Effectively storing hydrogen in solid form using metal hydrides requires careful attention to thermal management challenges due to the exothermic nature of hydrogen absorption in metal hydrides [1], [2]. The generated heat during this process must be efficiently removed to achieve ... En savoir plus
Traffic noise pollution has represented a significant challenge for modern societies, requiring the development of innovative noise mitigation strategies. In the last decades, intensive research has been developed into the design and evaluation of noise barriers but there still lacks a ... En savoir plus
Foundation scour is a major cause of bridge collapse worldwide (e.g., Kirby et al., 2015). Indeed, several studies have demonstrated its detrimental effects on the soil-structure system, both in terms of the foundation capacity and stiffness (e.g., Foti et al., 2023). Furthermore, the ...

Obtaining a good coverage of Digital Audio Broadcasting (DAB) service, in the 200 MHz band, in motorway tunnels is quite a challenging task. Recently, Rai Research Centre (CRITS) has been involved in investigating alternative (and cheaper) solutions than those adopted so far (radiating ... 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
In structural optimization, the norm has long been to use maximum stress or compliance as objectives to be minimized. However, probabilistic quantities, such as the probability of failure, offer a fresh and powerful alternative. These quantities are inherently dimensionless, confined to ... En savoir plus
A Solid Oxide Fuel Cell (SOFC) can convert the chemical energy of a fuel (H2-rich gas mixture [1] or syngas [2, 3] or biogas [4]) in electric and thermal energies with high electric efficiency. It is composed of two porous gas diffusion electrodes and an electrolyte (Figure 1). The fuel ... En savoir plus
The goal of this study is to exploit the phase change in vanadium dioxide (VO₂) for optical sensing. Infrared (IR) sensing is of paramount interest for next-generation Internet of Things (IoT) devices. Phase change materials (PCMs) are expected to enable low-energy consumption sensors, ...

Particle In Cell (PIC) simulation tool for the simulation of 2.45GHz ECR ion source was developed tanks to Comsol Multiphysics RF module capability to compute electromagnetic field propagation imposing a tensorial permittivity with real and complex parts. A tensorial description is ... En savoir plus
The process-induced deformation in the DED fabricated part is a critical issue to the scaling of the technology. Currently, an inefficient and expensive experiment trial-and-error approach is utilized to tackle this issue, however it is not feasible for large parts. Researchers have ... En savoir plus
