Transport across thin membranes: Effective solute flux jump

François Gallaire, Pier Giuseppe Ledda, Giuseppe Antonio Zampogna

A model to describe the transport across membranes of chemical species dissolved in an incompressible flow is developed via homogenization. The asymptotic matching between the microscopic and macroscopic solute concentration fields leads to a solute flux j ...

Crystallization of Size-Selective Nanopores in Graphene for Gas Separation

Nanoporous single-layer graphene (N-SLG) membranes, owing to their single-atom thinness, have the potential to exceed the permeance and selectivity limits of gas separation membranes. However, two key issues in the top-down N-SLG synthesis need to be addre ...

Chlorothalonil transformation products in drinking water resources: Widespread and challenging to abate

Urs von Gunten, Juliane Hollender

Chlorothalonil, a fungicide applied for decades worldwide, has recently been banned in the European Union (EU) and Switzerland due to its carcinogenicity and the presence of potentially toxic transformation products (TPs) in groundwater. The spread and con ...

Shear Stress-Responsive Polymersome Nanoreactors Inspired by the Marine Bioluminescence of Dinoflagellates

Esther Amstad, Antoine Claude Jean Vian

Some marine plankton called dinoflagellates emit light in response to the movement of surrounding water, resulting in a phenomenon called milky seas or sea sparkle. The underlying concept, a shear-stress induced permeabilisation of biocatalytic reaction co ...

Machine Learning-Guided Approach for Studying Solvation Environments

Sandip De, Yasemin Basdogan

Molecular-level understanding and characterization of solvation environments are often needed across chemistry, biology, and engineering. Toward practical modeling of local solvation effects of any solute in any solvent, we report a static and all-quantum ...

Triboelectric effect to harness fluid flow energy

Danick Briand, Rubaiyet Iftekharul Haque, Amr Yehia Hussien Mahmoud Arafat

We are reporting energy scavenging from fluid flows inside tubular structures using triboelectric effects. Two separate designs of triboelectric generators are proposed. A tubular design that uses liquid-solid interaction mechanism for water, and freestand ...

Selectively Permeable Double Emulsions

Esther Amstad, Irvine Lian Hao Ong

Natural organisms are made of different types of microcompartments, many of which are enclosed by cell membranes. For these organisms to display a proper function, the microcompartments must be selectively permeable. For example, cell membranes are typical ...

2D materials as an emerging platform for nanopore-based power generation

Aleksandra Radenovic, Sanjin Marion, Michal Daniel Macha

Osmotic power generation, the extraction of power from mixing salt solutions of different concentrations, can provide an efficient power source for both nanoscale and industrial-level applications. Power is generated using ion-selective channels or pores o ...

Osmotic power generator

Aleksandra Radenovic, Jiandong Feng

An osmotic power generator comprising an active membrane supported in a housing, at least a first chamber portion disposed on a first side of the active membrane for receiving a first electrolyte liquid and a second chamber portion disposed on a second sid ...

Microfluidic Production of Capsules-in-Capsules for Programed Release of Multiple Ingredients

Esther Amstad

Capsules with thin shells have a high‐loading capacity and are thus well‐suited containers for reagents that must be stored in confined volumes. Capsules contained in larger capsules, so‐called double capsules, allow the encapsulation of distinct reagents ...
