1One-step disposal of Cr (Ⅵ)-bearing wastewater by natural pyrrhotite显示文摘Cr(Ⅵ)-bearing wastewater can be treated by natural pyrrhotite which is used for reductant to reduce Cr(Ⅵ) and precipitant to precipitate Cr(Ⅲ) simultaneously. The disposal products can be divided into three parts in the beakers, namely supernatant in the upper part, the yellowish colloidal precipitates in the middle part and the pyrrhotite in the lower part. The content of total Cr=Cr(Ⅵ)+Cr(Ⅲ) in the supernatant liquid is 0.06 mg/L, which is lower than 1.5 mg/L of the discharge standard of China and near to 0.05 mg/L of the standard of potable water. This one-step disposal composing of both reduction and precipitation which is traditionally divided into two independent steps called reducing technology and precipitating technology respectively. The new method is of obvious economic advantage and favourable to decreasing surplus mud derived from adding Ca(OH)2 to precipitate Cr(Ⅲ) traditionally so as to avoid recontamination. In fact, sodium sulfite (Na2SO3) used in disposal of Cr(Ⅵ) wasLU Anhuai, CHEN Jie, SHI Junxian, LU Xiaoying, TANG Junli & GUO Min1. Departmenl of Geology, Peking University, Beijing 100871, China 2.

2Concise and efficient direct-view generation of arbitrary cylindrical vector beams by a vortex half-wave plate显示文摘A concise, efficient, and practical direct-view scheme is presented to generate arbitrary cylindrical vector(CV)beams, including CV beams, vortex beams, and cylindrical vector vortex(CVV) beams, by a vortex half-wave plate(VHP). Six kinds of first-order and other high-order CV beams, such as azimuthally polarized(AP) beams, antivortex radial polarization mode beams, and three-order AP beams, are formed by simply rotating a half-wave plate. The Stokes parameters and double-slit interference of multitype CV beams are investigated in detail.The polarization parameters, including degree of polarization, polarization azimuth, and ellipticity, are obtained,which demonstrates the efficient generation of CV beams. In addition, the double-slit interference experiment is introduced in the setup, and fringe misplacement and tilt appear for CVV beams, in which the misplacement number M is 2P+1 for P ≤ 2 and 2P-1 for P ≥ 3, where P is the polarization order number, and the fringe tilt offset is positively related to the topological charge number l of CVV beams. In addition, new types of VHPs can be formed by cascading two or more VHPs when the types of available VHPs are limited, assisting in more flexible generation of multitype CV beams. It is experimentally demonstrated that arbitrary CV beams with high quality are effectively achieved by the proposed setup, and the double-slit interference method can be utilized to determine and analyze CV beams rapidly and concisely by practical performance, which shows the potential to be implemented as a commercial device.JUNLI QI WEIHUA WANG BO SHI HUI ZHANG YANAN SHEN HAIFEI DENG WENJING PU XIN LIU HUIHUI SHAN XIAOMIN MA LIANQIANG ZHANG WEI LU MEICHENG FU XIUJIAN LI 2021Photonics Research2021,9,5:4

5Key immunity characteristics of diverse stages of brucellosis in rural population from Inner Mongolia, China显示文摘Background: Brucellosis poses a serious threat to human and animal health,particularly in developing countries such as China.The Inner Mongolia Autonomous Region is one of the most severely brucellosis-endemic provinces in China.Currently,the host immune responses functioning to control Brucella infection and development remain poorly understood.The aim of this study is to further clarify the key immunity characteristics of diverse stages of brucellosis in Inner Mongolia.Methods: We collected a total of 733 blood samples from acute(n=137),chronic(n=316),inapparent(n=35),recovery(n=99),and healthy(n=146)groups from the rural community of Inner Mongolia between 2014 and 2015.The proportions of CD4^(+),CD8^(+),Th1,Th2,and Th17 T cells in peripheral blood and the expression of TLR2 and TLR4 in lymphocytes,monocytes and granulocytes were examined using flow cytometry analysis.The differences among the five groups were compared using one-way ANOVA and the Kruskal–Wallis method,respectively.Results: Our results revealed that the proportions of CD4^(+) and CD8^(+) T cells were significantly different among the acute,chronic,recovery,and healthy control groups(P<0.05),with lower proportions of CD4^(+) T cells and a higher proportion of CD8^(+) T cells in the acute,chronic,and recovery groups.The proportion of Th1 cells in the acute,chronic,and inapparent groups was higher than that in the healthy and recovery groups;however,there was no significant difference between patients and healthy individuals(P>0.05).The proportion of Th2 lymphocytes was significantly higher in the acute and healthy groups than in the inapparent group(P<0.05).The proportion of Th17 cells in the acute group was significantly higher than that in the healthy control,chronic,and inapparent groups(P<0.05).Finally,the highest expression of TLR4 in lymphocytes,monocytes and granulocytes was observed in the recovery group,and this was followed by the acute,chronic,healthy control,and inapparent groups.There was a significant difference between the recovery group and the other groups,except for the acute group(P<0.05).Moreover,a correlation in TLR4 expression was observed in lymphocytes,monocytes and granulocytes among the five groups(r>0.5),except for the inapparent group between lymphocytes and granulocytes(r=0.34).Conclusions: Two key factors(CD8^(+)T cells and TLR4)in human immune profiles may closely correlate with the progression of brucellosis.The detailed function of TLR4 in the context of a greater number of cell types or tissues in human or animal brucellosis and in larger samples should be further explored in the future.Yongzhang Zhu Li Shi Yige Zeng Dongri Piao Yingbo Xie Juan Du Meng Gao Wei Gao Junli Tian Jun Yue Min Li XiaoKui Guo Yufeng Yao YaoXia Kang 2022Infectious Diseases of Poverty2022,11,3:1
6Anode reaction mechanisms of Na|NaCl-CaCl2|Zn liquid metal battery显示文摘Na|NaCl-CaCl_(2)|Zn liquid metal battery is regarded as a promising energy storage system for power grids.Despite intensive attempts to present a real mechanism of metal electrodes reaction, those for Na||Zn LMBs are not clear yet. Herein, the anode reactions for the multiple discharge potential plateaus were deduced by means of FactSage thermochemical software, which were subsequently validated by X-ray diffraction analysis and the modeling of phase transformation in the cooling process. A pre-treatment process was proposed for the analysis of anode product composition using the atomic absorption spectrometry method, and the anode states at working temperature(560 ℃) were obtained by the Na-CaZn ternary phase for the first time. The results indicate the discharge of Na and Ca led to the formation of Ca-Zn intermetallic compounds, whilst the extraction of Ca in Ca-Zn intermetallic compounds was responsible for the multiple discharge plateaus. Moreover, it was found that the charging product was in electrochemical double liquid metal layers, which are composed of Na and Ca with dissolved Zn respectively.Fang Zhang jingyun Jin Junli xu Zhongning Shi 2022Journal of Energy Chemistry2022,31,9:1

11Slurry-like hybrid electrolyte with high lithium-ion transference number for dendrite-free lithium metal anode显示文摘Lithium metal anode is regarded as the ultimate choice for next-generation energy storage systems,due to the lowest negative electrochemical potential and super high theoretical specific capacity.However,the growth of lithium dendrite during the cycling process is still one of the most critical bottlenecks for its application.In this work,a slurry-like hybrid electrolyte is proposed towards the application for lithium metal anode,which is composed of a liquid electrolyte part and a nanometric silane-Al2O3 particle part.The hybrid electrolyte shows high ionic conductivity(3.89×10-3 S cm-1 at 25℃)and lithium-ion transference number(0.88).Especially,the resistance of hybrid electrolyte decreases compared to that of liquid electrolyte,while the viscosity of hybrid electrolyte increases.It is demonstrated that the hybrid electrolyte can effectively suppress the growth of lithium dendrite.Stable cycling of Li/Li cells at a current density up to 1 mA cm-2 is possible.The hybrid electrolyte helps to uniform the lithium ion flux inside the battery and partly comes from the formation of a rigid and highly conductive hybrid interfacial layer on the surface of lithium metal.This work not only provides a fresh way to stabilize lithium metal anode but also sheds light on further research for electrolyte optimization and design of lithium metal battery system.Hewei Xu Ying He Zibo Zhang Junli Shi Pingying Liu Ziqi Tian Kan Luo Xiaozhe Zhang Suzhe Liang Zhaoping Liu 2020Journal of Energy Chemistry2020,29,9:1

17Dynamic response of pulsed laser-irradiated space debris显示文摘High-velocity small-sized space debris with a diameter of 1—10 cm can cause huge damage to orbiting satellites and spacecraft.In recent years,the technology of actively removing small-sized space debris by high-energy pulsed laser irradiation has attracted widespread attention from scholars around the world,who strive for giving the maximum protection to the safety of the low-earth orbit environment.This paper focuses on exploring the dynamic behavior of centimeter-sized space debris under space-based pulsed laser irradiation.For this purpose,a fluid-structure-thermal-plasma multiphysics coupling model is built for space debris,and the effect law of plasma plumes produced by space debris after laser irradiation at different time is drawn.The simulation and measurement results are compared for analysis,verifying the validity and reliability of the proposed method and the built simulation model.The findings of this study are expected to provide an important theoretical reference and guidance for the research on the application of pulsed lasers to the active removal of centimeter-sized space debris.LIANG Xiaobo FENG Tao QU Junli SHI Mingdong TANG Hailiang ZHU Chunyan 2023Optoelectronics Letters2023,19,5:0
18An iASPP-derived short peptide restores p53-mediated cell death in cancers with wild-type p53显示文摘Background:Inhibitor of apoptosis-stimulating protein of p53(iASPP)is an evolutionarily conserved p53 inhibitor.Mechanistically,iASPP can accelerate tumorigenesis by inhibiting the transactivation function of p53.Targeting the interaction between iASPP and p53 may be a potential therapy for restoring the activity of p53 in tumors.Methods:We constructed an iASPP-derived peptide,called A8,that was derived from the C-terminus of iASPP.Here,we transfected A8 into two wildtype(WT)p53 cell lines,U2OS and A549,and then determined the number of apoptotic cells.The mechanism by which A8 affected apoptosis was further examined by immunoprecipitation(IP),Dual-Luciferase reporter assays,and chromatin IP assays.Real-time polymerase chain reaction and western blots were also used to examine the expression levels of apoptosis-related factors.Results:Our data demonstrate that A8 can increase apoptosis rates in WT p53 cell lines.Functional analysis suggested that A8 restored the transcriptional function and DNA binding activities of p53 toward the Bax and PUMA gene promoters.Moreover,A8 reduced cell proliferation and inhibited tumor growth in xenograft nude mice.Conclusions:These data provide a new approach for restoring the tumor suppressor function of p53 in cancer cells that express WT p53 and therefore may serve as a novel cancer treatment strategy.Shi Qiu Wei Qi Wen Wu Qian Qiu Jiali Ma Yingjun Li Wenhui Fan Junli Li Yang Xu Hai Chen Jie Liu 2023iLABMED2023,1,2:0
19High-Porosity Foam-Based Iontronic Pressure Sensor with Superhigh Sensitivity of 9280 kPa^(-1)显示文摘Flexible pressure sensors with high sensitivity are desired in the fields of electronic skins,human-machine interfaces,and health monitoring.Employing ionic soft materials with microstructured architectures in the functional layer is an effective way that can enhance the amplitude of capacitance signal due to generated electron double layer and thus improve the sensitivity of capacitive-type pressure sensors.However,the requirement of specific apparatus and the complex fabrication process to build such microstructures lead to high cost and low productivity.Here,we report a simple strategy that uses open-cell polyurethane foams with high porosity as a continuous three-dimensional network skeleton to load with ionic liquid in a one-step soak process,serving as the ionic layer in iontronic pressure sensors.The high porosity(95.4%) of PU-IL composite foam shows a pretty low Young's modulus of 3.4 kPa and good compressibility.A superhigh maximum sensitivity of 9,280 kPa^(-1) in the pressure regime and a high pressure resolution of 0.125% are observed in this foam-based pressure sensor.The device also exhibits remarkable mechanical stability over 5,000 compression-release or bending-release cycles.Such high porosity of composite structure provides a simple,cost-effective and scalable way to fabricate super sensitive pressure sensor,which has prominent capability in applications of water wave detection,underwater vibration sensing,and mechanical fault monitoring.Qingxian Liu Yuan Liu Junli Shi Zhiguang Liu Quan Wang Chuan Fei Guo 2022Nano-Micro Letters2022,14,2:0
20Morphodynamic response of an embayed beach to different typhoon events with varying intensities显示文摘Beach erosion has occurred globally in recent decades due to frequent and severe storms.Dongsha beach,located in Zhujiajian Island,Zhejiang Province,China,is a typical embayed sandy beach.This study focused on the morphodynamic response of Dongsha beach to typhoon events,based on beach topographies and surficial sediment characteristics acquired before and after four typhoon events with varying intensities.The four typhoons had different effects on the topography and sediment characteristics of Dongsha beach.Typhoons Ampil and Danas caused the largest(-51.72 m3/m)and the smallest erosion(-8.01 m3/m),respectively.Remarkable alongshore patterns of beach profile volumetric changes were found after the four typhoon events,with more erosion in the southern and central parts of the beach and few changes in the northern part.Grain size coarsening and poor sorting were the main sediment patterns on the beach influenced by different typhoons.Typhoons that occurred in the same year after another typhoon enhanced the effect of the previous typhoon on sediment coarsening and sorting variability,but this cumulative effect was not found between typhoons that occurred during different years.A comparison of the collected data revealed that the topographic state of the beach before the typhoon,typhoon characteristics,and tidal conditions were possible reasons for the difference in the responses of Dongsha beach to typhoon events.More severe beach erosion was caused by typhoons with higher intensity levels and longer durations,and high tide levels during typhoons can determine the upper limit of the beach profile erosion site.Taken together,these results can be used to improve beach management for storm prevention.Lianqiang Shi Junli Guo Shenliang Chen Yang Chang Daheng Zhang Zhaohui Gong 2023Acta Oceanologica Sinica2023,42,7:0
