| 1 | Technical framework for Internetware: An architecture centric approach显示文摘Being a new software paradigm evolved by the Internet, Internetware brings many challenges to the traditional software methods and techniques. Sponsored by the national basic research program (973), researchers in China have developed an architecture centric technical framework for the definition, incarnation and engineering of Internetware. First of all, a software model for Internetware is defined for what to be, including that Internetware entities should be packaged as components, behaving as agents, interoperating as services, collaborating in a structured and on demand manner, etc. Secondly, a middleware for Internetware is designed and implemented for how to be, including that Internetware entities are incarnated by runtime containers, structured collaborations are enabled by runtime software architecture, Internetware can be managed in a reflective and autonomic manner, etc. Thirdly, an engineering methodology for Internetware is proposed for how to do, including the way to develop Internetware entities and their collaborations by transforming and refining a set of software architectures which cover all the phases of software lifecycle, the way to identify and organize the disordered software assets by domain modeling, etc. | YANG FuQing1,2, Lü Jian3,4 & MEI Hong1,2 1 Key Laboratory of High Confidence Software Technologies (Peking University), Ministry of Education, Beijing 100871, China 2 School of Electronics Engineering and Computer Science, Peking University, Beijing 100871, China 3 State Key Laboratory for Novel Software Technology, Nanjing 210093, China 4 Department of Computer Science and Technology, Nanjing University, Nanjing 210093, China | 2008 | Science in China(Series F)2008，51，6： | 33 |
| 2 | Sorption of Eu(Ⅲ) on GMZ bentonite in the absence/presence of humic acid studied by batch and XAFS techniques显示文摘Bentonite has been extensively studied because of its strong sorption ability and low permeability.In this work,the Na-bentonite from Gaomiaozi County (China) has been characterized by XRD,FTIR and acid-base titration.The sorption of Eu(III) on Na-bentonite in the absence/presence of humic acid (HA) was studied at T = 25 ± 2 °C and in 0.01 mol/L NaClO4 solution.The effects of pH,HA,contact time and initial Eu(III) concentrations were also investigated.The results indicate that the sorption of Eu(III) on Na-bentonite was dependent on pH values.The presence of HA had little effect on Eu(III) sorption at low pH values,but decreased Eu(III) sorption at high pH values.X-ray absorption fine structure spectroscopy (XAFS) was applied to characterize the local structural environment of the adsorbed Eu(III) on bare Na-bentonite and HA-bentonite hybrids.The re- sults indicate that Eu(III) was bound to O atoms at a distance of about 2.39 at pH 4.15.The results are crucial for the evalua- tion of the sorption and migration of other trivalent lanthanides and actinides in bentonite as backfill materials. | HU Jun1,2,XIE Zhi3,HE Bo3,SHENG GuoDong1,CHEN ChangLun1,LI JiaXing1,CHEN YiXue2 & WANG XiangKe1 1Key Laboratory of Novel Thin Film Solar Cells Institute of Plasma Physics,Chinese Academy of Sciences,Hefei 230031,China 2School of Nuclear Science and Engineering,North China Electric Power University,Beijing 102206,China 3National Synchrotron Radiation Laboratory,University of Science & Technology of China,Hefei 230029,China | 2010 | Science China Chemistry2010，53，6： | 12 |
| 3 | Investigation of radionuclide~(63)Ni(Ⅱ) sequestration mechanisms on mordenite by batch and EXAFS spectroscopy study显示文摘The sorption behavior and microscopic sequestration mechanisms of radionuclide 63Ni(II) on mordenite as a function of aging time,ionic strength,initial 63Ni(Ⅱ) concentrations,solid content and coexistent electrolyte ions were investigated by the com-bination of batch and EXAFS techniques.Macroscopic experiment results show that the sorption of 63Ni(Ⅱ) is dependent on ionic strength at pH<7,and independent of ionic strength at pH>7.The sorption percentage of 63Ni(Ⅱ) on mordenite increases with increasing solid content,while the sorption capacity decreases as solid content increases.The presence of different elec-trolyte ions can enhance or inhibit the sorption of Ni(II) on mordenite in various degrees.EXAFS analysis results of the sam-ples under three different ionic strengths suggest that the retained 63Ni(Ⅱ) in these samples exists in an octahedral environment with six water ligands.In the initial period of rapid uptake,the sorption of 63Ni(Ⅱ) is dominated by the formation of in-ner-sphere surface complexes.As aging time increases,63Ni(Ⅱ) sequestration behavior tends to be mainly controlled by the formation of Ni phyllosilicate co-precipitates and/or Ni(OH)2(s) precipitates.Results for the second shell fit of the sample pre-pared at an initial 63Ni(Ⅱ) concentration of 100 mg/L indicate the possible formation of Ni polynuclear surface complexes.Both the macroscopic sorption data and the molecular level evidence of 63Ni(Ⅱ) surface speciation at the mordenite/water in-terfaces should be factored into better predictions of the mobility and bioavailability of 63Ni(Ⅱ) in environment mediums. | YANG ShiTong,SHENG GuoDong,GUO ZhiQiang,TAN XiaoLi,XU JinZhang & WANG XiangKe Key Laboratory of Novel Thin Film Solar Cells,Institute of Plasma Physics,Chinese Academy of Sciences,Hefei 230031,China | 2012 | Science China Chemistry2012，55，4： | 5 |

| 5 | Efficient expression of codon-adapted human acetaldehyde dehydrogenase 2 cDNA with 6×His tag in Pichia pastoris显示文摘Human mitochondrial acetaldehyde dehydrogenase 2 (ALDH2) catalyzes the oxidation of acetaldehyde to acetic acid. Therefore, ALDH2 has therapeutic potential in detoxification of acetaldehyde. Further-more, ALDH2 catalyzes nitroglycerin to nitrate and 1, 2-glyceryldinitrate during therapy for angina pectoris, myocardial infarction, and heart failure. Large quantities of ALDH2 will be needed for potential clinical practice. In this study, Pichia pastoris was used as a platform for expression of human ALDH2. Based on the ALDH2*1 cDNA sequence, we designed ALDH2 cDNA by choosing the P. pastoris preferred codons and by decreasing the G + C content level. The sequence was synthesized using the overlap extension PCR method. The cDNA and 6×His tags were subcloned into the plasmid pPIC9K. The recombinant protein was expressed in P. pastoris GS115 and purified using Ni2+-Sepharose affinity chromatography. The amount of secreted protein in the culture was 80 mg/L in shake-flask cultivation and 260 mg/L in high-density bioreactor fermentation. Secreted ALDH2 was easily purified from the culture supernatant by using Ni2+-Sepharose affinity chromatography. After purification of the fermentation supernatant, the enzyme had a specific activity of 1.2 U/mg protein. The yield was about 16 mg/L in a shake flask culture of P. pastoris GS115 which contained the original human ALDH2*1 cDNA. | ZHAO YuFeng1,2, LEI MingKe2, WU YuanXin2, ZHANG ZiSheng3 & WANG CunWen2 1 State key Laboratory of Agricultural Microbiology, College of Life Science and Technology, Huazhong Agriculture University, Wuhan 430070, China 2 Key Laboratory for Green Chemical Processes of the Ministry of Education, Hubei Key Lab of Novel Reactor & Green Chemical Technology, School of Chemical Engineering and Pharmacy, Wuhan Institute of Technology, Wuhan 430074, China 3 Department of Chemical Engineering, University of Ottawa, Ottawa, Canada K1N 6N5 | 2009 | Science China(Life Sciences)2009，52，10： | 3 |
| 6 | Structure and property of metal melt Ⅰ:The number of residual bonds after solid-liquid phase changes显示文摘Based on the mechanism of metal solid-liquid phase change and the theory of liquid metal's micro-inhomogeneity,a physical model is established between latent heats of fusion and vaporization and the numbers of residual bonds and short-range ordered atoms at the melting point inside a metal melt.Meanwhile,the mathematical derivation and proof are also offered.This model produces the numbers of residual bonds and short-range ordered atoms after the solid-liquid phase change only by using basic parameters and thermophysical properties of the crystal structure.Therefore,it presents a more effective way to analyze the melt's structural information.By using this model,this study calculates the numbers of residual bonds and short-range ordered atoms in Al and Ni melts.The calculated results are consistent with the experimental results.Simultaneously,this study discusses the atomic number's influence on the numbers of residual bonds and short-range ordered atoms in the melts within the first(ⅠA) and second main group(ⅡA) elements. | MI GuangBao1,2,LI PeiJie1,2 & HE LiangJu1 1 National Center of Novel Materials for International Research,Tsinghua University,Beijing 100084,China 2 Department of Mechanical Engineering,Tsinghua University,Beijing 100084,China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，9： | 3 |
| 7 | Structure and property of metal melt Ⅱ—Evolution of atomic clusters in the not high temperature range above liquidus显示文摘Based on the theory of micro-inhomogeneity of liquid metal,a calculation model is established for the quantitative description of the structural information of metal melts.Only by thermophysical property parameters and basic structural parameters of solid metal,can this model produce the main information of melt structure,including the relative concentration of active atoms,size of atomic clusters and number of short-range order atoms.Based on this model,the main structural information of Al and Ni melts in the not high range above the liquidus is calculated,with results in good agreement with experimental values.Besides,analyzed is the influence of superheating temperature and atomic number on the melt structural information of the first (IA) and second main group (IIA) elements.With temperature increasing,melt structural information regularly changes for both IA and IIA elements.With the atomic number increasing,melt structural information of IA elements changes regularly,for the crystal structures of the IA elements are all of bcc lattice type.However,no notable regular change of melt structural information for IIA elements has been found,mainly because the lattice type of IIA elements is of hcp-fcc-bcc transition.The present work presents an effective way for better understanding metal melt structure and for forecasting the change of the physical property of metal melts. | MI GuangBao1,2*,LI PeiJie1,2 & HE LiangJu1 1 National Center of Novel Materials for International Research,Tsinghua University,Beijing 100084,China 2 Key Laboratory for Advanced Materials Processing Technology Ministry of Education,Department of Mechanical Engineering,Tsinghua University,Beijing 100084,China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，10： | 3 |
| 8 | SiC fiber with low electrical resistivity and oxygen content显示文摘A new SiC fiber was prepared by the pyrolysis of polycarbosilane(PCS) fiber cured with unsaturated hydrocarbons.The fiber,with oxygen content of 4-6 wt%,offers high tensile strength of 2.5-2.8 GPa.The electrical resistivity of the fiber is only about 0.5 Ω·cm,much lower than general SiC fiber obtained from traditional air curing process.Degradation of mechanical property in argon and air at high temperature is retarded by 200-300℃ with respect to the Nicalon NL-202 fiber.The low electrical resistivity of the fiber exhibits excellent thermal stability,it almost remains 0.4-0.8 Ω·cm after thermal exposure test from the room temperature to 1600℃ in argon.The low electrical resistivity mainly attribute to an excess carbon layer which is about 50 nm in the circular outer part. | WANG DeYin,MAO XianHe,SONG YongCai & WANG YingDe State Key Lab of Novel Ceramic Fibers and Composites,National University of Defense Technology,Changsha 410073,China | 2010 | Science China(Technological Sciences)2010，53，4： | 3 |
