Microarchitectured materials are generally made of different compounds bound at the microscopic level using a periodic pattern. This results in a macroscopic material with new properties arising from each of the individual compound properties and the way the microarchitecture binds them. ... En savoir plus

Bitumen and asphalt durability is a critical concern in pavement engineering, particularly in the context of sustainability and carbon footprint reduction. Accurate prediction of the lifespan of these materials is essential for life cycle assessment (LCA) from cradle to grave. However, ... En savoir plus

Germanium-tin (Ge₁₋ₓSnₓ) microdisks are emerging as a promising platform for CMOS-compatible group-IV light sources due to their tunable direct bandgap and compatibility with silicon photonics. Their optical and electronic properties are critically influenced by tin concentration, strain ... En savoir plus

Deformation of food packaging materials due to internal pressure buildup during sterilization is a critical concern for packaging integrity and product safety, particularly in non-rigid containers like polypropylene (PP) trays for ready-to-eat meals. (Dutta et al., 2024b). Internal ... En savoir plus

The two most commonly used membrane profiles for sound reproduction of the high frequency audio band are the dome shape and the annular shape. The annular (also known as ring) shape has some different basic design features if compared to a dome with the same outer size. For example, ... En savoir plus

This study presents a model for simulating a subsurface pumped-hydro energy storage (battery) system. The model captures the coupling between fluid flow in an oil and gas type wellbore connected to a large hydraulic fracture embedded in a low-permeability reservoir. By integrating ... En savoir plus

This paper introduces a multiphysics simulation framework for examining the impact of mechanical vibrations on lithium dendrite formation in lithium-ion batteries. We connected the lithium-ion battery, solid mechanics, and phase field physics interfaces using a custom model in COMSOL ... En savoir plus

This paper describes the thermal and structural combined simulation on COMSOL Multiphysics® of a Microwave (MW) Fin Taper (FT) Spatial Power Combiner (SPC) Power Amplifier (PA), based on rectangular Waveguide (WG). In the SPC based PA's, the captured power is feeded by microstrip ... En savoir plus

Balanced armature (BA) micro-speakers, or receivers, are miniaturized loudspeakers used in hearing aid instruments, earphones, and hearables. A typical design of a BA receiver includes an armature (metal beam) with a coil wound around it. The armature tip is positioned exactly in the ... En savoir plus

As semiconductor devices continue to shrink and incorporate complex 3D architectures, conventional optical metrology faces limitations in resolving features smaller than the optical wavelength or those hidden beneath opaque layers. Ultrafast photoacoustic spectroscopy provides a ... En savoir plus
