1Emission inventories of primary particles and pollutant gases for China显示文摘Detailed high-resolution emission inventories of primary particles(PM2.5,BC and OC) and pollutant gases(SO2,NOx,NH3,CO and VOCs) for China in 2007 were constructed on the basis of the latest fuel consumption data,mostly at the county level,and from socio-economic statistics and data on fossil and biomass fuels obtained from government agencies.New emission factors reflecting local features were also used.The calculated emissions were 13.212 Mt PM2.5,1.4 Mt BC,2.946 Mt OC,31.584 Mt SO2,23.248 Mt NOx,16.017 Mt NH3,164.856 Mt CO and 35.464 Mt VOCs.The national and regional emissions were gridded with 0.5°× 0.5° resolution for use in air quality models.Larger emissions were found in eastern and central China than in western China.The emissions estimated here are roughly equal to those obtained in previous studies,but with different contributions from because of seasonal changes in residential heating and biomass combustion.Finally,uncertainties in inventories were analyzed.CAO GuoLiang ZHANG XiaoYe GONG SunLing AN XinQin WANG YaQiang 2011Chinese Science Bulletin2011,56,8:64
2Estimation of emissions from field burning of crop straw in China显示文摘Emissions resulting from crop straw field burning in China, which have caused serious environmental problems in China, are estimated in this paper. From the county-level data of crop production in 2000― 2003 from the government statistics, taking into account the ratio of residue and grain, the total amount of crop straw production is estimated to be about 600 Tg per year, 76% of which are rice, wheat and corn straw. With reference to the data of living standards, the percentage of crop straw burnt in fields for counties are obtained and consequently the total amount of burnt straws is approximately 140 Tg/year. With the emission factors from literature and experiments, appropriate emission factors have been obtained. The total amounts of PM, SO_2, NO_x, NH_3, CH_4, BC, OC, VOC, CO, CO_2 emissions from field burning of crop straw in China are estimated. All emissions are presented at county level. Some pollutants, such as BC, VOC, OC, CO and CO_2, are contributing a major portion to the total emissions of China. This paper uses a map with resolution of 0.2°×0.2° to present the PM emissions distribution from crop straw burnt in 2003. The results show a significant regional unevenness of emissions, with larger amounts of pollutions coming from the provinces in eastern and northeast China. The regions with higher emissions per unit area are located as a belt stretching from northeast China to eastern China.CAO GuoLiang ZHANG XiaoYe WANG YaQiang Zheng FangCheng 2008Chinese Science Bulletin2008,53,5:38
3Current status of diagnosis and treatment of bladder cancer in China-Analyses of Chinese Bladder Cancer Consortium database显示文摘Objective:To investigate current status of diagnosis and treatment of bladder cancer in China.Methods:A database was generated by Chinese Bladder Cancer Consortium(CBCC).From January 2007 to December 2012,14,260 cases from 44 CBCC centers were included.Data of diagnosis,treatment and pathology were collected.Results:The average age was 63.5 year-old and most patients were male(84.3%).The most common histologic types were urothelial carcinoma(91.4%),adenocarcinoma(1.8%),and squamous carcinoma(1.9%).According to 1973 and 2004 WHO grading system,42.0%,41.0%,and 17.0% of patients were grade 1,2,and 3,and 16.0%,48.7%,and 35.3% of patients were papillary urothelial neoplasms of low malignant potential,low,and high grade,respectively.Non-muscle invasive bladder cancer(NMIBC)and muscle invasive bladder cancer(MIBC)were 25.2% and 74.1%,respectively(0.8% not clear).Carcinoma in situ was only 2.4%.Most patients were diagnosed by white-light cystoscopy with biopsy(74.3%).Fluorescence and narrow band imaging cystoscopy had additional detection rate of 1.0% and 4.0%,respectively.Diagnostic transurethral resection(TUR)provided detection rate of 16.9%.Most NMIBCs were treated with TUR(89.2%).After initial TUR,2.6%accepted second TUR,and 45.7%,69.9%,and 58.7% accepted immediate,induced,and maintenance chemotherapy instillation,respectively.Most MIBCs were treated with radical cystectomy(RC,59.7%).Laparoscopic RCs were 35.1%,while open RC 63.4%.Extended and standard pelvic lymph node dissection were 7% and 66%,respectively.Three most common urinary diversions were orthotopic neobladder(44%),ileal conduit(31%),and ureterocutaneostomy(23%).Only 2.3% of patients accepted neo-adjuvant chemotherapy and only 18%of T3 and T4 patients accepted adjuvant chemotherapy.Conclusion:Disease characteristics are similar to international reports,while differences of diagnosis and treatment exist.This study can provide evidences for revisions of the guideline on bladder cancer in China.Kaiwen Li Tianxin Lin Wei Xue Xin Mu Enci Xu Xu Yang Fubao Chen Guangyong Li Lulin Ma Guoliang Wang Chaozhao Liang Haoqiang Shi Ming Li Mao Tang Xueyi Xue Yisong Lv Yaoliang Deng Chengyang Li Zhiwen Chen Xiaozhou Zhou Fengshuo Jin Xudong Liu Jinxin Wei Lei Shi Xin Gou Weiyang He Liqun Zhou Lin Cai Baiye Jin Guanghou Fu Xiangbo Kong Hongyan Sun Ye Tian Lang Feng Tiejun Pan Yiyi Wu Dongwen Wang Hailong Hao Benkang Shi Yaofeng Zhu Qiang Wei Ping Han Changli Wu Dawei Tian Zhangqun Ye Zheng Liu Zhiping Wang Junqiang Tian Lin Qi Minfeng Chen Wei Li Jinchun Qi Gongxian Wang Longlong Fu Zhaolin Sun Guangheng Luo Zhoujun Shen Zhaowei Zhu Jinchun Xing Zhun Wu Dong Wei Xin Chen Yanqun Na Hongfeng Guo Chunxi Wang Zhihua Lu Chuize Kong Yang Liu Jin Yang Jianyun Hu Xin Gao Jielin Li Changjun Yin Pu Li Shan Chen Zhen Du Jiongming Li Yongji Yan Xu Zhang Shuang Huang Fangjian Zhou Zhiling Zhang Yinghao Sun Shuxiong Zeng Song Cen Jiaquan Zhou Hanzhong Li Jin Wen Jian Huang 2015Asian Journal of Urology2015,2,2:21
4Geochemical and isotopic characteristics of volcanic rocks from the northern East China Sea shelf margin and the Okinawa Trough显示文摘Volcanic rocks both from the northern East China Sea (NECS) shelf margin and the northern Okinawa Trough are subalkaline less aluminous,and lower in High Field Strength Elements (HFSE).These rocks are higher in Large Ion Lithophile Elements (LILE),thorium and uranium contents,positive lead anomalies,negative Nb-Ta anomalies,and enrichment in Light Rare Earth Elements (LREE).Basalts from the NECS shelf margin are akin to Indian Ocean Mid-Ocean Ridge Basalt (MORB),and rhyolites from the northern Okinawa Trough have the highest 207 Pb/ 204 Pb and 208 Pb/ 204 Pb ratios.The NECS shelf margin basalts have lower 87 Sr/ 86 Sr ratios,ε N d and σ 18 O than the northern Okinawa Trough silicic rocks.According to 40 K– 40 Ar isotopic ages of basalts from the NECS shelf margin,rifting of the Okinawa Trough may have been active since at least 3.65–3.86 Ma.The origin of the NECS shelf margin basalt can be explained by the interaction of melt derived from Indian Ocean MORB-like mantle with enriched subcontinental lithosphere.The basalts from both sides of the Okinawa Trough may have a similar origin during the initial rifting of the Okinawa Trough,and the formation of basaltic magmas closely relates to the thinning of continental crust.The source of the formation of the northern Okinawa Trough silicic rocks was different from that of the middle Okinawa Trough,which could have been generated by the interaction of basaltic melt with an enriched crustal component.From the Ryukyu island arc to East China,the Cenozoic basalts have apparently increasing trends of MgO contents and ratios of LREE to Heavy Rare Earth Elements (HREE),suggesting that the trace element variabilities of basalts may have been influenced by the subduction of the Philippine Sea plate,and that the effects of subduction of the Philippine Sea plate on the chemical composition of basaltic melts have had a decreasing effect from the Ryukyu island arc to East China.ZENG Zhigang YU Shaoxiong WANG Xiaoyuan FU Yongtao YIN Xuebo ZHANG Guoliang WANG Xiaomei CHEN Shuai 2010Acta Oceanologica Sinica2010,29,4:19
5GYY4137 protects against myocardial ischemia and reperfusion injury by attenuating oxidative stress and apoptosis in rats显示文摘Hydrogen sulfide(H_2S) is a gasotransmitter that regulates cardiovascular functions.The present study aimed to determine the protective effect of slow-releasing H_2S donor GYY4137 on myocardial ischemia and reperfusion(I/R) injury and to investigate the possible signaling mechanisms involved.Male Sprague-Dawley rats were treated with GYY4137 at 12.5 mg/(kg·day),25 mg/(kg·day) or 50 mg/(kg·day) intraperitoneally for7 days.Then,rats were subjected to 30 minutes of left anterior descending coronary artery occlusion followed by reperfusion for 24 hours.We found that GYY4137 increased the cardiac ejection fraction and fractional shortening,reduced the ischemia area,alleviated histological injury and decreased plasma creatine kinase after myocardial I/R.Both H_2S concentration in plasma and cystathionine-γ-lyase(CSE) activity in the myocardium were enhanced in the GYY4137 treated groups.GYY4137 also decreased malondialdehyde and myeloperoxidase levels in serum,attenuated superoxide anion level and suppressed phosphorylation of mitogen activated protein kinases in the myocardium after I/R.Meanwhile,GYY4137 increased the expression of Bcl-2 but decreased the expression of Bax,caspase-3 activity and apoptosis in the myocardium.The data suggest that GYY4137 protects against myocardial ischemia and reperfusion injury by attenuating oxidative stress and apoptosis.Guoliang Meng Jing Wang Yujiao Xiao Wenli Bai Liping Xie Liyang Shan Philip K Moore Yong Ji 2015The Journal of Biomedical Research2015,29,3:18
6Efficacy of Banxia Xiexin decoction in a rat model of chronic atrophic gastritis显示文摘OBJECTIVE:To investigate the effectiveness of Banxia Xiexin decoction(BXD)in a rat model of chronic atrophic gastritis(CAG).METHODS:Sixty 6-week-old healthy Wistar rats(30 males,30 females)were used in the present study.A rat model of CAG was successfully established using the combined active immunization/ethanol/sodium deoxycholate method.BXD was prepared from a mixture of seven Chinese herbs,and was intragastrically administered to CAG rats at three different doses(6,12,and 24 g·kg^-1·d^-1).Af-ter 24 weeks,the rats were euthanized,and gastric tissue specimens were collected.Gastric mucosal specimens were stained with hematoxylin and eosin for histological examination to evaluate the degree of inflammation and morphological changes.Immunohistochemical staining was performed to examine the mucosal expression of proliferating cell nuclear antigen.Serum gastrin levels were measured using radioimmunoassay.The expression of Notch signaling-associated genes was examined by quantitative polymerase chain reaction and Western blot assay.RESULTS:BXD at all three doses significantly reversed the adverse effects generated by CAG in rats.Compared with control rats,the CAG rats who were administered BXD had an accelerated growth rate,reduced inflammatory cell infiltration,improved gastric mucosal morphology,augmented thickness of the gastric mucosa,increased number of gastric glands,enhanced mucosal expression of proliferating cell nuclear antigen,and elevated serum gastrin levels.Bai Yu Chen Yongcan Chen Yu Yan Maoxiang Wei Hongquan Wang Hengcang Zeng Guoliang Yang Xiyin 2019Journal of Traditional Chinese Medicine2019,39,6:14
7Formation of Fe-oxyhydroxides from the East Pacific Rise near latitude 13°N:Evidence from mineralogical and geochemical data显示文摘The mineralogical and geochemical characteristics of Fe-oxyhydroxide samples from one dredge station (long. 103°54.48'W, lat. 12°42.30'N, water depth 2655 m) on the East Pacific Rise near lat 13°N were analyzed by XRD, ICP-AES, and ICP-MS. Most Fe-oxyhydroxides are amorphous, with a few sphalerite microlites. In comparison with Fe-oxyhydroxides from other fields, the variable ranges in the chemical composition of Fe-oxyhydroxide samples are very narrow; their Fe, Si, and Mn contents were 39.90%, 8.92%, and 1.59%, respectively; they have high Cu (0.88%―1.85%) and Co (65×10?6―704×10?6) contents, and contain Co+Cu+Zn+Ni> 1.01%. The trace-element (As, Co, Ni, Cu, Zn, Ba, Sr) and major-element (Fe, Ca, Al, Mg) contents of these samples are in the range of hydrothermal sulfide from the East Pacific Rise near 13°N, reflecting that this type of Fe-oxyhydroxide constitutes a secondary oxidation product of hydrothermal sulfide. The Fe-oxyhydroxide samples from one dredge station on the East Pacific Rise near 13°N are lower in ΣREE (5.44×10?6―17.01×10?6), with a distinct negative Ce anomaly (0.12 ― 0.28). The Fe-oxyhydroxide samples have similar chondrite-normalized rare-earth-element (REE) patterns to that of seawater, and they are very different from the REE composition characteristics of hydrothermal plume particles and hydrothermal fluids, showing that the REEs of Fe-oxyhydroxide are a major constituent of seawater and that the Fe-oxyhydroxides can become a sink of REE from seawater. The quick settling of hydrothermal plume particles resulted in the lower REE content and higher Mn content of these Fe-oxyhydroxides, which are captured in part of the V and P from seawater by adsorption. The Fe-oxyhydroxides from one dredge station on the East Pacific Rise near 13°N were formed by secondary oxidation in a low temperature, oxygenated environment. In comparison with the elemental (Zn, Cd, Pb, Fe, Co, Cu) average content of hydrothermal sulfide samples from the East Pacific Rise near 13°N, the Zn, Cd, and Pb contents of the Fe-oxyhydroxides are lower, and their Fe, Co, and Cu contents are higher.ZENG ZhiGang WANG XiaoYuan ZHANG GuoLiang YIN XueBo CHEN DaiGeng WANG XiaoMei 2008Science China Earth Sciences2008,51,2:12
8Late Quaternary glacial chronology on the eastern slope of Gongga Mountain,eastern Tibetan Plateau,China显示文摘The Gongga Mountain is the largest area of modern glaciation in the Hengduan Mountains and,with a summit elevation of 7556 m,is the highest mountain on the eastern margin of the Tibetan Plateau.During the Quaternary glacial-interglacial cycles the Gongga Mountain was extensively and repeatedly glaciated,and glacial landforms and outwash deposits from multiple glaciations are well-preserved in valleys,in basins,and on piedmonts.To constrain the glacial chronology of the eastern slope of Gongga Mountain,sample sites were selected based on the distribution and weathering of glacial tills,relationships among glacial deposits,and soil development on moraines.Dating of the tills and glaciofluvial deposits was undertaken with electron spin resonance(ESR) and optically stimulated luminescence(OSL).The ages of the glacial deposits can be divided into four clusters:2.2±0.5,11.9±0.6,35.9±2.7-58.0±6.3 and 119.2±15.9-194.2±32.8 ka.Five glacial advances in this region have been identified,which are equivalent in age to the Little Ice Age(LIA),Neoglaciation,marine oxygen isotope stage(MIS) 2,mid-MIS3,and MIS6.The largest local last glacial maximum(LGML) occurred on Gongga Mountain during mid-MIS3,characterized by a cold-humid climate,rather than the global Last Glacial Maximum(LGMG) of MIS2.The Gongga,Nanmenguangou(NMGG) and Yajiageng Glaciations occurred during the late part of the last glacial cycle,the middle of the last glacial cycle and the penultimate glacial cycle,respectively.On the basis of geomorphological,sedimentological,and compositional characteristics,landforms of the Moxi Platform and terraces can be grouped by facies and geochronology.In combination with the dating results,this analysis indicates the basal part of the Moxi Platform between Xinxin and the Moxi Hotel is correlative with the till of the Nanguanmen Glaciation(mid-MIS3).This basal unit has occasional lenses of glaciofluvial sandy gravel and lacustrine sediments.The remainder of the Moxi Platform and the terraces beside the platform are glaciofluvial deposits occasionally mixed with debris flow deposits and range in age from MIS3 to Holocene.WANG Jie PAN BaoTian ZHANG GuoLiang CUI Hang CAO Bo GENG HaoPeng 2013Science China Earth Sciences2013,56,3:11
9Laser-MIG Arc Hybrid Brazing-Fusion Welding of Al Alloy to Galvanized Steel with Different Filler Metals显示文摘Aluminum alloy plates were joined to galvanized steel sheets with lap joint by laser-MIG arc hybrid brazing- fusion welding with AlSi5, AlSi12, AlMg5 filler wires, respectively. The influences of Si and Mg on the microstructure and mechanical properties of the brazed-fusion welded joint were studied. The increase of Si element in the fusion weld can make the grain refined, and increase the microhardness of the fusion weld. Therefore, the microhardness in fusion weld made from AlSi12 and AlSi5 filler wires can be up to 98.4 HV0.01 and 96.8 HV0.01, which is higher than that from AlMg5 filler wire of 70.4 HV0.01. The highest tensile strength can reach 178.9 MPa made with AlMg5 filler wire. The tensile strength is 172.43 MPa made with AlSi5 filler wire. However, the lowest tensile strength is 144 MPa made with AlSi12 filler wire. The average thicknesses of the intermetallic compounds (IMCs) layer with ,AlSi5 AlSi12, AlMg5 filler wires are 1.49-2.64 μm. The IMCs layer made from AlSi5, AlSi12 filler wires are identified as FeAl2, Fe2Al5 , Fe4 Al13 and Al0.5Fe3Si0.5, that from AlMg5 filler wire are identified as FeAl2 , Fe2Al5 and Fe4Al13.Shujun WANG Guoliang QIN Yuhu SU 2013Acta Metallurgica Sinica(English Letters)2013,26,2:10
10Climatic and environmental implications from n-alkanes in glacially eroded lake sediments in Tibetan Plateau:An example from Ximen Co显示文摘Gas chromatography-mass spectrometry was used to identify a series of n-alkanes in the sediments of a typical glacially eroded lake in the eastern Tibetan Plateau.By comparing the distribution patterns of n-alkanes in lake sediments,surface soils and cow manure,it was shown that n-C 27-n-C 33 alkanes in the soil ecosystem of Ximen Co are derived from vascular plant species and that the distribution pattern of n-C 27-n-C 33 alkanes remains unchanged during the feeding and digestion processes of herbivores.The relative percentage of C 27,C 29 and C 31 n-alkanes decreased from the bottom to the top of the sediment core showing a trend of degradation of higher plants in the Ximen Co lake region during the formation of the 44 cm core.210 Pb dating,combined with pre-existing AMS 14 C dating results showed that the depositional core reflects climatic and environmental variations since about 900 years before present.The n-alkane indexes (ACL 27-33,P aq,P wax) are comparable with regional temperature variation,especially recording the Little Ice Age event (LIA).This study highlights that n-alkanes are valid proxies for paleo-climate and paleo-environment reconstruction,despite the same distribution patterns in n-alkane molecular fossils derived from a typical glacially eroded lake.PU Yang ZHANG HuCai WANG YongLi LEI GuoLiang NACE Trevor ZHANG ShuPing 2011Chinese Science Bulletin2011,56,14:10
11Palladium Nanoparticle-Graphene Hybrids as Active Catalysts for the Suzuki Reaction显示文摘Graphene has been successfully modified with palladium nanoparticles in a facile manner by reducing palladium acetate [Pd(OAc)2] in the present of sodium dodecyl sulfate (SDS), which is used as both surfactant and the reducing agent. The palladium nanoparticle-graphene hybrids (Pd-graphene hybrids) are characterized by high- resolution transmission electron microscopy, atomic force microscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, X-ray diffraction, and energy dispersive X-ray spectroscopy. We demonstrate that the Pd-graphene hybrids can act as an efficient catalyst for the Suzuki reaction under aqueous and aerobic conditions, with the reaction reaching completion in as little as 5 min. The influence of the preparation conditions on the catalytic activities of the hybrids is also investigated.Yang Li Xiaobin Fan Junjie Qi Junyi Ji Shulan Wang Guoliang Zhang Fengbao Zhang 2010Nano Research2010,3,6:10
12Effect of heat treatment on mechanical properties of heavily cold-rolled Fe-6.5wt%Si alloy sheet显示文摘Fe-6.5wt%Si alloy has excellent soft magnetic properties,but it is hard to be cold-rolled due to appearance of ordered phases in this alloy.In this paper we report that ultra thin Fe-6.5wt%Si sheet of 0.05 mm thick was obtained by heavily cold rolling.By means of optical microscope,micro-hardness indenter,instron,SEM and X-ray diffraction,the effect of heat treatment on mechanical properties of this alloy sheet was investigated.The heavily cold-rolled sheet exhibits some extent of ductility.The ultimate tensile strength reaches 1.93 GPa.After heat treatment,micro-hardness is decreased and the ductility is lost,especially at temperature above 650℃ when recrystallization takes place.The reason for decreasing the ductility lies in the ordered DO3 phase transformation.LIANG YongFeng,YE Feng,LIN JunPin,WANG YanLi,ZHANG LaiQi & CHEN GuoLiang State Key Laboratory for Advanced Metals and Materials,University of Science and Technology Beijing,Beijing 100083,China 2010Science China(Technological Sciences)2010,53,4:10
13Minor alloying behavior in bulk metallic glasses and high-entropy alloys显示文摘The effect of minor alloying on several bulk metallic glasses and high-entropy al-loys was studied. It was found that minor Nb addition can optimize the interface structure between the W fiber and the Zr-based bulk metallic glass in the compos-ites,and improve the mechanical properties. Minor Y addition can destabilize the crystalline phases by inducing lattice distortion as a result to improve the glass-forming ability,and the lattice distortion energy is closely related to the effi-ciency of space filling of the competing crystalline phases. A long-period ordered structure can precipitate in the Mg-based bulk metallic glass by yttrium alloying. For the high-entropy alloys,solid solution can be formed by alloying,and its me-chanical properties can be comparable to most of the bulk metallic glasses.ZHANG Yong ZHOU YunJun HUI XiDong WANG MeiLing CHEN GuoLiang 2008Science China(Physics,Mechanics & Astronomy)2008,51,4:10
14A review of flexible perovskite oxide ferroelectric films and their application显示文摘Many perovskite oxide ferroelectrics(e.g.PbZr_(1-x)Ti_(x)O_(3),BaTiO_(3),LiNbO_(3))are born with multitudinous robust performances and have been widely used in sensors,actuators,surface acoustic wave devices,and memories et al.However,their hardness,brittleness and harsh synthesis conditions(i.e.high temperature and oxygen ambience)restrain their application into flexible electronic devices which are significant components among the three pillars of modern society development,i.e.energy,information and materials.Here we review the preparation of flexible devices based on these oxide ferroelectrics,including transferring these freestanding films to flexible substrates after separating ferroelectric oxide films from the hard substrates,such as Si and SrTiO_(3) crystals,and also direct fabrication methods without transferring process.Subsequently,we summarize three kinds of representative flexible devices,i.e.flexible ferroelectric memories,sensors and generators.These inorganic electronics not only show excellent electric properties competitive with those corresponding electronics on hard substrates but also exhibit good flexibility similar to many organic flexible electronics.Wenxiu Gao Yi Zhu Yaojin Wang Guoliang Yuan Jun-Ming Liu 2020Journal of Materiomics2020,6,1:9

16Dendrite-free all-solid-state lithium batteries with lithium phosphorous oxynitride-modified lithium metal anode and composite solid electrolytes显示文摘Dendrite formation on lithium (Li) metal anode is a key issue which hinders the development of rechargeable Li battery seriously. A novel method for suppress!ng Li dendrites via using Li phosphorous oxynitride (UPON) modified Li anode and Li1.5Al0.5Ge1.5(PO4)3-poly(ethylene oxide)(Li bistrifluoromethane-sulfonimide)(LAGP-PEO(LiTFSI)) composite solid electrolyte in all-solid-state Li battery is proposed, and the effect of the thickness of UPON on Li anode performarice is also studied. LiPON film with a thickness of 500 nm exhibits satisfactory interface property between Li metal anode and the LAGP-PEO(LiTFSI) solid electrolyte. The LiPON film provides a uniform Li^+ flux across the interface and effectively inhibits the formation of Li dendrites in all-solid-state Li batteries. The assembled all-solid-state Li cell Li(LiPON)/LAGP-PEO(LiTFSI)/LiFePO4 delivers an initial discharge capacity of 152.4 mAh·g^-1 and exhibits good cycling stability and rate performanee at 50 ℃.Chunhua Wang Guoliang Bai Yifu Yang Xingjiang Liu Huixia Shao 2019Nano Research2019,12,1:8
17Receptome profiling identifies KREMEN1 and ASGR1 as alternative functional receptors of SARS-CoV-2显示文摘Host cellular receptors play key roles in the determination of virus tropism and pathogenesis.However,little is known about SARS-CoV-2 host receptors with the exception of ACE2.Furthermore,ACE2 alone cannot explain the multi-organ tropism of SARS-CoV-2 nor the clinical differences between SARS-CoV-2 and SARS-CoV,suggesting the involvement of other receptor(s).Here,we performed genomic receptor profiling to screen 5054 human membrane proteins individually for interaction with the SARS-CoV-2 capsid spike(S)protein.Twelve proteins,including ACE2,ASGR1,and KREMEN1,were identified with diverse S-binding affinities and patterns.ASGR1 or KREMEN1 is sufficient for the entry of SARS-CoV-2 but not SARS-CoV in vitro and in vivo.SARS-CoV-2 utilizes distinct ACE2/ASGR1/KREMEN1(ASK)receptor combinations to enter different cell types,and the expression of ASK together displays a markedly stronger correlation with virus susceptibility than that of any individual receptor at both the cell and tissue levels.The cocktail of ASK-related neutralizing antibodies provides the most substantial blockage of SARS-CoV-2 infection in human lung organoids when compared to individual antibodies.Our study revealed an interacting host receptome of SARS-CoV-2,and identified ASGR1 and KREMEN1 as alternative functional receptors that play essential roles in ACE2-independent virus entry,providing insight into SARS-CoV-2 tropism and pathogenesis,as well as a community resource and potential therapeutic strategies for further COVID-19 investigations.Yunqing Gu Jun Cao Xinyu Zhang Hai Gao Yuyan Wang Jia Wang Juan He Xiaoyi Jiang Jinlan Zhang Guanghui Shen Jie Yang Xichen Zheng Gaowei Hu Yuanfei Zhu Shujuan Du Yunkai Zhu Rong Zhang Jianqing Xu Fei Lan Di Qu Guoliang Xu Yun Zhao Dong Gao Youhua Xie Min Luo Zhigang Lu 2022Cell Research2022,32,1:8
18Toward artificial intelligent self-cooling electronic skins:Large electrocaloric effect in all-inorganic flexible thin films at room temperature显示文摘Intelligent robots have assisted mankind in achieving and operating thousands of functions,especially with the arrival of the artificial intelligent.However,heat dissipation and thermal management in the intelligent robots remain big challenges,which limit their miniaturization and performance.Electrocaloric(EC)materials,which exhibit temperature change in response to the application or withdrawal of an electric field,open a new strategy for cooling technology and have gained a flurry of research interest in recent years.Toward artificial intelligent self-cooling electronic skins,large-scale flexible materials with high EC effect near room temperature are in demand.Here,we report a large room temperature EC effect in flexible Pb_(0.82)Ba_(0.08)La_(0.1)Zr0.9Ti_(0.1)O_(3)(PBLZT)inorganic thin films via a transfer-free cost-effective sol-gel process,assisted by unique two-dimensional mica substrates.The maximum adiabatic temperature change and isothermal entropy change of the flexible PBLZT thin films reach to 22.5 K and 25.9 J K^(-1) kg^(-1) at room temperature.In particular,the flexible PBLZT thin films exhibit a stable EC effect both under bending state and after bending for 20000 times.Our flexible EC materials offer an alternative strategy to the development of cooling technologies for both artificial intelligent robots and personal wearable cooling devices.Ding Wang Xin Chen Guoliang Yuan Yanmin Jia Yiping Wang Arif Mumtaz Yaojin Wang Jun-Ming Liu 2019Journal of Materiomics2019,5,1:7

20Tensor force effect on proton shell structure in neutron-rich Ca isotopes显示文摘In the framework of the Skyrme-Hartree-Fock approach with 36 sets of the TI J parameterizations,the tensor force effect on the evolution of the single-proton states in the calcium isotopes is systematically investigated.It is shown that the single-proton states with higher angular momenta are influenced significantly by the tensor force and the trend in the evolution of somesingle-particle energy differences with the mass number of the isotopes depends sensitively on a parameter βT associated with the intensity of the tensor force.To understand this phenomenon,we analyze the spin-orbit potentials and the radial wave functions of relevant single-proton orbits in detail.In addition,it is found that some TI J interactions could cause the 2s1/21d3/2 energy level inversion in 48Ca.LI ZhenYu WANG YanZhao YU GuoLiang GU JianZhong 2013Science China(Physics,Mechanics & Astronomy)2013,56,9:7
