| 1 | Polysaccharides from Angelica sinensis alleviate neuronal cell injury caused by oxidative stress显示文摘Angelica sinensis has antioxidative and neuroprotective effects. In the present study, we aimed to determine the neuroprotective effect of polysaccharides isolated from Angelica sinensis. In a preliminary experiment, Angelica sinensis polysaccharides not only protected PC12 neuronal cells from H 2 O 2-induced cytotoxicity, but also reduced apoptosis and intracellular reactive oxygen species levels, and increased the mitochondrial membrane potential induced by H 2 O 2 treatment. In a rat model of local cerebral ischemia, we further demonstrated that Angelica sinensis polysaccharides enhanced the antioxidant activity in cerebral cortical neurons, increased the number of microvessels, and improved blood flow after ischemia. Our findings highlight the protective role of polysaccharides isolated from Angelica sinensis against nerve cell injury and impairment caused by oxidative stress. | Tao Lei Haifeng Li Zhen Fang Junbin Lin Shanshan Wang Lingyun Xiao Fan Yang Xin Liu Junjian Zhang Zebo Huang Weijing Liao | 2014 | Neural Regeneration Research2014，9，3： | 17 |

| 3 | Comprehensive eco-environmental effects of the shelter-forest ecological engineering along the Tarim Desert Highway显示文摘In this work, we report a comprehensive study about the eco-environmental effects of the shelter forest along the Tarim Desert Highway, including the effects on aeolian environment, soil, micro-climate, biodiversity, and groundwater. The results show that: (1) The movement of windblown sand near the ground surface was affected by the shelter forest. The wind speed and sediment transport rate in the shelter forest decreased by 64%―80% and 87.45%―99.02%, respectively. In addition, there were also significant changes in the sand flux structure, the sand grain size, and the deflation and deposition on the ground surface. (2) Compared to the natural mobile sand, the soil bulk density in the forest area decreased while the total salt content, the total porosity, and the water content increased. In addition, the soil fertility was significantly improved in the forest area, and showed the 'first rapid, then slow' variation pattern. (3) The shelter forest showed positive effects on the micro-climate. Within the 6 m height above the ground, the air temperature in the shelter forest at different heights was lower than that in the mobile sand, while the air humidity was higher, while, the soil temperature was also lower in the shelter forest than mobile sand. (4) The number of soil microbial species increased significantly with the improvement of habitat in the shelterbelt. However, the population of different species was not distributed evenly across the surveyed area. (5) Currently, no significant effects of groundwater-pumping and forest-irrigation water have been found on the groundwater level and its salinity. The variation amplitude of both groundwater level and salinity was at the level of centimeters and 1g/L, respectively. No obvious variation trend has been observed. | LEI JiaQiang LI ShengYu JIN ZhengZhong FAN JingLong WANG HaiFeng FAN DongDong ZHOU HongWei GU Feng QIU YongZhi XU Bo | 2008 | Chinese Science Bulletin2008，53，S2： | 14 |
| 4 | Characteristics of Cd isotopic compositions and their genetic significance in the lead-zinc deposits of SW China显示文摘Up to now,the evaporation and condensation,as well as the biological absorption and inorganic absorptions,have been proved to be major factors in Cd isotope fractionation.And Cd isotopes have been widely applied in studies on the universal evolution and marine environment and so on.However,only a few researches have been conducted in applying Cd isotopes to trace the source of metallogenic material and the evolution of the ore-forming fluid in a complex mineralization environment,especially in a hydrothermal ore-formation system.We measured the Cd isotopic compositions of sphalerite,galena,and ores from five lead-zinc deposits in SW China,and found that the 114/110Cd values varied from 1.53‰to 0.34‰,with a total range of1.87‰,which is greater than most of measured geological samples.Meanwhile,through contrasting the Cd content with Cd isotopic compositions of different deposits,it may be concluded that different genetic lead-zinc deposits have different Cd content and isotopic compositions,which could be a tool for the studies on the origin of ore deposits.Also,the biomineralization and crystal fractionation may also result in Cd isotope fractionation.In a word,although the research of Cd isotopes is presently at the preliminary stage(especially in hydrothermal ore-formation system),this study demonstrated that Cd isotopes can give a clue in tracing the evolution of ore-forming fluid and metallogenic environment. | ZHU ChuanWei WEN HanJie ZHANG YuXu FAN HaiFeng FU ShaoHong XU Juan QIN TingRong | 2013 | Science China Earth Sciences2013，56，12： | 14 |
| 5 | Insulin improves cardiac myocytes contractile function recovery in simulated ischemia-reperfusion:Key role of Akt显示文摘The present study examined cardiac myocytecontractile and Ca2+ transient responses to insulin duringsimulated ischemia/reperfusion (I/R) and furtherinvestigated the role of protein kinase B (Akt) in the insulin-induced inotropic effect. Ventricular myocytes wereenzymatically isolated from adult Sprague-Dawley rats and perfused with Tyrode solution while electrically field-stimulated. Simulated I/R was induced by perfusing the cells with chemical anoxic solution including sodiumcyanide-sodium lactate for 15 min followed by reperfusionwith normal oxygenated Tyrode solution with or withoutinsulin. It is found that insulin only at concentration as high as 10 IU/L could increase cell shortening (16±5%, P < 0.05) in normal myocytes, whereas it concentration-dependently (0.01—10 IU/L) increased the contraction,the velocity ofshortening/releng- thening and Ca2+ transient in I/Rmyocytes. In addition, insulin treatment (1 IU/L) increasedAkt phosphorylation of I/R cardiomyocytes by 2.4-foldcompared with that of the control (P < 0.01). Mostimportantly, pretreatment with LY 294002, a specificinhibitor of phosphatidylinositol 3′-kinase (PI3-kinase), significantly inhibited both Akt phosphorylation and thepositive inotropic response to insulin in the I/Rcardiomyocytes. These results suggest that insulin exertsdirect positive inotropic effect by increasing Ca2+ transient of cardiomyocytes, which is enhanced in the pathologicalcondition of I/R. Akt activation plays an important role inthe insulin-induced improvement of myocyte contractile function following I/R. | ZHANG Bo, ZHANG Haifeng, FAN Qian, MA Xinliang & GAO Feng Department of Physiology, The Fourth Military Medical University,Xi抋n 710032, China Correspondence should be addressed to Gao Feng (e-mail: fgao@fmmu.edu.cn) | 2003 | Chinese Science Bulletin2003，48，13： | 9 |
| 6 | Mo isotopes in the Lower Cambrian formation of southern China and its implications on paleo-ocean environment显示文摘Over the past decade, as one of nontraditional stable isotopes, Mo isotope has developed rapidly and now become an important geochemical proxy to trace paleo-oceanic and atmospheric evolution through geological history. In this paper, Early Cambrian formations in southern China are investigated. The results indicate that δ 97/95Mo values of Early Cambrian seawater may have been larger than 1.4‰, values that are close to those of the modern ocean. It was also found that the variations in Mo isotope composition in samples from two sections (Huangjiawan and Gezhongwu in Guizhou) were closely related to changes in redox conditions during sedimentary processes. Combining our results with existing data, a preliminary model for the evolution of seawater Mo isotope composition through geological history was provided. It indicated that Mo isotopic variations were generally consistent with the evolution of atmospheric oxygen. | WEN HanJie ZHANG YuXu FAN HaiFeng HU RuiZhong | 2009 | Chinese Science Bulletin2009，54，24： | 6 |
| 7 | The mutational pattern of homologous recombination(HR)-associated genes and its relevance to the immunotherapeutic response in gastric cancer显示文摘Objective:Currently,there is an urgent need to identify immunotherapeutic biomarkers to increase the benefit of immune checkpoint inhibitors(ICIs)for patients with gastric cancer(GC).Homologous recombination deficiency(HRD)can modify the tumor immune microenvironment by increasing the presence of tumor-infiltrating lymphocytes and therefore might serve as a biomarker of immunotherapeutic response.We aimed to analyze the mutational pattern of HR-associated genes in Chinese patients with GC and its relevance to the tumor immune profile and clinical immunotherapeutic response.Methods:A panel of 543 cancer-associated genes was used to analyze genomic profiles in a cohort comprising 484 Chinese patients with GC.Correlations between HR gene mutations and tumor immunity or clinical outcomes were identified via bioinformatic analysis using 2 GC genomic datasets(TCGA and MSK-IMPACT).Results:Fifty-one of the 484(10.54%)patients carried at least one somatic mutation in an HR gene;ATM(16/484,3.31%)was among the most frequently mutated HR genes in the Chinese cohort.Mutations in HR genes were associated with elevated tumor mutational burden,enhanced immune activity,and microsatellite instability status.In the MSK-IMPACT cohort comprising 49 patients with stomach adenocarcinoma or gastroesophageal junction adenocarcinoma treated with ICIs,patients with HR-mut GC(n=12)had significantly better overall survival than those with HR-wt GC(n=37)(log-rank test,P<0.05).Conclusions:Our data suggest that detection of somatic mutations in HR genes might aid in identifying patients who might benefit from immune checkpoint blockade therapy. | Yue Fan Haifeng Ying Xueying Wu Huan Chen Ying Hu Henghui Zhang Lijia Wu Ying Yang Beibei Mao Lan Zheng | 2020 | Cancer Biology & Medicine2020，17，4： | 6 |
| 8 | The temporal and spatial fluctuation of the groundwater level along the Tarim Desert Highway显示文摘In this work, a groundwater monitor section along the Tarim Desert Highway was set up, and the groundwater level data were recorded. The temporal and spatial fluctuations of the groundwater level were analyzed based on the groundwater level measurements, hydrologic data, the groundwater/surface water interconversion theory and the groundwater dynamics. The spatial distribution of groundwater is mostly affected by sand dune height and landform variation. The four primary temporal influence factors of groundwater level can be ordered in decreasing significance as: shelterbelt pumping > vertical leakage > river flow change > runoff replenishment. The runoff replenishment has the biggest influence range, and the shelterbelt pumping has the smallest influence range. The groundwater level fluctuates annually in a natural pattern. | FAN JingLong XU XinWen LEI JaQiang ZHAO JingFeng LI ShengYu WANG HaiFeng ZHANG JianGuo ZHOU HongWei | 2008 | Chinese Science Bulletin2008，53，S2： | 6 |
| 9 | The mixing of multi-source fluids in the Wusihe Zn–Pb ore deposit in Sichuan Province, Southwestern China显示文摘The Sichuan-Yunnan-Guizhou(SYG)metallogenic province of southwest China is one of the most important Zn-Pb ore zones in China,with^200 Mt ZnPb ores at mean grades of 10 wt.%Zn and 5 wt.%Pb.The source and mechanism of the regional Zn-Pb mineralization remain controversial despite many investigations that have been conducted.The Wusihe Zn-Pb deposit is a representative large-scale Zn-Pb deposit in the northern SYG,which mainly occurs in the Dengying Formation and yields Zn-Pb resources of^3.7 Mt.In this paper,Zn and S isotopes,and Fe and Cd contents of sphalerite from the Wusihe deposit were investigated in an attempt to constrain the controls on Zn and S isotopic variations,the potential sources of ore-forming components,and the possible mineralization mechanisms.Both theδ66Zn andδ34S values in sphalerite from the Wusihe deposit increase systematically from the bottom to the top of the strata-bound orebodies.Such spatial evolution inδ66Zn andδ34S values of sphalerite can be attributed to isotopic Rayleigh fractionation during sphalerite precipitation with temperature variations.The strong correlations between the Zn-S isotopic compositions and Fe-Cd concentrations in sphalerite suggest that their variations were dominated by a similar mechanism.However,the Rayleigh fractionation mechanism cannot explain the spatial variations of Fe and Cd concentrations of sphalerite in this deposit.It is noted that the bottom and top sphalerites from the strata-bound orebodies document contrasting Zn and S isotopic compositions which correspond to the Zn and S isotopic characteristics of basement rocks and host rocks,respectively.Therefore,the mixing of two-source fluids with distinct Zn-S isotopic signatures was responsible for the spatial variations of Zn-S isotopic compositions of sphalerite from the Wusihe deposit.The fluids from basement rocks are characterized by relatively lighter Zn(~0.2‰)and S(~5‰)isotopic compositions while the fluids from host rocks are marked by relatively heavier Zn(~0.6‰)and S(~15‰)isotopic compositions. | Hongjie Zhang Haifeng Fan Chaoyi Xiao Hanjie Wen Lin Ye Zhilong Huang Jiaxi Zhou Qingjun Guo | 2019 | Acta Geochimica2019，38，5： | 6 |
| 10 | Marine Redox Conditions in the Early Cambrian Ocean: Insights from the Lower Cambrian Phosphorite Deposits, South China显示文摘It is generally considered that a significant change in oceanic redox conditions occurred during the Ediacaran–Cambrian transition. However, there are currently two major conflicting views on the degree of oxygenation of deep water(oxic vs. ferruginous) during this interval. To date, the oxygenation conditions of the Early Cambrian ocean have not been well constrained. The oxygenation magnitude and mechanism of the Early Cambrian ocean could be critical to the significant biological evolution of the 'Cambrian Explosion'. To constrain the Early Cambrian oceanic redox environment, we conducted an integrated study on iron and sulfur isotopes and redox-sensitive elements(Mo, U, and V) of Lower Cambrian phosphorite deposits from two shallow sections(Meishucun and Gezhongwu) and a deeper water section(Zunyi) from the Yangtze Platform, South China. The near zero δ^(56)Fe values from the two shallow sections studied here reflect oxic conditions in the lower phosphorite deposition. An obvious positive shift in δ^(56)Fe and redox-sensitive element content was observed in the middle parts of the two shallow water sections, which might reflect loss of light iron by dissimilatory iron reduction during early diagenesis under suboxic shallow water in the platform. However, the highly positive δ^(56)Fe values in the deep section could reflect a lower oxidation degree of dissolved Fe(II) under anoxic deep water. The data suggest redox-stratified oceanic conditions during the Early Cambrian, in which completely oxygenated shallow water(platform) coexisted with anoxic deep water(slope). We propose that prolonged upwelling of dissolved organic carbon(DOC)-, Fe(II)- and phosphorus-rich anoxic deep water in a redox-stratified ocean could have increased exchange with the open ocean, resulting in major phosphorite deposition in oxic-suboxic conditions. The progressive oxygenation of the ocean may have facilitated the Early Cambrian biotic diversification. | Haifeng Fan Hanjie Wen Xiangkun Zhu | 2016 | Journal of Earth Science2016，27，2： | 6 |
| 11 | Large selenium isotopic variations and its implication in the Yutangba Se deposit, Hubei Province, China显示文摘The selenium isotopic ratios have been measured in the Yutangba Se deposit, Hubei Province, China. The results show that the δ 82/76SeNIST values vary from -12.77‰ to 4.93‰, which is the largest Se iso- topic variation found so far in natural terrestrial samples. The sample Ytb-5 of high-selenium carbona-ceous shale has the lightest Se isotopic composition with a δ 82/76SeNIST value of -12.77‰. On the basis of variations of Se isotope in the deposit along with other geological and geochemical evidence, the 'redox model' is suggested to favor the explanation of the occurrence of native Se in the deposit. The application to the Yutangba Se deposit with the discovery of large Se isotopic fractionation for natural samples indicates the potential of Se isotope as a new geochemical tracer. | WEN HanJie Jean CARIGNAN HU RuiZhong FAN HaiFeng CHANG Bin YANG GuangShu | 2007 | Chinese Science Bulletin2007，52，17： | 5 |
| 12 | Inorganic nitrate alleviates the senescence-related decline in liver function显示文摘Senescence-related decline in liver function is a common complication in the elderly that can lead to impaired health in older individuals.Dietary nitrate supplements have physiological and therapeutic effects on organ function by nitrate(NO_3^-)-nitrite(NO_2^-)-nitric oxide(NO)pathway.However,the role of dietary nitrate on the senescence-related decline in liver function is unclear.The findings of the present study showed that nitrate levels in the serum and liver decreased,whereas the levels of alanine aminotransferase(ALT)and aspartate aminotransferase(AST)in serum increased in ageing mice.Consistently,cell senescence,decreased glycogen levels and increased lipid deposition were found in the liver of aged mice,both glucokinase(GCK)and phosphoenolpyruvate carboxykinase(PCK)were down-regulated(n=10).Daily nitrate intake(0.5 mmol L^(-1))restored nitrate levels,decreased ALT and AST levels,and prevented cell senescence and structural and glucose and lipid metabolism degeneration in liver tissue both in D-galactose(D-gal)-induced ageing mice(n=10)and in natural aged mice(n=10).In conclusion,the present study demonstrated that the reduction of nitrate levels was correlated with liver degeneration in ageing individuals and that dietary supplement of nitrate could restore the nitrate levels in serum and the liver and prevent ageing-related liver degeneration. | Haifeng Wang Lei Hu Le Li Xiaoshan Wu Zhipeng Fan Chunmei Zhang Jinsong Wang Jidong Jia Songlin Wang | 2018 | Science China(Life Sciences)2018，61，1： | 5 |
| 13 | Molybdenum isotopic composition as a tracer for low-medium temperature hydrothermal ore-forming systems:A case study on the Dajiangping pyrite deposit,western Guangdong Province,China显示文摘Little is known about the range or controls on the molybdenum isotopic composition of low-medium temperature hydrothermal ore-forming systems.We present molybdenum isotope data from 12 hydrothermal syndepositional silicalite and carbonaceous slate samples from the Dajiangping pyrite deposit in western Guangdong Province,South China.The δ 97/95Mo values from Orebody III range from ?0.02‰ to 0.29‰,with an average of 0.18‰.In contrast,the composition values from Orebody IV display a larger variation from ?0.70‰ to 0.62‰.However,the five samples from the main ore bed all show strong negative values.This indicates that the significant variation in molybdenum isotopic composition supports different hydrothermal ore-forming metallogenesis and a metallogenic environment between the two orebodies.Orebody III is likely to have been deposited from submarine exhalative hydrothermal fluids under a relatively strong reducing environment and Orebody IV may have also been influenced by hydrothermal superimposition in a more oxidized disequilibrium condition.In addition,the δ 97/95Mo values of Orebody IV are clearly negative,together with the values increasing stratigraphically upward in the ore beds,suggesting that the metallogenic environment of Orebody IV is different from the open oceanic systems.There might be dynamic fractionation in this restricted environment.Therefore,the molybdenum isotope can be used as an effective tracer for the ore-forming fluid and metallogenic environment. | SONG ShiMing HU Kai WEN HanJie ZHANG YuXu LI Kuang FAN HaiFeng | 2011 | Chinese Science Bulletin2011，56，21： | 4 |

| 15 | Topographical changes of ground surface affected by the shelterbelt along the Tarim Desert Highway显示文摘To study the effects of sand protection project on modern aeolian landform, the types, distribution, and intensity of topographical changes of the ground surface affected by the shelterbelt along the Tarim Desert Highway were determined by measuring the deflation and deposition of sand surface in the Tazhong area located in the hinterland of the Taklimakan Desert. The results showed that (1) the newly-formed landform in sand protection systems is dominated by aeolian deposition including the small-scale Nabkha Dunes, the medium-scale sheet-like sand deposition and the large-scale ridge-like sand deposition. To some degree, aeolian deflation landform can also be formed in the open space in the shelterbelt. Furthermore, it is difficult for aeolian deflation landform to develop in a large scale in the interdunes. However, aeolian deflation landform can be developed in a large-scale on the windward slope of secondary dunes in longitudinal complex sand ridges; (2) on the windward side of the sand protection systems, both the morphology and strike of dwarf mobile dunes in the interdunes are changed by the sand-obstructing forest belts and the ridge-like sand deposition around it. The wind- ward slope of the ridge-like deposition around the sand-obstructing forest belt forms a stable ground surface. After being damaged by forward-moving dunes in a short period, the ground surface is re- covered gradually; (3) on the leeward side of the sand protection systems, aeolian deflations are formed widely. Particularly, the deflation depression is formed in the interdunes. In addition, the dunes in the region with highly topographic relief are cut flat by aeolian deflations; thereafter its relief of to- pography is reduced. The above analysis indicates that shelterbelts have obvious effects on the windward wind-sand flux in terms of dissipating energy and intercepting sand. With the recovery of wind velocity on the leeward side of the sand protection systems, the wind-sand flux gradually tends to be unsaturated; therefore the sand surface deflation is formed. | LI ShengYu LEI JiaQiang XU XinWen WANG HaiFeng FAN JingLong GU Feng QIU YongZhi XU Bo GONG Qing ZHENG Wei | 2008 | Chinese Science Bulletin2008，53，S2： | 4 |
| 16 | Structure and deformation measurements of shallow overburden during top coal caving longwall mining显示文摘Mining induced pressures are strong and overburden failure areas are large in top coal caving longwall mining, which constrains high production and safety mining. By employing the combination of the full view borehole photography technique and the seismic CT scanner technique, the deformation and failure of overlying strata of fully mechanized caving face in shallow coal seam were studied and the failure development of overburden was determined. Results show that the full view borehole photography can reveal the characteristics of strata, and the seismic CT scanner can reflect the characteristics of strata between the boreholes. The combined measurement technique can effectively determine the height of fractured and caved zones. The top end of the caved zone in Yangwangou coal mine employing the top coal caving longwall mining was at the depth of 171 m and fractured zone was at the depth of 106-110 m. The results provide a theoretic foundation for controlling the overburden strata in the shallow buried top coal caving panel. | Li Sheng Fan Chaojun Luo Mingkun Yang Zhenhua Lan Tianwei Zhang Haifeng | 2017 | International Journal of Mining Science and Technology2017，27，6： | 4 |
| 17 | Effect of the shelterbelt along the Tarim Desert Highway on air temperature and humidity显示文摘The temperature and humidity of the shelterbelt micro-climate on both horizontal and vertical scales in the extremely drought area were measured with multiple HOBO temperature and humidity automatic observation equipments in the hinterland of the Taklimakan Desert. The results show that the shelterbelt ecosystem of the desert highway plays typical micro-climate adjustment rolesin stabilizing surface air temperature and increasing air humidity, and so on. Solar radiation significantly affects both temperature and humidity of surface layers, and it has a positive correlation with the temperature but a negative correlation with the air humidity. When it is cloudy, the weather has a great impact on keeping temperature and humidity in the shelterbelt. The shelterbelt also significantly influences the environment, and the micro-climate in the belt has an obvious characteristic of cooling and humidification: compared with the original sand area, the temperature in the shelterbelt is always lower and the humidity is always higher. Moreover, the temperature range at the shelterbelt edge is greater than that in the sand area, but the humidity is always higher. Our conclusion is that the vertical-effect range of temperature of the shelterbelts is 4 -10 m, and the humidity range is 6 to 8 m; the horizontal-effect range of temperature is 16 m and the humidity range is about 24 m. | WANG HaiFeng LEI JiaQiang LI ShengYu FAN JingLong LI YingGang SUN ShuGuo CHANG Qing | 2008 | Chinese Science Bulletin2008，53，S2： | 4 |
| 18 | Mechanical and tribological performance of CoCrNiHf_(x)eutectic medium-entropy alloys显示文摘The excellent properties of the multi-principal element alloys(e.g.,the CoCrNi medium-entropy alloy)make them a perfect candidate for structure materials.Their low strength and poor wear-resistance,however,limit considerably their applications.In this study,a lamellar eutectic microstructure was introduced by addition of Hf into CoCrNi alloy to produce a series of CoCrNiHf_(x)(x=0.1,0.2,0.3 and 0.4)eutectic medium-entropy alloys.A homogeneous eutectic microstructure with an alternate array of the soft FCC solid-solution phase and the hard Laves phase was identified for the as-cast CoCrNiHf_(0.3)alloy.After an investigation of the microstructure,mechanical and tribological properties,it was found that the hardness(plasticity)increases(decreases)with the increasing volume fraction of the Laves phase and the CoCrNiHf_(0.3)eutectic alloy exhibits both good plasticity and high strength.The wear behavior is strongly dependent on the applied normal load.For a low normal load,its tribological behavior follows the Archard's equation and a higher hardness due to Hf addition can resist plastic deformation and abrasive wear.When the normal load is high enough,the hypoeutectic or hypereutectic alloy,which possessing either high strength or good ductility but not at the same time,exhibit a poor wear resistance.In comparison,the full eutectic CoCrNiHf_(0.3)alloy with a superior combination of strength and toughness shows the best wear performance,as it can significantly reduce fracture during wear. | Yin Du Xuhui Pei Zhaowu Tang Fan Zhang Qing Zhou Haifeng Wang Weimin Liu | 2021 | Journal of Materials Science & Technology2021，，31： | 4 |
| 19 | DID Code:A Bridge Connecting the Materials Genome Engineering Database w让h Inheritable Integrated Intelligent Manufacturing显示文摘A data identifier(DID)is an essential tag or label in all kinds of databases—particularly those related to integrated computational materials engineering(ICME),inheritable integrated intelligent manufacturing(I3M),and the Industrial Internet ofThings.With the guidance and quick acceleration of the developme nt of advanced materials,as envisioned by official documents worldwide,more investigations are required to construct relative numerical standards for material informatics.This work proposes a universal DID format consisting of a set of build chains,which aligns with the classical form of identifier in both international and national standards,such as ISO/IEC 29168-1:2000,GB/T 27766-2011,GA/T 543.2-2011,GM/T 0006-2012,GJB 7365-2011,SL 325-2014,SL 607-201&WS 363.2-2011,and QX/T 39-2005.Each build chain is made up of capital letters and numbers,with no symbols.Moreover,the total length of each build chain is not restricted,which follows the formation of the Universal Coded Character Set in the international standard of ISO/IEC 10646.Based on these rules,the proposed DID is flexible and convenient for extendi ng and sharing in and between various cloud-based platforms.Accordingly,classical two-dimensional(2D)codes,including the Hanxin Code,Lots Perception Matrix(LP)Code,Quick Response(Q.R)code,Grid Matrix(GM)code,and Data Matrix(DM)Code,can be constructed and precisely recognized and/or decoded by either smart phones or specific machines.By utilizing these 2D codes as the fingerprints of a set of data linked with cloud-based platforms,progress and updates in the composition-processing-structure-property-performance workflow process can be tracked spontaneously,paving a path to accelerate the discovery and manufacture of advanced materials and enhance research productivity,performance,and collaboration. | William Yi Wang Peixuan Li Deye Lin Bin Tang Jun Wang Quanmei Guan Qian Ye Haixing Dai Jun Gao Xiaoli Fan Hongchao Kou Haifeng Song Feng Zhou Jijun Ma Zi-Kui Liu Jinshan Li Weimin Liu | 2020 | Engineering2020，6，6： | 4 |
| 20 | Determination of total selenium in geological samples by HG-AFS after concentration with thiol cotton fiber显示文摘Standard reference material and different geological samples were dissolved by system A (the mixture of nitric and perchloric acids) and system B (mixture of nitric, perchloric and hydrofluoric acids), and total Se in all samples was measured by hydride-generation atomic fluorescence spectrometry (HG-AFS) after concentration with thiol cotton fiber (TCF). The analytical results obtained by the two digestion method are in good agreement (within the limit of errors) for most of the samples, particularly for those having recommended values. The Se concentrations determined by the two methods are of no difference, and the correlation coefficient is 0.9986; the relative standard deviation (RSD) for the determination of 0.04 μg/g Se is 10.2%. The recovery rates of systems A and B by the stan- dard-addition method were 96%–106% and 99%–104%, respectively. | FAN Haifeng WEN Hanjie HU Ruizhong CHANG Bin | 2008 | Chinese Journal Of Geochemistry2008，27，1： | 3 |
