Light-Enhanced Blue Energy Generation Using MoS2 Nanopores

Aleksandra Radenovic, Andras Kis, Martina Lihter, Michael Graf, Dmitrii Unuchek

Blue energy relies on the chemical potential difference between solutions of high and low ionic concentrations, potentially providing an independent energy source at estuaries around the world. The energy conversion relies on reverse electrodialysis via io ...

Fabrication and practical applications of molybdenum disulfide nanopores

Aleksandra Radenovic, Martina Lihter, Ke Liu, Michael Graf, Jiandong Feng, Mukeshchand Thakur

Among the different developed solid-state nanopores, nanopores constructed in a monolayer of molybdenum disulfide (MoS2) stand out as powerful devices for single-molecule analysis or osmotic power generation. Because the ionic current through a nanopore is ...

Mediated water electrolysis in biphasic systems

Hubert Girault, Pekka Eero Peljo, Heron Vrubel, Micheal Diarmaid Scanlon, Lucie Josette Renée Rivier

The concept of efficient electrolysis by linking photoelectrochemical biphasic H2 evolution and water oxidation processes in the cathodic and anodic compartments of an H-cell, respectively, is introduced. Overpotentials at the cathode and anode are minimis ...

Gel-free IEF in a membrane-sealed multicompartment cell for proteome prefractionation

Hubert Girault, Hoang-Trang Lam

A minidevice for performing gel-free proteome prefractionation via conventional IEF in soluble carrier ampholyte buffers is reported here. It consists of a compact block of poly-oxymethylene in which eight samples and two electrode chambers are machined. E ...
