| 1 | Effects of insoluble Zn,Cd,and EDTA on the growth,activities of antioxidant enzymes and uptake of Zn and Cd in Vetiveria zizanioides显示文摘A root-bag experiment was conducted to study the effects of insoluble Zn,Cd,and ethylenediaminetetraacetic acid(EDTA) on the plant growth,activities of antioxidant enzymes,proline,glutathione(GSH),water-soluble proteins and malondialdehyde(MDA) of Vetiveria zizanioides.The V.zizanioides uptake capacity of Zn and Cd also determined.The results showed that plant growth of V.zizanioides was inhibited by Zn and Cd.The shoot dry weight(SDW) and root dry weight(RDW) decrease by 14.2%,14.1%,17.0% and 17.3%,32.5%,35.7%,respectively,compared to the control without EDTA addition.After adding EDTA,shoot and root dry weight decreased over 10% and 15%,respectively.The toxicity from insoluble Zn and Cd in soil on SDW and RDW of V.zizanioides was in order:Zn+Cd > Cd > Zn.The activities of superoxide dismutase(SOD),peroxidase(POD) and catalase(CAT),and contents of MDA and proline increased significantly,while the contents of GSH and water-soluble proteins decreased markedly with increasing Zn and Cd toxicity.With EDTA,shoot and root Zn concentrations increased in the Zn treatment by 7.3% and 37.4%,and Cd concentrations in the combined Zn and Cd treatment increased by 18.6% and 391.9% compared to the treatment without EDTA.However,Zn and Cd concentrations in shoot and roots decreased in the Cd treatment compared to the plants grown in absence of EDTA,with exception of root Cd concentration in the presence of EDTA. | XU Weihong LI Wenyi HE Jianping Balwant Singh XIONG Zhiting | 2009 | Journal of Environmental Sciences2009，21，2： | 16 |
| 2 | Highly conductive dodecaborate/MXene composites for high performance supercapacitors显示文摘With the increasingly prominent energy and environmental issues,the supercapacitors,as a highly efficient and clean energy conversion and storage devices,meet the requirements well.However,it is still a challenge to enhance the capacitance and energy density of supercapacitors.A novel and highly conductive dodecaborate/MXene composites have been designed for high performance supercapacitors.The surface charge property of MXene was modified by a simple ultrasonic treatment with ammonium ion,and the dodecaborate ion can be inserted into the inner surface of MXene by electrostatic adsorption.Due to the unique icosahedral cage conjugate structure formed by the B-B bond and the highly delocalized three-dimensionalπbond structure of the electrons,the negative charge is delocalied on the whole dodecaborate ion,which reduces the ability to bind to cations.Therefore,the cations can move easily,and the dodecaborate can act as a“lubricant”for ion diffusion between the MXene layers,which significantly improves the ion transfer rate of supercapacitors.The dodecaborate/MXene composites can achieve an extremely high specific capacitance of 366 F.g^-1 at a scan rate of 2 mV.s^-1,which is more than eight times higher than that of MXene(43 F1-)at the same scan rate.Our finding provides a novel route on the fabrication of the high performance supercapacitors. | Zhenxing Li Chang Ma Yangyang Wen Zhiting Wei Xiaofei Xing Junmei Chu Chengcheng Yu Kaili Wang Zhao-Kui Wang | 2020 | Nano Research2020，13，1： | 7 |

| 5 | Design and Optimization of a Single Stage Centrifugal Compressor for a Solar Dish-Brayton System显示文摘According to the requirements of a solar dish-Brayton system,a centrifugal compressor stage with a minimum total pressure ratio of 5,an adiabatic efficiency above 75% and a surge margin more than 12% needs to be designed.A single stage,which consists of impeller,radial vaned diffuser,90° crossover and two rows of axial stators,was chosen to satisfy this system.To achieve the stage performance,an impeller with a 6:1 total pressure ratio and an adiabatic efficiency of 90% was designed and its preliminary geometry came from an in-house one-dimensional program.Radial vaned diffuser was applied downstream of the impeller.Two rows of axial stators after 90° crossover were added to guide the flow into axial direction.Since jet-wake flow,shockwave and boundary layer separation coexisted in the impeller-diffuser region,optimization on the radius ratio of radial diffuser vane inlet to impeller exit,diffuser vane inlet blade angle and number of diffuser vanes was carried out at design point.Finally,an optimized centrifugal compressor stage fulfilled the high expectations and presented proper performance.Numerical simulation showed that at design point the stage adiabatic efficiency was 79.93% and the total pressure ratio was 5.6.The surge margin was 15%.The performance map including 80%,90% and 100% design speed was also presented. | Yongsheng Wang Kai Wang Zhiting Tong Feng Lin Chaoqun Nie Abraham Engeda | 2013 | Journal of Thermal Science2013，22，5： | 5 |
| 6 | Synergistic cerium doping and MXene coupling in layered double hydroxides as efficient electrocatalysts for oxygen evolution显示文摘Oxygen evolution reaction(OER) is a bottle-neck process in many sustainable energy conversion systems due to its sluggish kinetics.The development of cost-effective yet efficient electrocatalysts towards OER is highly desirable but still a great challenge at current stage.Herein,a new type of hybrid nanostructure,consisting of two-dimensional(2D) Cerium-doped NiFe-layered double hydroxide nanoflakes directly grown on the 2D Ti3C2Tx MXene surface(denoted as NiFeCe-LDH/MXene),is designed using a facile insitu coprecipitation method.The resultant NiFeCe-LDH/MXene hybrid presents a hierarchical nanoporous structure,high electrical conductivity and strong interfacial junction because of the synergistic effect of Ce doping and MXene coupling.As a result,the hybrid catalyst exhibits an excellent catalytic activity for OER,delivering a low onset overpotential of 197 mV and an overpotential of 260 mV at a current density of 10 mA·cm-2 in the alkaline medium,much lower than its pure LDH counterparts and IrO2 catalyst.Besides,the hybrid catalyst also displays a fast reaction kinetics and a remarkable stable durability.Further theoretic studies using density function theory(DFT) methods reveal that Ce doping could effectively narrow the bandgap of NiFe-LDH and reduce the overpotential in OER process.This work may shed light on the exploration of advanced electrocatalysts for renewable energy conversion and storage systems. | Yangyang Wen Zhiting Wei Jiahao Liu Rui Li Ping Wang Bin Zhou Xiang Zhang Jiang Li Zhenxing Li | 2021 | Journal of Energy Chemistry2021，30，1： | 4 |

| 10 | A review on SRAM-based computing in-memory:Circuits,functions,and applications显示文摘Artificial intelligence(AI)processes data-centric applications with minimal effort.However,it poses new challenges to system design in terms of computational speed and energy efficiency.The traditional von Neumann architecture cannot meet the requirements of heavily datacentric applications due to the separation of computation and storage.The emergence of computing inmemory(CIM)is significant in circumventing the von Neumann bottleneck.A commercialized memory architecture,static random-access memory(SRAM),is fast and robust,consumes less power,and is compatible with state-of-the-art technology.This study investigates the research progress of SRAM-based CIM technology in three levels:circuit,function,and application.It also outlines the problems,challenges,and prospects of SRAM-based CIM macros. | Zhiting Lin Zhongzhen Tong Jin Zhang Fangming Wang Tian Xu Yue Zhao Xiulong Wu Chunyu Peng Wenjuan Lu Qiang Zhao Junning Chen | 2022 | Journal of Semiconductors2022，43，3： | 2 |
| 11 | An Enhanced IRC Algorithm for LTE Downlink Receiver in Multi-cell Environment显示文摘This paper proposes an enhanced Interference rejection combining(IRC) algorithm for Long term evolution(LTE) downlink receiver in multi-cell communication systems. In this algorithm, a proper Multiple input multiple output(MIMO) receive method is adopted according to Generalized likelihood ratio test(GLRT) intercell interference detection. Iteration between channel estimation and data detection is carried out to improve the performance of IRC algorithm. Simulation results show that this proposed algorithm can effectively detect intercell interference and improve Block error rate(BLER)performance and channel estimation Mean squared error(MSE) compared to non-iterative IRC algorithm, making it suitable for LTE downlink receiver in multi-cell cellular systems. | YAN Zhiting HE Guanghui MA Jun | 2014 | Chinese Journal of Electronics2014，23，2： | 2 |

| 18 | Upstream CRP-binding site is not essential for CRP-cAMP-mediated inhibition on the nifU promoter显示文摘When the NifA-mediated activation of Kleb-siella pneumontae nifU promoter is recreated in Escherichia coli, it has been observed that CRP-cAMP has an inhibitory effect on the nifU promoter. Sequence analysis indicates that there is a strong CRP-binding site located upstream of the nifU promoter, overlapping completely with a previously identified Nif A-binding site. In vitro gel retardation analysis indicates that this putative CRP-binding site has similar affinity for CRP, when compared with that at the lac promoter, suggesting that CRP could effectively compete with NifA for such a binding site under physiological conditions. When this putative CRP-binding site on nifU was mutated, in vitro gel retardation analysis indicates that CRP can no longer bind to the mutant promoter. However, when constitutively expressed NifA is used as the activator, CRP-cAMP-mediated inhibitory effect on this mutant nifU promoter has no significant difference when compared with that obtained from its wild-type promoter. | LI Zhiting ZHANG Weijia WANG Yiping | 2002 | Chinese Science Bulletin2002，47，21： | 1 |
