INTRODUCTION: The “Schrödinger equation” is usually associated with quantum mechanics, however for the nonlinear version (NLSE), there are applications outside the realm of quantum mechanics. NLSE appears in branches of physics like a) the quantum physics Bose-Einstein condensation ... En savoir plus
Climate change is a short-term problem which can no longer be ignored and affects everything, from global food security to geopolitics and economics: extreme weather phenomena, falling crops yields, decrease of water availability, sea level rise, extinction of several animal species, are ...

Stability of food webs under environmental changes like e.g. climate change depends on the effect of a time-dependent parameter like temperature on population level and community level. As predator-prey relationships depend on individual size, all populations involved must be size ... En savoir plus
The objective of this simulation model is to enhance the thermal behavior in a MEMS Gas-Chromatographer (GC) pre-concentrator for Volatile Organic Compounds (VOCs) carried by Helium gas. The simulation plays a critical role in estimating voltages, thermal time constants, and spatial ... En savoir plus
The low-temperature electrochemical conversion of CO₂ to ethylene offers significant potential for reducing the chemical industry’s reliance on fossil fuels. Despite recent advancements, the key performance indicators—activity, selectivity, and durability—are insufficient for industrial ... En savoir plus
Modified Atmosphere Packaging (MAP) is a widely applied technology for the shelf-life extension of fresh and fresh-cut fruits and vegetables. This technique relies on modifying the gas composition inside de package by the respiratory activity of the product and the gas exchange through ... En savoir plus
Figure 1 shows a simplified scheme of a typical industrial steam methane reforming (SMR) reactor, which is a top-fired, packed-bed multi-tubular chemical reactor, consisting of a series of catalytic tubes arranged within a furnace. The tubes contain two adjacent catalytic sections filled ... En savoir plus
Electrochemical Impedance Spectroscopy (EIS) is a technique commonly used to investigate the properties of the electrode surface and the bulk electrolyte in an electrochemical cell [1]. An AC excitation signal is applied with a frequency range, typically from 0.01 Hz to 1 MHz, and the ... En savoir plus
The throwing power is an important criterion for the industrial use of an electrolyte in electroplating applications. Using the Electrodeposition Module and COMSOL Multiphyiscs® it is possible to simulate the thickness distribution for various electroplating geometries. For a realistic ... En savoir plus
Power-to-gas is an important area of research for reducing greenhouse gases and seasonal energy storage. Methane, with a Lower Heating Value of 50 MJ/kg, is already a commonly used gas, and its synthesis using green hydrogen production (electrolysis of renewable energy) is a remarkable ... En savoir plus
