Supramolecular Liquid Crystal Elastomer Adhesives: Role of Internal Damping and Hydrogen Bonding

Advanced Functional Materials, EarlyView.
The adhesion strength can be significantly enhanced through the molecular design of supramolecular liquid crystal elastomers (LCEs) that combine high internal damping from mesogen reorientation with abundant hydrogen‐bonding moieties. Solvent vapor annealing enables reversible, non‐thermal control of adhesion, offering potential for heat‐sensitive ...

Viscous flow of the Cu47-Ti34-Zr11-Ni8 glass forming alloy [PDF]

, 2000
The viscosity of the Cu47-Ti34-Zr11-Ni8 glass forming alloy was determined by beam bending experiments and by a noncontact oscillating drop technique. These viscosity data can be described with the Vogel-Fulcher-Tammann relation. Using the strong/fragile

Unveiling Phonon Contributions to Thermal Conductivity and the Applicability of the Wiedemann—Franz Law in Ruthenium and Tungsten Thin Films

Advanced Functional Materials, EarlyView.
Thermal transport in Ru and W thin films is studied using steady‐state thermoreflectance, ultrafast pump–probe spectroscopy, infrared‐visible spectroscopy, and computations. Significant Lorenz number deviations reveal strong phonon contributions, reaching 45% in Ru and 62% in W.

Strong gate coupling of high-Q nanomechanical resonators

, 2010
The detection of mechanical vibrations near the quantum limit is a formidable challenge since the displacement becomes vanishingly small when the number of phonon quanta tends towards zero.

Chemoselective Sequential Polymerization: An Approach Toward Mixed Plastic Waste Recycling

Advanced Functional Materials, EarlyView.
Inspired by biological protein metabolism, this study demonstrates the closed‐loop recycling of mixed synthetic polymers via ring‐closing depolymerization followed by a chemoselective sequential polymerizations process. The approach recovers pure polymers from mixed feedstocks, even in multilayer formats, highlighting a promising strategy to overcome a
