Johnson Matthey Emission Control Technologies, Orchard Road, Royston, Hertfordshire SG8 5HE, UK Email: robert.hanley@matthey.com “Palladium-Catalyzed Coupling Reactions”, published by Wiley in 2013, is a comprehensive handbook and guide to modern aspects of this reaction type. The book focuses on state of the art techniques. The use of different reaction media, catalyst recycling, supported catalysts, microwave assisted synthesis and continuous fl ow reaction systems are all examined, making this book an excellent resource. The book avoids delving into the specifi cs of each type of coupling reaction and instead presents a variety of topics, discussing recent progress and potential future work in each given area. It was edited by Arpad Molnar, a Professor of Chemistry in the University of Szeged, Hungary, who has no less than 200 publications to his name. Numerous research papers in the fi eld of catalyst development, coupled with review papers on many of the subjects covered in this book, qualify Professor Molnar for his position of editor. The content of this book covers fi ve general topics: an introduction and background to Pd-catalysed coupling reactions, Pd catalysts on various support materials, coupling reactions in different reaction media, reaction conditions for coupling reactions and industrial applications of Pd catalysed coupling reactions.

*Email: bgpollet@hysasystems.org The Hydrogen South Africa (HySA) programme is based upon the benefi ciation of South Africa’s large platinum group metal (pgm) resources. The present article summarises some of the progress by HySA Systems, one of the three Competence Centres under the HySA Programme, since 2008. Work has been carried out on membrane electrode assembly and stack development for high-temperature proton exchange membrane fuel cells (HT-PEMFCs) for use in combined heat and power (CHP) supplied by natural gas and hydrogen fuelled vehicle (HFV) applications. The emphasis is on improved carbon monoxide tolerance and simplifi ed heat and humidity management, allowing simpler fuel cell systems to be designed. Metal hydrides modifi ed with palladium are being explored as poisoning-tolerant hydrogen storage materials for stationary and special mobile applications, and metal organic frameworks (MOFs) modifi ed with platinum as light-weight hydrogen storage with a high hydrogen storage capacity. Lastly research into hydrogen purifi cation using Pd membrane reactors is focused on membrane support synthesis, hollow fi bre seeding and development of the plating procedure.
*电子邮件:bgpollet@hysasystems.org南非氢(HySA)计划基于南非大型铂族金属(pgm)资源的收益。本文总结了自2008年以来HySA系统的一些进展,HySA系统是HySA计划下的三个能力中心之一。高温质子交换膜燃料电池(ht - pemfc)用于天然气和氢燃料汽车(HFV)提供的热电联产(CHP)的膜电极组装和堆栈开发工作已经开展。重点是提高一氧化碳耐受性和简化热量和湿度管理,允许更简单的燃料电池系统的设计。钯修饰的金属氢化物正在被探索作为固定和特殊移动应用的耐毒性储氢材料,以及铂修饰的金属有机框架(mof)作为具有高储氢容量的轻质储氢材料。最后对钯膜反应器的氢净化研究进行了重点介绍,包括膜载体的合成、中空纤维的播种和镀工艺的发展。

High Temperature Thermomechanical Properties of Titanium-Rhodium-based Alloys Containing Scandium 含钪钛-铑基合金的高温热机械性能

**Email: selena@ipms.kiev.ua At high temperatures, the equiatomic binary compounds formed by Groups 4 and 8 transition metals are known to undergo martensitic transformation, which may be accompanied by a shape memory effect. Among these compounds, titanium-rhodium (TiRh) is of special interest not only because it undergoes two martensitic transformations at high temperature, for one of which the shape memory effect has been observed, but also because it demonstrates unusual shape recovery behaviour at temperatures higher than 400oC. The present work focuses upon the thermomechanical and mechanical properties of 50 at% rhodiumscandium-titanium ternary alloys where Ti is substituted by Sc. These alloys were investigated for the first time using electrical resistance, dilatometry and three-point bending techniques in the temperature range 20oC to 850oC. It was found that the sample with 0.1 at% Sc exhibited full shape restoration in the ranges of both martensitic transformations at ~340oC and ~750oC. Two-way shape recovery was also observed. A small temperature hysteresis, desirable for alloys used in actuator applications, is present in TiRh and Rh-Sc-Ti alloys. Both TiRh and Sc-containing alloys exhibit continuity of the deformation process on cooling and shape restoration on heating in a wide range of temperatures. This feature of both TiRh and Rh-Sc-Ti alloys implies the possibility of their application in different heat-regulating elements at temperature ranges from room temperature to 850oC.
**Email: selena@ipms.kiev.ua已知在高温下,由第4族和第8族过渡金属形成的等原子二元化合物会发生马氏体相变,这可能伴随着形状记忆效应。在这些化合物中,钛铑(TiRh)是特别感兴趣的,不仅因为它在高温下经历了两次马氏体转变,其中一个已经观察到形状记忆效应,而且因为它在高于400℃的温度下表现出不同寻常的形状恢复行为。本文研究了以Sc代替Ti的50% at%铑-钪-钛三元合金的热力学和力学性能。首次采用电阻法、膨胀法和三点弯曲法在20℃至850℃的温度范围内对这些合金进行了研究。结果表明,在~340oC和~750oC温度下,Sc含量为0.1的样品在~340oC和~750oC的马氏体相变范围内均表现出完全的形状恢复。还观察到双向形状恢复。TiRh和Rh-Sc-Ti合金具有较小的温度滞后,这是执行器应用中使用的合金所需要的。在较宽的温度范围内,TiRh和sc合金在冷却和加热时均表现出变形过程的连续性和形状恢复。TiRh和Rh-Sc-Ti合金的这一特性意味着它们可以在室温到850℃的温度范围内应用于不同的热调节元件。

*Email: edoardo.bemporad@uniroma3.it Recently, the increasing importance and scope of nanotechnology has extended the need for high resolution characterisation tools beyond their traditional domains. As a consequence, advanced high-resolution tools at the nanoscale are now increasingly used in research and development (RD and nanoindentation testing. After a brief description of both techniques (architecture, probe-sample interaction basics and operation modes), the effectiveness of this combined approach is demonstrated for microstructural and nanomechanical investigations on very small samples. The advantages are low cost, fast and site-specific sample preparation for transition electron microscopy (TEM) analysis; study of the mechanical hardening effect on microstructure and hardness profile at the micron scale; failure analysis; and understanding of plasticity and elasticity behaviour. Two specific case studies related to a platinum-copper alloy for jewellery use and a platinum-rhodium alloy for sensor manufacturing are presented and discussed.
*电子邮件:edoardo.bemporad@uniroma3.it最近,纳米技术的重要性和范围的增加已经扩展了对传统领域之外的高分辨率表征工具的需求。因此,先进的纳米级高分辨率工具现在越来越多地用于研究和开发(RD)和纳米压痕测试。在对这两种技术(结构、探针-样品相互作用基础和操作模式)的简要描述之后,这种组合方法的有效性在非常小的样品上进行了微观结构和纳米力学研究。该方法的优点是成本低、速度快、可用于转移电子显微镜(TEM)分析的定点样品制备;机械硬化对微观组织和显微硬度分布的影响研究失效分析;以及对可塑性和弹性行为的理解。两个具体的案例研究有关铂铜合金用于珠宝和铂铑合金用于传感器制造提出和讨论。
