| 1 | A Simple Approach to Bioconjugation at Diverse Levels: Metal-Free Click Reactions of Activated Alkynes with Native Groups of Biotargets without Prefunctionalization显示文摘Te efcient bioconjugation of functional groups/molecules to targeted matrix and bio-related species drives the great development of material science and biomedicine,while the dilemma of metal catalysis,uneasy premodifcation,and limited reaction efciency in traditional bioconjugation has restricted the booming development to some extent.Here,we provide a strategy for metal-free click bioconjugation at diverse levels based on activated alkynes.As a proof-of-concept,the abundant native groups including amine,thiol,and hydroxyl groups can directly react with activated alkynes without any modifcation in the absence of metal catalysis.Trough this strategy,high-efcient modifcation and potential functionalization can be achieved for natural polysaccharide,biocompatible polyethylene glycol(PEG),synthetic polymers,cell penetrating peptide,protein,fast whole-cell mapping,and even quick diferentiation and staining of Gram-positive bacteria,etc.Terefore,current metal-free click bioconjugation strategy based on activated alkynes is promising for the development of quick fuorescence labeling and functional modifcation of many targets and can be widely applied towards the fabrication of complex biomaterials and future in vivo labeling and detection. | Xianglong Hu Xueqian Zhao Benzhao He Zheng Zhao Zheng Zheng Pengfei Zhang Xiujuan Shi Ryan T.K.Kwok Jacky W.Y.Lam Anjun Qin Ben Zhong Tang | 2018 | Research2018，，1： | 7 |
| 2 | A specific aggregation-induced emission-conjugated polymer enables visual monitoring of osteogenic differentiation显示文摘Osteogenic differentiation is the basis of bone growth and repair related to many diseases,in which evaluating the degree and ability of osteogenic transformation is quite important and highly desirable.However,fixing or stopping the growth of cells is required for conventional methods to monitor osteogenic differentiation,which cannot realize the full investigation of the dynamic process.Herein,a new anion conjugated polymer featuring aggregation-induced emission(AIE)characteristics is developed with excellent solubility for in-situ monitoring the process of osteogenic differentiation.This novel polymer can bind with osteogenic differentiated cells,and the intracellular fluorescence increases gradually with the enhancement of osteogenic differentiation.Moreover,it possesses good biosafety with negligible effect on cell activity and osteogenic differentiation,which cannot be realized by the typical method of Alizarin Red S staining.Further study shows that the polymer crosses the cell membrane through endocytosis and enriches in lysosomes,whereas no obvious fluorescence is detected with other cells,including non-differentiated osteoblast cells,under the same conditions,demonstrating the high selectivity.This is the first fluorescent probe with excellent specificity to realize real-time observation of the process of osteogenic differentiation.Therefore,PTB-EDTA shows great promise in the study of osteogenic differentiation and related applications. | Zhenyu Zheng Taotao Zhou Rong Hu Minjun Huang Xiang Ao Jun Chu Tao Jiang Anjun Qin Zhongmin Zhang | 2020 | Bioactive Materials2020，5，4： | 3 |
| 3 | Modulating Sand’s time by ion-transport-enhancement toward dendrite-free lithium metal anode显示文摘Metallic lithium is deemed as the“Holy Grail”anode in high-energy-density secondary batteries.Uncontrollable lithium dendrite growth and related issues originated from uneven concentration distribution of Li+in the vicinity of the anode,however,induce severe safety concerns and poor cycling efficiency,dragging lithium metal anode out of practical application.Herein we address these issues by using cross-linked lithiophilic amino phosphonic acid resin as the effective host with the ion-transportenhancement feature.Based on theoretical calculations and multiphysics simulation,it is found that this ion-transportenhancement feature is capable of facilitating the self-concentration kinetics of Li+and accelerating Li^(+)transfer at the electrolyte/electrode interface,leading to uniform bulk lithium deposition.Experimental results show that the proposed lithiumhosting resin decreases the irreversible lithium capacity and improves lithium utilization(with the Coulombic efficiency(CE)of 98.8%over 130 cycles).Our work demonstrates that inducing the self-concentrating distribution of Li+at the interface can be an effective strategy for improving the interfacial ion concentration gradient and optimizing lithium deposition,which opens a new avenue for the practical development of next-generation lithium metal batteries. | Yu Yan Chaozhu Shu Ruixin Zheng Minglu Li Zhiqun Ran Miao He Anjun Hu Ting Zeng Haoyang Xu Ying Zeng | 2022 | Nano Research2022，15，4： | 2 |
| 4 | Self-healing hyperbranched polytriazoles prepared by metal-free click polymerization of propiolate and azide monomers显示文摘The last decade has witnessed the quick develop of self-healing materials. As a newborn strategy, the alternative of irreversible covalent bond formation is, however, to be further developed. In this paper, self-healing hyperbranched poly(aroxycarbonyltriazole)based on such mechanism were prepared by our developed metal-free click polymerization of simplified dipropiolate and triazide. Thanks to their excellent processability and film-forming ability, high quality homogeneous films free from defects were obtained by casting. The cut films could be healed by stacking or pressing the halves together at room temperature and elevated temperature. Thus, this design concept for self-healing materials should be generally applicable to other hyperbranched polymers with reactive groups on their peripheries. | Xin Wang Rongrong Hu Zujin Zhao Anjun Qin Ben Zhong Tang | 2016 | Science China Chemistry2016，59，12： | 1 |
| 5 | Lab-in-cell based on spontaneous amino-yne click polymerization显示文摘Unnatural reaction in the living cells is a powerful tool for biological research. However, the polymerization inside cells is rarely reported. In this work, a lab-in-cell is illustrated based on our developed spontaneous amino-yne click polymerization. Carbonyl group activated terminal diyne can spontaneously polymerize with tetraphenylethene(TPE)-containing primary diamine inside cells, and polymer with weight-average molecular weight of 7,300 was yielded. By utilizing this in vivo amino-yne click polymerization and taking advantage of the aggregation-induced emission feature of TPE, a 'turn-on' cell imaging was realized,and in-situ killing of cells was also acquired by destroying the structures of actin and tubulin, which cannot be realized by preprepared polymer. This strategy provides a useful platform and holds great promise in biochemistry and therapy applications. | Rong Hu Xu Chen Taotao Zhou Han Si Benzhao He Ryan T. K.

| 6 | Active site synergy of the mixed-phase cobalt diselenides with slight lattice distortion for highly reversible and stable lithium oxygen batteries显示文摘Many non-precious metal-based catalysts with high intrinsic activity for catalytic reactions are prone to structural degradation in practical application,which leads to poor stability.In this work,we propose c-CoSe_(2)/o-CoSe_(2)as the oxygen electrode of lithium-oxygen batteries(LOBs)to improve its cycle stability.The heterogeneous interface inside c-CoSe_(2)/o-CoSe_(2)leads to an increase in the covalence bonds between Co and Se ions,which greatly enhances the robustness of the crystal lattice,thereby improving the stability of the catalyst.In addition,the strong interaction between the mixed phases is favorable for adjusting the electron density around the active sites and boosting oxygen electrode kinetics.Moreover,the epitaxial growth of o-CoSe_(2)on c-CoSe_(2)will cause abundant heterogeneous interfaces and slight lattice distortion along the interfaces,thereby providing sufficient catalytic reaction sites.The DFT calculation results show that the optimized adsorption of intermediates at the heterogeneous interface plays an important role in boosting oxygen electrode reactions and improving the electrochemical performance of LOBs.The experimental results show that LOBs with the c-CoSe_(2)/o-CoSe_(2)electrodes exhibit outstanding performance,including large specific capacity of about 23,878 m A h g^(-1),high coulombic efficiency of up to 93.66%,and excellent stability of over 176 cycles(1410 h). | Minglu Li Chaozhu Shu Anjun Hu Yu Yan Miao He Jianping Long | 2021 | Journal of Materials Science & Technology2021，，33： | 1 |

| 9 | Visualized Degradation of CO_(2)-Based Unsaturated Polyesters toward Structure-Controlled and High-Value-Added Fluorophores显示文摘In comparing with traditional polymer degradation toward unknown or unvalued products(i.e.,downcycling),new methods to degrade polymers into monomers or high-value-added materials(i.e.,upcycling)are preferable for sustainable developments.In this work,CO_(2)-based linear and cross-linked unsaturated polyesters,that is,poly(alkynoate)s,were successfully degraded by benzamidine into diols and high-value-added pyrimidone or imidazolone derivatives through controlled reaction conditions.The degradation process could be visualized under UV light via gradually increased luminescent intensity of the reaction mixtures and fluorescence patterns could be generated through microcontact printing of the stamp on the thin films of poly(alkynoate)s.Moreover,the pyrimidone derivatives could be applied in bioimaging and inhibiting bacteria,and the imidazolone derivatives could be used for the detection and recovery of gold(III)ions from electronic waste and serve as the fluorescent sensor to detect in situ-generated amines from food spoilage.Thus,this work presents a visualized and high value productselective degradation to solve the end-of-life issue of polymers. | Bo Song Tianwen Bai Dongming Liu Rong Hu Dan Lu Anjun Qin Jun Ling Ben Zhong Tang | 2022 | CCS Chemistry2022，4，1： | 1 |

| 11 | Challenges and advances on low-temperature rechargeable lithiumsulfur batteries显示文摘Lithium-sulfur(Li-S)batteries have demonstrated the potential to conquer the energy storage related market due to the extremely high energy density.However,their performances at low temperature are still needed to be improved to broaden their applications.Therefore,in this review,the basic failure mechanisms and major challenges of Li-S battery at low temperature are categorized as the high desolvation barrier of Li^(+),uncontrolled nucleation and deposition of lithium,polysulfides clustering,and passivation of cathode by film like Li_(2)S.Targeting these major issues,strategies,and advances concerning the design of optimized electrolyte,composite cathode and functional separator are highlighted and discussed.Finally,the suggestions are proposed for the future development of practical Li-S battery working at low temperature scenarios,hoping to accelerate the commercialization process and bring revolution to the energy storage market. | Yu Jiao Fan Wang Yuhong Ma Sangang Luo Yaoyao Li Anjun Hu Miao He Fei Li Dongjiang Chen Wei Chen Tianyu Lei Yin Hu | 2023 | Nano Research2023，16，6： | 0 |
| 12 | Synergy of in-situ heterogeneous interphases tailored lithium deposition显示文摘The implementation of a robust artificial solid electrolyte interphase(ASEI)to replace the unstable natural SEI can regulate lithium deposition behaviors and avoid the safety hazards caused by dendrites permeation in lithium metal batteries.Despite of devoted efforts in tailoring components of ASEI,the intrinsic mechanism of interfacial synergy within the heterogeneous interphases has not been well elucidated yet.Herein,we show that the lithium plating/striping behaviors can be substantially enhanced(over 900 h with an overpotential of less than 20 mV at 1 mA·cm^(−2)in Li|Li symmetric cells and 146 cycles in anode-free cells)by regulating the heterogeneous interphases.This favorable ASEI composed of LiF and Li_(3)N components can be in-situ generated during cycling by large-scale fabricated fluorinated boron nitride coatings.Further,the synergy of each heterogeneous component within ASEI was explored theoretically and experimentally.Li_(3)N has high adsorption energy and low ion diffusion barrier,which facilitates the transport of lithium ions and avoids its local accumulation to evolve into dendrites.Both the substrate and LiF are interfacially stable with high electron tunneling barriers,preventing the electrolyte decomposition and parasitic reactions.Finally,the high stiffness of the boron nitride also ensures lithium dendrites are suppressed once they grow,providing a stable environment for long-term cycling of lithium metal batteries. | Yinuo Li Anjun Hu Xingdong Gan Miao He Jun Zhu Wei Chen Yin Hu Tianyu Lei Fei Li Yaoyao Li Yuxin Fan Fan Wang Mingjie Zhou An Wen Baihai Li | 2023 | Nano Research2023，16，6： | 0 |
| 13 | Red fluorescent siloles with aggregation-enhanced emission characteristics显示文摘Aseries of new red fluorescent siloles consisting of a silole core and dimesitylboranyl substituent connected with a furan,thiophene,and selenophene bridges were synthesized and characterized.The optical properties,electronic structures,and electroluminescence (EL) performances were investigated.The emission wavelengths were red-shifted from the siloles with furan,to those with thiophene,and then selenophene.The thiophene,and selenophene-containing siloles,(MesB)_2DTTPS,and(MesB)_2DSTPS,showed the typical aggregation-enhanced emission (AEE) feature,while furan-containingone,(MesB)_2DFTPS,showed slight emission decrease as the aggregate formation.Theoretical calculations were carried out to explain the difference in the optical properties.Undoped OLEDs using these red siloles as light-emitting layers were fabricated.The device of (MesB)_2DTTPS exhibited the bestper formance.It radiated red ELemission at 589 nm,and afforded good maximum luminance,current,power,and external quantum efficiency of13300cdm^(-2),4.3cd A^(-1),2.9 lmW^(-1),and1.8%,respectively. | Bin Chen Han Nie Rongrong Hu Anjun Qin Zujin Zhao Ben-Zhong Tang | 2016 | Science China Chemistry2016，59，6： | 0 |
| 14 | The commercial antibiotics with inherent AIE feature: In situ visualization of antibiotic metabolism and specifically differentiation of bacterial species and broad-spectrum therapy显示文摘The research on pharmacology usually focuses on the structure-activity relationships of drugs,such as antibiotics,to enhance their activity,but often ignores their optical properties.However,investigating the photophysical properties of drugs is of great significance because they could be used to in situ visualize their positions and help us to understand their working metabolism.In this work,we identified a class of commercialized antibiotics,such as levofloxacin,norfloxacin,and moxifloxacin(MXF)hydrochloride,featuring the unique aggregation-induced emission(AIE)characteristics.By taking advantage of their AIE feature,antibiotic metabolism in cells could be in situ visualized,which clearly shows that the luminescent aggregates accumulate in the lysosomes.Moreover,after a structure-activity relationship study,we found an ideal site of MXF to be modified with a triphenylphosphonium and an antibiotic derivative MXF-P was prepared,which is able to specifically differentiate bacterial species after only 10 min of treatment.Moreover,MXF-P shows highly effective broad-spectrum antibacterial activity,excellent therapeutic effects and biosafety for S.aureus-infected wound recovery.Thus,this work not only discovers the multifunctionalities of the antibiotics but also provides a feasible strategy to make the commercialized drugs more powerful. | Bingnan Wang Lirong Wang Haozhong Wu Xiaolin Liu Jiamiao Zhu Rong Hu Dan Ding Anjun Qin Ben Zhong Tang | 2023 | Bioactive Materials2023，，5： | 0 |
| 15 | Manipulating the ion-transference and deposition kinetics by regulating the surface chemistry of zinc metal anodes for rechargeable zinc-air batteries显示文摘Aqueous zinc-air battery(ZAB)has attractive features as the potential energy storage system such as high safety,low cost and good environmental compatibility.However,the issue of dendrite growth on zinc metal anodes has seriously hindered the development of ZAB.Herein,the N-doped carbon cloth(NC)prepared via magnetron sputtering is explored as the substrate to induce the uniform nucleation of zinc metal and suppress dendrite growth.Results show that the introduction of heteroatoms accelerates the migration and deposition kinetics of Zn^(2+)by boosting the desolvation process of Zn^(2+),eventually reducing the nucleation overpotential.Besides,theoretical calculation results confirm the zincophilicity of N-containing functional group(such as pyridine N and pyrrole N),which can guide the nucleation and growth of zinc uniformly on the electrode surface by both promoting the redistribution of Zn^(2+) in the vicinity of the surface and enhancing its interaction with zinc atoms.As a result,the half-cell assembled with magnetron sputtered carbon cloth achieves a high zinc stripping/plating coulombic efficiency of 98.8%and long-term stability of over 500 cycles at 0.2 mA cm^(-2).And the Coulombic efficiency reached about 99.5%at the 10th cycle and maintained for more than 210 cycles at a high current density of 5.0 mA cm^(-2).The assembled symmetrical battery can deliver 220 plating/stripping cycles with ultra-low voltage hysteresis of only 11 mV.In addition,the assembled zinc-air full battery with NC-Zn anode delivers a high special capacity of about 429 mAh g_(Zn)^(-1) and a long life of over 430 cycles.The effectiveness of surface functionalization in promoting the transfer and deposition kinetics of Zn^(2+) presented in this work shows enlightening significance in the development of metal anodes in aqueous electrolytes. | Miao He Chaozhu Shu Ruixing Zheng Wei Xiang Anjun Hu Yu Yan Zhiqun Ran Minglu Li Xiaojuan Wen Ting Zeng Jianping Long | 2023 | Green Energy & Environment2023，8，1： | 0 |
| 16 | A Review of Reservoir Sedimentation Control and Storage Capacity Recovery显示文摘There are many reservoirs in China,and serious reservoir sedimentation affects reservoir function and reservoir safety.It is of great significance for restoring the reservoir capacity,improving the efficiency of the reservoir and prolonging the service life of the reservoir to carry out the research on reservoir sedimentation control and storage capacity recovery technology,in the case of fewer and fewer good dam sites suitable for the construction of the reservoir and the increasing accumulation of reservoir sedimentation.In this paper,influence factor of the storage loss,sedimentation control and reservoir capacity recovery technology in China are briefly reviewed.It is necessary to carry out research work on reservoir sedimentation investigation and reservoir siltation mechanism and control measures. | Anjun DENG Jianguo CHEN Haihua HU Hongling SHI | 2020 | Meteorological and Environmental Research2020，11，1： | 0 |
| 17 | Highly specific characterization and discrimination of monosodium urate crystals in gouty arthritis based on aggregation-induced emission luminogens显示文摘Existing technologies used to detect monosodium urate(MSU)crystals for gout diagnosis are not ideal due to their low sensitivity and complexity of operation.The purpose of this study was to explore whether aggregation-induced emission luminogens(AIEgens)can be used for highly specific imaging of MSU crystals to assist in the diagnosis of gout.First,we developed a series of luminogens(i.e.,tetraphenyl ethylene(TPE)-NH_(2),TPE-2NH_(2),TPE-4NH_(2),TPE-COOH,TPE-2COOH,TPE-4COOH,and TPE-Ketoalkyne),each of which was then evenly mixed with MSU crystals.Next,optimal fluorescence imaging of each of the luminogens was characterized by a confocal laser scanning microscope(CLSM).This approach was used for imaging standard samples of MSU,hydroxyapatite(HAP)crystals,and mixed samples with 1:1 mass ratio of MSU/HAP.We also imaged samples from mouse models of acute gouty arthritis,HAP deposition disease,and comorbidities of interest.Subsequently,CLSM imaging results were compared with those of compensated polarized light microscopy,and we assessed the biosafety of TPE-Ketoalkyne in the RAW264.7 cell line.Finally,CLSM time series and three-dimensional imaging were performed on MSU crystal samples from human gouty synovial fluid and tophi.As a promising candidate for MSU crystal labeling,TPE-Ketoalkyne was found to detect MSU crystals accurately and rapidly in standard samples,animal samples,and human samples,and could precisely distinguish gout from HAP deposition disease.This work demonstrates that TPE-Ketoalkyne is suitable for highly specific and timely imaging of MSU crystals in gouty arthritis and may facilitate future research on MSU crystal-related diseases. | Wenjuan Wang Guiquan Zhang Ziyi Chen Hanlin Xu Bohan Zhang Rong Hu Anjun Qin Yinghui Hua | 2023 | Bio-Design and Manufacturing2023，6，6： | 0 |
