An in situ and ex situ TEM study into the oxidation of titanium (IV) sulphide

TiS2 oxidation: moisture is the critical element preventing environmental stability The degradation dynamics of TiS2 reveal that the flakes oxidise in water and atmosphere, pointing towards moisture as the key driving force. A team led by Valeria Nicolosi at Trinity College Dublin used advanced elec...
