| 1 | Depletion of VPS35 attenuates metastasis of hepatocellular carcinoma by restraining the Wnt/PCP signaling pathway显示文摘Vesicle Protein Sorting 35(VPS35)is a novel oncogene that promotes tumor growth through the PI3K/AKT signaling in hepatocellular carcinoma(HCC).However,the role of VPS35 in HCC metastasis and the underlying mechanisms remain largely unclear.In this study,we observed that overexpression of VPS35 enhanced hepatoma cell invasion and metastasis by inducing epithelialemesenchymal transition(EMT)-related gene expression.Conversely,knockout of VPS35 significantly inhibited hepatoma cell migration and invasion.Furthermore,depletion of VPS35 decreased the lung metastasis of HCC in nude mice.By transcriptome analysis,we determined that VPS35 promoted HCC metastasis by activating the Wnt/non-canonical planar cell polarity(PCP)pathway.Mechanistically,VPS35 activated the PCP pathway by regulating membrane sorting and trafficking of Frizzled-2(FZD2)and ROR1 in hepatoma cells.Collectively,our results indicate that VPS35 promotes HCC metastasis via enhancing the Wnt/PCP signaling,thus providing a potential prognostic marker and therapeutic target for HCC. | Yi Liu Haijun Deng Li Liang Guiji Zhang Jie Xia Keyue Ding Ni Tang Kai Wang | 2021 | Genes & Diseases2021，8，2： | 2 |

| 4 | Self-trapped exciton emission in inorganic copper(Ⅰ)metal halides显示文摘The broad emission and high photoluminescence quantum yield of self-trapped exciton(STE)radiative recombination emitters make them an ideal solution for single-substrate,white,solid-state lighting sources.Unlike impurities and defects in semiconductors,the formation of STEs requires a lattice distortion,along with strong electron–phonon coupling,in low electrondimensional materials.The photoluminescence of inorganic copper(Ⅰ)metal halides with low electron-dimensionality has been found to be the result of STEs.These materials were of significant interest because of their leadfree,all-inorganic structures,and high luminous efficiencies.In this paper,we summarize the luminescence characteristics of zero-and one-dimensional inorganic copper(I)metal halides with STEs to provide an overview of future research opportunities. | Boyu ZHANG Xian WU Shuxing ZHOU Guijie LIANG Qingsong HU | 2021 | Frontiers of Optoelectronics2021，14，4： | 1 |
| 5 | Groups-dependent phosphines as the organic redox for point defects elimination in hybrid perovskite solar cells显示文摘Lead(Pb)^(0) and iodine(I)^(0) point defects generated during perovskite solar cell(PSC)fabrication and photoconversion form deep band energy levels as the carriers’recombination centers.These defects not only deteriorate device efficiency,but also facilitate chemical degradation with ion migration,resulting in restricted device lifetime.Herein,we present a novel type of phosphines as the point defects stabilizer for hybrid perovskite solar cells with enhanced performances.Three phosphines with varied side groups of tributyl,trioctyl and triphenyl are exampled as the dopants in perovskite films.The group dependent redox properties were observed in the perovskite film,dependent on their molecular weights and steric hinderances of phosphines.The partially oxidized tributyl phosphine(TBUP)with additional tributyl phosphine oxides(TBPO)is efficient in reduction of lead(Pb)^(0) and iodine(I)^(0) concentrations during the device fabrication and operation.The device with TBUP-TBPO pair showed enhanced power conversion efficiency(PCE)to 20.48% and maintain 91.7% of their initial PCEs after 500 h at 65℃ thermal annealing.Thus,this work presents an efficient route of utilize the phosphine species to reduce point defects in the perovskite film,which promoting further development of novel phosphorous additives with defects stabilization,interface passivation and encapsulation for low-cost solution processed PSCs. | Zhengli Wu Miao Zhang Yifan Liu Yuxi Dou Yinjie Kong Lin Gao Weitao Han Guijie Liang Xiao Li Zhang Fuzhi Huang Yi-Bing Cheng Jie Zhong | 2021 | Journal of Energy Chemistry2021，30，3： | 1 |

| 8 | 2D/2D covalent organic framework/CdS Z-scheme heterojunction for enhanced photocatalytic H_(2) evolution:Insights into interfacial charge transfer mechanism显示文摘Covalent organic frameworks(COFs)with high crystallinity and flexible designability have been consid-ered as promising candidates for photocatalytic hydrogen evolution.However,the existence of unpropi-tious exciton effects in COFs leads to poor charge separation,and thus results in low photocatalytic effi-ciency.Herein,to improve the photoelectron migration efficiency,we designed a 2D/2D organic/inorganic direct Z-scheme COF-based heterojunction(TpTAP/CdS),by the in-situ growing of CdS nanosheets on the COF copolymerized via 2,4,6-tris(4-aminophenyl)-1,3,5-triazine(TAP)and 1,3,5-triformylphloroglucinol(Tp).The femtosecond transient absorption(fs-TA)decay kinetics of TpTAP-COF and TpTAP/CdS further reveal the processes of shallow electron trapping and the recombination of the free photogenerated electron-hole pairs.In particular,the transient absorption traces for TpTAP-COF and TpTAP/CdS normal-ized to the photoinduced absorption peak can effectively verify the Z-scheme charge transfer between TpTAP-COF and CdS,which could enhance the charge mobility and separation,thus reducing the pho-tocorrosion of CdS.Additionally,ultraviolet photoelectron spectroscopy(UPS),in-situ X-ray photoelec-tron spectroscopy(XPS),transient photovoltage measurements,and electron spin resonance(ESR)spec-troscopy further confirm the establishment of the internal electric field(IEF).This work demonstrates the important role of COFs in the construction of 2D/2D organic/inorganic direct Z-scheme heterojunctions and offers a new avenue to explain the criticality of dynamics of the photogenerated carriers for the construction of Z-scheme heterojunctions. | Ruiqi Gao Junxian Bai Rongchen Shen Lei Hao Can Huang Lei Wang Guijie Liang Peng Zhang Xin Li | 2023 | Journal of Materials Science & Technology2023，，6： | 1 |

| 10 | Effects of Strain Channel on Electron Irradiation Tolerance of InP-based HEMT Structures显示文摘The introduction of strain In_(x)Ga_(1-x)As channel with high In content increases the confinement of the two-dimensional electron gas(2DEG)and further improves the high-frequency performance of InGaAs/InAlAs/InP HEMTs.The effect of In_(x)Ga_(1-x)As channel with different In contents on electron irradiation tolerance of InP-based HEMT structures in terms of 2DEG mobility and density has been investigated.The experiment results show that,after the same high electron irradiation dose,the 2DEG mobility and density in InP-based HEMT structures with strain In_(x)Ga_(1-x)As(x>0.53)channel decrease more dramatically than that without strain In_(0.53)Ga_(0.47)As channel.Moreover,the degradation of 2DEG mobility and density becomes more severe as the increase of In content and strain in the In_(x)Ga_(1-x)As channel.The research results can provide some suggestions for the design of radiation-resistant InP-based HEMTs. | FANG Renfeng CAO Wenyu WEI Yanfeng WANG Yin CHEN Chuanliang YAN Jiasheng XING Yan LIANG Guijie ZHOU Shuxing | 2023 | 原子能科学技术2023，57，12： | 0 |
| 11 | Preparation of polyacrylamide based monolith with immobilized pH gradient and its application for protein analysis显示文摘Monolithic materials were prepared in capillaries by in situ polymerization of acrylamide, glycidyl methacrylate and N,N′-memylenebisacrylamid in the presence of trinary porogens, including 1,4-butanediol, dodecanol and dimethyl sulphoxide. With Ampholine immobilized on the monolith by chemical bonding according to their pIs, the monolithic immobilized pH gradient (M-IPG) was prepared, and applied to the separation of four standard proteins. Compared with polyacrylate based M-IPG, the hydrophilicity of the new material was improved. It could not only avoid the adsorption of proteins, but also make the synthesized procedure simple, which showed great potential in the analysis of proteins. | ZHU GuiJie ZHANG WeiBing ZHANG LiHua LIANG Zhen ZHANG YuKui | 2007 | Science China Chemistry2007，50，4： | 0 |
| 12 | Double-ended passivator enables dark-current-suppressed colloidal quantum dot photodiodes for CMOS-integrated infrared imagers显示文摘Lead sulfide(PbS)colloidal quantum dot(CQD)photodiodes integrated with silicon-based readout integrated circuits(ROICs)offer a promising solution for the next-generation short-wave infrared(SWIR)imaging technology.Despite their potential,large-size CQD photodiodes pose a challenge due to high dark currents resulting from surface states on nonpassivated(100)facets and trap states generated by CQD fusion.In this work,we present a novel approach to address this issue by introducing double-ended ligands that supplementally passivate(100)facets of halidecapped large-size CQDs,leading to suppressed bandtail states and reduced defect concentration.Our results demonstrate that the dark current density is highly suppressed by about an order of magnitude to 9.6 nA cm^(2) at^(-1)0 mV,which is among the lowest reported for PbS CQD photodiodes.Furthermore,the performance of the photodiodes is exemplary,yielding an external quantum efficiency of 50.8%(which corresponds to a responsivity of 0.532 A W^(-1))and a specific detectivity of 2.5×10^(12) Jones at 1300 nm.By integrating CQD photodiodes with CMOS ROICs,the CQD imager provides high-resolution(640512)SWIR imaging for infrared penetration and material discrimination. | Peilin Liu Shuaicheng Lu Jing Liu Bing Xia Gaoyuan Yang Mo Ke Xuezhi Zhao Junrui Yang Yuxuan Liu Ciyu Ge Guijie Liang Wei Chen Xinzheng Lan Jianbing Zhang Liang Gao Jiang Tang | 2024 | InfoMat2024，6，1： | 0 |
| 13 | Site occupation and energy transfer in full color emitting phosphor Ba2Ca(BO3)2:Ce3+(K+),Eu^(2+),Mn2+显示文摘White light-emitting diodes(WLEDs)fabricated by single-phase full color emitting phosphor are an emerging solution for health lighting.The crystallographic site occupation of activators in a proper host lattice is crucial for sophisticated design of such phosphor.Here,we report a high quality white lightemitting phosphor Ba_(2)Ca(BO_(3))_(2):Ce^(3+)(K^(+)),Eu^(2+),Mn^(2+)with spectral distribution covering whole visible region.Blue light emission originates from Ce3+ions occupying preferentially Ba^(2+)site by controlling synthesis conditions.Green and red lights are obtained from Eu^(2+)occupying Ba2+(and Ca)site and Mn2+occupying Casite,respectively.In this triple-doped phosphor,strong red emission with a low concentration of Mn2+is realized by the efficient energy transfer from Ce3+and Euto Mn.Furthermore,high quality white light is accomplished by properly tuning the relative doping amount of Ce^(3+)(K^(+))/Eu^(2+)/Mn^(2+)based on efficient simultaneous energy transfer.The results indicate that Ba_(2)Ca(BO_(3))_(2):Ce^(3+)(K^(+)),Eu^(2+),Mn^(2+)is a promising white light-emitting phosphor in WLEDs application. | Qingsong Hu Zaifa Pan Guijie Liang | 2022 | Journal of Rare Earths2022，40，11： | 0 |
