Graphene/SiC dies for electrochemical blood-type sensing; pp. 207–213 [PDF]
Proceedings of the Estonian Academy of Sciences, 2019 We discuss graphene-on-SiC dies for blood-type sensing. For the sensor application, chemical species to be detected adsorb on the graphene surface and act as electron donors or acceptors resulting in resistance changes of the graphene channel.

All nitride asymmetric supercapacitors of niobium titanium nitride-vanadium nitride
Journal of Power Sources, 2021 Abstract Metal nitrides are potential electrode materials for supercapacitors because of their high conductivity, high capacitance and good corrosion resistance. Herein, we present a general strategy to prepare self-standing bimetallic nitride thin film nanostructures using magnetron co-sputtering and further to boost their electrochemical ...
