As the application of nanoscale structures becomes increasingly commonplace in modern technologies, the comprehensive modelling of the subject has taken centre stage in its understanding. Take the modern application of nanoscale texturing for optical anti-reflectance as an example here; ... Mehr lesen

Thermal decomposition of plastic waste results in gas products, mainly hydrocarbon molecules (C2-C6), which cannot be released to the atmosphere for environmental reasons. Here, we propose a secondary gas treatment to decompose the hydrocarbon gas products into smaller molecules by ... Mehr lesen

Electrochemical reduction of CO2 to value added chemicals is a promising strategy to mitigate its emission from atmosphere and close the carbon cycle. Although the knowledge on designing electrocatalysts for CO2 electroreduction exists, challenges are associated with developing CO2 ... Mehr lesen

In the framework of the Future Circular Collider (FCC) study, SRF (Superconducting Radio Frequency) cavities will be produced by applying niobium superconducting thin films onto copper substrate cavities. The copper cavities are traditionally produced by mechanical forming of two half ... Mehr lesen

A three-dimensional multiphase laboratory experiment was simulated with a view to evaluating the subsurface distribution of non-aqueous phase liquids (NAPL). The experiment was set-up to reconstruct the migration of hydrocarbon-leaks, occurring in the earth´s surface, predominantly ... Mehr lesen

Accumulation of plastic solid waste is a large share of municipal solid waste (MSW). Thermochemical treatment processes are a vital component of a sustainable integrated MSW management since they reduce the volume of the waste significantly. In conjunction with our efforts to develop ... Mehr lesen

A gearbox used in a vacuum cleaner robot is evaluated regarding noise and vibration in COMSOL Multiphysics®, using the Multibody Dynamics and the Acoustics Module. The real gearbox is powered by a DC motor and consists of four plastic helical gears forming a gear train and is used to ... Mehr lesen

Calorimetry is the method of choice for determining one of the most elementary physical quantities: heat, Q [in J]. Depending on the individual issue a wide range of techniques, devices and methods are available for users [1]. One approach is called isothermal microcalorimetry (IMC). It ... Mehr lesen

High temperature and pressure alkaline electrolysis is an innovative and promising technology for water electrolysis for hydrogen production. Introducing simulation at early stage development allows to study the effect of the microstructure parameters on performance and guide the ... Mehr lesen

The present work introduces a new methodology, based on COMSOL Multiphysics® Application Builder, to account for the “beam trapping” effect in multiphysical modelling of laser welding. Incident intensities involved in laser welding processes are high enough to induce material ... Mehr lesen
