| 1 | Ultrafast epitaxial growth of metre-sized single-crystal graphene on industrial Cu foil显示文摘A foundation of the modern technology that uses single-crystal silicon has been the growth of highquality single-crystal Si ingots with diameters up to 12 inches or larger. For many applications of graphene, large-area high-quality(ideally of single-crystal) material will be enabling. Since the first growth on copper foil a decade ago, inch-sized single-crystal graphene has been achieved. We present here the growth, in 20 min, of a graphene film of(5 ×50) cm^2 dimension with >99% ultra-highly oriented grains.This growth was achieved by:(1) synthesis of metre-sized single-crystal Cu(1 1 1) foil as substrate;(2)epitaxial growth of graphene islands on the Cu(1 1 1) surface;(3) seamless merging of such graphene islands into a graphene film with high single crystallinity and(4) the ultrafast growth of graphene film.These achievements were realized by a temperature-gradient-driven annealing technique to produce single-crystal Cu(1 1 1) from industrial polycrystalline Cu foil and the marvellous effects of a continuous oxygen supply from an adjacent oxide. The as-synthesized graphene film, with very few misoriented grains(if any), has a mobility up to ~23,000 cm^2 V^(-1)s^(-1)at 4 K and room temperature sheet resistance of ~230 Ω/□. It is very likely that this approach can be scaled up to achieve exceptionally large and high-quality graphene films with single crystallinity, and thus realize various industrial-level applications at a low cost. | Xiaozhi Xu Zhihong Zhang Jichen Dong Ding Yi Jingjing Niu Muhong Wu Li Lin Rongkang Yin Mingqiang Li Jingyuan Zhou Shaoxin Wang Junliang Sun Xiaojie Duan Peng Gao Ying Jiang Xiaosong Wu Hailin Peng Rodney S.

| 2 | Blockade of cholecystokinin-2 receptor and cyclooxygenase-2 synergistically induces cell apoptosis, and inhibits the proliferation of human gastric cancer cells in vitro显示文摘Gastrin and cyclooxygenase-2(COX-2) playimportant roles in the carcinogenesis and progression ofgastric cancer.However,it remains unknown whether the combination of cholecystokinin-2(CCK-2) receptor antagonist plus COX-2 inhibitor exerts synergistic anti-tumor effects on human gastric cancer.Here,we demonstrated that the combination of AG-041R(a CCK-2 receptor antagonist) plus NS-398(a selective COX-2 inhibitor) treatment had synergistic effects on proliferation inhibition,apoptosis induction,down-regulation of Bcl-2 and up-regulation of Bax expression in MKN-45 cells.These results indicate that simultaneous targeting of CCK-2 receptor and COX-2 may inhibit gastric cancer development more effectively than targeting either molecule alone.(C)2008 Elsevier Ireland Ltd.All rights reserved. | Sun, W.

| 4 | DISLOCATION DISSOCIATIONS AND FAULTENERGIES IN Ni_3Al ALLOYS DOPED WITH PALLADIUM显示文摘Dislocation structures in polycrystalline Ni 3Al alloy doped with palladium deformed at room temperature have been investigated by transmission electron microscopy. The structure consists mainly of dislocations dissociated into a /2〈011〉 super partials bounding an anti phase boundary (APB). Dislocations dissociated into a /3〈112〉 super Shockley partials bounding a superlattice intrinsic stacking fault (SISF) are also common debris. The majority of the SISFs are truncated loops, i.e. the partials bounding the SISF are of similar Burgers vector. These faulted loops are generated from APB coupled dislocations, according to a mechanism for formation of SISFs proposed by Suzuki et al , and recently modified by Chiba et al . The APB energies for {111} and {010} slip planes are measured to be 144±20 mJ/m 2 and 102±11 mJ/m 2 respectively, and the SISF energy has been estimated to be 12 mJ/m 2 in this alloy. It is concluded that the dislocation structure in Ni 74.5 Pd 2Al 23.5 alloy deformed at room temperature is similar to that in binary Ni 3Al, and the difference in fault energies between these two alloys is small. Thus, it seems unlikely that the enhancement of ductility of Ni 74.5 Pd 2Al 23.5 results from only such a small decrease of the ordering energy of the alloy. SISF bounding dislocations also have no apparent influence on the ductilization of Ni 74.5 Pd 2Al 23.5 alloy. | J. Sun *# , C. S. Lee # and J. K. L.

| 5 | Boundary of Cretaceous and Paleogene continental deposits in Zeya-Bureya Basin,Amur(Heilongjiang)River region显示文摘It was conducted the comparison of palynological assemblages of the Middle Tsagayan,Upper Tsagayan subformations,Furao and Wuyun formations from Zeya-Bureya Basin of Amur (Heilongjiang) River region with assemblages obtained from the marine deposits of Northeast Russia,Sakhalin,Kuril,and Hokkaido Islands,dated by ammonites,foraminifers and other invertebrates. Based on detail correlation,the geological age of the terrestrial beds was defined. The guide fossils are recognized Marsypiletes cretacea,Tricolpites variexi- nus,Aquilapollenites conatus,A. stelkii,A. rombicus,Integricorpus bellum,Pseudointegricorpus clarireticula- tus,Triprojectus amoenus,Orbiculapollis lucidus,Wodehouseia aspera,Quercoidites minor,which had last oc- currence in the late Maastrichtian. The Danian palynofloras usually are dominated by Triatriopollenites plicoides and T. confusus. The species Anacolosidites subtrudens,Aquilapollenites proceros,A. spinulosus have last occurrence in the Danian. The K-T (K-Pg) boundary in the terrestrial deposits is defined in the base of the Upper Tsagayan Subformation and the base of the lower part of the Wuyun Formation. The latter is represented by aleuropelite to fine-grained sandstones. The change of taxonomical composition of palynospectra in similar environments could be determined by real change of flora at the Mesozoic and Cenozoic boundary,but not by changes of lithological facies or depositional environment,generally. | Valentina S.

| 6 | Seasonal Changes in Food Uptake by the Sea Cucumber Apostichopus japonicus in a Farm Pond: Evidence from C and N Stable Isotopes显示文摘This study investigated the seasonal changes in carbon (C) and nitrogen (N) stable isotope values of several typical food sources of Apostichopus japonicus in a farm pond, including particulate organic matter (POM), macroalgae, benthic microalgae and animals such as nematode and copepod. The stable isotope technique was used to quantify relative contributions of various sources to the food uptake by A. japonicus. The results showed that significant changes occurred in the C and N stable isotope values of sea cucumber food sources due to the seasonality of micro-or macroalgae prosperity and the fluctuation of environmental conditions. The sea cucumber A. japonicus exhibited corresponding alterations in feeding strategy in response to the changes in food conditions. Calculation with a stable isotope mixing model showed that macroalgae was the principal food source for A. japonicus throughout the 1-yr investigation, with the relative contribution averaging 28.1% - 63.2%. The relative contributions of other food sources such as copepod and nematode, POM, benthic microalgae to the total food uptake by sea cucumber averaged 22.6% - 39.1%, 6.3% - 22.2%, 2.8% - 6.5%, and 2.8% - 4.2%, respectively. Together these results indicated that the seasonal changes in food sources led to the obvious temporal differences in the relative contribution of various food sources utilized by A. japonicus. Such findings provide the basic scientific information for improving the aquaculture techniques of A. japonicus, particularly for optimizing the food environment of A. japonicus culture in farm ponds. | SUN Zhenlong GAO Qinfeng DONG Shuanglin Paul K.

| 12 | Thermodynamic analysis of mixed and dry reforming of methane for solar thermal applications显示文摘Thermodynamic analysis of the reforming of methane with carbon dioxide alone ('dry reforming') and with carbon dioxide and steam together ('mixed reforming') is performed as part of a project which investigates the suitability of these endothermic reactions for the storage of solar thermal energy. The Gibbs free energy minimization method was employed to identify thermodynamically optimal operating conditions for dry reforming as well as mixed reforming with a desired H2/CO molar ratio of 2. The non-stoichiometric equilibrium model was developed using FactSage software to conduct the thermodynamic calculations for carbon formation, H2/CO ratio, CH4 conversion and H2 yield as a function of reaction temperature, pressure and reactant molar ratios. Thermodynamic calculations demonstrate that in the mixed reforming process, optimal operating conditions in a carbon-free zone are under H2O/CH4 /CO2 =1.0/1.0/0.5, p = 1 to 10 bar and T = 800 to 850℃ for the production of syngas with a H2 /CO molar ratio of 2. Under the optimal conditions, the maximum H2 yield of 88.0% is achieved at 1 bar and 850℃ with a maximum CH4 conversion of 99.3%. In the dry reforming process, a carbon formation regime is always present at a CO2/CH4 molar ratio of 1 for T = 700 1000℃ and p = 1-30 bar, whereas a carbon-free regime can be obtained at a CO2/CH4 molar ratio greater than 1.5 and T≥800℃. | Y.

| 14 | Localized CO_2 laser bonding process for MEMS packaging显示文摘The packaging poses a critical challenge for commercialization of MEMS products. Major problems with the packaging process include degraded reliability caused by the excess stress due to thermal mismatch and altered performance of the MEMS device after packaging caused by thermal exposure. The localized laser bonding technique for ceramic MEMS packaging to address above-mentioned challenges was investigated. A continuous wave CO2 laser was used to locally heat sealing material for ceramic MEMS package lid to substrate bonding. To determine the laser power density and scanning speed, finite element analysis thermal models were constructed to simulate the localized laser bonding process. Further, the effect of external pressure at sealing ring on the bonding formation was studied. Pull testing results show that the scanning speed and external pressure have significant influence on the pull strength at the bonding interface. Cross-sectional microscopy of the bonding interface indicates that the packages bonded with relatively low scanning speed and external pressure conditions have higher bonding quality. This research demonstrates the potential of localized laser bonding process for ceramic MEMS packaging. | SUN Li A. P. MALSHE S. CUNNINGHAM A. MORRIS | 2006 | 中国有色金属学会会刊:英文版2006,16,B02: | 4 |
| 15 | Laser Repair of Steam Turbine Blades(Invited Paper)显示文摘Reliable and efficient power generation is a major global issue due to both political and environmental concerns.Nevertheless many critical components,particularly the blades of the low pressure(LP) side of power generating steam turbines,are subjected to failure due to severe erosion at the leading edges.Since taking machines off-line for maintenance and removal of damaged blade for repair is extremely expensive,increasing the service life of these critical components can offer significant economic and political benefits.Conventional techniques to increase service life include brazing of an erosion shield at the leading edge of the turbine blades,open arc hardfacing,and cladding with erosion resistant materials using gas tungsten,manual metal or plasma transferred arc welding.We have been investigating for the past eight years the potential of laser cladding to deposit a high quality and erosion resistant protection shield on the leading edge of LP blades.Laser cladding offers unique advantages over the conventional techniques.The project to-date has demonstrated the feasibility of in-situ repair of turbine blades in trials conducted at a power station using a fibre delivered Laserline diode laser and a robot.A company(Hardwear Pty.Ltd.) has been established to commercialise the technology and has delivered two commercial contracts. | M.

| 16 | Preventing abnormal NF-κB activation and autoimmunity by Otub1-mediated p100 stabilization显示文摘NF-κB, a family of transcription factors regulating diverse biological processes including immune responses, is activated by canonical and noncanonical pathways based on degradation of IκBα and processing of the IκB-like protein p100, respectively. Although p100 responds to noncanonical NF-κB stimuli for processing, it does not undergo degradation, but rather becomes accumulated, along with canonical NF-κB activation. We show here that the stability of p100 is tightly controlled by a deubiquitinase, Otub1. Otub1 deficiency not only promotes signal-induced p100 processing and noncanonical NF-κB activation but also causes steady-state p100 degradation, leading to aberrant NF-κB activation in the canonical pathway. B-cell-conditional deletion of Otub1 results in B-cell hyperplasia, antibody hyper-production, and lupus-like autoimmunity. Otub1-deficient B cells display aberrantly activated phenotypes and overproduce the cytokine IL-6, contributing to autoimmunity induction. Thus, maintenance of p100 stability by Otub1 serves as an unusual mechanism of NF-κB regulation that prevents autoimmunity. | Yanchuan Li Jin-Young Yang Xiaoping Xie Zuliang Jie Lingyun Zhang Jianhong Shi Daniel Lin Meidi Gu Xiaofei Zhou Haiyan S.

In this study, we investigated the use of a composite of freeze dried V_2O_5·nH_2O nanosheets and multi-walled carbon nanotube(MWCNT) as a negative electrode material for SIBs. Cyclic voltammetry(CV) results indicated that a reversible sodium-ion insertion/deinsertion into the composite electrode can be obtained in the potential window of 0.1–2.5 V vs. Na^+/Na. The composite electrodes delivered sodium storage capacities of 140 and 45 m Ah g^(-1) under applied current densities of 20 and 100 m A g^(-1), respectively. The pause test during constant current measurement showed a raise in the open circuit potential(OCP) of about 0.46 V, and a charge capacity loss of ~10%. These values are comparable with those reported for hard carbon electrodes. For comparison, electrodes of freeze dried V_2O_5·nH_2O nanosheets were prepared and tested for SIBs application. The results showed that the MWCNT plays a significant role in the electrochemical performance of the composite material. | Ahmed S.

| 20 | Modification and characterization of fibers of three sandy willow shrub species显示文摘Periploca sepium, Salix psammophila and Tamarix spp. make up an important part of the local vegetation in the sandland of China. This paper described a novel method on modification of the three shrub fibers as oil sorbents. Natural and modified fibers were chemically studied by non-destructive methods, infrared spectroscopy (IR) and cross-polarization nuclear magnetic resonance (CP-MAS 13C-NMR). The results show that during the reaction with acetic anhydride under mild conditions, the use of N-bromoscciniamide (NBS) catalyst resulted in a high weight percent gain (WPG). The acetylation of P. sepium fiber gave rise to the highest WPG (20.0%) compared with S. psammophila and Tamarix spp. fiber. IR and CP-MAS 13C-NMR analysis elaborates the chemical features of natural and acetylated willow fiber in detail. | Sun Xiao-feng Xiao Bin Mark S.
