Journal ArticleDOI
CuO/Cu2O nanoflake/nanowire heterostructure photocathode with enhanced surface area for photoelectrochemical solar energy conversion
Subish John,Somnath C. Roy +1 more
TL;DR: In this paper, the authors report the CuO/Cu2O nanoflake/nanowire heterostructure with the enhanced surface area directly grown on Cu foil through scalable process steps ensuring easy large-scale fabrication.
Journal ArticleDOI
High photoelectrochemical activity of CuO nanoflakes grown on Cu foil
TL;DR: In this article, a facile two-step synthesis process consisting of electrochemical anodization of Cu foil followed by low-temperature hydrothermal treatment at 100°C was proposed to obtain phase pure CuO nanostructures.
Journal ArticleDOI

Prashant Tyagi,Prashant Tyagi,Ch. Ramesh,Ch. Ramesh,Jyoti Kaswan,Jyoti Kaswan,Swati Dhua,Subish John,Ajay Kumar Shukla,Ajay Kumar Shukla,Somnath C. Roy,Sunil Singh Kushvaha,Sunil Singh Kushvaha,Senthil Kumar Muthusamy,Senthil Kumar Muthusamy +14 more
TL;DR: In this paper, a self-aligned single crystalline GaN array on flexible Ta metal foil using laser molecular beam epitaxy was reported, and the results demonstrate an effective way of fabricating well-aligned GaN nanorods on flexible metal foils for developing simple, relatively inexpensive, and flexible photo-electrodes for photocatalytic solar water splitting applications.
Journal ArticleDOI
Local probing of magnetoelectric coupling in BaTiO3-Ni 1–3 composites
TL;DR: In this article, the fabrication of BaTiO3-Ni magnetoelectric nanocomposites with both inner and outer surfaces of the nanotubes has been reported.
