Electricity-driven selectivity in the photocatalytic oxidation of methane to carbon monoxide with liquid gallium-semiconductor composite

My Nghe Tran, Alina Skorynina, Ahmed Addad, Ali Fadel, Karima Ben Tayeb, Lydia Karmazin, Louis Thomas, Massimo Corda, Yevkeni Wisse, Evgeny Vovk, Andrei Khodakov, Bruno Grandidier, Vitaly Ordomsky

Metal co-catalysts in oxide semiconductors are essential to enhance photocatalytic reaction, but the selectivity is often low due to the conversion of the target molecules as more reactive in comparison with the reagents. Here, we explore the influence of electricity on the activity and selectivity...

Comparative Study of Real-Time Beamforming Techniques for Railway Communication Systems in LoS and NLoS Scenarios

Semah Mabrouki, Iyad Dayoub, Marion Berbineau

This paper presents a comparative study of real-time beamforming techniques for railway communication systems in Line-of-Sight (LoS) and Non-Line-of-Sight (NLoS) scenarios. Using the 3GPP TR 38.901 channel model, initial machine learning (ML)-based beam prediction solutions are evaluated, and...

Joint Sub-6 GHz and mm-Wave V2I MIMO Radio Channel Characterization

Pascal Pagani, Pierre Laly, Eric Simon, Valentin Picquet, Raffaele d'Errico, Davy Gaillot

The development of 5G and 6G networks has driven to the development of two key technologies: massive Multiple-Input Multiple-Output (mMIMO) and access to millimeter wave (mm-Wave) frequencies [1], and the concept of distributed cell-free massive MIMO (CF-mMIMO), primarily targeting sub-6GHz...
