Distinguishing sodium-ion penetration and sustained transport in realistic hard carbon nanostructures
Carolina Cruz-Cardona, Andreea Hedes, Patrick Rowe +7
Hard carbons are promising anodes for sodium-ion energy storage, yet the relationship between their heterogeneous microstructure and sodium transport remains poorly understood. Her…
Advanced Spectroscopic Analyses on a:C-H Materials: Revisiting the EELS Characterization and its Coupling with multi-wavelength Raman Spectroscopy
L. Lajaunie, C. Pardanaud, C. Martin +4
Hydrogenated amorphous carbon thin films (a:C-H) are very promising materials for numerous applications. The growing of relevance of a:C-H is mainly due to the long-term stability…
Molybdenum diselenide-manganese porphyrin bifunctional electrocatalyst for hydrogen evolution reaction and selective hydrogen peroxide production
Antonia Kagkoura, Christina Stangel, Raul Arenal +1
Electrochemical reactions for hydrogen and hydrogen peroxide production are essential for energy conversion to diminish energy crisis, but still lack efficient electrocatalysts. De…
Crystalline Phase Effects on the Nonlinear Optical Response of MoS2 and WS2 Nanosheets
Michalis Stavrou, Nikolaos Chazapis, Eleni Nikoli +3
In the present work, some MoS2 and WS2 nanosheets were prepared and characterized. Depending on the preparation procedures, trigonal prismatic (2H) or octahedral (1T) coordination…
