| 1 | Challenges of organic pollutant photocatalysis by biochar‑based catalysts显示文摘With the fast development of industrialization and urbanization,large amounts of organic pollutants are released into the natural environment.The efficient elimination of organic pollutants is thereby crucial for environmental pollution treatment and human health.In the last decades,photocatalytic degradation of persistent organic pollutants has attracted multidisciplinary interest because of its simple operation on a large scale.However,the whole processes for the photocatalytic degradation of organic pollutants are still unclear.In this perspective,the contribution of reactive species,the contribution of photocatalysts,the analysis of intermediate products,the charge transfer and fast carrier recombination are discussed on biochar-based photocatalysts. | Muqing Qiu Baowei Hu Zhongshan Chen Hui Yang Li Zhuang Xiangke Wang | 2021 | Biochar2021，3，2： | 2 |
| 2 | Chemical functionalization of 2D black phosphorus显示文摘As an emerging two-dimensional material,black phosphorus(BP)has fascinating structure and electronic properties,affording broad applications in fieldeffect transistors,optoelectronic devices,energy devices,and biomedicines.However,the lone pair electrons of phosphorus atoms readily react with oxygen,so few-layer BP is easily oxidized and degraded when exposed to air.Therefore,the ambient stability of BP needs to be enhanced for its potential application.Chemical functionalization is one of the most effective methods for improving the ambient stability of few-layer BP.In this review,we provide a comprehensive overview of the chemical functionalization of BP,focusing on covalent and noncovalent functionalization and surface coordination.The influence of the functionalization pattern on the electronic properties and ambient stability of BP is summarized.Finally,the challenges and future development of chemical functionalization of BP are discussed. | Yajuan Liu Muqing Chen Shangfeng Yang | 2021 | InfoMat2021，3，3： | 2 |

| 4 | Regulating the radical intermediates by conjugated units in covalent organic frameworks for optimized lithium ion storage显示文摘Organic active units often transform into radical intermediates during the redox processes but exhibit poor cycling stability due to the uncontrollable redox of the radicals. Herein, we report a facile and efficient strategy to modulate the molecular orbital energies, charge transport capacities, and spin electron densities of the active units in covalent organic frameworks(COFs) via regulating the conjugated unit size to optimize the redox activity and stability of the organic radicals. COFs based on different imide conjugated units exhibit tunable discharge voltages, rate performance and cycling stabilities. Detailed characterizations and theoretical calculation reveal that imide radicals are the important active intermediates during the redox processes of these COFs. Specifically, increasing the size of the imide conjugated units could effectively delocalize the radical electrons and improve the stability of the COFs electrodes. This study offers a very effective strategy to modulate the redox chemistry of organic materials for electrochemical energy storage. | Shuai Gu Xiaoxia Ma Jingjing Chen Rui Hao Zhiqiang Wang Ning Qin Wei Zheng Qingmeng Gan Wen Luo Muqing Li Zhiqiang Li Kemeng Liao Hao Guo Guiyu Liu Kaili Zhang Zhouguang Lu | 2022 | Journal of Energy Chemistry2022，31，6： | 1 |
| 5 | Correlativity between blood measures related to blood stasis blocking collaterals and gene expression of angiotensin-converting enzyme of renal cortex in diabetic rats and effect of stasis removing and collaterals dredging显示文摘OBJECTIVE: To investigate the correlativity between the changes of blood measures related to blood stasis blocking collaterals and gene expression levels of angiotensin-converting enzyme(ACE)and ACE2 ofrenal cortex in diabetic rats with stasis blocking collaterals syndrome, as well as the effectof stasis removing and collaterals dredging.METHODS: Male Sprague-Dawley rats were divided randomly into normal control group(C group),high-carbohydrate-fat control group(H group) and streptozotocin(STZ)-injecting group. The diabeticrats were induced from rats in the STZ-injecting groupby high-carbohydrate-fat diet combined with STZ intraperitoneal injection, with sustained high-carbohydrate-fat diet fed afterwards, and were further divided into model group(M group)and Chinese medicine of stasis removing and collaterals dredging group(Z group). Rats in the Z group were fed with stasis-removing-and-collaterals-dredging herbal granule suspension intragastrically daily for 16 weeks, while drinking water of corresponding volume was administrated to the rats in other groups. At the end of the 16 th week after successful establishment of models, the ultrastructures of glomeruli in different groups were detected by a transmission electron microscopy; and blood measures related to blood stasis blocking collaterals, including lipid profile and blood viscosity measures, were tested, as well as the relative gene expressions of ACE and ACE2.RESULTS: Changes in ultrastructures of glomeruli in the M group were characterized by lack of clarity in structure and occasional thickening of glomerular basement membrane and extensive fusion in foot processes. The correlation analysis showed that there were positive correlations between lipid profile, blood viscosity, and the ACE mRNA expression levels in the M group(P<0.05), except for cholesterol. And except for triglyceride, the blood measures were in negative correlation with the ACE2 mRNA expression levels in the M group(P<0.05).Compared with the C and H groups, the lipid profile, plasma viscosity and blood viscosity were significantly higher(P<0.01). All the above-mentioned measures were significantly improved in the Z group rats(P<0.05). ACE mRNA expression was significantly higher in the M group thanin the C group(P<0.05). ACE2 mRNA level was significantly lower in the M group than in the C and H groups(P<0.01)and its levelin the Z group was higher than that in the M group(P<0.01).CONCLUSION: Blood measuresrelated to blood stasis blocking collaterals had positive linear correlations with ACE mRNAexpression and negative linear correlations with ACE2 mRNA expression in the M group. Chinese recipe of stasis removing and collaterals dredging could play a renal protecting role for diabetic rats by reducing lipid profile and blood viscosity, down-regulating ACE mRNA expression and up-regulating ACE2 mRNA expression. | Jing Xu Lu Bai Erwei Ma Qian Guo Yuehua Wang Muqing Zhang Zhiqiang Chen | 2014 | Journal of Traditional Chinese Medicine2014，34，5： | 1 |

| 7 | A gap-free and haplotype-resolved lemon genome provides insights into flavor synthesis and huanglongbing (HLB) tolerance显示文摘The lemon(Citrus limon;family Rutaceae)is one of the most important and popular fruits worldwide.Lemon also tolerates huan-glongbing(HLB)disease,which is a devastating citrus disease.Here we produced a gap-free and haplotype-resolved chromosome-scale genome assembly of the lemon by combining Pacific Biosciences circular consensus sequencing,Oxford Nanopore 50-kb ultra-long,and high-throughput chromatin conformation capture technologies.The assembly contained nine-pair chromosomes with a contig N50 of 35.6 Mb and zero gaps,while a total of 633.0 Mb genomic sequences were generated.The origination analysis identified 338.5Mb genomic sequences originating from citron(53.5%),147.4Mb frommandarin(23.3%),and 147.1Mb frompummelo(23.2%).The genome included 30528 protein-coding genes,and most of the assembled sequences were found to be repetitive sequences.Several significantly expanded gene families were associated with plant-pathogen interactions,plant hormone signal transduction,and the biosynthesis of major active components,such as terpenoids and f lavor compounds.Most HLB-tolerant genes were expanded in the lemon genome,such as 2-oxoglutarate(2OG)/Fe(II)-dependent oxygenase and constitutive disease resistance 1,cell wall-related genes,and lignin synthesis genes.Comparative transcriptomic analysis showed that phloem regeneration and lower levels of phloem plugging are the elements that contribute to HLB tolerance in lemon.Our results provide insight into lemon genome evolution,active component biosynthesis,and genes associated with HLB tolerance. | Yixue Bao Ziyan Zeng Wei Yao Xiao Chen Mengwei Jiang Akbar Sehrish Bo Wu Charles A.Powell Baoshan Chen Jianlong Xu Xingtan Zhang Muqing Zhang | 2023 | Horticulture Research2023，10，4： | 0 |
| 8 | An active high-static-low-dynamic-stiffness vibration isolator with adjustable buckling beams:theory and experiment显示文摘High-static-low-dynamic-stiffness(HSLDS)vibration isolators with buckling beams have been widely used to isolate external vibrations.An active adjustable device composed of proportion integration(PI)active controllers and piezoelectric actuators is proposed for improving the negative stiffness stroke of buckling beams.A nonlinear output frequency response function is used to analyze the effect of the vibration reduction.The prototype of the active HSLDS device is built,and the verification experiment is conducted.The results show that compared with the traditional HSLDS vibration isolator,the active HSLDS device can broaden the isolation frequency bandwidth,and effectively reduce the resonant amplitude by adjusting the active control parameters.The maximum vibration reduction rate of the active HSLDS vibration isolator can attain 89.9%,and the resonant frequency can be reduced from 31.08 Hz to 13.28 Hz.Therefore,this paper devotes to providing a new design scheme for enhanced HSLDS vibration isolators. | Kefan XU Muqing NIU Yewei ZHANG Liqun CHEN | 2024 | Applied Mathematics and Mechanics(English Edition)2024，45，3： | 0 |
| 9 | Recent Advances in Functionalized Fullerenes in Perovskite Solar Cells显示文摘Comprehensive Summary,Efficient charge transport and defect passivation are essential for high efficiency of organic–inorganic hybrid perovskite solar cells(PSCs).Functionalized fullerenes featuring high electron affinity and mobility as well as small reorganization energy have been extensively applied in PSCs toward facilitated electron transport and passivated trap states,leading to improvements of both device efficiency and stability.Herein,we summarize the recent advances,especially in the last three years,in applications of functionalized fullerenes including fullerene derivatives and endohedral metallofullerenes in PSCs.Their functions in trap state passivation,electron transport promotion,crystalline modulation,water/oxygen erosion inhibition,and so on,are discussed in details.In particular,we emphasize novel functions of fullerenes beyond trap state passivation,as well as the synergy of multifunction of fullerenes in improving PSC device performance and stability.Finally,we present an outlook on designing novel multifunctionalized fullerenes toward highly efficient and stable PSC devices. | Min Ai Muqing Chen Shangfeng Yang | 2023 | Chinese Journal of Chemistry2023，41，18： | 0 |
| 10 | Synergistic fluorescent hydrogel actuators with selective spatial shape/color-changing behaviors via interfacial supramolecular assembly显示文摘Biomimetic intelligent polymeric hydrogel actuators with cooperative fluorescence-color switchable behaviors are expected to find great potential applications in soft robotics,visual detection/display,and camouflage applications.However,it remains challenging to realize the spatial manipulation of synergistic shape/color-changing behaviors.Herein,we report an interfacial supramolecular assembly(ISA)approach that enables the construction of robust fluorescent polymeric hydrogel actuators with spatially anisotropic structures.On the basis of this ISA approach,diverse 2D/3D soft fluorescent hydrogel actuators,including chameleon-and octopi-shaped ones with spatially anisotropic structures,were facilely assembled from two different fluorescent hydrogel building blocks sharing the same physically cross-linked agar network.Spatially control over synergistic shape/color-changing behaviors was then realized in one single anisotropic hydrogel actuator.The proposed ISA approach is universal and expected to open promising avenues for developing powerful bioinspired intelligent soft actuators/robotics with selective spatial shape/color-changing behaviors. | Wei Lu Ruijia Wang Muqing Si Yi Zhang Shuangshuang Wu Ning Zhu Wenqin Wang Tao Chen | 2024 | SmartMat2024，5，2： | 0 |
| 11 | Pomegranate-like C_(60)@cobalt/nitrogen-codoped porous carbon for high-performance oxygen reduction reaction and lithium-sulfur battery显示文摘Porous carbon materials play essential roles in electrocatalysis and electrochemical energy storage.It is of significant importance to rationally design and tune their porous structure and active sites for achieving high electrochemical activity and stability.Herein,we develop a novel approach to tune the morphology of porous carbon materials(PCM)by embedding fullerene C_(60),achieving improved performance of oxygen reduction reaction(ORR)and lithium-sulfur(Li-S)battery.Owing to the strong interaction between C_(60)and imidazole moieties,pomegranate-like hybrid of Ow-embedded zeolitic imidazolate framework(ZIF-67)precursor is synthesized,which is further pyrolyzed to form C_(60)-embedded cobalt/nitrogen-codoped porous carbon materials(abbreviated as C_(60)@Co-N-PCM).Remarkably,the unique structure of C_(60)@Co-N-PCM offers excellent ORR electrocatalytic activity and stability in alkaline solutions,outperforming the commercial Pt/C(20 wt.%)catalyst.Besides,C_(60)@Co-N-PCM as a novel cathode delivers a high specific capacity of-900 mAh·g^(-1) at 0.2 C rate in Li-S batteries,which is superior to the pristine ZIF-67-derived PCM without embedding C_(60). | Jianhua Wu Shiyang Wang Zhanwu Lei Runnan Guan Muqing Chen Pingwu Du Yalin Lu Ruiguo Cao Shangfeng Yang | 2021 | Nano Research2021，14，8： | 0 |
| 12 | Development of a novel virus-like particle-based vaccine for preventing tick-borne encephalitis virus infection显示文摘Tick-borne encephalitis virus(TBEV)is an important tick-borne pathogen that poses as a serious public health concern.The coverage and immunogenicity of the currently available vaccines against TBEV are relatively low;therefore,it is crucial to develop novel and effective vaccines against TBEV.The present study describes a novel strategy for the assembly of virus-like particles(VLPs)by co-expressing the structural(core/prM/E)and non-structural(NS2B/NS3Pro)proteins of TBEV.The efficacy of the VLPs was subsequently evaluated in C57BL/6 mice,and the resultant IgG serum could neutralize both Far-Eastern and European subtypes of TBEV.These findings indicated that the VLP-based vaccine elicited the production of cross-subtype reactive antibodies.The VLPs provided protection to mice lacking the type I interferon receptor(IFNAR^(-/-))against lethal TBEV challenge,with undetectable viral load in brain and intestinal tissues.Furthermore,the group that received the VLP vaccine did not exhibit significant pathological changes and the inflammatory factors were significantly suppressed compared to the control group.Immunization with the VLP vaccine induced the production of multiple-cytokine-producing antiviral CD4+T cells in vivo,including TNF-α^(+),IL-2^(+),and IFN-γ^(+)T cells.Altogether,the findings suggest that noninfectious VLPs can serve as a potentially safe and effective vaccine candidate against diverse subtypes of TBEV. | Jielin Tang Muqing Fu Chonghui Xu Bao Xue Anqi Zhou Sijie Chen He Zhao Yuan Zhou Jizheng Chen Qi Yang Xinwen Chen | 2023 | Virologica Sinica2023，38，5： | 0 |
| 13 | Synchronous defect passivation of all-inorganic perovskite solar cells enabled by fullerene interlayer显示文摘All-inorganic CsPbI_(3-x)Br_(x)perovskite solar cells(PSCs)are advantageous in terms of high thermal stability,while its efficiency lags behind those of organic-inorganic hybrid perovskite counterparts.Defect passivations have been extensively applied for enhancing efficiency of all-inorganic PSCs,which are mainly based on univocal defect passivation of perovskite layer.Herein,we incorporated a bis-dimethylamino-functionalized fullerene derivative(abbreviated as PCBDMAM)as an interlayer between ZnO electron transport layer(ETL)and all-inorganic CsPbI_(2.25)Br_(0.75)perovskite layer,accomplishing synchronous defect passivations of both layers and consequently dramatic enhancements of efficiency and thermal stability of PSC devices.Upon spin-coating PCBDMAM onto ZnO ETL,the surface defects of ZnO especially oxygen vacancies can be effectively passivated due to the formation of Zn−N ionic bonds.In addition,PCBDMAM incorporation affords effective passivation of Pb_(I)and I_(Pb)antisite defects within the atop perovskite layer as well via coordination bonding with Pb^(2+).As a result,the regular-structure planar CsPbI_(2.25)Br_(0.75)PSC device delivers a champion power conversion efficiency(PCE)of 17.04%,which surpasses that of the control device(15.44%).Moreover,the PCBDMAM-incorporated PSC device maintains~80%of its initial PCE after 600 h heating at 85°C hot plate in N2 atmosphere,whereas PCE of the control device degrades rapidly to~62%after 460 h heating under identical conditions.Hence,PCBDMAM incorporation benefited dramatic improvement of the thermal stability of PSC device. | Yanbo Shang Pu Wang Lingbo Jia Xingcheng Li Weitao Lian Peisen Qian Muqing Chen Tao Chen Yalin Lu Shangfeng Yang | 2023 | Nano Research Energy2023，2，3： | 0 |
| 14 | Mechanochemical transformation of fluorescent hydrogel based on dynamic lanthanide-terpyridine coordination显示文摘As a burgeoning research field, ultrasound-responsive materials have attracted intense interest in healthcare research. However, the basic mechanism of sonochemical effect in the quasi-solid state is far from being well understood than those in the solution. Herein, we showcase mechanochemical transformations of europium(Ⅲ) complexes in a supramolecular hydrogel matrix. With the combination of labile terpyridine-europium complexes(TPY-Eu^(3+)) as mechanochromic moieties and an ultrasound-responsive fluorogen(URF) as a molecular tweezer, the hydrogel produces a notable fluorescence change in response to ultrasound. The mechanochemical transformation was elucidated by molecular dynamics(MD) simulations, and fully probed and evidenced by electrochemical experiments, X-ray photoelectron spectroscopy(XPS), and attenuated total reflectance-Fourier transform infrared(ATR-FTIR) spectroscopy. | Guangqiang Yin Jianxiang Huang Depeng Liu Rui Li Shuxin Wei Muqing Si Feng Ni Yinfei Zheng Qiu Yang Ruhong Zhou Xiaoxia Le Wei Lu Tao Chen | 2023 | Chinese Chemical Letters2023，34，3： | 0 |
