Proton exchange membrane fuel cells (PEMFCs) are promising energy converters, offering both sustainability and efficiency. Achieving optimal performance, however, requires a deep understanding of the underlying cause-effect relationships within the functional layers. One effective ... En savoir plus

As part of our primary research focus, we explore the phenomenon of non-radiative resonance energy transfer (RET) between a pair of dipoles positioned within a hyperbolic metamaterial (HMM). Our investigation reveals that the presence of an HMM can fundamentally alter these non-radiative ... En savoir plus

Due to climate change impacts and the worsening growth conditions of Norway spruce (Picea abies) the species composition of European forests is being diversified, incorporating more hardwoods as well as drought-resistant softwood species, such as Douglas-fir (Pseudotsuga menziesii). As a ... En savoir plus

In this simulation, we aim to comprehend the origin and mechanism of the warpage phenomenon in patterned silicon wafers, which are key components in the field of microelectronics. This issue can become more pronounced in the presence of high global density of the patterns and can lead to ... En savoir plus

Surface plasmon polaritons (SPPs) are electromagnetic waves that travel along a metal–dielectric or metal–air interface, practically in the infrared or visible-frequency. The term "surface plasmon polariton" explains that the wave involves both charge motion in the metal ("surface ... En savoir plus

The acid-disassociation of surface groups generates the surface charge that drives fundamental nanoscale ion transport behaviors, such as ion current rectification in nanopores. Ion current rectification can be utilized for high sensitivity label-free sensors. The disassociation of ... En savoir plus

INTRODUCTION The coupling of the Schrödinger and Maxwell equations allows to predict the self-generated electromagnetic (EM) field for a quantum charged particle moving in a domain. Such problem is really challenging, and it must be investigated in order to simulate the behavior of a ... En savoir plus

In applications like nuclear reactors or particle accelerators, mechanical components near a source of radiation develop radiation damage. This typically means a change in tensile properties and fracture toughness, which depends on the radiation dose (commonly measured in ‘displacements ... En savoir plus
