In a recent study, researchers from the Indian Institute of Technology Kanpur have explored the use of a new blend of chromium (III) as an eco-friendly electrolyte for depositing chromium-based coatings on metallic barrels. They reinforced chromium with carbon nanotubes (CNTs) and a ceramic compound called yttria stabilised zirconia (YSZ), to improve the properties of the coat.
By precisely tuning the metamaterial structures, researchers create a near-perfect light trap synchronised with molecular vibrations, paving the way for advanced sensors and optical devices.
