Sentences with phrase «metal nitride»

Hui Huang from A * STAR's Singapore Institute of Manufacturing Technology and his colleagues from Nanyang Technological University and Jinan University, China, have fabricated asymmetric supercapacitors which incorporate metal nitride electrodes with stacked sheets of graphene.

Metal nitrides such as titanium nitride, which offer both high conductivity and capacitance, are a promising alternative, but they tend to oxidize in watery environments that limits their lifetime as an electrode.

The two electrodes were then separated in the asymmetric supercapacitor by a solid - state electrolyte, which prevented the oxidization of the metal nitrides.
