1Electric-field-controlled superconductor–ferromagnetic insulator transition显示文摘Superconductivity beyond electron-phonon mechanism is always twisted with magnetism. Based on a new field-effect transistor with solid ion conductor as the gate dielectric(SIC-FET), we successfully achieve an electric-field-controlled phase transition between superconductor and ferromagnetic insulator in(Li,Fe)OHFeSe. A dome-shaped superconducting phase with optimal T_c of 43K is continuously tuned into a ferromagnetic insulating phase, which exhibits an electric-field-controlled quantum critical behavior. The origin of the ferromagnetism is ascribed to the order of the interstitial Fe ions expelled from the(Li,Fe)OH layers by gating-controlled Li injection. These surprising findings offer a unique platform to study the relationship between superconductivity and ferromagnetism in Fe-based superconductors. This work also demonstrates the superior performance of the SIC-FET in regulating physical properties of layered unconventional superconductors.Likuan Ma Bin Lei Naizhou Wang Kaishuai Yang Dayong Liu Fanbao Meng Chao Shang Zeliang Sun Jianhua Cui Changsheng Zhu Tao Wu Zhe Sun Liangjian Zou Xianhui Chen 2019Science Bulletin2019,64,10:4
2Magnetic-field enhanced high-thermoelectric performance in topological Dirac semimetal Cd3As2 crystal显示文摘Thermoelectric materials can be used to convert heat to electric power through the Seebeck effect. We study magneto-thermoelectric figure of merit(ZT) in three-dimensional Dirac semimetal Cd_3As_2 crystal.It is found that enhancement of power factor and reduction of thermal conductivity can be realized at the same time through magnetic field although magnetoresistivity is greatly increased. ZT can be highly enhanced from 0.17 to 1.1 by more than six times around 350 K under a perpendicular magnetic field of 7 T. The huge enhancement of ZT by magnetic field arises from the linear Dirac band with large Fermi velocity and the large electric thermal conductivity in Cd_3As_2. Our work paves a new way to greatly enhance the thermoelectric performance in the quantum topological materials.Honghui Wang Xigang Luo Weiwei Chen Naizhou Wang Bin Lei Fanbao Meng Chao Shang Likuan Ma Tao Wu Xi Dai Zhengfei Wang Xianhui Chen 2018Science Bulletin2018,63,7:4
3Oncoprotein HBXIP promotes tumorigenesis through MAPK/ERK pathway activation in non-small cell lung cancer显示文摘Objective:The oncoprotein,hepatitis B X-interacting protein(HBXIP),has been reported to play an important role in human malignancies.However,its functions in non-small cell lung cancer(NSCLC)are poorly understood.The goal of the present study was to identify the role of HBXIP in the regulation of NSCLC development.Methods:The level of HBXIP expression in NSCLC tissue was assessed by immunohistochemical and Western blot analyses,and its relationships with clinicopathological features and outcomes were statistically evaluated.The effects of HBXIP on NSCLC cell progression were assessed through cell viability,colony formation,and flow cytometry analyses in vitro.The mechanism by which HBXIP regulated the MAPK pathway was studied by Western blot,immunofluorescence,and immunoprecipitation assays.In addition,in vivo experiments were performed to evaluate the progression of NSCLC and ERK signaling pathway activation after HBXIP knockdown.Results:HBXIP was overexpressed in human NSCLC and was correlated with the invasiveness of NSCLC.The high expression of HBXIP in NSCLC was significantly correlated with gender(P=0.033),N stage(P=0.002),and tumor-node-metastasis stage(P=0.008).In vitro experiments using an NSCLC cell line revealed that HBXIP knockdown resulted in the suppression of cell proliferation and colony formation,which was consistent with the enhanced cell cycle arrest in G1 phase.The results of a mechanistic investigation suggested that binding of HBXIP to MEK1 protein promoted MAPK/ERK signaling pathway activation in NSCLC by preventing the proteasome-mediated degradation of MEK1.In addition,the results obtained using in vivo subcutaneous tumor xenografts confirmed that HBXIP deficiency decreased MEK1 protein levels and NSCLC tumor growth.Conclusions:Taken together,our results showed that the HBXIP-MEK interaction promoted oncogenesis via the MAPK/ERK pathway,which may serve as a novel therapeutic target for cancers in which MAPK/ERK signaling is a dominant feature.Jun Zhang Bei Sun Xianhui Ruan Xiukun Hou Jingtai Zhi Xiangrui Meng Xiangqian Zheng Ming Gao 2021Cancer Biology & Medicine2021,18,1:3
4Coaxing Polysaccharide Granules into Supramolecular Biocolloidal Additives for Papermaking显示文摘In light of developments in polysaccharide-based sustainable processes involving supramolecular interactions,we herein present our findings pertaining to coaxing polysaccharide granules into functional supramolecular biocolloids.Translucent biocolloidal dispersions containing various forms of starch are facilely designable,essentially built upon complexation between disassembled native cornstarch granules and amphiphilic ligands.Oily moieties of guest molecules are dynamically attractable into cavities of helical structures,with cationic groups pointing toward the bulk phase.This noncovalent attraction can generate core-shell biocolloidal particles.The significantly higher gelatinizability of freeze-dried biocolloids in contrast to native cornstarch granules is attributable to complex formation,and a homogenous dispersion is readily formable at room temperature.Our results also show biocolloids'ligand-related antibacterial activity.The use of biocolloids as wet-end additives for biofiber assemblies(cellulosic paper)can enhance mechanical strength,fines retention,and filler bondability.Supramolecular biocolloids with positively charged,translucent,easily gelatinizable,antibacterial,and polysaccharide-bondable functionalities would find tailorable use in the paper industry.Yongsheng Wang Wenyuan Zhu Xueren Qian Meiyun Zhang Shunxi Song Chuyan Jing Zhengren Meng Shiyu Xu Xianhui An Xiujie Huang Jing Shen 2020Paper And Biomaterials2020,5,2:1
5High performance 0.9LiMnPO4-0.1LiFePO4/C composite显示文摘The rate performance of lithium manganese phosphate is seriously tarnished by its sluggish surface kinetics,which could be addressed by LiFePO4-surface coating.For a higher energy output,here we explore thinner coating layers with 10%and 5%LiFePO4 via the lab-developed DMSO assisted method.The core-shell structured 0.9LiMnPO4-0.1LiFePO4/C maintains a high specific capacity,153,148 and 140 mA hg-1 under 0.1,1 and 5 C respectively,which are the best results for this composition till date.As for 0.95Li MnPO4-0.05 LiFePO4/C,the discharge capacity is lower than 110 mA hg-1 even in 0.1 C,which cannot meet the requirements of practical application.Our approaches push the manganese ratio of LiMnPO4-based composite to 90%from 80%,further improving the energy-density of the olivine phosphates.LIU Jian ZHANG XianHui YANG WenChao LIU Meng REN ZhongMin ZHANG ShengQi WANG DeYu 2020Science China(Technological Sciences)2020,63,6:1

7Crossover effects of transition metal ions in high-voltage lithium metal batteries显示文摘Enhancing the cut-off voltage of high-nickel layered oxide cathodes is an efficient way to obtain higher energy density of lithiummetal batteries(LMBs).However,the phase transition of the cathode materials and the uncontrolled decomposition of the electrolytes at high voltage can lead to irreversible dissolution of transition metal ions,which might cause the crossover effects on the lithium metal anodes.Nonetheless,the mechanism and electrolyte dependence of the crossover effects for Li metal anodes are still unclear.Herein,we investigate the crossover effects between LiNi_(0.8)Mn_(0.1)Co_(0.1)O_(2)and Li-metal anode in two electrolyte systems.For ether-based electrolyte,its poor oxidation stability results in massive dissolution of transition metal ions,leading to dendrite growth on anode and rapid cells failure.Conversely,ester-based electrolyte exhibits good electrochemical performances at 4.5 V with little crossover effect.This study provides an idea for electrolyte systems selection for high-voltage LMBs,and verifies that the crossover effect should not be neglected in LMBs.Wanxia Li Yulin Jie Yunhua Chen Ming Yang Yawei Chen Xinpeng Li Youzhang Guo Xianhui Meng Ruiguo Cao Shuhong Jiao 2023Nano Research2023,16,6:0
8Magnetic field-induced electronic phase transition in the Dirac semimetal state of black phosphorus under pressure显示文摘Different instabilities have been confirmed to exist in the three-dimensional(3D) electron gas when it is confined to the lowest Landau level in the extreme quantum limit. The recently discovered 3D topological semimetals offer a good platform to explore these phenomena due to the small sizes of their Fermi pockets, which means the quantum limit can be achieved at relatively low magnetic fields. In this work, we report the high-magnetic-field transport properties of the Dirac semimetal state in pressurized black phosphorus. Under applied hydrostatic pressure, the band structure of black phosphorus goes through an insulator-semimetal transition. In the high pressure topological semimetal phase, anomalous behaviors are observed on both magnetoresistance and Hall resistivity beyond the relatively low quantum limit field, which is demonstrated to indicate the emergence of an exotic electronic state hosting a density wave ordering. Our findings bring the first insight into the electronic interactions in black phosphorus under intense field.Zeliang Sun Ziji Xiang Zhongyi Wang Jinglei Zhang Long Ma Naizhou Wang Chao Shang Fanbao Meng Liangjian Zou Yuanbo Zhang Xianhui Chen 2018Science Bulletin2018,63,23:0
