We present here an architectured band-gap metamaterial, filtering mechanical waves in specific ranges of frequencies which, by its very specific geometry, challenges the simulation of linear elasticity problems including such elements. This unorthodox behaviour can be described as a ... En savoir plus
Abstract: In order to study thermal conditions and air flows in an office room, 3D FEM simulation model was created. The room is enclosed by walls, floor and ceiling which thermal characteristics are specified by typical heat transfer coefficients and specific heat capacities. Space ... En savoir plus
We present the model of THz sensor based on thermoelectric Bi-Sb thin films. The model is based on an electromagnetic heating interface and combines radiofrequency and heat transfer modules. The studied frequency was 0.14 THz, irradiation power 30 mW. Films had a thickness of 150 nm and ... En savoir plus
A quantification of spatial and temporal evolution of laser-induced plume would enhance the comprehension of high speed imaging results and allow optimizing the acquisition conditions for the emission spectroscopy. What temperature and concentrations of the evaporating species are ... En savoir plus
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; ... En savoir plus
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 ... En savoir plus
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 ... En savoir plus
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 ... En savoir plus
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 ... En savoir plus
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 ... En savoir plus
