Experimental study of sand grains behavior at their contacts with force- and displacement-controlled sliding tests

Underground Space, 2017
Discrete element modeling requires the proper quantification of the behavior of grains at their contacts including the normal force – displacement and tangential force – displacement relationships to be used as input for contact modeling purposes.

Light-Mediated Collective Atomic Motion in an Optical Lattice Coupled to a Membrane

, 2018
We observe effects of collective atomic motion in a one-dimensional optical lattice coupled to an optomechanical system. In this hybrid atom-optomechanical system, the lattice light generates a coupling between the lattice atoms as well as between atoms ...

Micromechanical modelling of ferroelectrics

Current Opinion in Solid State and Materials Science, 2005
The wide range of applications of ferroelectrics is matched by an equally wide range of modelling approaches. This article reviews recent micromechanical models of ferroelectric switching. The development of models is traced, from discrete switching models that neglect grain-to-grain interaction, through to incremental switching models that account for

Ultrastrong TEMPO‐Oxidized Densified Bamboo via Interface Decoupling and Hierarchical Toughening

Advanced Science, EarlyView.
This study develops TEMPO‐oxidized densified bamboo that achieves ultrahigh strength and toughness by decoupling rigid hydrogen bonds into reversible van der Waals interactions. TEMPO oxidation reorganizes the cellulose hydrogen‐bonding network, facilitating energy dissipation via reversible interactions, thereby establishing a general strategy to ...

A Dynamic 3D Human Liver Sinusoid Model for Mechanistic Interrogation of Fontan‐Associated Liver Disease

Advanced Science, EarlyView.
This study presents a perfusable 3D bioengineered liver sinusoid platform that integrates biofabrication, 3D cell culture, controlled hemodynamics, and multiparametric characterization to model Fontan‐associated liver disease. By decoupling pressure and hypoxia effects, the system reveals early mechanobiological and profibrotic responses under ...
