Covalent Functionalization of NiFe Layered Double Hydroxides using Tris(Hydroxymethyl)Aminomethane

Small, EarlyView.
Covalent functionalization of NiFe layered double hydroxides with tris(hydroxymethyl)aminomethane enables controlled growth, enhanced structural order, and improved processability. Temporary TRIS anchoring promotes stable water‐based inks and binder‐free electrode fabrication, leading to enhanced oxygen evolution activity and long‐term stability under ...

Horizontal oscillation of a capillary bridge between a spherical grain and a flat surface [PDF]

EPJ Web of Conferences
A granular system's behaviour can be significantly altered by humidity, as even small amounts of condensed liquid between grains affect particle movement.

Designing Elastic Softening Under Compression via Dipole–Dipole Interactions: The Case of Na2TiSiO5

Small, EarlyView.
Pressure usually stiffens solids, yet Na2TiSiO5 exhibits anomalous elastic softening under compression. Unlike conventional mechanisms driven by geometric rearrangements or electronic spin‐state transitions, the softening originates from enhanced dipole coupling along head‐to‐tail TiO5 chains.

Carnot-Like Heat Engines Versus Low-Dissipation Models

Entropy, 2017
In this paper, a comparison between two well-known finite time heat engine models is presented: the Carnot-like heat engine based on specific heat transfer laws between the cyclic system and the external heat baths and the Low-Dissipation model where ...

Simulating the aerodynamical resuspension of a granular bed of microparticles [PDF]

EPJ Web of Conferences
The deposition of micrometric particles in layers on various surfaces (e.g., ventilation ducts, industrial environments, nuclear reactors) has raised concerns due to potential resuspension in enclosed spaces or the atmosphere.

Point diffraction interferometry to measure local curvatures and caustics of noisy wave fronts: Application for determining optical properties of fish lenses [PDF]

Journal of the European Optical Society-Rapid Publications, 2015
The study of caustics is important because they contain information about the image formation properties of optical systems. In this work we use the concept of caustic as a set of focal points, and we have developed a second order approach theory to ...
