The Canopy Pavilion: A lightweight shading structure using a deployable auxetic linkage membrane

Mark Pauly, Dieter Dietz, Florin Isvoranu, Arthur François Blanc, Tian Chen, Etienne Bouleau

We present the Canopy Pavilion, a lightweight shading structure for a social gathering space. The shading surface is realized as a tensioned auxetic linkage membrane, composed of two double-curved anticlastic layers separated by a compression pole. The mem ...

Pressure-Induced Enlargement and Ionic Current Rectification in Symmetric Nanopores

Aleksandra Radenovic, Andrey Chernev, Sanjin Marion, Michal Daniel Macha, Sebastian James Davis

Nanopores in solid state membranes are a tool able to probe nanofluidic phenomena or can act as a single molecular sensor. They also have diverse applications in filtration, desalination, or osmotic power generation. Many of these applications involve chem ...

An Atomistic Look into Bio-inspired Nanoparticles and their Molecular Interactions with Cells

Francesco Stellacci, Alke Fink, Pablo Campomanes Ramos, Stefano Vanni

Nanoparticles (NPs) have sizes that approach those of pathogens and they can interact with the membranes of eukaryotic cells in an analogous fashion. Typically, NPs are taken up by the cell via the plasma membrane by receptor-mediated processes and subsequ ...

Elastic and dynamic properties of membrane phase-field models

Ignacio Pagonabarraga Mora

Phase-field models have been extensively used to study interfacial phenomena, from solidification to vesicle dynamics. In this article, we analyze a phase-field model that captures the relevant physical features that characterize biological membranes. We s ...
