A Field Guide to Non‐Onsager Quantum Oscillations in Metals
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. [...]

Applying Numerical Simulation to Model Varying Process and Cell Parameters during the Electrolyte Filling Process of Lithium‐Ion Batteries
Energy technology 13(4), 2401708 () [10.1002/ente.202401708]
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. [...]

Impact of Humidity on Water Dynamics and Electrical Conductivity in PEDOT:PSS/Cellulose Nanofibril Nanocomposite Films: Insights from Quasi-Elastic Neutron Scattering
Macromolecules 58(5), 2247 - 2258 () [10.1021/acs.macromol.4c02412]
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. [...]

How to compute a special function with near machine-precision accuracy
5th conference for Research Software Engineering in Germany, KarlsruheKarlsruhe, Germany, 25 Feb 2025 - 27 Feb 20252025-02-252025-02-27
Based on my experience as developer and maintainer of some numerical open-source libraries (libcerf, libkww, libformfactor), I will explain key concepts for writing code that computes a special function or integral with high accuracy and high speed.- Choose different numerical algorithms for different argument regions.- Don't be afraid of divergent series or ill-conditioned recursions. - Confine Chebyshev fits to small subregions.

Impact of roasting, high-pressure homogenization, and alkaline pH-shifting on hemp seed protein functionality
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. [...]

Wet spinning of sodium carboxymethyl cellulose–sodium caseinate hydrogel fibres: relationship between rheology and spinnability
Soft matter 22, 10.1039.D4SM00705K () [10.1039/D4SM00705K]
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).

A high-frequency artificial nerve based on homogeneously integrated organic electrochemical transistors
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.
