In South Africa researchers in this field form a small but strong group that originated at the University of Pretoria. In this article a brief overview is firstly given on the international increase in interest and activities in this research field. Secondly the research field is viewed from a South African perspective. Examples of research projects are discussed, as well as the career path that leads to research in this field. Finally local activities and existing international ties are considered. The aim of this article is to give a South African overview of the research field and activities, hoping to motivate and stimulate research in this important and growing field.","PeriodicalId":30428,"journal":{"name":"South African Journal of Science and Technology","volume":"31 1","pages":"7"},"PeriodicalIF":0.0,"publicationDate":"2012-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70516050","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}
