photoferroelectric coupling-based applications in cryptography and logic gates are achieved in a single device,indicating compatibility with biological and digital data processing. | Mengjiao Pei Changjin Wan Qiong Chang Jianhang Guo Sai Jiang Bowen Zhang Xinran Wang Yi Shi Yun Li | 2022 | Research2022，，1： | 0 |
| 7 | Large-Area Monolayer n-Type Molecular Semiconductors with Improved Thermal Stability and Charge Injection显示文摘We fabricated monolayer n-type two-dimensional crystalline semiconducting films with millimeter-sized areas and remarkable morphological uniformity using an antisolvent-confined spin-coating method.The antisolvent can cause a downstream Marangoni flow,which improves the film morphologies.The deposited crystalline monolayer films exhibit excellent thermal stabilities after annealing,which reveals the annealing-induced enhancement of crystallinity.The transistors based on the n-type monolayer crystalline films show linear output characteristics and superior electron mobilities.The improved charge injection between monolayer films and Au electrodes results from the energy level shift as the films decrease to the monolayer,which leads to a lower injection barrier.This work demonstrates a promising method for fabricating air-stable,low-cost,high-performance,and large-area organic electronics. | Sai Jiang Lichao Peng Xiaosong Du Qinyong Dai Jianhang Guo Jianhui Gu Jian Su Ding Gu Qijing Wang Huafei Guo Jianhua Qiu Yun Li | 2023 | Chinese Physics Letters2023，40，3： | 0 |
