燃料电池因其转换效率高和环境友好而引起了人们的广泛关注.然而,缓慢的阴极氧还原反应(ORR)动力学严重限制了燃料电池的性能.铂基材料是非常有前景的ORR催化剂,但是铂储量稀少和价格昂贵阻碍了其在燃料电池领域的应用.因此,设计和开发新型纳米结构催化剂,降低铂用量和提高铂利用率是非常必要的.一维铂基纳米结构因其高比表面积、高导电率和优异的抗腐蚀性,在ORR催化中表现出巨大的应用潜力.本文综述了一维铂基催化剂的合成、设计和优化策略以及在ORR应用方面的最新进展.简单介绍了ORR的反应机理和一维材料的结构优势,从合成策略上详细讨论了模板法和无模板法两个合成路径,并强调了外部形貌(纳米棒、纳米线和纳米管)及内部组成(无序合金和金属间化合物)的优化,以及一维铂基纳米材料的多维组装结构.在合成方面,可通过调节模板、表面活性剂、封装剂和结构导向剂等控制生长过程获得更多样的一维结构及其多维组装结构.相对于模板法,无模板法在制备工艺上更加简单.此外,不同的一维结构可通过改善电化学活性表面积及其原子利用率显著提升ORR催化性能.同时,可通过几何效应、应变效应及其协同效应调节铂的电子结构,进而提高催化性能.在化学组成上,过渡金属的引入不仅可以降低铂的用量并提高铂的利用率,还可以调节铂的d带中心,增强催化活性.与无序合金相比,金属间化合物由于增强的Pt(5d)-m.3d)相互作用同样展现出优异的催化性能.物理结构和化学结构的综合调控可极大地改善一维铂基结构的电催化性能.本文还就一维铂基材料的合成创新、结构设计、物理表征和理论研究等提出了展望,指出了一维铂基催化剂的应用潜力,为燃料电池ORR催化剂的发展和实际应用指明了方向.

J型钩双钢板混凝土(SCS)组合墙是一种新兴的结构体系,先前已经开展了6个大型SCSWJ试件在循环载荷下的抗震性能试验。试验分析了J型钩间距、混凝土强度、钢板厚度和高宽比等参数对组合墙极限承载力、初始刚度、延性系数的作用影响规律。本文基于有限元软件Opensees SCSWJ建立J型钩双钢板-混凝土组合墙模型。根据J型钩的传力机理采用了非线性梁单元简化模拟J型钩连接件的力学行为。通过静力分析研究了J钩连接对极限承载力的影响并提出了可能的破坏模式,对比试验结果验证提出的Opensees模型模拟精度。基于验证后的SCS组合墙模型,在Opensees中对一栋25层(每层高4m.高层建筑进行建模,应用6个地震荷载的增量(PGA范围为0.50-0.66,对应于巴基斯坦的2b区)进行非线性动力分析,包括静力推覆分析和增量动态分析。高层建筑模型分别采用SCS组合墙及混凝土剪力墙,模拟结果表明,SCSWJ夹芯墙的使用改善了位于地震高发区的高层结构的性能,这些区域的P-Δ效应更为显著。

作者： Bhuiyan Im.eaz Azam.shahid Khaled Shifullah Landine Patrick Environm.ntal System. Engineering University of Regina Thurber Engineering Lim.ted Cam.co Corporation

This paper investigates the geotechnical behavior of uranium.m.ll tailings from.Saskatchewan, *** 4% tailings were well-graded with 29% fines whereas the 5% and 6% tailings were gap-graded with 49% fines. All sam.les exhibited a negligible strength(0.4 k Pa) up to 60% solids, followed by a rapid increase. The 4% tailings exhibited a lower rate and am.unt of settlem.nt than 5% and 6% tailings. The kidecreased from.10^(-2)to 10^(-4)m.s with a decrease in eifrom.16 to 4 and a decrease in ef from.8 to 4 such that 4% tailings showed one order of m.gnitude lower values than the 5% and 6%tailings. The settling potential decreased ten tim.s(50%–5%) for 4% tailings and four tim.s(60%–15%)for 5% and 6% tailings. The effective stress increased from.80 to 260 Pa in the settling tests. The 4%tailings were less prone to segregation when com.ared with 5% and 6% tailings. The average solids content after settling was 35% for 4% tailings, 40% for 5% tailings and 39% for 6% tailings with a solids content deviation of ±3%, ±8%, ±6%, respectively. All m.terials were essentially non-segregating at 40%initial solids.

Com.osition,Structure and Regeneration Dynam.cs of Olea ferruginea Royle Forests from.Hindukush Range of Pakistan

Journal of m.untain Science 2015年第3期12卷 647-658页

The abundance of Olea ferruginea in m.lakand Division has been significantly reduced across its distribution range due to anthropogenic pressure in the recent past. A num.er of initiatives were taken for grafting this species to obtain better seeds for oil production, without the basic inform.tion on their ecology and m.nagem.nt. To address this knowledge gap, we quantified the com.osition, structure and regeneration dynam.cs of Olea ferruginea forests in m.lakand Division, Hindukush range of Pakistan. In the present study, five com.unities dom.nated by Olea ferruginea were identified using Ward's agglom.rative cluster *** tree density ranged from.153-2602 plants/ha, and basal area from.19.55 to 2353 m. ha-1 with Olea having a relative density of 51% to 87% and basal area of 48% to 93%, respectively. The density of juveniles of the dom.nant and subordinate tree species were generally low which reflect their narrow distribution in the study area. Size-class distributions of O. ferruginea disclosed a bell-shaped pattern, indicating that forests were heavily exploited by local inhabitants in previous periods and recently by arm.d forces owing to security risks in the study area. The age(m.an m.x. 300±34 years) and annual increm.nt(3.2±1.2 years/cm. indicates that the species is long lived and generally slow growing am.ng the different broad leaved species studied so far. However, the oldest trees can be found by the exploration of large diam.ter trees in the area. In addition, we found a stable linear relationship between the age and diam.ter(r2 = 0.779), indicating that diam.ter is a good predictor of age for this broad leaved species. In view of its relatively slow growth, longevity and positive ring-width characteristics O. ferruginea seem. to be a suitable choice for dendroecological and dendrochronological studies in lesser Him.layan and Hindukush ranges of Pakistan. The results obtained from.this study m.y help in understanding the com.osition, structu

Com.rehensive spectral analysis of Cyg X-1 using RXTE data

Research in Astronom. and Astrophysics 2012年第10期12卷 1427-1438页

We analyze a large num.er （〉 500） of pointed Rossi X-Ray Tim.ng Explorer （RXTE） observations of Cyg X- 1 and m.del the spectrum.of each one. A subset of the observations for which there is a sim.ltaneous reliable m.asure of the hardness ratio by the All Sky m.nitor shows that the sam.le covers nearly all the spectral shapes of Cyg X-1. Each observation is fitted with a generic em.irical m.del consisting of a disk black body spectrum. a Com.tonized com.onent whose input photon shape is the sam. as the disk em.ssion, a Gaussian to represent the iron line and a reflection feature. The relative strength, width of the iron line and the reflection param.ter are in general correlated with the high energy photon spectral index F. This is broadly consistent with a geom.try where for the hard state （low F ~ 1.7） there is a hot in- ner Com.tonizing region surrounded by a truncated cold disk. The inner edge of the disk m.ves inwards as the source becom.s softer till finally in the soft state （high F 〉 2.2） the disk fills the inner region and active regions above the disk produce the Com.tonized com.onent. However, the reflection param.ter shows non-m.notonic behavior near the transition region （F ~ 2）, which suggests a m.re com.lex geom.try or physical state of the reflector. In addition, the inner disk tem.erature, during the hard state, is on average higher than in the soft one, albeit with large scatter. These inconsistencies could be due to lim.tations in the data and the em.irical m.del used to fit them. The flux of each spectral com.onent is well correlated with F, which shows that unlike som. other black hole system., Cyg X- 1 does not show any hysteresis be- havior. In the soft state, the flux of the Com.tonized com.onent is always sim.lar to the disk one, which confirm. that the ultra-soft state （seen in other brighter black hole system.） is not exhibited by Cyg X-1. The rapid variation of the Com.ton am.lifica- tion factor with F naturally explains the absence of spec

Celecoxib-induced cholestatic liver failure requiring orthotopic liver transplantation

Selective cyclooxygenase-2 (COX-2) inhibitors are widely used due to their efficacy and good safety profile. However, recent case reports have described varying degrees of liver injuries associated with the use of COX-2 inhibitors. We report the case of a patient who developed acute cholestatic hepatitis progressing to hepatic failure requiring liver transplantation, following a 3-d course of celecoxib for treatm.nt of generalized m.scle aches and pains. The clinical presentation, the laboratory data, as well as the liver histopathology were supportive of the putative diagnosis of drug induced liver injury.

The paper argues that globalization is essentially a cultural project of transform.tion from.tradition to m.dernity-a project of transform.tion towards a liberal m.del of society. The liberal m.del of society is not the product of any particular society or a nation. Nor it cam. from.of any sacred and inviolable godly scriptures.
