Currently, interconnection solutions for electronic compounds involving an active side directed at substrates rely on metal brazing. Mechanical contacts are therefore rigid. For better adhesive reliability, a thermosetting resin is generally used as an underfill. This redistributes the thermomechanical constraints produced by differences in thermal expansion coefficients between the silicon chip and the substrate. The remarkable adhesiveness of gecko feet has long fascinated scientists. Their secret lies in a three-level hierarchical structure that supports low-intensity physical interactions, called the Van der Waals force. ​​

Résultat scientifique

Une équipe de BioMaps a suivi, en imagerie TEP, le métabolisme du glucose comme marqueur de l'impact cérébral du sevrage tabagique, ainsi que les effets d’un candidat-médicament prometteur pour le traitement d’un tel sevrage. En révélant la restauration de l’activité normale de la zone cérébrale associée au craving, ces résultats sont porteurs d’espoir pour l’arrêt du tabac chez l’Homme.

Scientific result

A BioMaps team has used PET imaging to monitor glucose metabolism as a marker of the cerebral impact of smoking cessation, as well as the effects of a promising drug-candidate for the treatment of such cessation. By revealing the restoration of normal activity in the brain area associated with craving, these results offer hope for smoking cessation in humans
