寻找具有高本征活性的水氧化催化剂材料对许多清洁能源技术的发展至关重要.氢氧化物半导体对析氧反应具有一定的电催化活性.然而,该材料导电性较差,限制着其电催化本征活性的提升.本文提出一种兼具高导电性和高催化活性的半金属氢氧化物析氧电催化材料.通过阳离子掺杂和阴离子空位协同作用,镍铁水滑石半导体可转化为半金属材料,其电阻率降低了两个数量级.相应半金属氢氧化物阵列电极的电催化活性显著提升,在10 mA cm^(-2)电流密度下其析氧过电势仅为195 mV,Tafel斜率仅为40.9 mV dec^(-1),显著优于商用RuO_(2)催化剂(316 mV,99.6 mV dec^(-1)).原位拉曼光谱和理论计算结果表明,半金属氢氧化物可在较低过电位下转化为羟基氧化物中间体,有助于高价态金属活性位点的形成与稳定,从而提升材料的析氧本征活性.本研究表明,兼具优异导电性和催化活性的半金属氢氧化物可作为先进的电极材料.

Martensitic Transformation in Fe-Mn-Si Based Shape Memory.Alloy.

引用

Journal of Materials Science & Technology 1999年第2期15卷 111-116页

The critical driving force for martensitic transformation fcc ( gamma ) y.elds hcp ( epsilon ) in ternary.Fe-Mn-Si alloy. increases with the content of Mn and decreases with that of Si. Thermody.amical prediction of M//s in ternary.Fe-Mn-Si alloy. was established. The fcc ( gamma ) y.elds hcp ( epsilon ) martensitic transformation in Fe-Mn-Si is a semi-thermoelastic and the nucleation process does not strongly.depend on soft mode. Nucleation occurs directly.through an overlapping of stacking fault rather than pole mechanism, and it is suggested that stacking fault energy.(SFE) is the main factor controlling nucleation. Based on the phenomenological theory.of martensite cry.tallography. a shuffle on (0001)//h//c//p plane is required when d//1//1//1 does not equal d//0//0//0//2. The derived principal strain in Bain distortion is smaller, i, e., more reasonable than the values given by.Christian. Alloy.ng elements strengthening the austenite, lowering SFE of gamma phase and reducing T//N** gamma temperature may.be beneficial to shape memory.effect of Fe-Mn-Si based alloy.. Accordingly. Fe-Mn-Si-RE and Fe-Mn-Si-Cr-N (or Fe-Mn-Si-Ni-Cr-N) are worthy.to be recommended as shape memory.materials with improved shape memory.effect. (Edited author abstract) 48 Refs.

Surgical brain injury.may.result in irreversible neurological deficits. Our previous report showed that partial regeneration of a traumatic brain lesion is achieved by.implantation of collagen gly.osaminogly.an（CGM）. Matrix metalloproteinases（MMPs） may.play.an important role in neurogenesis but there is currently.a lack of studies display.ng the relationship between the stimulation of MMPs and neurogenesis after collagen gly.osaminogly.an implantation following surgical brain trauma. The present study.was carried out to further examine the expression of MMP2 and MMP9 after implantation of collagen gly.osaminogly.an（CGM） following surgical brain trauma. Using the animal model of surgically.induced brain lesion, we implanted CGM into the surgical trauma. Rats were thus divided into three groups：（1） sham operation group： craniotomy.only.（2） lesion（L） group： craniotomy.＋ surgical trauma lesion;（3） lesion ＋ CGM（L ＋ CGM） group： CGM implanted following craniotomy.and surgical trauma lesion. Cells positive for SOX2（marker of proliferating neural progenitor cells） and matrix metalloproteinases（MMP2 and MMP9） in the lesion boundary.zone were assay.d and analy.ed by.immunofluorescence and ELISA commercial kits, respectively. Our results demonstrated that following implantation of CGM after surgical brain trauma, significant increases in MMP2^＋/SOX2^＋ cells and MMP9^＋/SOX2^＋ cells were seen within the lesion boundary.zone in the L ＋ CGM group. Tissue protein concentrations of MMP2 and MMP9 also increased after CGM scaffold implantation. These findings suggest that implantation of a CGM scaffold alone after surgical brain trauma can enhance the expression of MMP2 and MMP9 accompanied by.neurogenesis.

A Mixed-control Mechanism Model of Proeutectoid Ferrite Growth under Non-equilibrium Interface Condition in Fe-C Alloy.

引用

Journal of Materials Science & Technology 2004年第5期20卷 561-566页

作者： RuihengWU Xuey.RUAN HongbingZHANG T.y.hsu DepartmentofPlasticity.echnology ShanghaiJiaoTongUniversityShanghai200030China Departmentof.MaterialsEngineering ShanghaiInstituteofTechnologyShanghai200233China SchoolofMaterialsScieuceaudEugineering ShanghaiJiaoTougUuiversityShanghai200030China

By.combining the α/γ interface migration and the carbon diffusion at the interface in Fe-C alloy., a mathematical model is constructed to describe the mixed-control mechanism for proeutectoid ferrite formation from austenite. In this model, the α/γ interface is treated as non-equilibrium interface, i.e., the carbon concentration of austenite at γ/α interface is obtained through theoretical calculation, instead of that assumed as the local equilibrium concentration. For isothermal precipitation of ferrite in Fe-C alloy., the calculated results show that the rate of interface migration decreases monotonically.during the whole process, while the rate of carbon diffusion from γ/α interface into austenite increases to a peak value and then decreases. The process of ferrite growth may.be considered as composed of three stages: the period of rapid growth, slow growth and finishing stage. The results also show that the carbon concentration of austenite at γ/α interface could not reach the thermody.amic equilibrium value even at the last stage of ferrite growth.
