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.","PeriodicalId":20208,"journal":{"name":"Platinum Metals Review","volume":"58 1","pages":"93-98"},"PeriodicalIF":0.0,"publicationDate":"2014-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1595/147106714X679458","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67346549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This conference was dedicated to the 120th anniversary of Professor Ilya Il’ich Chernyaev (1893–1966) and the 70th anniversary of the Gulidov Krasnoyarsk Non-Ferrous Metals Plant; it was also a celebration of 70 years since the fi rst International Chernyaev Conference on Chemistry, Analysis and Technology of Platinum Group Metals, which was held in 1943 in Sverdlovsk (now Yekaterinburg) under the chairmanship of Professor Chernyaev. All aspects of chemistry, analysis and especially refi ning of platinum group metals (pgms) are traditionally discussed during the conference. Strong industrial participation is an important part of the Chernyaev Conference series (1). More than 200 participants attended Chernyaev2013 from Russia, Portugal, Norway, Finland, Latvia and Kazakhstan with 10 plenary lectures, 100 oral and 65 poster presentations divided into four sections:  Chemistry of pgms and gold compounds;  Analysis of pgms and Au;  Production technology of pgms and Au;  Application of pgms and Au in industry, catalysis and medicine. The fi rst school for young scientists followed after the conference and included four plenary lectures and thirteen oral presentations.","PeriodicalId":20208,"journal":{"name":"Platinum Metals Review","volume":"58 1","pages":"82-86"},"PeriodicalIF":0.0,"publicationDate":"2014-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1595/147106714X679467","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67346585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":20208,"journal":{"name":"Platinum Metals Review","volume":"58 1","pages":"68-81"},"PeriodicalIF":0.0,"publicationDate":"2014-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1595/147106714X679287","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67346541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":20208,"journal":{"name":"Platinum Metals Review","volume":"58 1","pages":"20-30"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1595/147106713X675183","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67346429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":20208,"journal":{"name":"Platinum Metals Review","volume":"58 1","pages":"3-19"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1595/147106714X675768","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67346487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
