| 1 | Polarization-independent all-silicon dielectric metasurfaces in the terahertz regime显示文摘Dielectric metasurfaces have achieved great success in realizing high-efficiency wavefront control in the optical and infrared ranges. Here, we experimentally demonstrate several efficient, polarization-independent, all-silicon dielectric metasurfaces in the terahertz regime. The metasurfaces are composed of cylindrical silicon pillars on a silicon substrate, which can be easily fabricated using etching technology for semiconductors. By locally tailoring the diameter of the pillars, full control over abrupt phase changes can be achieved. To show the controlling ability of the metasurfaces, an anomalous deflector, three Bessel beam generators, and three vortex beam generators are fabricated and characterized. We also show that the proposed metasurfaces can be easily combined to form composite devices with extended functionalities. The proposed controlling method has promising applications in developing low-loss, ultra-compact spatial terahertz modulation devices. | HUIFANG ZHANG XUEQIAN ZHANG QUAN XU QIU WANG YUEHONG XU MINGGUI WEI YANFENG LI JIANQIANG GU ZHEN TIAN CHUNMEI OUYANG XIXIANG ZHANG CONG HU JIAGUANG HAN WEILI ZHANG | 2018 | Photonics Research2018，9，1： | 4 |
| 2 | Pt-Sn clusters anchored at Al_(penta)^(3+) sites as a sinter-resistant and regenerable catalyst for propane dehydrogenation显示文摘Pt-based catalysts are widely used in propane dehydrogenation reaction for the production of propylene.Suppressing irreversible deactivation caused by the sintering of Pt particles under harsh conditions and regeneration process is a significant challenge in this catalyst.Herein,a series of highly ordered mesoporous Al_(2)O_(3) supports with different levels of Al3+penta sites,are fabricated and used as the support to disperse Pt-Sn_(2) clusters.Characterizations of Pt-Sn_(2)/meso-Al_(2)O_(3) with XRD,NMR,CO-IR,STEM,TG,and Raman techniques along with propane dehydrogenation-regeneration cycles test reveal the structure-stability-re generability relationship.The coordinatively unsaturated pentacoordinate Al_(Al3+penta)^(3+)can strongly anchor Pt atoms via a formation of Al-O-Pt bond,and thus stabilize the Pt-based particles at the surface of Al_(2)O_(3).The stability and regenerability of Pt-Sn2/meso-Al_(2)O_(3) are strongly dependent on the content of Al3+penta sites in the Al_(2)O_(3) structure,and a high level of Al3+penta sites can effectively prevent the agglomeration of Pt-Sn2 clusters into large Pt nanoparticles in the consecutive dehydrogenation-regeneration cycles.The Pt-Sn2/meso-Al_(2)O_(3)-600 with the highest level of Al_(penta)^(3+) (50.8%)delivers the best performance in propane dehydrogenation,which exhibits propane conversion of 40%and propylene selectivity above 98%at 570℃ with 10 vol%C_(3)H_(8) and 10 vol% H_(2) feed.A slow deactivation in this catalyst is ascribed to the formation of coke,and the catalytic performance can be fully restored in the consecutive dehydrogenation-regeneration cycles via a simple calcination treatment. | Xinyue Zhu Tinghai Wang Zhikang Xu Yuanyuan Yue Minggui Lin Haibo Zhu | 2022 | Journal of Energy Chemistry2022，31，2： | 2 |
| 3 | Bimetallic PtSn nanoparticles confined in hierarchical ZSM-5 for propane dehydrogenation显示文摘A series of PtSn/hierarchical ZSM-5 catalysts were developed for propane dehydrogenation,in which the PtSn bimetallic particles are confined in the mesopores of hierarchical ZSM-5 zeolite.The synthesis of PtSn/hierarchical ZSM-5 catalysts was achieved via the loading of Pt and Sn species onto the hierarchical ZSM-5 catalysts that are obtained through a desilication of conventional ZSM-5.The PtSn/hierarchical ZSM-5 catalysts were fully characterized by XRD,N_(2) adsorption,STEM,XPS,and CO-IR techniques,which reveals that highly dispersed PtSn bimetallic nanoparticles are enclosed into mesopores of hierarchical ZSM-5.The catalytic performance of PtSn/hierarchical ZSM-5 is greatly affected by the concentrations of alkali solution in the desilication process and Sn/Pt ratios in PtSn bimetallic particles.The PtSn1.00/ZSM-5(0.8)catalyst shows the highest efficiency in propane dehydrogenation,which gives an initial conversion of 46%and selectivity of 98%at 570℃.The high efficiency in these PtSn/hierarchical ZSM-5 catalysts for propane dehydrogenation is mainly ascribed to the confinement of PtSn particles in the mesopores of hierarchical ZSM-5 zeolite. | Tianlei Wang Zhikang Xu Yuanyuan Yue Tinghai Wang Minggui Lin Haibo Zhu | 2022 | Chinese Journal of Chemical Engineering2022，35，1： | 2 |

| 7 | Expert Consensus on Diagnosis and Treatment of End-Stage Liver Disease Complicated with Infections显示文摘End-stage liver disease(ESLD)is a life-threatening clinical syndrome that markedly increases mortality in patients with infections.In patients with ESLD,infections can induce or aggravate the occurrence of liver decompensation.Consequently,infections are among the most common complications of disease progression.There is a lack of working procedure for early diagnosis and appropriate management for patients with ESLD complicated by infections as well as local and international guidelines or consensus.This consensus assembled up-to-date knowledge and experience across Chinese colleagues,providing data on principles as well as working procedures for the diagnosis and treatment of patients with ESLD complicated by infections. | Qin Ning Tao Chen Guiqiang Wang Dong Xu Yanyan Yu Qing Mao Taisheng Li Lanjuan Li Jun Li Xiaoju Lu Jiabin Li Zhiwei Li Wenhong Zhang Yonghong Xiao Qinghua Meng Yuqiang Mi Jia Shang Yunsong Yu Yingren Zhao Caiyan Zhao Hong Zhao Jianrong Huang Jie Peng Hong Tang Xiaoping Tang Jinhua Hu Bijie Hu Wei Guo Bo Zheng Baiyi Chen Yuexin Zhang Jia Wei Jifang Sheng Zhi Chen Minggui Wang Qing Xie Yuming Wang Fu-Sheng Wang Jinlin Hou Zhongping Duan Lai Wei Jidong Jia Chinese Society of Infectious Disease of Chinese Medical Association | 2022 | Infectious Diseases & Immunity2022，2，3： | 0 |
| 8 | Mo doping provokes two electron reaction in MnO_(2)with ultrahigh capacity for aqueous zinc ion batteries显示文摘Rechargeable aqueous zinc ion batteries(AZIBs)based on manganese dioxide(MnO_(2))have received much attention for large-scale energy storage applications,however,their energy density is mainly limited by the one-electron reaction of Mn4+/Mn3+redox.Herein,Mo dopedδ-MnO_(2)(Mo-MnO_(2))is prepared and used as a high-performance cathode for AZIBs,which delivers an⇌⇌ultrahigh specific capacity of 652 mAh·g^(−1)at 0.2 A·g^(−1)based on the two-step two-electron redox reaction of Mn^(4+)Mn^(3+)Mn^(2+).Ex-situ structural analysis and density functional theory calculation reveal that the Mo^(5+)dopant plays an important role in enhancing the electronic conductivity of Mo-MnO_(2)and promoting Jahn–Teller distortion of octahedral[MnO_(6)]in ZnMn_(2)O_(4),which facilitates the second step redox reaction of Mn^(3+)/Mn_(2+).This work provides a novel cathode materials design with multi-electron redox chemistry to achieve high energy density in AZIBs. | Xiaoyu Xia Yajun Zhao Yi Zhao Minggui Xu Wen Liu Xiaoming Sun | 2023 | Nano Research2023，16，2： | 0 |
| 9 | Asymmetric double-layer composite electrolyte with enhanced ionic conductivity and interface stability for all-solid-state lithium metal batteries显示文摘All-solid-state Li metal battery has been regarded as a promising battery technology due to its high energy density based on the high capacity of lithium metal anode and high safety based on the all solid state electrolyte without inflammable solvent.However,challenges still exist mainly in the poor contact and unstable interface between electrolyte and electrodes.Herein,we demonstrate an asymmetric design of the composite polymer electrolyte with two different layers to overcome the interface issues at both the cathode and the anode side simultaneously.At the cathode side,the polypropylene carbonate layer has enough viscosity and flexibility to reduce the inter-facial resistance,while at the Li anode side,the polyethylene oxide layer modified with hexagonal boron nitride has high mechanical strength to suppress the Li dendrite growth.Owing to the synergetic effect between different components,the asprepared double layer composite polymer electrolyte demonstrates a large electrochemical window of5.17 V,a high ionic conductivity of 6.1×10~(-4) S/cm,and a transfe rence number of 0.56,featuring excellent ion transport kinetics and good chemical stability.All-solid-state Li metal battery assembled with LiFePO_4 cathode and Li anode delivers a high capacity of 150.9 mAh/g at 25℃ and 0.1 C-rate,showing great potential for practical applications. | Binglu Zhao Luxiang Ma Kai Wu Mengxiong Cao Minggui Xu Xinxiang Zhang Wen Liu Jitao Chen | 2021 | Chinese Chemical Letters2021，32，1： | 0 |
| 10 | Microwave-assisted exploration of the electron configuration-dependent electrocatalytic urea oxidation activity of 2D porous NiCo_(2)O_(4)spinel显示文摘Urea holds promise as an alternative water-oxidation substrate in electrolytic cells.High-valence nickelbased spinel,especially after heteroatom doping,excels in urea oxidation reactions(UOR).However,traditional spinel synthesis methods with prolonged high-temperature reactions lack kinetic precision,hindering the balance between controlled doping and highly active two-dimensional(2D)porous structures design.This significantly impedes the identification of electron configuration-dependent active sites in doped 2D nickel-based spinels.Herein,we present a microwave shock method for the preparation of 2D porous NiCo_(2)O_(4)spinel.Utilizing the transient on-off property of microwave pulses for precise heteroatom doping and 2D porous structural design,non-metal doping(boron,phosphorus,and sulfur)with distinct extranuclear electron disparities serves as straightforward examples for investigation.Precise tuning of lattice parameter reveals the impact of covalent bond strength on NiCo_(2)O_(4)structural stability.The introduced defect levels induce unpaired d-electrons in transition metals,enhancing the adsorption of electron-donating amino groups in urea molecules.Simultaneously,Bode plots confirm the impact mechanism of rapid electron migration caused by reduced band gaps on UOR activity.The prepared phosphorus-doped 2D porous NiCo_(2)O_(4),with optimal electron configuration control,outperforms most reported spinels.This controlled modification strategy advances understanding theoretical structure-activity mechanisms of high-performance 2D spinels in UOR. | Jun Wan Zhiao Wu Guangyu Fang Jinglin Xian Jiao Dai Jiayue Guo Qingxiang Li Yongfei You Kaisi Liu Huimin Yu Weilin Xu Huiyu Jiang Minggui Xia Huanyu Jin | 2024 | Journal of Energy Chemistry2024，91，4： | 0 |
