Impact of iodine-induced nonplanarity on the vibrational and electronic properties of a triphenylene derivative: A combined experimental and DFT study, Influence de terminaisons iodées sur la non-planaréité et les propriétés vibrationnelles et électroniques de dérivés triphénylènes: une étude expérimentale et théorique

Ahmed Hewail, David Guérin, Christophe Krzeminski, Eric Faulques, Nataliya Kalashnyk

We present a molecular study combining Raman, infrared, and UV–visible absorption spectroscopy with density functional theory (DFT) calculations to investigate triphenylene and its iodinated derivative, 1,5,9-triiodotriphenylene. The results provide a detailed comparison of their vibrational and…, Des études à l'échelle moléculaire de spectroscopie Raman, infra-rouge et absorption UV-visible, basées sur des simulations en théorie de la fonctionnelle de la densité sur le triphénylène et le dérivé iodé 1,6,9 triiodotriphénylène. Les résultats donnent une comparaison précise des propriétés…

Conflict-Aware Multimodal Fusion for Ambivalence and Hesitancy Recognition

Salah Eddine Bekhouche, Hichem Telli, Azeddine Benlamoudi, Salah Eddine Herrouz, Abdelmalik Taleb-Ahmed, Abdenour Hadid

Ambivalence and hesitancy (A/H) are subtle affective states where a person shows conflicting signals through different channels -- saying one thing while their face or voice tells another story. Recognising these states automatically is valuable in clinical settings, but it is hard for machines…

Pyrochlore nanomineralogy questions the immobility of niobium during tropical weathering

Quentin Bollaert, Mathieu Chassé, Nicolas Menguy, Corentin Le Guillou, Artur Bastos Neto, David Troadec, Laurence Galoisy, Georges Calas

The origin of the mobility of low-solubility elements such as niobium during supergene weathering remains elusive, despite growing evidence, especially in strongly weathered regolith. In the critical zone, the low mobility of these high field strength elements (HFSEs) is assigned to the resistance…

Bioelectrical memory effects behind fractional-order transients emulating synaptic plasticity in brain-inspired electrochemical dendrites

Antoine Baron, Sébastien Pecqueur, Enrique Balaguera

Understanding and reproducing the brain’s ability to store and process information remains a central challenge in neuromorphic engineering. Here, we identify the physical origin and provide a phenomenological interpretation of memory effects underlying synaptic-like plasticity, realized in brain-…
