2D nanopores: fabrication, energy harvesting and field-effect sensing

Michael Graf

Solid-state nanopores are man-made, nano-sized openings in membranes separating two chambers containing an electrolyte solution. When applying an electric field across the membrane, the nanopore provides the only path for mobile ions to pass from one side ...

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 ...

The interfacial structure of water droplets in a hydrophobic liquid

Sylvie Roke, Nikolay Smolentsev

Nanoscopic and microscopic water droplets and ice crystals embedded in liquid hydrophobic surroundings are key components of aerosols, rocks, oil fields and the human body. The chemical properties of such droplets critically depend on the interfacial struc ...

Single-layer MoS2 nanopores as nanopower generators

Aleksandra Radenovic, Andras Kis, Ke Liu, Dumitru Dumcenco, Michael Graf, Dmitry Ovchinnikov, Jiandong Feng

Making use of the osmotic pressure difference between fresh water and seawater is an attractive, renewable and clean way to generate power and is known as 'blue energy'(1-3). Another electrokinetic phenomenon, called the streaming potential, occurs when an ...

Determining The Potential Of Salinity Gradient Energy Source Using An Exergy Analysis

Mixing of fresh (river) water and salty water (seawater or saline brine) in a control fashion would produces an electrical energy known as salinity gradient energy (SGE). Two main conversion technologies of SGE are membrane-based processes; pressure retard ...

Platinum nanopetal-based potassium sensors for acute cell death monitoring

Giovanni De Micheli, Sandro Carrara, Irene Taurino

Growing interest in the role of ions as cell death regulators has led to the consideration of K+, which plays a major role in events such as necrosis, apoptosis and osmotic shock. These mechanisms induce effluxes of K+, which can be m ...

Molecular Effects of Concentrated Solutes on Protein Hydration, Dynamics, and Electrostatics

Matteo Dal Peraro, Luciano Andres Abriata, Enrico Spiga

Most studies of protein structure and function are performed in dilute conditions, but proteins typically experience high solute concentrations in their physiological scenarios and biotechnological applications. High solute concentrations have well-known e ...

Microalloying for the controllable delay of precipitate formation in metal alloys

William Curtin

A model is presented to predict the effectiveness of dilute solutes in delaying precipitate formation, with application to natural and artificial aging in metal alloys. Control of aging is achieved via the binding, at natural aging temperatures, and releas ...
