| 1 | Reaction thermodynamics and kinetics on in situ Al_2O_3/Cu composites显示文摘The preferred internal oxidation of aluminum in Cu Al alloy was used to obtain in situ Al 2O 3/Cu composites. The reinforcement particles were mainly γ Al 2O 3, some θ Al 2O 3 and a little α Al 2O 3. Thermodynamics analyses show that the chemical reactions are 3Cu 2O+2Al=6Cu+Al 2O 3 or 3CuO+2Al=3Cu+Al 2O 3. A related equilibrium diagram was drawn. The experiments and investigation show that the formation rate of Al 2O 3 was controlled by the diffusion of oxygen in matrix. | Li Guobin(李国彬) 1, Wu Jianjun(武建军) 1, Guo Quanmei(郭全梅) 2, Jiang Yanfei(姜延飞) 1, Shen Yutian(申玉田) 1, Lei Tingquan(雷廷权) 2 1.

| 3 | An anti-freezing biomineral hydrogel of high strain sensitivity for artificial skin applications显示文摘Mineral hydrogels have caught a lot of attention for their strong competency as artificial skin-like materials.Nonetheless,it remains a great difficulty in fulfilling in one hydrogel system a range of key functionalities that are needed for practical artificial skin applications,i.e.,to be biocompatible,strain-sensitive,ion-conductive,elastic and robust,anti-swelling,and anti-freezing.Here we present a such type of versatile hydrogel that is not only capable to deliver all the above-mentioned key functionalities but also highly stable.This novel hydrogel is constructed by introducing a gelatinous and amorphous multi-ionic biomineral(denoted as Mg-ACCP,containing Mg^(2+),Ca^(2+),CO_(3)^(2−),and PO_(4)^(3−))into the network of biocompatible polyvinyl alcohol(PVA)and sodium alginate(SA).The presence of Mg^(2+)and PO_(4)^(3−)in this hydrogel helps prohibit the crystallization of the biominerals,leading to significantly improved stability.The hydrogel thus obtained delivers excellent mechanical performance due to the chelation between the mineral ions and the organic matrix,and high sensitivity even to subtle pressure and strain applied,such as slight finger bending and gentle tapping.Furthermore,the novel hydrogel features high ionic conductivity,high resistance to swelling,and extraordinary anti-freezing property,holding great promise for applications in different practical scenarios,particularly in aqueous or cold environments. | Junda Shen Peng Du Binbin Zhou Guobin Zhang Xinxue Tang Jie Pan Bo Li Jingyang Zhang Jian Lu Yang Yang Li | 2022 | Nano Research2022，15，7： | 1 |
| 4 | TENSILE PROPERTIES AND INTERFACIAL FEATURE OF SiC COATED C/Al COMPOSITE WIRES UNDER ISOTHERMAL HEAT TREATMENT显示文摘The effect of different regimes of heat treatment on the tensile strength of SiC coatedcomposite of C fibers reinforced Al wires has been investigated.Their tensile strengthmay increase under treatment either at 500℃ for 2h or 550℃ for 1h,but decreaseover 600℃.After the strength tests of extracted fibers from composite wires,theSiC coating is an excellent protection to C fibers.EPMA and EDAX showed that theC/Al interface of the composite wires is stable under treatment below 600℃,butunstable at | CHEN Xinguo ZHENG Guobin SHEN Zuhong DU Haifeng Institute of Metal Research,Academia Sinica,Shenyang,China | 1992 | Acta Metallurgica Sinica(English Letters)1992，5，11： | 1 |

| 7 | Laparoscopic sigmoid vaginoplasty in women withMayer-Rokitansky-Kuster-Hauser syndrome显示文摘The feasibility and clinical therapeutic effects of laparoscopic sigmoid vaginoplasty in women with Mayer-Rokitansky-Kuster-Hauser syndrome(MRKHs)were explored.The records of 11 MRKHs patients who underwent laparoscopic sigmoid vaginoplasty from 2003 to 2005 were reviewed,and long-term results were evaluated by follow-up.The mean operating time was 234 min(range,130–300 min),the mean hospital stay was 9.4 days(range,7–15 days),and the mean hemoglobin drop was 1.91 g/dL(range,1.6–3.2 g/dL).A functional neovagina was created measuring 11 to 14 cm in length and twofingers in breadth in all patients.No introitus stenosis was observed.No intra-operative or postoperative bowel complication occurred.At the 3rd postoperative month,thefirst intercourse began.One patient was lost to follow-up.One had no intercourse and was required to wear vaginal mold occasionally.None of the other nine women(100%)complained of local irritation or dyspar-eunia.They were satisfied with their sexual life.The cosmetic results were excellent.The laparoscopic sigmoid vaginoplasty realizes to make a functional neovagina.The main advantage is its minimal invasiveness.It is an ideal procedure for MRKHs patients. | Yi SHEN Guobin WANG Zhoufang XIONG Kaixiong TAO Zehua WANG | 2009 | Frontiers of Medicine2009，3，3： | 0 |
| 8 | Mechanical behavior analysis of high power commercial lithium-ion batteries显示文摘In application,lithium-ion cells undergo expansion during cycling.The mechanical behavior and the impact of external stress on lithium-ion battery are important in vehicle application.In this work,18 Ah high power commercial cell with Li Ni_(0.5)Co_(0.2)Mn_(0.3)O_(2)/graphite electrode were adopted.A commercial compress machine was applied to monitor the mechanical characteristics under different stage of charge(SOC),lifetime and initial external force.The dynamic and steady force was obtained and the results show that the dynamic force increases as the SOC increasing,obviously.During the lifetime with high power driving mode,different external force is shown to have a great impact on the long-term cell performance,with higher stresses result in higher capacity decay rates and faster impedance increases.A proper initial external force(900 N)provides lower impedance increasing.Postmortem analysis of the cells with2000 N initial force suggests a close correlation between electrochemistry and mechanics in which higher initial force leads to higher direct current internal resistance(DCIR)increase rate.In addition,for the cell with higher external force,deformation of the cathode and thicker solid electrolyte interface(SEI)film on the surface of anode and separator are observed.Porosity reduction and closure was also verified after cycles which is an obstacle to the lithium ion transferring.The largest cause of the observed capacity decline was the loss of active lithium through autopsy analysis.In addition,for the cell with higher external force,deformation of the cathode and thicker SEI film on the surface of anode and separator are observed.Porosity reduction and closure was also verified after cycles which is an obstacle to the lithium ion transferring.The largest cause of the observed capacity decline was the loss of active lithium through autopsy analysis. | Ruicheng Shen Shaojun Niu Guobin Zhu Kai Wu Honghe Zheng | 2023 | Chinese Journal of Chemical Engineering2023，58，6： | 0 |
