Pore size estimation in axon-mimicking microfibers with diffusion-relaxation MRI

Jean-Philippe Thiran, Erick Jorge Canales Rodriguez, Marco Pizzolato, Muhamed Barakovic, Tim Bjørn Dyrby

Purpose: This study aims to evaluate two distinct approaches for fiber radius estimation using diffusion-relaxation MRI data acquired in biomimetic microfiber phantoms that mimic hollow axons. The methods considered are the spherical mean power-law approac ...

Deriving Major Ion Concentrations at High Resolution from Continuous Electrical Conductivity Measurements in Karst Systems

Paolo Benettin

Time series of hydrochemical parameters support the investigation of dominant karst hydrological processes and conceptual model structures. Nevertheless, high costs for sample collection and analyses cause hydrochemical data to be rarely available at a suf ...

Morphology and Transport Characterization of Catalyst Layers for CO2 Reduction

Sophia Haussener, Francesca Lorenzutti

Gas diffusion electrodes (GDEs) help to reduce transport limitations in devices for electrochemical CO2 reduction. Homogenized modeling of such devices requires input of morphological characteristics and effective transport properties of the porous structu ...

Anionic character of the conduction band of sodium chloride

Klaus Kern, Abhishek Grewal

The alkali halides are ionic compounds. Each alkali atom donates an electron to a halogen atom, leading to ions with full shells. The valence band is mainly located on halogen atoms, while, in a traditional picture, the conduction band is mainly located on ...

Six new transformation pathways connecting simple crystal structures and common intermetallic crystal structures

Anirudh Raju Natarajan

Continuous pathways that connect different crystal structures can play a crucial role in determining the mechanisms with which structural phase transformations occur. The number of known pathways connecting metallic phases, such as the Bain path and the Bu ...

Nanocapillary confinement of imidazolium based ionic liquids

Aleksandra Radenovic, Sanjin Marion, Sebastian James Davis, Zeng-Qiang Wu

Room temperature ionic liquids are salts which are molten at or around room temperature without any added solvent or solution. In bulk they exhibit glass like dependence of conductivity with temperature as well as coupling of structural and transport prope ...

Patterns and driving forces of dimensionality-dependent charge density waves in 2H-type transition metal dichalcogenides

László Forró, Helmuth Berger

Charge density wave (CDW) is a startling quantum phenomenon, distorting a metallic lattice into an insulating state with a periodically modulated charge distribution. Astonishingly, such modulations appear in various patterns even within the same family of ...

Time-resolved formation of excited atomic and molecular states in XUV-induced nanoplasmas in ammonia clusters

Marcel Drabbels, Andrew Daniel Bonnar Clark

High intensity XUV radiation from a free-electron laser (FEL) was used to create a nanoplasma inside ammonia clusters with the intent of studying the resulting electron-ion interactions and their interplay with plasma evolution. In a plasma-like state, ele ...

Attosecond spectroscopy reveals alignment dependent core-hole dynamics in the ICl molecule

Hugo Jean Baptiste Marroux

The removal of electrons located in the core shells of molecules creates transient states that live between a few femtoseconds to attoseconds. Owing to these short lifetimes, time-resolved studies of these states are challenging and complex molecular dynam ...

Discovering hierarchies among intermetallic crystal structures

Anirudh Raju Natarajan

The crystal structure of a compound plays an important role in determining its properties. Here we analyze over 4000 intermetallic compounds, and we identify a hierarchical relationship between their crystal structures. By considering each intermetallic co ...
