| 1 | NEW METHOD OF EXTRACTING WEAK FAILURE INFORMATION IN GEARBOX BY COMPLEX WAVELET DENOISING显示文摘Because the extract of the weak failure information is always the difficulty and focus of fault detection.Aiming for specific statistical properties of complex wavelet coefficients of gearbox vibration signals,a new signal-denoising method which uses local adaptive algorithm based on dual-tree complex wavelet transform(DT-CWT)is introduced to extract weak failure information in gear,especially to extract impulse components.By taking into account the non-Gaussian probability distribution and the statistical dependencies among wavelet coefficients of some signals, and by taking the advantage of near shift-invariance of DT-CWT,the higher signal-to-noise ratio(SNR)than common wavelet denoising methods can be obtained. Experiments of extracting periodic impulses in gearbox vibration signals indicate that the method can extract incipient fault feature and hidden information from heavy noise,and it has an excellent effect on identifying weak feature signals in gearbox vibration signals. | CHEN Zhixin XU Jinwu YANG Debin | 2008 | Chinese Journal of Mechanical Engineering2008，21，4： | 18 |
| 2 | Reverse reconciliation for continuous variable quantum key distribution显示文摘An efficient and practical post-processing technique based on reverse reconciliation for continuous variable quantum key distribution is proposed and simulated with low-density parity check (LDPC) codes. MultiLevel Coding/ MultiStage Decoding, which fully utilizes optimization technique such as vector quantization and iterative decoding and the optimal channel coding most close to the Shannon limit, was used to realize efficient reverse reconciliation algorithm. Simulation results showed that the proposed method can improve the secure key distribution rate to 2.2 kb/s and the coding efficiency to 0.89 over 20 km in single-mode optical fiber. Moreover, there still is room for much improvement. | LU ZhiXin 1,2 , YU Li 1,2 , LI Kang 1,2 , LIU BingCan 1,2,3 , LIN JianGui 1,2 , JIAO RongZhen 1,2 & YANG BoJun 1,21 School of Science, Beijing University of Posts and Telecommunications, Beijing 100876, China 2 Key Laboratory of Information Photonics and Optical Communication, Ministry of Education, Beijing University of Posts and Telecommunications, Beijing 100876, China 3 Department of Fundamental Courses, Academy of Armored Force Engineering, Beijing 100072, China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，1： | 12 |
| 3 | Power Matching and Energy Efficiency Improvement of Hydraulic Excavator Driven with Speed and Displacement Variable Power Source显示文摘Mobile machinery energy efficiency and emission pollution are the national and worldwide issues. This paper contributes in solving these problems by applying a speed variable power source. Unfortunately, almost all of the speed variable systems have the dynamic response problem when the motor starts with full load or heavy load. To address this problem, a hydraulic accumulator is used to balance the load of the power source for assisting starting of the motor and a matching method combined with speed and displacement control of the pump is proposed to improve the energy efficiency and dynamic performance simultaneously under different working conditions. Also, the power source/valve combined control strategy of an independent metering system is designed to realize flow matching of the whole system. Firstly, a test system is established to study the dynamic performance and energy efficiency of the speed variable power source with an auxiliary accumulator. Working performance and energy consumption of the power source under different rotating speeds and different loads are studied. And then, the hydraulic excavator test rig with the proposed system is constructed. Furthermore, the working performance of the excavator with the speed-fixed and speed-variable strategy are studied comparatively. Results show that, compared with fixed-speed strategy, the electric power consumption during the idle period and partial load condition can be reduced about 2.05 kW and 1.37 kW. The energy efficiency of speed variable power source is about 40%-71%, which is higher than that of the fixed-speed power source by 3%–10%. | Lei Ge Long Quan Xiaogang Zhang Zhixin Dong Jing Yang | 2019 | Chinese Journal of Mechanical Engineering2019，32，6： | 10 |
| 4 | Dynamic blood single-cell immune responses in patients with COVID-19显示文摘The 2019 coronavirus disease(COVID-19)outbreak caused by the SARS-CoV-2 virus is an ongoing global health emergency.However,the virus'pathogenesis remains unclear,and there is no cure for the disease.We investigated the dynamic changes of blood immune response in patients with COVID-19 at different stages by using 5'gene expression,T cell receptor(TCR),and B cell receptors(BCR)V(D)J transcriptome analysis at a single-cell resolution.We obtained single-cell mRNA sequencing(scRNA-seq)data of 341,420 peripheral blood mononuclear cells(PBMCs)and 185,430 donotypic T cells and 28,802 donotypic B cells from 25 samples of 16 patients with COVID-19 for dynamic studies.In addition,we used three control samples.We found expansion of dendritic cells(DCs),CD14+monocytes,and megakaryocytes progenitor cells(MP)/platelets and a reduction of naive CD4+T lymphocytes in patients with COVID-19,along with a significant decrease of CD8+T lymphocytes,and natural killer cells(NKs)in patients in critical condition.The type I interferon(IFN-I),mitogen-activated protein kinase(MAPK),and ferroptosis pathways were activated while the disease was active,and recovered gradually after patient conditions improved.Consistent with this finding,the mRNA level of IFN-I signal-induced gene IFI27 was significantly increased in patients with COVID-19 compared with that of the controls in a validation cohort that included 38 patients and 35 controls.The concentration of interferon-a(IFN-a)in the serum of patients with COVID-19 increased significantly compared with that of the controls in an additional cohort of 215 patients with COVID-19 and 106 controls,further suggesting the important role of the IFN-I pathway in the immune response of COVID-19.TCR and BCR sequences analyses indicated that patients with COVID-19 developed specific immune responses against SARS-CoV-2 antigens.Our study reveals a dynamic landscape of human blood immune responses to SARS-CoV-2 infection,providing clues for therapeutic potentials in treating COVID-19. | Lulin Huang Yi Shi Bo Gong Li Jiang Zhixin Zhang Xiaoqi Liu Jialiang Yang Yongquan He Zhilin Jiang Ling Zhong Juan Tang Chunfang You Qi Jiang Bo Long Tao Zeng Mei Luo Fanwei Zeng Fanxin Zeng Shuqiang Wang Xingxiang Yang Zhenglin Yang | 2021 | Signal Transduction and Targeted Therapy2021，6，4： | 4 |
| 5 | GaN-based substrates and optoelectronic materials and devices显示文摘In order to solve the problems of GaN heteroepitaxy on sapphire substrate,some techniques were explored.Freestanding GaN substrates have been made by hydride vapor phase epitaxy(HVPE),laser lift-off(LLO),and chemical mechanical polishing techniques.Wafer bending and cracking in the HVPE growth were partly settled by pulsed flow modulation method.High-crystal quality was established for 1.2 mm thick GaN substrate by X-ray diffraction measurement,in which the full width of half maximum values were 72,110 arcsec for(102),(002)peaks.A novel micro-size patterned sapphire substrate(PSS)and a nano PSS were also fabricated.High-power vertical structure light emitting diodes(VSLEDs)have been developed by Au–Sn eutectic wafer bonding,homemade micro-area LLO,and light extraction structure preparation.The high-injection-level active region with low temperature GaN sandwiched layers was used for lowefficiency droop.The light output power of VSLED was achieved as 400 mW driven at 350 mA,and the dominant wavelength is about 460 nm.The structures and properties of strain modulated superlattices(SLs)and quantum wells as well as advanced simulation of carriers transport across the electron blocking layer were investigated in laser diodes.The hole concentration was achieved as high as1.6 9 1018cm-3in AlGaN/GaN SLs:Mg by inserting an AlN layer.High-quality AlGaN epilayers and structures were grown by MOCVD.Some device structures of UV LEDs and detectors were demonstrated.The emission wavelength of 262 nm UV LED has been successfully fabricated.At last,high-quality InN and InGaN materials for solar cell were grown by boundary-temperature-controlled epitaxy and growth-temperature-controlled epitaxy.Hall-effect measurement showed a recorded electron mobility of 3,280 cm2/(V s)and a residual electron concentration of 1.47 9 1017cm-3at 300 K. | Guoyi Zhang Bo Shen Zhizhong Chen Xiaodong Hu Zhixin Qin Xinqiang Wang Jiejun Wu Tongjun Yu Xiangning Kang Xingxing Fu Wei Yang Zhijian Yang Zhizhao Gan | 2014 | Chinese Science Bulletin2014，59，12： | 4 |
| 6 | COVID-19:immunopathogenesis and Immunotherapeutics显示文摘The recent novel coronavirus disease(COVID-19)outbreak,caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),is seeing a rapid increase in infected patients worldwide.The host immune response to SARS-CoV-2 appears to play a critical role in disease pathogenesis and clinical manifestations.SARS-CoV-2 not only activates antiviral immune responses,but can also cause uncontrolled inflammatory responses characterized by marked pro-inflammatory cytokine release in patients with severe COVID-19,leading to lymphopenia,lymphocyte dysfunction,and granulocyte and monocyte abnormalities.These SARS-CoV-2-induced immune abnormalities may lead to infections by microorganisms,septic shock,and severe multiple organ dysfunction.Therefore,mechanisms underlying immune abnormalities in patients with COVID-19 must be elucidated to guide clinical management of the disease.Moreover,rational management of the immune responses to SARSCoV-2,which includes enhancing anti-viral immunity while inhibiting systemic inflammation,may be key to successful treatment.In this review,we discuss the immunopathology of COVID-19,its potential mechanisms,and clinical implications to aid the development of new therapeutic strategies against COVID-19. | Li Yang Shasha Liu Jinyan Liu Zhixin Zhang Xiaochun Wan Bo Huang Youhai Chen Yi Zhang | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 4 |
| 7 | Phonon scattering and exciton localization: molding exciton flux in two dimensional disorder energy landscape显示文摘Two dimensional excitonic devices are of great potential to overcome the dilemma of response time and integration in current generation of electron or/and photon based systems.The ultrashort diffusion length of exciton arising from ultrafast relaxation and low carrier mobility greatly discounts the performance of excitonic devices.Phonon scattering and exciton localization are crucial to understand the modulation of exciton flux in two dimensional disorder energy landscape,which still remain elusive.Here,we report an optimized scheme for exciton diffusion and relaxation dominated by phonon scattering and disorder potentials in WSe2 monolayers.The effective diffusion coefficient is enhanced by>200%at 280 K.The excitons tend to be localized by disorder potentials accompanied by the steadily weakening of phonon scattering when temperature drops to 260 K,and the onset of exciton localization brings forward as decreasing temperature.These findings identify that phonon scattering and disorder potentials are of great importance for long-range exciton diffusion and thermal management in exciton based systems,and lay a firm foundation for the development of functional excitonic devices. | Pengfei Qi Yang Luo Beibei Shi Wei Li Donglin Liu Liheng Zheng Zhixin Liu Yanglong Hou Zheyu Fang | 2021 | eLight2021，1，1： | 3 |
| 8 | Hydroiodic Acid Additive Enhanced the Performance and Stability of PbS-QDs Solar Cells via Suppressing Hydroxyl Ligand显示文摘The recent emerging progress of quantum dot ink(QD-ink)has overcome the complexity of multiple-step colloidal QD(CQD)film preparation and pronouncedly promoted the device performance.However,the detrimental hydroxyl(OH)ligands induced from synthesis procedure have not been completely removed.Here,a halide ligand additive strategy was devised to optimize QD-ink process.It simultaneously reduced sub-bandgap states and converted them into iodide-passivated surface,which increase carrier mobility of the QDs films and achieve thicker absorber with improved performances.The corresponding power conversion efficiency of this optimized device reached 10.78%.(The control device was 9.56%.)Therefore,this stratege can support as a candidate strategy to solve the QD original limitation caused by hydroxyl ligands,which is also compatible with other CQD-based optoelectronic devices. | Xiaokun Yang Ji Yang Jahangeer Khan Hui Deng Shengjie Yuan Jian Zhang Yong Xia Feng Deng Xue Zhou Farooq Umar Zhixin Jin Haisheng Song Chun Cheng Mohamed Sabry Jiang Tang | 2020 | Nano-Micro Letters2020，12，3： | 2 |
| 9 | Cartilage oligomeric matrix protein is an endogenous β-arrestin-2-selective allosteric modulator of AT1 receptor counteracting vascular injury显示文摘Compelling evidence has revealed that biased activation of G protein-coupled receptor(GPCR)signaling,including angiotensin II(AngII)receptor type 1(AT1)signaling,plays pivotal roles in vascular homeostasis and injury,but whether a clinically relevant endogenous biased antagonism of AT1 signaling exists under physiological and pathophysiological conditions has not been clearly elucidated.Here,we show that an extracellular matrix protein,cartilage oligomeric matrix protein(COMP),acts as an endogenous allosteric biased modulator of the AT1 receptor and its deficiency is clinically associated with abdominal aortic aneurysm(AAA)development.COMP directly interacts with the extracellular N-terminus of the AT1 via its EGF domain and inhibits AT1-β-arrestin-2 signaling,but not Gq or Gi signaling,in a selective manner through allosteric regulation of AT1 intracellular conformational states.COMP deficiency results in activation of AT1a-β-arrestin-2 signaling and subsequent exclusive AAA formation in response to AngII infusion.AAAs in COMP–/–or ApoE–/–mice are rescued by AT1a orβ-arrestin-2 deficiency,or the application of a peptidomimetic mimicking the AT1-binding motif of COMP.Explorations of the endogenous biased antagonism of AT1 receptor or other GPCRs may reveal novel therapeutic strategies for cardiovascular diseases. | Yi Fu Yaqian Huang Zhao Yang Yufei Chen Jingang Zheng Chenfeng Mao Zhiqing Li Zhixin Liu Bing Yu Tuoyi Li Meili Wang Chanjuan Xu Yiwei Zhou Guizhen Zhao Yiting Jia Wei Guo Xin Jia Tao Zhang Li Li Ziyi Liu Shengchao Guo Mingliang Ma Heng Zhang Bo Liu Junbao Du Wengong Wang Chaoshu Tang Pei Gao Qingbo Xu Xian Wang Jianfeng Liu Jinpeng Sun Wei Kong | 2021 | Cell Research2021，31，7： | 2 |
| 10 | Effect of Fanbaicao(Herba Potentillae Discoloris) oil on the expression of p21 and CDK4 in HepG2 cells显示文摘OBJECTIVE:To research the anti-cancer mechanism of the Traditional Chinese Medicine Fanbaicao(Herba Potentillae Discoloris) oil in the human hepatoma cell line Hep G2.METHODS:Gas chromatography was used to analyze the components of Fanbaicao(Herba Potentillae Discoloris).We tested the inhibitory effect of Fanbaicao(Herba Potentillae Discoloris) oil on the human hepatoma cell line Hep G2 in vitro using 3-(4,5-Dimet hylt hiazol-2-yl)-2,5-dip henyltetrazoliumbromide assays.Fluorescence activating cell sorter analysis was used to examine the levels of apoptosis,and western blot and immunofluorescence were used to detect the expression of p21,p-p21 and CDK4 proteins.RESULTS:Fanbaicao(Herba Potentillae Discoloris)oil contains 45 ingredients,and L-ascorbic acid 2,6-bispalmitate was the main component and accounted for 44.96% of total drive-off peak area.Other components included(Z)-14-met hyl-8-exadecenal-acetal(8.56%),phytol(7.74%) and lauric acid(6.31%).Fanbaicao(Herba Potentillae Discoloris)oil treatment reduced the proliferation of Hep G2 cells and the half growth inhibition concentration(IC50) was 2.03 mg/m L.Furthermore,we also observed significantly increased Hep G2 cell apoptosis in a dose-dependent manner(P < 0.05).Fanbaicao(Herba Potentillae Discoloris) oil significantly increased the expression of p21 and p-p21 and significantly decreased the expression of CDK4 in Hep G2 cells compared with controls(P < 0.01).CONCLUSION:Our results showed that Fanbaicao(Herba Potentillae Discoloris) oil has anti-cancer activities in Hep G2 cells,which is probably related to the upregulation of p21 and p-p21 and downregulation of CDK4 expression. | Liu Lei Chen Guang Wang Baixin Chen Liping Wang Shuqiu Liu Zhixin Ma Xiaoru Wang Fangfang Liang Yanfeng Wu Jiamei Yang Zhiwei | 2016 | Journal of Traditional Chinese Medicine2016，36，4： | 1 |
| 11 | The C_(6)D_(6)detector system on the Back-n beam line of CSNS显示文摘Introduction The neutron capture cross sections are very important in the field of nuclear device design and basic physics research.Hydrogen-free liquid scintillator such as C_(6)D_(6)detectors are widely used in the neutron capture cross-sectional measurements for the low neutron sensitivity and fast time response.The Back-n white neutron source at China Spallation Neutron Source is the first spallation white neutron source in China,and it is suitable for neutron capture cross-sectional measurement.Materials and methods A C_(6)D_(6)detector system was built in the Back-n experimental station.The pulse height weighting technique was used to determine the system’s detection efficiency.The response to gamma rays of the C_(6)D_(6)detector was measured,and the energy resolution function was determined.Monte Carlo simulation with Geant4 code was carried out to get the weighting function of this C_(6)D_(6)detector system.Additionally,the systematic uncertainty of the weighting function was also determined.Conclusion According to the experimental and simulation results,this C_(6)D_(6)detector system can be used to measure neutron capture cross section. | Jie Ren Xichao Ruan Jie Bao Guangyuan Luan Wei Jiang Qi An Huaiyong Bai Ping Cao Qiping Chen Yonghao Chen Pinjing Cheng Zengqi Cui Ruirui Fan Changqing Feng Minhao Gu Fengqin Guo Changcai Han Zijie Han Guozhu He Yongcheng He Yuefeng He Hanxiong Huang Weiling Huang Xiru Huang Xiaolu Ji Xuyang Ji Haoyu Jiang Hantao Jing Ling Kang Mingtao Kang Bo Li Lun Li Qiang Li Xiao Li Yang Li Yang Li Rong Liu Shubin Liu Xingyan Liu Yinglin Ma Changjun Ning Binbin Qi Zhaohui Song Hong Sun Xiaoyang Sun Zhijia Sun Zhixin Tan Hongqing Tang Jingyu Tang Pengcheng Wang Qi Wang Taofeng Wang Yanfeng Wang Zhaohui Wang Zheng Wang Jie Wen Zhongwei Wen Qingbiao Wu Xiaoguang Wu Xuan Wu Likun Xie Yiwei Yang Han Yi Li Yu Tao Yu Yongji Yu Guohui Zhang Jing Zhang Linhao Zhang Liying Zhang Qingmin Zhang Qiwei Zhang Xianpeng Zhang Yuliang Zhang Zhiyong Zhang Yingtan Zhao Liang Zhou Zuying Zhou Danyang Zhu Kejun Zhu Peng Zhu | 2019 | Radiation Detection Technology and Methods2019，3，3： | 1 |

| 13 | N-Glycoproteomics Study of Putative N-Glycoprotein Biomarkers of Drug Resistance in MCF-7/ADR Cells显示文摘Currently,drug resistance of anti-cancer therapy has become the main cause of low survival rate and poor prognosis.Full understanding of drug resistance mechanisms is an urgent request for further development of anti-cancer therapy and improve-ment of prognosis.Here we present our N-glycoproteomics study of putative N-glycoprotein biomarkers of drug resistance in doxorubicin resistance breast cancer cell line michigan cancer foundation-7(MCF-7/ADR)relative to parental michigan cancer foundation-7(MCF-7)cells.Intact N-glycopeptides(IDs)from MCF-7/ADR and MCF-7 cells were enriched with zwitterionic hydrophilic interaction liquid chromatography(ZIC-HILIC),labeled with stable isotopic diethylation(SIDE),and analyzed with C18-RPLC-MS/MS(HCD with stepped normalized collision energies);these IDs were identified with database search engine GPSeeker,and the differentially expressed intact N-glycopeptides(DEGPs)were quantified with GPSeekerQuan.With target-decoy searches and control of spectrum-level FDR≤1%,322 intact N-glycopeptides were identified;these intact N-glycopeptides come from the combination of 249 unique peptide backbones(corresponding to 234 intact N-glycoproteins)and 90 monosaccharide compositions(corresponding to 248 putative N-glycosites).The sequence structures of 165 IDs were confirmed with structure-diagnostic fragment ions.With the criteria of observation at least twice among the three technical replicates,≥1.5-fold change and p value<0.05,20 DEGPs were quantified,where five of them were up-regulated and 15 of them were down-regulated;the corresponding intact N-glycoproteins as putative markers of drug resistance were discussed. | Hailun Yang Feifei Xu Kaijie Xiao Yun Chen Zhixin Tian | 2021 | Phenomics2021，1，6： | 1 |
| 14 | Game-theoretical explorations of the mesoscale flow structure and regime transitions in bubble columns显示文摘Understanding the mesoscale structure and regime transition in bubble columns is of great significance for reactor design and scaleup.Based on the energy-minimization multiscale(EMMS)model,a noncooperative game model with constraints is proposed to investigate the structural properties of gas-liquid systems in which small and large bubbles are chosen as players and the energy consumption form the objective function.The conservation equations of the system can be regarded as the constraints of the game.For the formulated noncooperative game model,the concept of the generalized Nash equilibrium(GNE)is used to characterize the solution.An algorithm is developed to numerically compute the GNE and some important structural parameters in the system.The numerical results show the existence of the GNE for all values of the superficial gas velocity Ug.As Ug varies,the trends in the state variables can be observed and the critical point of Ug identified.The overall trend of the flow regime transition agrees with the original EMMS model and experimental results,although the GNE calculation also reveals different single-bubble dominant mechanisms with increasing Ug. | Shuo Yuan Yifen Mu Xiaoping Guan Zhixin Liu Jianhua Chen Ning Yang Lin Zhang | 2020 | Particuology2020，18，1： | 1 |

| 16 | LncRNA DACH1 protects against pulmonary fibrosis by binding to SRSF1 to suppress CTNNB1 accumulation显示文摘Idiopathic pulmonary fibrosis(IPF)is a progressive disease with unknown etiology and limited therapeutic options.Activation of fibroblasts is a prominent feature of pulmonary fibrosis.Here we report that lncRNA DACH1(dachshund homolog 1)is downregulated in the lungs of IPF patients and in an experimental mouse model of lung fibrosis.LncDACH1 knockout mice develop spontaneous pulmonary fibrosis,whereas overexpression of LncDACH1 attenuated TGF-β1-induced aberrant activation,collagen deposition and differentiation of mouse lung fibroblasts.Similarly,forced expression of LncDACH1 not only prevented bleomycin(BLM)-induced lung fibrosis,but also reversed established lung fibrosis in a BLM model.Mechanistically,LncDACH1 binding to the serine/arginine-rich splicing factor 1(SRSF1)protein decreases its activity and inhibits the accumulation of Ctnnb1.Enhanced expression of SRSF1 blocked the anti-fibrotic effect of LncDACH1 in lung fibroblasts.Furthermore,loss of LncDACH1 promoted proliferation,differentiation,and extracellular matrix(ECM)deposition in mouse lung fibroblasts,whereas such effects were abolished by silencing of Ctnnb1.In addition,a conserved fragment of LncDACH1 alleviated hyperproliferation,ECM deposition and differentiation of MRC-5 cells driven by TGF-β1.Collectively,LncDACH1 inhibits lung fibrosis by interacting with SRSF1 to suppress CTNNB1 accumulation,suggesting that LncDACH1 might be a potential therapeutic target for pulmonary fibrosis. | Jian Sun Tongzhu Jin Zhihui Niu Jiayu Guo Yingying Guo Ruoxuan Yang Qianqian Wang Huiying Gao Yuhan Zhang Tianyu Li Wenxin He Zhixin Li Wenchao Ma Wei Su Liangliang Li Xingxing Fan Hongli Shan Haihai Liang | 2022 | Acta Pharmaceutica Sinica B2022，12，9： | 1 |

| 19 | Roadmap of amorphous metal-organic framework for electrochemical energy conversion and storage显示文摘Metal-organic frameworks(MOFs),a well-known coordination network involving potential voids,have attracted attention for energy conversion and storage.As far as is known,MOFs are not only believed to be crystalline.Emerging amorphous MOFs(aMOFs)are starting as supplementary to crystalline MOF(cMOF)in various electrochemical energy fields owing to intrinsic superiorities over crystalline states,greater ease of processing,and distinct physical and chemical properties.aMOFs retain the basic skeletons and connectivity of building units but without any long-range order.Such structural features over long range possess the isotropy without grain boundaries,resulting in fast ions flux and uniform distribution.Simultaneously,distinct shortrange characteristics provide diverse pore confined environment and abundant active sites,and thus accelerate mass transport and charge transfer during electrochemical reactions.Deep understandings and controllable design of aMOF may broaden the opportunities for both scientific researches beyond crystalline materials and practical applications.To date,comprehensive reviews about aMOFs in the fields of energy conversion and storage remain woefully underrepresented.Herein,we summarize the roadmap of aMOF from the development,structural design,opportunity,application,bottleneck,and perspective.In-depth structure-activity relationships with aMOF chemistry are highlighted in the typical electrochemical energy conversion like water oxidation and energy storage,including supercapacitor and battery.The combination of disordered nature at long range and short range,alongside the dynamic structural changes,is promising to reinforce cognition of aMOF domains with MOF versatility,shedding light on the design for efficient electrochemical energy applications via amorphization. | Hang Wang Qi Yang Nan Zheng Xingwu Zhai Tao Xu Zhixin Sun Liang Wu Min Zhou | 2023 | Nano Research2023，16，3： | 1 |
| 20 | Host-guest co-assembly triggered turn-on and ratiometric sensing of berberine and its detoxicating显示文摘Fluorescent sensing for specific detection of berberine is an important issue in view of its potential jeopardization to food safety and human health,but remains less investigated.To the best of our knowledge,there is no fluorescence turn-on and ratiometric sensors available for specific detection of berberine.In this study,calix[4]carbazole(3)has been synthesized and its property of recognizing berberine ha s been evaluated by UV-vis,fluorescence,NMR,DLS and TEM techniques.The results show that 3 selectively recognizes berberine among the tested drugs and detects it with turn-on and ratiometric fluorescence due to their co-assembly nature.Moreover,3 is not only low toxic and can reduce toxicity of berberine to human normal liver L02 cell,but also can release berberine to tumor HepG2 cells at acid micro-environment.It therefore holds a great potential for further exploration。 | Chuanfeng Liu Zhixin Li Hai Yu Naibin Cui Xiaoyu Liao Haibin Zhang Zhengning Shu Peng Yang | 2021 | Chinese Chemical Letters2021，32，4： | 1 |
