In Situ Amine Formation to Modulate MOF‐Derived PdIn N‐Doped Carbon Catalysts

Advanced Materials, EarlyView.
An amine‐assisted approach converts PdIn‐MOF into PdIn intermetallic nanoparticles embedded in N‐doped carbon. In situ‐generated amines trigger early Pd nucleation, producing smaller PdIn domains than direct pyrolysis. Amine sterics and basicity tune composition and particle size, while solvent and amine co‐determine textural features.

A new Rayleigh-like wave in guided propagation of antiplane waves in couple stress materials

Proceedings of the Royal Society A, 2020
Motivated by the unexpected appearance of shear horizontal Rayleigh surface waves, we investigate the mechanics of antiplane wave reflection and propagation in couple stress (CS) elastic materials. Surface waves arise by mode conversion at a free surface,

Simulation of the growth of the 3D Rayleigh-Taylor instability in Supernova Remnants using an expanding reference frame [PDF]

, 2010
Context: The Rayleigh-Taylor instabilities generated by the deceleration of a supernova remnant during the ejecta-dominated phase are known to produce finger-like structures in the matter distribution which modify the geometry of the remnant.

Dynamic Optical Lattices Through Conducting Polymer‐Gated Confinement

Advanced Materials, EarlyView.
The conducting polymer gate is incorporated into organic dielectric lattices to control the dynamic switching of nonlocal Mie resonances in the visible/NIR regions. The “closed gate” from oxidized PEDOT confines the light within dielectric nanocylinders and activates nonlocal Mie resonances, while the “opened gate” from reduced PEDOT facilitates ...
