| 1 | Electroplastic Tensile Behavior of 5A90 Al–Li Alloys显示文摘The electroplastic(EP) tensile properties of 5A90 Al–Li alloys compared with thermal tension were investigated.The microstructural variation at different conditions was observed by SEM and TEM.The current density significantly influences the elongation and the flow stress.With increasing current density,wider and deeper dimples on the fracture surfaces and less dislocation density and pile-ups in the EP tension samples were observed compared with roomtemperature and thermal tension,which indicates the plasticity improvement and flow stress reduction.The EP effect(EPE) mainly results from a comprehensive function of Joule heating and pure EPE.Among them,Joule heating effect is perhaps a dominant factor. | Pengchao Song Xifeng Li Wei Ding Jun Chen | 2014 | Acta Metallurgica Sinica(English Letters)2014，27，4： | 7 |

| 6 | Environmentally friendly wollastonite@TiO2 composite particles prepared by a mechano-chemical method显示文摘Core-shell wollastonite@ TiO2(WOT)composite particles are prepared by a mechano-chemical method (MCM)to improve the dispersion of TiO2and reduce its dosage,and to achieve synergistic effects with the wollastonite mineral.The crystal structure,morphology,functional groups,and pigment properties of the as-prepared composite powders are determined.The W@T composite particles are formed by van der Waals force in addition to electrostatic attraction and chemical bonding.The anatase TiO2coating is anchored on the woUastonite surface by Si-O-Ti and Ca-O-Ti bonds.The W@T powders possess excellent characteristics such as whiteness of 96.6%,hiding power of 17.97g/m^2,and oil absorption of 22.72g/100g.The properties of the W@T composite are similar to those of TiO2and the former,which is much cheaper,can potentially substitute the latter as a white paint in many applications. | Xifeng Hou Yihe Zhang Hao Ding Paul K.Chu | 2018 | Particuology2018，16，5： | 1 |
| 7 | Influence of Strain Rate on Tensile Characteristics of SUS304 Metastable Austenitic Stainless Steel显示文摘The microstructure characteristics and plastic deformation behavior of SUS304 metastable austenitic stainless steel sheets have been investigated during tensile process at diferent strain rates at room temperature.The yield stress continuously increases with strain rates due to low fraction of martensite transformed from austenite at 0.2%plastic stain.While the ultimate tensile stress(UTS)and elongation gradually decreases and then slightly increases with increase in strain rate from 0.0005 s 1to 0.1 s 1,which is attributed to the variation of the martensite fraction that is afected seriously by adiabatic heating.A higher temperature increase in the tensile specimens restricts the martensitic transformation at high strain rate.The strain rate of 0.1 s 1is considered as a transition deformation rate from quasi-static state to plastic forming,where the transformed martensitic content is very small in a higher strain rate range.Anomalous stress peaks in the later half stage of deformation occur at a very low strain rate(i.e.,0.0005 s 1)result from X-shaped strain localization repeatedly sweeping over the specimen.With increasing strain rates,the variation of dimple number density follows similar trend as that of UTS and ductility because martensite fraction mostly influences void nucleation and growth. | Xifeng LI Jun CHEN Liyan YE Wei DING Pengchao SONG | 2013 | Acta Metallurgica Sinica(English Letters)2013，26，6： | 0 |
| 8 | Tumor necrosis factor-stimulated gene-6 ameliorates early brain injury after subarachnoid hemorrhage by suppressing NLRC4 inflammasome-mediated astrocyte pyroptosis显示文摘Subarachnoid hemorrhage is associated with high morbidity and mortality and lacks effective treatment.Pyroptosis is a crucial mechanism underlying early brain injury after subarachnoid hemorrhage.Previous studies have confirmed that tumor necrosis factor-stimulated gene-6(TSG-6)can exert a neuroprotective effect by suppressing oxidative stress and apoptosis.However,no study to date has explored whether TSG-6 can alleviate pyroptosis in early brain injury after subarachnoid hemorrhage.In this study,a C57BL/6J mouse model of subarachnoid hemorrhage was established using the endovascular perforation method.Our results indicated that TSG-6 expression was predominantly detected in astrocytes,along with NLRC4 and gasdermin-D(GSDMD).The expression of NLRC4,GSDMD and its N-terminal domain(GSDMD-N),and cleaved caspase-1 was significantly enhanced after subarachnoid hemorrhage and accompanied by brain edema and neurological impairment.To explore how TSG-6 affects pyroptosis during early brain injury after subarachnoid hemorrhage,recombinant human TSG-6 or a siRNA targeting TSG-6 was injected into the cerebral ventricles.Exogenous TSG-6 administration downregulated the expression of NLRC4 and pyroptosis-associated proteins and alleviated brain edema and neurological deficits.Moreover,TSG-6 knockdown further increased the expression of NLRC4,which was accompanied by more severe astrocyte pyroptosis.In summary,our study revealed that TSG-6 provides neuroprotection against early brain injury after subarachnoid hemorrhage by suppressing NLRC4 inflammasome activation-induced astrocyte pyroptosis. | Mingxiang Ding Lei Jin Boyang Wei Wenping Cheng Wenchao Liu Xifeng Li Chuanzhi Duan | 2024 | Neural Regeneration Research2024，19，5： | 0 |
