Many electronic and electrochemical devices rely on the exchange of light elements such as hydrogen and oxygen with the environment. Understanding and tailoring the device functionality requires accurate information about the concentration and chemical bonding of such species inside a solid, which is particularly difficult if several species are exchanged.

Quantum oscillation (QO) measurements constitute a powerful method to measure the Fermi surface (FS) properties of metals. The observation of QOs is usually taken as strong evidence for the existence of extremal cross-sectional areas of the FS according to the famous Onsager relation. [...]

The electrolyte filling process is considered one of the bottlenecks of lithium-ion battery production due mainly to the long electrolyte wetting times. Additionally, the required experimental process design is time and material-intensive, increasing the development costs of new materials or cell designs. [...]

The water dynamics in a nanocomposite film thatconsists of the electrically conductive poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) and cellulosenanofibrils (CNFs) have been investigated during three cyclesof exposure to low and high relative humidity (RH = 5% and 85%,respectively) using quasi-elastic neutron scattering (QENS). Theobtained dynamical structure factors are transformed into theimaginary part of the dynamic susceptibility to better differentiatebetween the individual relaxation processes. [...]

Hemp seed proteins have garnered significant research attention in recent years; however, the poor functional properties of hemp protein limit their use in many industrial applications. In this study, we investigate the effects of roasting, high-pressure homogenization, and alkaline pH-shifting on hemp protein structure and functional properties. [...]

Mimicking the fibrous structures of meat is a significant challenge as natural plant protein assemblies lack the fibrous organisation ubiquitous in mammalian muscle tissues. In this work, wet-spun hydrogel fibres resembling the anisotropic fibrous microstructure of meat are fabricated using carboxymethyl cellulose as a model polysaccharide and sodium caseinate as a model protein which are crosslinked using 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC). [...]

Coptis teeta rhizomes are a rich source of bioactive phytochemicals with significant applications in the food and nutraceutical industries. Standardized methods and solvent compositions are crucial to sustainably maximize bioactive yield while ensuring industrial feasibility. [...]

Artificial nerves that are capable of sensing, processing and memory functions at bio-realistic frequencies are of potential use in nerve repair and brain–machine interfaces. n-type organic electrochemical transistors are a possible building block for artificial nerves, as their positive-potential-triggered potentiation behaviour can mimic that of biological cells.
