As deposited NsARC TiO2. (a) Stainless-steel substrate with 10 μm thick coating. (b) Scanning Electron Microscope (SEM) image of coating surface morphology with mille-feuilles and strobili structures indicated. (c) SEM fracture surface cross-section showing mille-feuilles columns and strobili dendrites both with strong z-orientation. (d) High magnification SEM image of side-view of a mille-feuilles column. (e) Bright field TEM image of a mille-feuilles column, probably rotated 90° relative to (d).

Shape-changing element holds key to anti-bacterial coating

Undoubtedly, TiO2 has received much attention as a possible antimicrobial material due to its well-known photocatalytic activity (PCA) and self-cleaning properties. It is used in sunscreens...
