Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Wide-Field Spectral Super-Resolution Mapping of Optically Active Defects in Hexagonal Boron Nitride

Aleksandra Radenovic, Vytautas Navikas, Evgenii Glushkov, Jiandong Feng, Jean Camille Benjamin Comtet

Point defects can have significant impact on the mechanical, electronic, and optical properties of materials. The development of robust, multidimensional, high-throughput, and large-scale characterization techniques of defects is thus crucial for the estab ...

Fabrication and practical applications of molybdenum disulfide nanopores

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

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 ...

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 ...

Molecular sensing device

Aleksandra Radenovic, Ke Liu, Jiandong Feng

Molecular sensing system including: a sensing device (5) comprising at least one support layer (10), and an active layer (6) mounted on said support layer and having at least one nano-pore (12) configured for translocation of a molecular analyte (18) there ...

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 ...

Emergent behaviour from electron-transport properties is routinely observed in systems with dimensions approaching the nanoscale(1). However, analogous mesoscopic behaviour resulting from ionic transport has so far not been observed, most probably because ...

Nanopore forming method and uses thereof

Aleksandra Radenovic, Ke Liu, Jiandong Feng

Method for making nanopores in thin layers or monolayers of transition metal dichalcogenides comprising the steps of provinding a suspended transistion metal dichalcogenide layer (1) in an electrolyte (2), applying a transmembrane voltage (V) high enough t ...

Electrochemical Reaction in Single Layer MoS2: nanopores opened atom by atom

Aleksandra Radenovic, Andras Kis, Duncan Thomas Lindsay Alexander, Dumitru Dumcenco, Martina Lihter, Michael Graf, Ke Liu, Jiandong Feng, Roman Bulushev, Daria Krasnozhon

Ultrathin nanopore membranes based on 2D materials have demonstrated ultimate resolution toward DNA sequencing. Among them, molybdenum disulfide (MoS2) shows long-term stability as well as superior sensitivity enabling high throughput performance. The trad ...
