2Processing effects on the magnetic and mechanical properties of FeCoNiAl_(0.2)Si_(0.2) high entropy alloy显示文摘High entropy alloys with the composition of FeCoNiAl0.2Si0.2 were prepared by arc melting and induction melting, denoted by A1 and A2, respectively. The samples prepared by these two techniques have a face-centered cubic (FCC) phase structure and a typical dendrite morphology. The tensile yield strength and maximum strength of A2 samples are about 280 and 632 MPa, respectively. Moreover, the elongation can reach 41.7%. These two alloys prepared by the different methods possess the similar magnetic properties. The saturation magnetization and coercivity can reach 1.151 T and 1400 A/m for Al samples and 1.015 T and 1431 A/m for A2 samples, respectively. Phases in A2 samples do not change, which are heat treated at different temperatures, then quenched in water. Only the sample, which is heat treated at 600C for 3h and then furnace cooled, has a new phase precipitated. Besides, the coercivity decreases obviously at this temperature. Cold rolling and the subsequent heat treatment cannot improve the magnetic properties effectively. However, cold rolling plays an important role in improving the strength.Ting-ting Zuo Song-bo Ren Peter K. Liaw Yong Zhang 2013International Journal of Minerals,Metallurgy and Materials2013,20,6:12

5锂离子电池加速老化温度应力的滥用边界显示文摘为了探寻加速老化合适的温度应力区间,设计了温度变化为30~80℃的循环老化实验,通过电池外特性分析与解体分析等手段对锂离子电池老化机理进行了探讨。结果表明:老化速率随着温度的升高先降低、再升高。基于老化速率,将温度工况分为常温(30~56℃)、中高温(56~68℃)、高温(68~80℃)3个区域。在常温区域,老化速率随着温度升高而降低,锂离子电池存在析锂现象;在高温区域,电池电极出现活性物质脱落现象,导致锂离子电池容量的衰减;而在中高温区域,通过活化能计算判断电池老化机理为固体电解质界面膜(SEI)的生长。该研究成果可以指导加速老化实验的设计,也为寿命预测模型的开发提供参考。吴正国 张剑波 李哲 LIAW Bor Yann 2018汽车安全与节能学报2018,9,1:10

8Hepatocyte growth factor gene therapy prevents radiation-induced liver damage显示文摘AIM: To transfer human HGF gene into the liver of rats by direct electroporation as a means to prevent radiationinduced liver damage.METHODS: Rat whole liver irradiation model was accomplished by intra-operative approach. HGF plasmid was injected into liver and transferred by electroporation using a pulse generator. Control rats (n = 8) received electrogene therapy (EGT) vehicle plasmid and another 8rats received HGF-EGT 100 μg 48 h before WLIR.Expression of HGF in liver was examined by RT-PCR and ELISA methods. Apoptosis was determined by TUNEL assay. Histopathology was evaluated 10 wk after whole liver irradiation.RESULTS: Marked decrease of apoptotic cells and downregulation of transforming growth factor-beta 1 (TGF-β1)mRNA were observed in the HGF-EGT group 2 d after liver irradiation compared to control animals. Less evidence of radiation-induced liver damage was observed morphologically in liver specimen 10 wk after liver irradiation and longer median survival time was observed from HGF-EGT group (14 wk) compared to control rats (5 wk). (P = 0.031).CONCLUSION: For the first time it has been demonstrated that HGF-EGT would prevent liver from radiation-induced liver damage by preventing apoptosis and down-regulation of TGF-β1.Chau-Hua Chi I-Li Liu Wei-Yu Lo Bor-Song Liaw Yu-Shan Wang Kwan-Hwa Chi 2005World Journal of Gastroenterology2005,11,10:6

10Glutamine-supplemented total parenteral nutrition attenuates plasma interleukin-6 in surgical patients with lower disease severity显示文摘AIM: To evaluate whether the effect of Gln dipeptideenriched total parenteral nutrition (TPN) on postoperative cytokine alteration depended on the disease severity of surgical patients.METHODS: Forty-eight patients with major abdominal surgery were allocated to two groups to receive isonitrogenous (0.228 g nitrogen/kg per d) and isocaloric(30 kcal/kg per d) TPN for 6 d. Control group (Conv)using conventional TPN solution received 1.5 g amino adds/kg per day, whereas the test group received 0.972 g amino acids/kg per day and 0.417 g L-alanyl-L-glutamine(Ala-Gln)/kg per day. Blood samples were collected on d 1 and d 6 postoperatively for plasma interleukin (IL)-2,IL-6, IL-8, and interferon (IFN)-γ analysis.RESULTS: Plasma IL-2 and IFN-γ were not detectable.IL-6 concentrations were significantly lower on the 6th postoperative day in the Ala-Gln group than those in the Conv group in patients with APACHE Ⅱ≤6, whereas no difference was noted in patients with APACHE Ⅱ>6. There was no difference in IL-8 levels between the two groups.No difference in cumulative nitrogen balance was observed on d 2-5 after the operation between the two groups(Ala-Gln -3.2±1.6 g vs Conv -6.5±2.7 g). A significant inverse correlation was noted between plasma IL-6 levels and cumulative nitrogen balance postoperatively in the Ala-Gln group, whereas no such correlation was observed in the Conv group.CONCLUSION: TPN supplemented with Gln dipeptide had no effect on plasma IL-8 levels after surgery. However,Gln supplementation had a beneficial effect on decreasing systemic IL-6 production after surgery in patients with low admission illness severity, and lower plasma IL-6 may improve nitrogen balance in patients with abdominal surgery when Gln was administered.Ming-Tsan Lin Sung-Pao Kung Sung-Ling Yeh Koung-Yi Liaw Ming-Yang Wang Ming-Liang Kuo Po-Houng Lee Wei-Jao Chen 2005World Journal of Gastroenterology2005,11,39:5

14Preternatural Hexagonal High-Entropy Alloys: A Review显示文摘Recently,various topics on high-entropy alloys have been reported and great amounts of excellent properties have been investigated,including high strength,great corrosion resistance,great thermal stability,good fatigue and fracture properties,etc.Among all these research activities,high-entropy alloys tend to form face-centered-cubic(FCC)or body-centeredcubic(BCC)solid solutions due to their high-entropy stabilization effect,while the hexagonal structures are rarely reported.Up to now,the reported hexagonal high-entropy alloys are mainly composed of rare-earth elements and transitional elements.Their phase transformation and magnetic properties have also aroused wide concern.This study summarizes the above results and provides the forecast to the future.Rui-Xuan Li Jun-Wei Qiao Peter K.

16A trend based investment decision approach using clustering and heuristic algorithm显示文摘This paper proposes a stock price trend clustering and trend investment decision model by using a genetic algorithm to search for optimal solutions and the best investment strategies for different stock price trends.The new price trend clustering model identifies three types of stock price movements:uptrends,sideways trends,and downtrends.Unfortunately,trends discovered through stock price movements or technical indicator graphs are typically subjective and unquantifiable.This paper takes daily stock prices and trading volume data from the China Shanghai Stock Exchange Composite Index(SSECI)from January 2,1997 to August31,2012,to examine the performance of the proposed trend clustering model.The proposed model is also compared to other popular stock market investment strategies to verify its validity.Research result shows that the proposed trend clustering model correctly identifies three different trends in the stock market.Furthermore,the trend investment strategy model developed by using genetic algorithm methodology performs better than other investment strategies,namely,Granville’s rule,the KD indicator strategy,the buys and holds strategy,and GMA rules,in both bull and bear market periods.Research results prove the proposed new model to be a stable and valid investment strategy.WU ChungMin CHOU ShengChun LIAW HorngTwu 2014Science China(Information Sciences)2014,57,9:4
17Design of near-α Ti alloys via a cluster formula approach and their high-temperature oxidation resistance显示文摘The multi-component composition characteristics of high-temperature near-α Ti alloys were investigated in the present work by means of a cluster formula approach. The uniform cluster formula [CN12 cluster](glue atom)3 for the hexagonal close-packed α solid solution was first obtained based on the Friedel oscillation theory, with a total atom number in the formula of Z = 16. Then it was analyzed that the Z values in the cluster composition formulas of typical near-α Ti alloys are within the range of Z = 16.0016.30, being perfectly consistent with the ideal Z = 16. Based on it, a series of new alloys with Z = 16 and with Nb/Ta substitution for Mo in Ti1100 alloy were designed, suction-cast into φ 6 mm rods, and then heat-treated with solid solution and aging. It was found that the alloy with co-addition of Mo, Ta and Nb has a high strength and good ductility at both room and high temperatures. More importantly, the additions of Nb and Ta can contribute to the formation of continuous and compact Al2O3 scales, resulting in an obvious improvement of oxidation resistances at both 923 K and 1073 K. The effects of Mo, Ta and Nb on the oxidation behaviors of the designed alloys at 1073 K were further discussed.Beibei Jiang Donghui Wen Qing Wang Jinda Che Chuang Dong Peter K.
