Switchable Supramolecular Adhesive by Tuning Interfacial Bonding and Modulus

Advanced Functional Materials, EarlyView.
The supramolecular adhesive (HyDiP) shows reversible adhesion and recyclability. In the dehydrated state, it is dense, stiff (E ≈445 MPa), transparent, and provides strong bonding with adhesion strengths up to 4.65 MPa. In the hydrated state, it becomes porous, soft (E ≈0.11 MPa), and detaches easily, enabling sustainable high‐strength applications ...

Machinability and tool wear mechanism in the high-speed milling of TiAl alloys with different microstructures

Journal of Materials Research and Technology
Titanium aluminides (TiAl) are potential candidates for replacing nickel-based superalloys in aircraft engines. This is due to TiAl alloys’ superiority in high-temperature strength, low density, and corrosion resistance.

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).

Fluorine‐Free Soft Nanocomposites for High‐Speed Liquid Impact Repellence

Advanced Functional Materials, EarlyView.
Fluorine‐free soft nanocomposite coatings are developed using silicone oil‐mediated mechanical‐stiffness control, enabling ‘dry’ liquid‐repellent surfaces that resist high‐speed water jet impacts up to ∼60 m/s. By tuning nanoparticle loading and oil content, the coatings also achieve >90% optical transparency, amphiphobicity with impact resistance to ...
