Changement d'instance donc nouvelle #introduction
Je suis maitresse de conférence en chimie (précédemment en physique) à l'Université de Rennes. Je travaille sur les matériaux ferroélectriques, en particulier sur les aspects cristallographie et caractérisation électriques macro et nano (AFM).

Je publie aussi sur mes loisirs (crochet, rien depuis longtemps) et ma vie en général.
Je publie en français et en anglais

Powering Next-Gen Electronics: Scientists Find High-Performance Alternative to Conventional Ferroelectrics

A study by Rice University identifies a high-performance alternative to traditional ferroelectrics. Lighting a gas grill, getting an ultrasound, using an ultrasonic toothbrush ⎯ these actions involve the use of materials that can translate an electric voltage into a change in shape and vice versa.

#Scientists have found the secret behind a property of solid materials known as #ferroelectrics, showing that #quasiparticles moving in wave-like patterns among vibrating #atoms carry enough heat to turn the material into a thermal switch when an #electrical field is applied externally.

A quasiparticle that can transfer heat under electrical control

Scientists predict and confirm theoretical property of ferroelectrics

I have spent a little time familiarising with the accepted behaviour, so it is now time for a proper introduction.

I am a lecturer in material science at the university of Dundee 🏴󠁧󠁢󠁳󠁣󠁴󠁿. I teach in both physics and mechanical engineering.
My research focuses on the relationship between electronic properties and the atomic structure of ferroelectrics.

I am also an avid hiker and crocheter
