A new single phase high entropy alloy, TiNiCoSnSb with half-Heusler (HH) structure is synthesized for the first time by vacuum arc melting (VAM) followed by ball-milling (BM). The BM step is necessary to obtain the single phase. Local electrode atom probe (LEAP) analysis showed that the elements are homogeneously and randomly distributed in the HH phase without any clustering tendency.

- The study examined how the type of metal substrate (copper, nickel, gold) affects the photocatalytic properties of anatase TiO2 coatings.
- The research utilized various techniques like X-ray diffraction and electron microscopy to analyze the structure and composition of the coatings.
- Results revealed that nickel substrates require less photon energy for TiO2 activation, while copper shows a higher band gap due to quantum effects, and gold enables easier electron transfer, needing minimal energy for conductivity.
