1Synthesis, characteristics of hierarchical EU-1 zeolite for xylene isomerization probe reaction显示文摘Introduced a method of synthesizing hierarchical EU-1 zeolite with organosilanes as additive, and studied the influences of following different kinds of organosilanes on the synthesis of hierarchical EU-1 zeolite: γ-glycidoxy propyl trimethoxy silane(GPTMS), N-β-(aminoethyl)-γ-aminopropyl methyl dimethoxyl silane(APAEDMS),and N-(β-aminoethyl)-γ-aminopropyl dimethoxyl(ethyoxyl) silane(TMPED). The hierarchical EU-1 samples were characterized by XRD, SEM, N_2 adsorption, FT-IR and NH_3-TPD to analyze the crystallinity, morphology, surface area, pore size distribution and acidity. The results showed that hierarchical EU-1 zeolites were successfully synthesized; organosilanes have great influence on crystal morphology of EU-1 zeolites; the exterior surface area of hierarchical EU-1 zeolite, which synthesized with organosilanes(APAEDMS) adding into synthesis system, increased by 62.1% and mesopore volume increased by 129.1% compared with conventional EU-1 zeolites, thus can reduce the diffusional restriction markedly in catalytic reaction. The catalytic performance of hierarchical EU-1zeolites were evaluated in m-xylene isomerization on fixed bed reactor. The catalytic data showed that the isomerization activity PX/X of the hierarchical EU-1 zeolites reached around 24.09% in theoretical thermodynamic equilibrium from 23.83%, and the selectivity of C_8 aromatic hydrocarbon increased from 75.16% to 84.87%. The conversion of p-xylene increased from 16.30% to 18.41%.Xiaofeng Li Pengchao Ren Yanting Zhang Xiaozhen Liu Xiaotao Sun Meng Gao Miaojuan Jia Zhiping Lü Tao Dou 2016Chinese Journal of Chemical Engineering2016,24,11:4
2SPDEF suppresses head and neck squamous cell carcinoma progression by transcriptionally activating NR4A1显示文摘SAM pointed domain containing E26 transformation-specific transcription factor(SPDEF)plays dual roles in the initiation and development of human malignancies.However,the biological role of SPDEF in head and neck squamous cell carcinoma(HNSCC)remains unclear.In this study,the expression level of SPDEF and its correlation with the clinical parameters of patients with HNSCC were determined using TCGA-HNSC,GSE65858,and our own clinical cohorts.CCK8,colony formation,cell cycle analysis,and a xenograft tumor growth model were used to determine the molecular functions of SPDEF in HNSCC.ChIP-qPCR,dual luciferase reporter assay,and rescue experiments were conducted to explore the potential molecular mechanism of SPDEF in HNSCC.Compared with normal epithelial tissues,SPDEF was significantly downregulated in HNSCC tissues.Patients with HNSCC with low SPDEF mRNA levels exhibited poor clinical outcomes.Restoring SPDEF inhibited HNSCC cell viability and colony formation and induced G0/G1 cell cycle arrest,while silencing SPDEF promoted cell proliferation in vitro.The xenograft tumor growth model showed that tumors with SPDEF overexpression had slower growth rates,smaller volumes,and lower weights.SPDEF could directly bind to the promoter region of NR4A1 and promoted its transcription,inducing the suppression of AKT,MAPK,and NF-κB signaling pathways.Moreover,silencing NR4A1 blocked the suppressive effect of SPDEF in HNSCC cells.Here,we demonstrate that SPDEF acts as a tumor suppressor by transcriptionally activating NR4A1 in HNSCC.Our findings provide novel insights into the molecular mechanism of SPDEF in tumorigenesis and a novel potential therapeutic target for HNSCC.Yanting Wang Xianyue Ren Weiyu Li Ruoyan Cao Suyang Liu Laibo Jiang Bin Cheng Juan Xia 2021International Journal of Oral Science2021,13,4:3
3Key Recovery Against 3DES in CPU Smart Card Based on Improved Correlation Power Analysis显示文摘The security of CPU smart cards,which are widely used throughout China,is currently being threatened by side-channel analysis.Typical countermeasures to side-channel analysis involve adding noise and filtering the power consumption signal.In this paper,we integrate appropriate preprocessing methods with an improved attack strategy to generate a key recovery solution to the shortcomings of these countermeasures.Our proposed attack strategy improves the attack result by combining information leaked from two adjacent clock cycles.Using our laboratory-based power analysis system,we verified the proposed key recovery solution by performing a successful correlation power analysis on a Triple Data Encryption Standard(3DES)hardware module in a real-life 32-bit CPU smart card.All 112 key bits of the 3DES were recovered with about 80 000 power traces.Yanting Ren Liji Wu Hexin Li Xiangyu Li Xiangmin Zhang An Wang Hongyi Chen 2016Tsinghua Science and Technology2016,21,2:3

5Band alignment and polarization engineering inκ-Ga_(2)O_(3)/GaN ferroelectric heterojunction显示文摘Ferroelectric-semiconductor heterostructures offer an alternative strategy to manipulate polarization towards advanced devices with engineered functionality and improved performance.In this work,we report on the heteroepitaxial construction,band structure alignment and polarization engineering of the single-phasedκ-Ga_(2)O_(3)/GaN ferroelectric/polar heterojunction.A type-II band alignment is determined at theκ-Ga_(2)O_(3)/GaN polar hetero-interface,with a valence band offset of(1.74±0.1)eV and a conduction band offset of(0.29■0.1)eV.Besides the band edge discontinuity,charge dipoles induced by spontaneous polarization lead to the observed band bending with built-in potentials of 0.9 and 0.33 eV,respectively,at theκ-Ga_(2)O_(3)surface andκ-Ga_(2)O_(3)/GaN interface.The polarization switching properties of ferroelectricκ-Ga_(2)O_(3)are identified with a remanent polarization of approximately 2.7μC/cm^(2)via the direct hysteresis remanent polarization/voltage(P-V)loop measurement.These findings allow the rational design ofκ-Ga_(2)O_(3)ferroelectric/polar heterojunction for the application of power electronic devices,advanced memories and even ultra-low loss negative capacitance transistors.Yanting Chen Hongkai Ning Yue Kuang Xing-Xing Yu He-He Gong Xuanhu Chen Fang-Fang Ren Shulin Gu Rong Zhang Youdou Zheng Xinran Wang Jiandong Ye 2022Science China(Physics,Mechanics & Astronomy)2022,65,7:1

8Dissolved organic matter accelerates microbial degradation of 17 alpha-ethinylestradiol in the presence of iron mineral显示文摘Dissolved organic matter(DOM)and iron minerals widely existing in the natural aquatic environment can mediate the migration and transformation of organic pollutants.However,the mechanism of interaction between DOM and iron minerals in the microbial degradation of pollutants deserves further investigation.In this study,the mechanism of 17 alphaethinylestradiol(EE2)biodegradation mediated by humic acid(HA)and three kinds of iron minerals(goethite,magnetite,and pyrite)was investigated.The results found that HA and iron minerals significantly accelerated the biodegradation process of EE2,and the highest degradation efficiency of EE2(48%)was observed in the HA-mediated microbial system with pyrite under aerobic conditions.Furthermore,it had been demonstrated that hydroxyl radicals(HO·)was the main active substance responsible for the microbial degradation of EE2.HO·is primarily generated through the reaction between hydrogen peroxide secreted by microorganisms and Fe(II),with aerobic conditions being more conducive.The presence of iron minerals and HA could change the microbial communities in the EE2 biodegradation system.These findings provide new information for exploring the migration and transformation of pollutants by microorganisms in iron-rich environments.Huan He Min Shi Xiaoxia Yang Juhong Zhan Yanting Lin Ziwei Guo Zhicheng Liao Chaochao Lai Xiaomin Ren Bin Huang Xuejun Pan 2024Journal of Environmental Sciences2024,,5:0
9Asymmetric conductivity of the Kondo effect in cold atomic systems显示文摘Motivated by recent theoretical and experimental advances in quantum simulations using alkaline earth(AE)atoms,we put forward a proposal to detect the Kondo physics in a cold atomic system.It has been demonstrated that the intrinsic spin-exchange interaction in AE atoms can be significantly enhanced near a confinement-induced resonance(CIR),which facilitates the simulation of Kondo physics.Since the Kondo effect appears only for antiferromagnetic coupling,we find that the conductivity of such system exhibits an asymmetry across a resonance of spin-exchange interaction.The asymmetric conductivity can serve as the smoking gun evidence for Kondo physics in the cold atom context.When an extra magnetic field ramps up,the spin-exchange process near Fermi surface is suppressed by Zee-man energy and the conductivity becomes more and more symmetric.Our results can be verified in the current experimental setup.Yanting Cheng Xin Chen Ren Zhang 2022Frontiers of physics2022,17,1:0
10A Novel Masking Scheme for SM3 Based MAC显示文摘The Chinese hash algorithm SM3 is verified to be secure enough,but improper hardware implementation may lead to leakage.A masking scheme for SM3 algorithm is proposed to ensure the security of SM3 based Message Authentication Code(MAC).Our scheme was implemented in hardware,which utilizes hardware oriented secure conversion techniques between boolean and arithmetic masking.Security evaluation based on SAKURA-G FPGA board has been done with 2000 power traces from 2000 random plaintexts with random plaintext masks and random key masks.It has been verified that the masked SM3 hardware implementation shows no intermediate value leakage as expected.Our masked SM3 hardware can resist first-order correlation power attack(CPA) and collision correlation attack.QU Kaige WU Liji WANG An REN Yanting ZHANG Xiangmin 2015China Communications2015,12,6:0
11Characterization and implications of prokaryotic ribosome-binding sites across species显示文摘The ribosome-binding site(RBS)in the 5′untranslated region is recognized by 16S rRNA to start translation and is an essential element of the gene expression system.RBSs have been widely applied in regulating gene expression in various scenarios,including Gram-negative or Gram-positive bacteria.Here,we first rationally designed and constructed an RBS mutant library containing 66 RBSs.The strength of these RBSs in E.coli and C.glutamicum was characterized individually.The RBS strength spanned about 200 and 15 times in the two species,respectively.The strength of RBSs in C.glutamicum was generally lower than that of in E.coli.A total of 18 RBSs showed similar strength(within twofold differences)between the species in our study,and the correlation analysis of the strength of RBSs between E.coli and C.glutamicum(R^(2)=0.7483)revealed that these RBSs can be used across species.The sequence analysis revealed that the RBS region with two Ts stated was beneficial for RBS to function cross-species.The RBS characterized here can be used to precisely regulate gene expression in both hosts,and the characteristics of cross-species RBSs provide basic information for RBS rational design.Yanting Duan Xiaojuan Zhang Weiji Zhai Jinpeng Zhang Jiawei Ren Xiaomei Zhang Guoqiang Xu Jinsong Shi Zhenghong Xu 2022Systems Microbiology and Biomanufacturing2022,2,4:0

13Modification and sequential treatment of EU-1 zeolite in mild alkali and alkaline-acid conditions显示文摘EU-1 zeolites were sequentially treated with low-concentration sodium carbonate(Na_2CO_3) and hydrochloric acid(HCl) solutions.The obtained samples were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),N_2 adsorption/desorption,temperature programmed desorption of NH_3(NH_3-TPD),solid state^(27)A1 nuclear magnetic resonance(^(27)A1 NMR),and the catalytic performances of the treated samples were tested in the xylene isomerization reaction.The results showed that the external surface area and mesoporous volume of the sample sequentially treated with 0.05 mol·L^(-1) Na_2CO_3 and 0.1 mol·L^(-1) HCl solutions reached73.9 m^2·g^(-1) and 0.162 cm^3·g^(-1),respectively.The catalytic performances of EU-1 zeolites were significantly improved,that the activity of the probe reaction increased from 23.03%to 23.61%and the selectivity increased from85.09%to 87.14%compared with those of parent sample.Furthermore,it was found that only amorphous silica and alumina species was dissolved during the post-treatment process,but the framework structure and the acidic properties of EU-1 zeolite remained intact.Xiaofeng Li Xiaotao Sun Yanting Zhang Junliang Zhang Pengchao Ren Xiaozhen Liu Tao Dou 2016Chinese Journal of Chemical Engineering2016,24,12:0
