There are a number of trace elements that until recently were only considered to be laboratory curiosities but which have now become essential components in a variety of applications ranging from information and communication technologies, semiconductors, electronic displays and optic/photonic and ‘green energy’ related technologies. Their current strategic importance is such that these elements have now been labeled as ‘energy-critical elements’ or ‘technology-critical elements’ (TCEs) and initiatives at national levels are underway to secure their availability in the coming years.

NOTICE, a EU COST action focused on the study of TCEs run from April 2015 to April 2019. Its objective was the creation of a network of scientists working and interested on TCEs, ranging from an environmental perspective to potential human health threats.
