Ultra-clean assembly of van der Waals heterostructures
Wendong Wang, Nicholas Clark, Matthew Hamer +24
Layer-by-layer assembly of van der Waals (vdW) heterostructures underpins new discoveries in solid state physics, material science and chemistry. Despite the successes, all current…
Doped graphene/carbon black hybrid catalyst giving enhanced oxygen reduction reaction activity with high resistance to corrosion in proton exchange membrane fuel cells
Zhaoqi Ji, Jianuo Chen, María Pérez-Page +6
Nitrogen doping of the carbon is an important method to improve the performance and durability of catalysts for proton exchange membrane fuel cells by platinum-nitrogen and carbon-…
Raman Fingerprints of Graphene Produced by Anodic Electrochemical Exfoliation
Vaiva Nagyte, Daniel J. Kelly, Alexandre Felten +11
Electrochemical exfoliation is one of the most promising methods for scalable production of graphene. However, limited understanding of its Raman spectrum as well as lack of measur…
Graphene-TiS heterojunction for selective polar vapor sensing at room temperature
Nassim Rafiefard, Azam Iraji zad, Ali Esfandiar +5
In this work, the room temperature polar vapor sensing behavior of two dimentional (2D) heterojunction Graphene-TiS3 materials and TiS3 nanoribbons is investigated. TiS3 nanoribbon…
