| 1 | Flower-, wire-, and sheet-like MnO_2-deposited diatomites:Highly efficient absorbents for the removal of Cr(Ⅵ)显示文摘Flower-, wire-, and sheet-like MnO2-deposited diatomites have been prepared using a hydrothermal method with Mn(Ac)2, KMnO4and/or MnSO4 as Mn source and diatomite as support. Physical properties of the materials were characterized by means of numerous analytical techniques, and their behaviors in the adsorption of chromium(VI) were evaluated.It is shown that the MnO2-deposited diatomite samples with different morphologies possessed high surface areas and abundant surface hydroxyl groups(especially the wire-like MnO2/diatomite sample). The wire-like MnO2/diatomite sample showed the best performance in the removal of Cr(VI), giving the maximum Cr(VI) adsorption capacity of 101 mg/g. | Yucheng Du Liping Wang Jinshu Wang Guangwei Zheng Junshu Wu Hongxing Dai | 2015 | Journal of Environmental Sciences2015，27，3： | 17 |
| 2 | Full-space Cloud of Random Points with a Scrambling Metasurface显示文摘With the rapid progress in computer science,including artificial intelligence,big data and cloud computing,full-space spot generation can be pivotal to many practical applications,such as facial recognition,motion detection,augmented reality,etc.These opportunities may be achieved by using diffractive optical elements(DOEs)or light detection and ranging(LIDAR).However,DOEs suffer from intrinsic limitations,such as demanding depth-controlled fabrication techniques,large thicknesses(more than the wavelength),Lambertian operation only in half space,etc.LIDAR nevertheless relies on complex and bulky scanning systems,which hinders the miniaturization of the spot generator.Here,inspired by a Lambertian scatterer,we report a Hermitian-conjugate metasurface scrambling the incident light to a cloud of random points in full space with compressed information density,functioning in both transmission and reflection spaces.Over 4044 random spots are experimentally observed in the entire space,covering angles at nearly 90°.Our scrambling metasurface is made of amorphous silicon with a uniform subwavelength height,a nearly continuous phase coverage,a lightweight,flexible design,and low-heat dissipation.Thus,it may be mass produced by and integrated into existing semiconductor foundry designs.Our work opens important directions for emerging 3D recognition sensors,such as motion sensing,facial recognition,and other applications. | Zile Li Qi Dai Muhammad Q.Mehmood Guangwei Hu Boris Luk’yanchuk Jin Tao Chenglong Hao Inki Kim Heonyeong Jeong Guoxing Zheng Shaohua Yu Andrea Alù Junsuk Rho Cheng-Wei Qiu | 2018 | Light(Science & Applications)2018，7，1： | 6 |
| 3 | Status of the IHEP 1.3 GHz superconducting RF program显示文摘The 1.3 GHz superconducting radio-frequency (SRF) technology is one of the key technologies for the ILC and future XFEL and ERL projects in China. With the aim to develop 1.3 GHz SRF technology, IHEP has started a program to build an SRF Accelerating Unit. This unit contains a 9-cell 1.3 GHz superconducting cavity, a short cryomodule, a high power input coupler, a tuner and a low level RF system. This program also includes the SRF laboratory upgrade, which will permit the unit to be built and tested at IHEP. The unit will be used for the 1.3 GHz SRF system integration study, high power horizontal test and possible beam test in the future. In this paper, we report the recent R&D status of this program. The first large grain low-loss shape 9-cell superconducting RF cavity made by IHEP reached 20 MV/m in the first vertical test in July, 2010. The prototype tuner and low level RF (LLRF) system are under test. The high power input coupler and cryomodule are under fabrication. Several key SRF facilities for 9-cell cavity surface treatment and pre-tuning were successfully commissioned and are in operation. | GAO Jie ZHAI JiYuan PAN WeiMing LI ShaoPeng SUN Yi DAI JianPing CHI YunLong LI ZhongQuan ZHAO TongXian HUANG TongMing MA Qiang GE Rui LI ChunHua GUO HaiSheng WANG GuangWei QIU Feng LIN HaiYing HOU Mi WANG QunYao | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，S2： | 1 |

| 5 | R&D of BEPCII 500 MHz superconducting cavity显示文摘Beijing Electron-Positron Collider Upgrade (BEPCII) adopts two 500 MHz superconducting cavities (SCCs) in each ring for higher accelerated gradient, higher Q and lower impedance (Wang et al. The proceedings of SRF'07). There's no spare cavity due to the limited time and funding during BEPCII construction. If any serious trouble happened on either one of the two cavities and could not be recovered in a short time, the operation of BEPCII facility will be affected. Therefore, since 2009 three spare cavities have been fabricated in China to ensure reliable operation, and two of them have been successfully vertically tested in January and July 2011. This paper will briefly present the manufacture, post-process and vertical test performance of the 500 MHz spare cavities. | LIU YaPing WANG GuangWei PAN WeiMin LI JiZhen LIU DeGui SUN Yi LI ZhongQuan DAI JianPing LI ShaoPeng HE Kun WANG GuoPing ZHAO GuangYuan MA Qiang LIN HaiYing SHA Peng WANG QunYao QIU Feng MENG FanBo LI Han | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，S2： | 0 |
| 6 | Development and validation of a risk-prediction model for immune-related adverse events in patients with non-small-cell lung cancer receiving PD-1/PD-L1 inhibitors显示文摘Lung cancer remains the leading cause of cancer deaths worldwide and is the most common cancer in males.Immune-checkpoint inhibitors(ICIs)that target programmed cell death protein-1(PD-1)or programmed cell death-ligand 1(PD-L1)have achieved impressive efficacy in the treatment of non-small-cell lung cancer(NSCLC)(Pardoll,2012;Champiat et al.,2016;Gao et al.,2022).Although ICIs are usually well tolerated,they are often accompanied by immune-related adverse events(irAEs)(Doroshow et al.,2019).Non-specific activation of the immune system produces off-target immune and inflammatory responses that can affect virtually any organ or system(O'Kane et al.,2017;Puzanov et al.,2017). | Qing QIU Chenghao WU Wenxiao TANG Longfei JI Guangwei DAI Yuzhen GAO Enguo CHEN Hanliang JIANG Xinyou XIE Jun ZHANG | 2023 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2023，24，10： | 0 |
