1Research on single event transient pulse quenching effect in 90 nm CMOS technology显示文摘Since single event transient pulse quenching can reduce the SET(single event transient) pulsewidths effectively,the charge collected by passive device should be maximized in order to minimize the propagated SET.From the perspective of the layout and circuit design,the SET pulsewidths can be greatly inhibited by minimizing the layout spacing and signal propagation delay,which sheds new light on the radiation-hardened ICs(integrated circuits) design.Studies show that the SET pulsewidths of propagation are not in direct proportion to the LET(linear energy transfer) of incident particles,thus the defining of the LET threshold should be noted when SET/SEU(single event upset) occurs for the radiation-hardened design.The capability of anti-radiation meets the demand when LET is high but some soft errors may occur when LET is low.Therefore,radiation experiments should be focused on evaluating the LET that demonstrates the worst response to the circuit.QIN JunRui CHEN ShuMing LIU BiWei CHEN JianJun LIANG Bin LIU Zheng 2011Science China(Technological Sciences)2011,54,11:14
2Characteristics of the lunar samples returned by the Chang'E-5 mission显示文摘Forty-five years after the Apollo and Luna missions returned lunar samples,China's Chang’E-5(CE-5)mission collected new samples from the mid-latitude region in the northeastern Oceanus Procellarum of the Moon.Our study shows that 95%of CE-5 lunar soil sizes are found to be within the range of 1.40-9.35μm,while 95%of the soils by mass are within the size range of 4.84-432.27μm.The bulk density,true density and specific surface area of CE-5 soils are 1.2387 g/cm^(3),3.1952 g/cm^(3) and 0.56 m^(2)/g,respectively.Fragments from the CE-5 regolith are classified into igneous clasts(mostly basalt),agglutinate and glass.A few breccias were also found.The minerals and compositions of CE-5 soils are consistent with mare basalts and can be classified as low-Ti/low-Al/low-K type with lower rare-earth-element contents than materials rich in potassium,rare earth element and phosphorus.CE-5 soils have high FeO and low Mg index,which could represent a new class of basalt.Chunlai Li Hao Hu Meng-Fei Yang Zhao-Yu Pei Qin Zhou Xin Ren Bin Liu Dawei Liu Xingguo Zeng Guangliang Zhang Hongbo Zhang Jianjun Liu Qiong Wang Xiangjin Deng Caijin Xiao Yonggang Yao Dingshuai Xue Wei Zuo Yan Su Weibin Wen Ziyuan Ouyang 2022National Science Review2022,9,2:12
3The effect of P^+ deep well doping on SET pulse propagation显示文摘The change of P+ deep well doping will affect the charge collection of the active and passive devices in nano-technology,thus affecting the propagated single event transient(SET) pulsewidths in circuits.The propagated SET pulsewidths can be quenched by reducing the doping of P+ deep well in the appropriate range.The study shows that the doping of P+ deep well mainly affects the bipolar amplification component of SET current,and that changing the P+ deep well doping has little effect on NMOS but great effect on PMOS.QIN JunRui CHEN ShuMing LIU BiWei LIU FanYu CHEN JianJun 2012Science China(Technological Sciences)2012,55,3:7
4Intercropping of Sonchus asper and Vicia faba affects plant cadmium accumulation and root responses显示文摘The cadmium(Cd)pollution of farmland soil is serious in the world.The present study investigated the effects of intercropping Vicia faba and the hyperaccumulator Sonchus asper on the Cd accumulation and root responses(morphology and secreted organic acids)of plants grown on soil from a mining area in Yunnan Province,China,under different Cd stress levels(0,50,100,and 200 mg kg-1).Intercropping increased the biomass of both S.asper and V.faba,as well as the Cd accumulation and Cd transfer coefficient from roots to shoots of S.asper,but decreased those of V.faba in the 200 mg kg-1Cd treatment.The Cd concentrations in roots,shoots,and grains from intercropped V.faba plants were positively correlated(P<0.05)with the N,N-diethyl phenylacetamide-extractable Cd content in soil.In the 50 mg kg-1Cd treatment,intercropping decreased citric and malic acids in root secretions of S.asper.Intercropped V.faba secreted more citric,oxalic,acetic,and malic acid compared with S.asper.Intercropping also increased root length and root surface area of both S.asper and V.faba.At 50 mg kg-1Cd,root length for S.asper was higher than that at 0 mg kg-1Cd,whereas V.faba roots had significantly decreased length and mean diameter.Intercropping of S.asper and V.faba is suggested as an in situ phytoremediation strategy of Cd-contaminated soils and may improve the food quality of V.faba.Yanqun ZU Li QIN Fangdong ZHAN Jiong WU Yuan LI Jianjun CHEN Jixiu WANG Wenyou HU 2020Pedosphere2020,30,4:6
5A novel approach to melt purification of magnesium alloys显示文摘A novel low-cost method for melt purification of magnesium alloys,the melt self-purifying technology(MSPT),has been developed successfully based on a low temperature melt treatment(LTMT)without adding any fluxes.The iron solubility in the molten liquid of magnesium and its alloys,and the settlement velocity of iron particles were calculated.It is shown that the low temperature melt treatment is an effective method to decrease the impurity Fe content in magnesium and its alloys.Without any additions,the Fe content in the AZ31 alloy was reduced to 15 ppm from the initial 65 ppm,and the Fe content in the AZ61 melt was decreased to 20 ppm from the initial 150 ppm after the low temperature melt treatment.The results also showed that the Fe content in AM60 and AM50 dropped to 15 and 18 ppm,respectively,from the initial 150 ppm after the low temperature melt treatment.For ZK 60,the Fe content in the melt down to less than 5 ppm was achieved.After the low temperature melt treatment,the Si content in the above alloys was also decreased obviously.Fusheng Pan Xianhua Chen Tao Yan Tingting Liu Jianjun Mao Wei Luo Qin Wang Jian Peng Aitao Tang Bin Jiang 2016Journal of Magnesium and Alloys2016,4,1:5
6An Outbreak of Multidrug-Resistant Tuberculosis in a Secondary School --Hubei Province, 2019显示文摘What is already known about this topic?Multidrug-resistant tuberculosis(MDR-TB)is a type of tuberculosis with resistance to common treatments such as isoniazid and rifampicin.MDR-TB is a major global health challenge and needs to be controlled tightly through prevention measures,early diagnosis,and full treatment and management.What is added by this report?This outbreak was the first MDR-TB related public health emergency in Hubei Province.In total,five MDR-TB cases and nine clinically diagnosed cases were identified within one class in a secondary school.Students and teachers from other classes were monitored,but no other cases were found.What are the implications for public health practice?The implementation of TB prevention and control measures in schools is important to increase knowledge on TB and to raise awareness on protecting personal wellbeing.The Automatic Early Warning Information System alerted the local health department and allowed for a timely response to prevent further disease spread.Mengxian Zhang Tang Wang Shuangyi Hou Jianjun Ye Liping Zhou Zhong Zhang Zhiqiang Deng Qin Da Guoming Li Shiyue Li 2019China CDC weekly2019,1,5:5
7Oxygen‑Deficient β‑MnO_(2)@Graphene Oxide Cathode for High‑Rate and Long‑Life Aqueous Zinc Ion Batteries显示文摘Recent years have witnessed a booming interest in grid-scale electrochemical energy storage,where much attention has been paid to the aqueous zinc ion batteries(AZIBs).Among various cathode materials for AZIBs,manganese oxides have risen to prominence due to their high energy density and low cost.However,sluggish reaction kinetics and poor cycling stability dictate against their practical application.Herein,we demonstrate the combined use of defect engineering and interfacial optimization that can simultaneously promote rate capability and cycling stability of MnO_(2) cathodes.β-MnO_(2) with abundant oxygen vacancies(VO)and graphene oxide(GO)wrapping is synthesized,in which VO in the bulk accelerate the charge/discharge kinetics while GO on the surfaces inhibits the Mn dissolution.This electrode shows a sustained reversible capacity of~129.6 mAh g^(−1) even after 2000 cycles at a current rate of 4C,outperforming the state-of-the-art MnO_(2)-based cathodes.The superior performance can be rationalized by the direct interaction between surface VO and the GO coating layer,as well as the regulation of structural evolution ofβ-MnO_(2) during cycling.The combinatorial design scheme in this work offers a practical pathway for obtaining high-rate and long-life cathodes for AZIBs.Shouxiang Ding Mingzheng Zhang Runzhi Qin Jianjun Fang Hengyu Ren Haocong Yi Lele Liu Wenguang Zhao Yang Li Lu Yao Shunning Li Qinghe Zhao Feng Pan 2021Nano-Micro Letters2021,13,11:3
8Sound propagation from the shelfbreak to deep water显示文摘Motivated by a phenomenon in an experiment conducted in the Northwestern Pacific indicating that the energy of the received signal around the sound channel axis is much greater than that at shallower depths,we study sound propagation from the transitional area(shelfbreak)to deep water.Numerical simulations with different source depths are first performed,from which we reach the following conclusions.When the source is located near the sea surface,sound will be strongly attenuated by bottom losses in a range-independent oceanic environment,whereas it can propagate to a very long range because of the continental slope.When the source is mounted on the bottom in shallow water,acoustic energy will be trapped near the sound channel axis,and it converges more evidently than the case where the source is located near the sea surface.Then,numerical simulations with different source ranges are performed.By comparing the relative energy level in the vertical direction between the numerical simulations and the experimental data,the range of the air-gun source can be approximated.QIN JiXing ZHANG RenHe LUO WenYu PENG ZhaoHui LIU JianJun WANG DeJun 2014Science China(Physics,Mechanics & Astronomy)2014,57,6:3

103-D TCAD simulation study of the single event effect on 25 nm raised source-drain FinFET显示文摘Using Technology Computer-Aided Design(TCAD) 3-D simulation,the single event effect(SEE) of 25 nm raised source-drain FinFET is studied.Based on the calibrated 3-D models by process simulation,it is found that the amount of charge collected increases linearly as the linear energy transfer(LET) increases for both n-type and p-type FinFET hits,but the single event transient(SET) pulse width is not linear with the incidence LET and the increasing rate will gradually reduce as the LET increases.The impacts of wafer thickness on the charge collection are also analyzed,and it is shown that a larger thickness can bring about stronger charge collection.Thus reducing the wafer thickness could mitigate the SET effect for FinFET technology.QIN JunRui CHEN ShuMing CHEN JianJun 2012Science China(Technological Sciences)2012,55,6:3

13Carboniferous Highly Fractionated I-type Granites from the Kalamaili Fault Zone, Eastern Xinjiang, NW China: Petrogenesis and Tectonic Implications显示文摘Carboniferous magmatism is one of the most important tectonothermal events in the Central Asian Orogenic Belt(CAOB). However, the final closure time of the Kalamaili Ocean between East Junggar and Harlik Mountain is still debated. Early Carboniferous(332 Ma) and late Carboniferous(307-298 Ma) granitic magmatism from Kalamaili fault zone have been recognized by LA-ICP-MS zircon U-Pb dating. They are both metaluminous highly fractionated I-type and belong to the high-K calc-alkaline. The granitoids for early Carboniferous have zircon εHf(t) values of-5.1 to +8.5 with Hf model ages(TDM2) of 1.78-0.83 Ga, suggesting a mixed magma source of juvenile material with old continental crust. Furthermore, those for late Carboniferous have much younger heterogeneous zircon εHf(t) values(+5.1 to +13.6) with Hf model ages(TDM2=1.03-0.45 Ga) that are also indicative of juvenile components with a small involvement of old continental crust. Based on whole-rock geochemical and zircon isotopic features, these high-K granitoids were derived from melting of heterogeneous crustal sources or through mixing of old continental crust with juvenile components and minor AFC(assimilation and fractional crystallization). The juvenile components probably originated from underplated basaltic magmas in response to asthenospheric upwelling. These Carboniferous highly fractionated granites in the Kalamaili fault zone were probably emplaced in a post-collisional extensional setting and suggested vertical continental crustal growth in the southern CAOB, which is the same or like most granitoids in CAOB. This study provides new evidence for determining the post-accretionary evolution of the southern CAOB. In combination with data from other granitoids in these two terranes, the Early Carboniferous Heiguniangshan pluton represents the initial record of post-collisional environment, suggesting that the final collision between the East Junggar and Harlik Mountain might have occurred before 332 Ma.SONG Peng WANG Tao TONG Ying ZHANG Jianjun HUANG He ZHANG Lei QIN Qie SHEN Huan 2019Acta Geologica Sinica(English Edition)2019,93,5:2
14A new electroplated Ir/Ir(OH)_x pH electrode and its application in the coastal areas of Newport Harbor, California显示文摘Resulting from the rising levels of atmospheric carbon, ocean acidification has become a global problem. It has significant impacts on the development, survival, growth and physiology of marine organisms. Therefore, a highprecision sensor is urgently needed to measure the pH of sea-water. Iridium wire with a diameter of 0.25 mm is used as the substrate, and an Ir/Ir(OH)_x pH electrode is prepared by a one-step electrochemical method in a Li OH solution at the room temperature. A scanning electron microscope(SEM) observation reveals that it is coated with nanoscale particles. In laboratory tests, the electrode exhibits a very promising pH response, with an ideal Nernst slope(56.14–59.52), fast response, good stability and long life-span in tested pH buffer solutions. For a sea trial,four pH electrodes and one Ag/Ag Cl reference electrode are integrated with a self-made chemical sensor, and a profile detection of nearly 70 m is implemented near Newport Harbor, California on August 3, 2015. The results reflect that the pH value measured by the sensor is very close to the data given by Sea-Bird 911 plus CTD, with a difference value ranging from 0.000 075 to 0.064 719. And the sensor shows a better data matching degree in 0–40m water depth. In addition, the high precision and accuracy of the sensor make it possible to use in the ocean observation field.ZHANG Xiao YE Ying KAN Yating HUANG Yuanfeng JIA Jianjun ZHAO Yue CHEN Chen-Tung Arthur QIN Huawei 2017Acta Oceanologica Sinica2017,36,5:2
