2A perspective on the electrocatalytic conversion of carbon dioxide to methanol with metallomacrocyclic catalysts显示文摘Electrocatalytic carb on dioxide reducti on(CO_(2)R)presents a promising route to establish zero-e mission carb on cycle and store in termittent ren ewable energy into chemical fuels for steady energy supply.Methanol is an ideal energy carrier as alternative fuels and one of the most important commodity chemicals.Nevertheless,methanol is currently mainly produced from fossil-based syngas,the production of which yields tremendous carb on emission globally.Direct CO_(2)R towards metha nol poses great potential to shift the paradigm of methanol production.In this perspective,we focus our discussions on producing methanol from electrochemical CO_(2)R,using metallomacrocyclic molecules as the model catalysts.We discuss the motivation of having methanol as the sole CO_(2)R product,the documented application of metallomacrocyclic catalysts for CO_(2)R,and recent advance in catalyzing CO_(2) to methanol with cobalt phthalocyanine-based catalysts.We attempt to understand the key factors in determining the activity,selectivity,and stability of electrocatalytic CO_(2)-to-methanol conversion,and to draw mechanistic insights from existing observations.Finally,we identify the challenges hindering methanol electrosynthesis directly from CO_(2) and some intriguing directions worthy of further investigation and exploration.Xinyan Liu Bo-Quan Li Bing Ni Lei Wang Hong-Jie Peng 2022Journal of Energy Chemistry2022,31,1:3
3阵风锋和中尺度气团边界相互作用的对流初生机制的一个案例研究(英文)显示文摘在研究阵风锋和中尺度气团边界相互作用触发对流初生的这篇文章中,研究了两种对流层边界一一阵风锋和中尺度气团边界共同对对流初生的影响。该对流初生现象首先由观测发现,雷达和自动站观测显示阵风锋前方有一个中尺度气团边界存在,在该边界上温湿变化较大,风场存在辐合。在阵风锋与该中尺度气团边界相互靠近的过程中,两者之间的辐合区域产生了新生对流。为了更清楚地研究该新生对流的初生机制,本研究采用高分辨率的雷达四维变分分析系统同化雷达和自动站资料,融合中尺度模式结果。同化结果分析表明,阵风锋和中尺度气团边界之间辐合抬升加强,被抬升的暖湿气团超过了自由对流高度,产生了新生对流。这对提高新生对流的临近预报和预警可能具有有益启示。CUI Xinyan QIN Rui CHEN Mingxuan HAN Lei 2019Atmospheric and Oceanic Science Letters2019,12,5:2
4Spontaneous movement of a retrotransposon generated genic dominant male sterility providing a useful tool for rice breeding显示文摘Male sterility in plants provides valuable breeding tools in germplasm innovation and hybrid crop production.However,genetic resources for dominant genic male sterility,which hold great promise to facilitate breeding processes,are extremely rare in natural germplasm.Here we characterized the Sanming Dominant Genic Male Sterility in rice and identified the gene SDGMS using a map-based cloning approach.We found that spontaneous movement of a 1978-bp long terminal repeat(LTR)retrotransposon into the promoter region of the SDGMS gene activates its expression in anther tapetum,which causes abnormal programmed cell death of tapetal cells resulting in dominant male sterility.SDGMS encodes a ribosome inactivating protein showing N-glycosidase activity.The activation of SDGMS triggers transcription reprogramming of genes responsive to biotic stress leading to a hypersensitive response which causes sterility.The results demonstrate that an ectopic gene activation by transposon movement can give birth to a novel trait which enriches phenotypic diversity with practical utility.Conghao Xu Yifeng Xu Zhengji Wang Xiaoyu Zhang Yuying Wu Xinyan Lu Hongwei Sun Lei Wang Qinglu Zhang Qinghua Zhang Xianghua Li Jinghua Xiao Xu Li Mingfu Zhao Yidan Ouyang Xianbo Huang Qifa Zhang 2023National Science Review2023,10,9:1
5Genetic lineage tracing identifies cardiac mesenchymal-to-adipose transition in an arrhythmogenic cardiomyopathy model显示文摘Arrhythmogenic cardiomyopathy(ACM)is one of the most common inherited cardiomyopathies,characterized by progressive fibrofatty replacement in the myocardium.However,the cellular origin of cardiac adipocytes in ACM remains largely unknown.Unraveling the cellular source of cardiac adipocytes in ACM would elucidate the underlying pathological process and provide a potential target for therapy.Herein,we generated an ACM mouse model by inactivating desmosomal gene desmoplakin in cardiomyocytes;and examined the adipogenic fates of several cell types in the disease model.The results showed that SOX9^(+),PDGFRa^(+),and PDGFRb^(+)mesenchymal cells,but not cardiomyocytes or smooth muscle cells,contribute to the intramyocardial adipocytes in the ACM model.Mechanistically,Bmp4 was highly expressed in the ACM mouse heart and functionally promoted cardiac mesenchymal-to-adipose transition in vitro.Xinyan Huang Lei Yan Jufeng Meng Nanbo Liu Shuoji Zhu Zhen Jiang Shan Kou Teng Feng Chao-Po Lin Bin Zhou Juan Tang Ping Zhu Hui Zhang 2023Science China(Life Sciences)2023,66,1:1
6Variable universe fuzzy control of walking stability for flying‐walking power line inspection robot based on multi‐work conditions显示文摘To address complex work conditions incredibly challenging to the stability of power line inspection robots,we design a walking mechanism and propose a variable universe fuzzy control(VUFC)method based on multi‐work conditions for flying‐walking power line inspection robots(FPLIRs).The contributions of this paper are as follows:(1)A flexible pressing component is designed to improve the adaptability of the FPLIR to the ground line slope.(2)The influence of multi‐work conditions on the FPLIR's walking stability is quantified using three condition parameters(i.e.,slope,slipping degree and swing angle),and their measurement methods are proposed.(3)The VUFC method based on the condition parameters is proposed to improve the walking stability of the FPLIR.Finally,the effect of the VUFC method on walking stability of the FPLIR is teste.The experimental results show that the maximum climbing angle of the FPLIR reaches 29.1°.Compared with the constant pressing force of 30 N,the average value of slipping degree is 0.93°,increasing by 35%.The maximum and average values of robot's swing angle are reduced by 46%and 54%,respectively.By comparing with fuzzy control,the VUFC can provide a more reasonable pressing force while maintaining the walking stability of the FPLIR.The proposed walking mechanism and the VUFC method significantly improve the stability of the FPLIR,providing a reference for structural designs and stability controls of inspection robots.Zhaojun Li Xinyan Qin Jin Lei Jie Zhang Huidong Li Bo Li Yanqi Wang Dexin Wang 2022IET Cyber-Systems and Robotics2022,4,3:1
7Degradation kinetics of functional components of honeysuckle flowers during controlled-atmosphere heat pump drying显示文摘To investigate the change law of functional components and exterior color of honeysuckle flowers(HF)during controlled-atmosphere heat pump drying,nitrogen was used as drying medium in this study to reduce the oxygen concentration.The influences of drying temperature,HF’s loading amount and oxygen concentration on chlorogenic acid content,cynaroside content and L value(on behalf of browning degree)were explored,and the degradation kinetics models of chlorogenic acid and cynaroside were constructed.The results showed that chlorogenic acid content,cynaroside content and L value decreased with the rise of temperature,HF’s loading amount and oxygen concentration.The degradation kinetics models of chlorogenic acid and cynaroside during the drying process were established through introducing an exponent r related to time t in the first order reaction kinetics equation.The models had good fitting precision and can be used to predict the degradation law of chlorogenic acid and cynaroside.Luo Lei Yang Bin Zhu Wenxue Ren Guangyue Duan Xu Kang Xinyan 2016International Journal of Agricultural and Biological Engineering2016,9,4:1

9Water scaling predication for typical sandstone geothermal reservoirs in the Xi'an Depression显示文摘The Xi'an Depression in the Guanzhong Basin of western China has been suggested to contain geothermal resources that could aid China in achieving carbon neutrality and optimizing energy structure.However,the high concentration of total dissolved solids(TDS)and scale-forming ions in geothermal water from the depression causes severe scaling problems in harvesting geothermal energy.To reduce scale-related problems,accurate identification of scale types and prediction of scaling during geothermal energy utilization are crucial.This study starts with identifying the types and trends of scaling in the study area,using index-based discriminant methods and hydrogeochemical simulation to calculate and analyze the mineral saturation index of water samples from some wellheads and of reconstructed fluid samples of geothermal reservoirs.The results indicate that the scales are mostly calcium carbonate scales rather than sulfate scales as a result of temperature changes.Several portions of the geothermal water systems are found to have distinct mineral scaling components.Quartz and chalcedony are formed in low temperature areas,while carbonate minerals are in high temperature areas.Despite the low iron content of geothermal water samples from the study area,scaling is very common due to scaling-prone iron minerals.The findings can be used to evaluate geothermal drainage systems and guide anti-scaling during geothermal energy utilization in similar settings.Shuai Ma Yinke Yang Xinyan Lei Bin Yue 2023Energy Geoscience2023,4,4:0
10Stabilizing zinc anode using zeolite imidazole framework functionalized separator for durable aqueous zinc-ion batteries显示文摘Aqueous zinc-ion batteries(AZIBs) hold great promise as a viable alternative to lithium-ion batteries owing to their high energy density and environmental friendliness.However,AZIBs are consistently plagued by the formation of zinc dendrites and concurrent side reactions,which significantly diminish their overall service life,In this study,the glass fiber separator(GF) is modified using zeolite imidazole salt framework-8(ZIF-8),enabling the development of efficient AZIBs.ZIF-8,which is abundant in nitrogen content,efficiently regulates the desolvation of [Zn(H_(2)O)_(6)]^(2+) to inhibit hydrogen production.Moreover,it possesses abundant nanochannels that facilitate the uniform deposition of Zn~(2+) via a localized action,thereby hindering the formation of dendrites.The insulating properties of ZIF-8 help prevent Zn^(2+) and water from trapping electron reduction at the layer surface,which reduces corrosion of the zinc anode.Consequently,ZIF-8-GF achieves the even transport of Zn^(2+) and regulates the homogeneous deposition along the Zn(002) crystal surface,thus significantly enhancing the electrochemical performance of the AZIBs,In particular,the Zn|Zn symmetric cell with the ZIF-8-GF separator delivers a stable cycle life at0.5 mA cm^(-2) of 2300 h.The Zn|ZIF-8-GF|MnO_(2) cell exhibits reduced voltage polarization while maintaining a capacity retention rate(93.4%) after 1200 cycles at 1.2 A g^(-1) The unique design of the modified diaphragm provides a new approach to realizing high-performance AZIBs.Weisong Zhang Xinyan Zhu Ling Kang Ziyu Peng Jing Zhu Liang Pan Lei Dai Shude Liu Ling Wang Yongguang Liu Zhangxing He 2024Journal of Energy Chemistry2024,90,3:0
11RING finger 138 deregulation distorts NF-κB signaling and facilities colitis switch to aggressive malignancy显示文摘Prolonged activation of nuclear factor(NF)-кB signaling significantly contributes to the development of colorectal cancer(CRC).New therapeutic opportunities are emerging from targeting this distorted cell signaling transduction.Here,we discovered the critical role of RING finger 138(RNF138)in CRC tumorigenesis through regulating the NF-кB signaling,which is independent of its Ubiquitin-E3 ligase activity involved in DNA damage response.RNF138^(−/−) mice were hyper-susceptible to the switch from colitis to aggressive malignancy,which coincided with sustained aberrant NF-кB signaling in the colonic cells.Furthermore,RNF138 suppresses the activation of NF-кB signaling pathway through preventing the translocation of NIK and IKK-Beta Binding Protein(NIBP)to the cytoplasm,which requires the ubiquitin interaction motif(UIM)domain.More importantly,we uncovered a significant correlation between poor prognosis and the downregulation of RNF138 associated with reinforced NF-кB signaling in clinical settings,raising the possibility of RNF138 dysregulation as an indicator for the therapeutic intervention targeting NF-кB signaling.Using the xenograft models built upon either RNF138-dificient CRC cells or the cells derived from the RNF138-dysregulated CRC patients,we demonstrated that the inhibition of NF-кB signaling effectively hampered tumor growth.Overall,our work defined the pathogenic role of aberrant NF-кB signaling due to RNF138 downregulation in the cascade events from the colitis switch to colonic neoplastic transformation and progression,and also highlights the possibility of targeting the NF-кB signaling in treating specific subtypes of CRC indicated by RNF138-ablation.Yalan Lu Rong Huang Jianming Ying Xingchen Li Tao Jiao Lei Guo Haitao Zhou Han Wang Amannisa Tuersuntuoheti Jianmei Liu Qichen Chen Yanhong Wang Luying Su Changyuan Guo Fu Xu Ziyi Wang Yan Lu Kai Li Junbo Liang Zhen Huang Xiao Chen Jinjie Yao Hanjie Hu Xiaowen Cheng Yufeng Wan Xinyan Chen Ning Zhang Shiying Miao Jianqiang Cai Linfang Wang Changzheng Liu Wei Song Hong Zhao 2022Signal Transduction and Targeted Therapy2022,7,7:0
12IQ67 DOMAIN protein 21 is critical for indentation formation in pavement cell morphogenesis显示文摘In plants, cortical microtubules anchor to the plasma membrane in arrays and play important roles in cell shape. However, the molecular mechanism of microtubule binding proteins, which connect the plasma membrane and cortical microtubules in cell morphology remains largely unknown. Here, we report that a plasma membrane and microtubule duallocalized IQ67 domain protein, IQD21, is critical for cotyledon pavement cell(PC) morphogenesis in Arabidopsis. iqd21 mutation caused increased indentation width, decreased lobe length, and similar lobe number of PCs, whereas IQD21 overexpression had a different effect on cotyledon PC shape. Weak overexpression led to increased lobe number, decreased indentation width, and similar lobe length, while moderate or great overexpression resulted in decreased lobe number, indentation width, and lobe length of PCs. Live-cell observations revealed that IQD21 accumulation at indentation regions correlates with lobe initiation and outgrowth during PC development. Cell biological and genetic approaches revealed that IQD21 promotes transfacial microtubules anchoring to the plasma membrane via its polybasic sites and bundling at the indentation regions in both periclinal and anticlinal walls. IQD21 controls cortical microtubule organization mainly through promoting Katanin 1-mediated microtubule severing during PC interdigitation. These findings provide the genetic evidence that transfacial microtubule arrays play a determinant role in lobe formation, and the insight into the molecular mechanism of IQD21 in transfacial microtubule organization at indentations and puzzle-shaped PC development.Xinhua Feng Shujuan Pan Haifu Tu Junjie Huang Chuanlei Xiao Xin Shen Lei You Xinyan Zhao Yongqiang Chen Danyun Xu Xiaolu Qu Honghong Hu 2023Journal of Integrative Plant Biology2023,65,3:0
13Isogenic human pluripotent stem cell disease models reveal ABRA deficiency underlies cTnT mutation-induced familial dilated cardiomyopathy显示文摘Dear Editor,Dilated cardiomyopathy(DCM)is a common form of inherited cardiomyopathy.In the past decades,single mutations in various genes encoding sarcomeric,cytoskeletal,and channel proteins etc.have been found to be associated with DCM(Hershberger et al.,2013;McNally and Mestroni,2017).However,the mechanisms how single mutations in sarcomeric or structural genes lead to the disease remain elusive.An interesting phenomenon often seen in familial cardiomyopathy is that different single mutations on the same gene can cause either DCM or hypertrophic cardiomyopathy(HCM)(Kathiresan and Srivastava,2012),which exhibit almost opposite disease phenotypes.DCM is characterized by thinned myocardium and septum,ventricular chamber dilation,and systolic dysfunction(Jefferies and Towbin,2010;McNally and Mestroni,2017),while HCM exhibits thickened myocardium and septum,reduced ventricular chamber,and diastolic dysfunction(Richard et al.,2003).At the cellular level,HCM cardiomyocytes exhibit concentric hypertrophy characterized by assembly of myofilaments in parallel and widening of the myocytes.In contrast,DCM cardiomyocytes show eccentric hypertrophy,with assembly of the myofilaments in series and myocyte elongation(Kehat and Molkentin,2010).Bin Li Yongkun Zhan Qianqian Liang Chen Xu Xinyan Zhou Huanhuan Cai Yufan Zheng Yifan Guo Lei Wang Wenqing Qiu Baiping Cui Chao Lu Ruizhe Qian Ping Zhou Haiyan Chen Yun Liu Sifeng Chen Xiaobo Li Ning Sun 2022Protein & Cell2022,13,1:0
14MTC: A Multi-Task Model for Encrypted Network Traffic Classification Based on Transformer and 1D-CNN显示文摘Traffic characterization(e.g.,chat,video)and application identifi-cation(e.g.,FTP,Facebook)are two of the more crucial jobs in encrypted network traffic classification.These two activities are typically carried out separately by existing systems using separate models,significantly adding to the difficulty of network administration.Convolutional Neural Network(CNN)and Transformer are deep learning-based approaches for network traf-fic classification.CNN is good at extracting local features while ignoring long-distance information from the network traffic sequence,and Transformer can capture long-distance feature dependencies while ignoring local details.Based on these characteristics,a multi-task learning model that combines Transformer and 1D-CNN for encrypted traffic classification is proposed(MTC).In order to make up for the Transformer’s lack of local detail feature extraction capability and the 1D-CNN’s shortcoming of ignoring long-distance correlation information when processing traffic sequences,the model uses a parallel structure to fuse the features generated by the Transformer block and the 1D-CNN block with each other using a feature fusion block.This structure improved the representation of traffic features by both blocks and allows the model to perform well with both long and short length sequences.The model simultaneously handles multiple tasks,which lowers the cost of training.Experiments reveal that on the ISCX VPN-nonVPN dataset,the model achieves an average F1 score of 98.25%and an average recall of 98.30%for the task of identifying applications,and an average F1 score of 97.94%,and an average recall of 97.54%for the task of traffic characterization.When advanced models on the same dataset are chosen for comparison,the model produces the best results.To prove the generalization,we applied MTC to CICIDS2017 dataset,and our model also achieved good results.Kaiyue Wang Jian Gao Xinyan Lei 2023Intelligent Automation & Soft Computing2023,,7:0
15Fast processing nylon mesh by surface diffuse atmospheric plasma for large-area oil/water separation显示文摘In recent years,numerous studies have been reported for oil/water separation,such as superoleophilic materials for oil absorption and underwater superoleophobic membranes for continuous separation.However,for the recovery of oil slick pollution on near-shore ocean surface caused by various reasons,large area and fast availability of used materials are needed to be considered.Herein,we report an efficient and environmentally friendly method to fast process nylon mesh by surface diffuse atmospheric plasma(SDAP)for large-area oil/water separation.Nylon mesh is funcionalized by atmospheric plasma to generate micro/nano composite structures on the surface,resulting in superhydrophilicity and underwater superoleophobicity within only seconds.The pre-wetted modified nylon mesh can achieve high efficiency(>99.9%)and circulating water flux(~30,000 L·m^(-2)·h^(-1)),with high intrusion pressure(~3 kPa)and universality in oil/water separation.Regular plasma unconditionally generated in the atmosphere with the merit of efficiently functionalizing surface has the potential of large-area materials treatment.This study might take one step further for large-area industrial oily wastewater recovery and even oil slicks collection in near-shore water bodies.Linfeng Yang Yaping Feng Zengyi He Xinyan Jiang Xianfeng Luo Haoyu Dai Lei Jiang 2023Nano Research2023,16,7:0
16Covalent Organic Framework with 3D Ordered Channel and Multi-Functional Groups Endows Zn Anode with Superior Stability显示文摘Achieving a highly robust zinc(Zn)metal anode is extremely important for improving the performance of aqueous Zn-ion batteries(AZIBs)for advancing“carbon neutrality”society,which is hampered by the uncontrollable growth of Zn dendrite and severe side reactions including hydrogen evolution reaction,corrosion,and passivation,etc.Herein,an interlayer containing fluorinated zincophilic covalent organic framework with sulfonic acid groups(COF-S-F)is developed on Zn metal(Zn@COF-S-F)as the artificial solid electrolyte interface(SEI).Sulfonic acid group(-SO_(3)H)in COF-S-F can effectively ameliorate the desolvation process of hydrated Zn ions,and the three-dimensional channel with fluoride group(-F)can provide interconnected channels for the favorable transport of Zn ions with ion-confinement effects,endowing Zn@COF-S-F with dendrite-free morphology and suppressed side reactions.Consequently,Zn@COF-S-F symmetric cell can stably cycle for 1,000 h with low average hysteresis voltage(50.5 m V)at the current density of 1.5 m A cm^(-2).Zn@COF-S-F|Mn O_(2)cell delivers the discharge specific capacity of 206.8 m Ah g^(-1)at the current density of 1.2 A g^(-1)after 800 cycles with high-capacity retention(87.9%).Enlightening,building artificial SEI on metallic Zn surface with targeted design has been proved as the effective strategy to foster the practical application of high-performance AZIBs.Bin Li Pengchao Ruan Xieyu Xu Zhangxing He Xinyan Zhu Liang Pan Ziyu Peng Yangyang Liu Peng Zhou Bingan Lu Lei Dai Jiang Zhou 2024Nano-Micro Letters2024,16,4:0
