Alloying elements partitioning in TiAl-Ru intermetallic alloys

Intermetallics, 1999
Abstract Ruthenium additions are of interest for increasing low-pH resistance as well as improving mechanical properties of TiAl. Two phase Ti-48 at% Al-0.5 at% Ru was investigated. The partitioning behaviour of alloying elements in this condition was investigated by atom-probe field-ion microscopy (AP-FIM).

Thermo‐Fluorescent Bactericidal Quantum Dots Based Smart Multifunctional Textiles via Molecular Surface Engineering and 3D‐Printed Interlocked Architectures

Advanced Healthcare Materials, EarlyView.
A versatile approach is presented for fabricating smart multifunctional textiles by integrating thermo‐fluorescent carbon dot/polymer nanocomposite coatings with 3D‐printed interlocked architectures. The fabrics exhibit temperature‐responsive fluorescence, durable hydrophobicity, strong antibacterial and antioxidant activity, and enhanced UV protection.
