Concentrations of railway metal theft and the locations of scrap-metal dealers [PDF]

, 2015
Metal theft has become a substantial crime problem in many areas. In response, several countries have introduced legislation to regulate scrap-metal recycling yards. However, at present there is little evidence to support this use of the market reduction

Fabrication of crystals from single metal atoms [PDF]

, 2014
Metal nanocrystals offer new concepts for the design of nanodevices with a range of potential applications. Currently the formation of metal nanocrystals cannot be controlled at the level of individual atoms. Here we describe a new general method for the
