Applied Surface Science

• TSA-H shows only 4% photocurrent decay after prolonged UV illumination. • Two-step anodized TiO 2 nanotubes exhibit superior photocurrent stability. • Defect engineering in pure H 2 boosts donor density to 3.51 × 10 22 cm −3 . • PEC performance is more sensitive to H 2 atmosphere than anodization method. • XPS confirms highest oxygen vacancies in TSA-H, enhancing charge transport. This study in…

• Magnetically guided sharkskin MRE yields a robust superhydrophobic surface. • Retains WCA > 150° after 500 cm abrasion via self-regenerating superhydrophobicity. • Stable to water-jet shear and 90-day open-air exposure. • Compressive strength increased 59% due to magnetically aligned microchains. • SHIP incorporation and magnetic curing enhanced shear storage modulus and loss factor of SHS.
