Michael U. Niemann,Sesha S. Srinivasan,A.R. Phani,Ashok Kumar,D. Yogi Goswami,Elias K. Stefanakos +5 more
TL;DR: In this paper, a review of the application of nanostructured materials for storing atomic or molecular hydrogen is presented, where the synergistic effects of nanocrystalinity and nanocatalyst doping on the metal or complex hydrides for improving the thermodynamics and hydrogen reaction kinetics are discussed.
Journal ArticleDOI
Graphene Films and Ribbons for Sensing of O2, and 100 ppm of CO and NO2 in Practical Conditions
TL;DR: Graphene films and ribbons were grown on Ni-coated Si substrates using the microwave plasma enhanced chemical vapor deposition method, and the structure, morphology, and quality of graphene films and ribbon were reported in this article.
Journal ArticleDOI
Novel lactate and pH biosensor for skin and sweat analysis based on single walled carbon nanotubes
TL;DR: Carbon nanotubes (CNTs) were functionalized and employed in an electrochemical cell to serve as a biosensor to specifically detect either lactate or pH in an electrolyte solution of artificial sweat as discussed by the authors.
