Differential effects of isopropyl alcohol on glucose-induced insulin secretion in INS-1 and MIN6 cells

Valérie Pawlowski, Valérie Plaisance, Mathilde Lucas, Emerson Giovanelli, Chloé Derasse, Alexandre Barras, Amar Abderrahmani

Background Solvents such as isopropyl alcohol (IPA, propan-2-ol, also called isopropanol) can occasionally be used for drug solubilization in in vitro screening of antidiabetic agents. However, their potential to interfere with pancreatic β-cell function remains poorly characterized. Objective This...

Croissance de dendrites de polymère conducteur influencée par l'électroconvection et étude de leurs relaxations électrochimiques, Growth of Conducting Polymer Dendrites Influenced by Electroconvection and Study of Their Electrochemical Relaxations

Antoine Baron

En 2022, près de 62 millions de tonnes de déchets électroniques ont été produites à l'échelle mondiale, un chiffre en constante augmentation. Cette situation critique invite à repenser la manière dont les circuits électroniques sont conçus, la rigidité des dispositifs actuels les rendant..., In 2022, nearly 62 million tonnes of electronic waste were generated worldwide, a figure that continues to rise. This critical situation calls for a rethinking of how electronic circuits are designed, as the rigidity of current devices makes them rapidly obsolete and difficult to recycle. In nature...

Competing effects of charge-carrier and impurity scattering limiting phonon heat conduction in heavily-doped silicon

Raja Sen, Juan Carlos Acosta Abanto, Mélanie Brouillard, Séverine Gomès, Jean-François Robillard, Alessandro Ciavatta, Lorenzo Paulatto, Nathalie Vast, Jérôme Saint-Martin, Jelena Sjakste, Pierre-Olivier Chapuis

With respect to undoped semiconductors, thermal transport by phonons is limited by two additional mechanisms when doping increases: charge-carrier and impurity scattering. Previous works provided contradicting conclusions on the dominant doping-induced scattering mechanism in silicon. In this work...
