Dissipative layers for HSQ resist nanopatterning by E-beam lithography on insulating substrates, Couche dissipative pour nanostructuration de résine HSQ par lithographie électronique sur substrat isolant

Anne-Sophie Vaillard, Yves Deblock, Pascal Tilmant, David Guérin, Christophe Boyaval, Giuseppe Di Gioia

Dissipative layer is a key element in nanopatterning resist such as HSQ on insulating substrates. At IEMN we are currently investigating different strategies to avoid surface charging effect. Since a single top layer of Ge or Au leads to non-conform patterning, the first approach involves..., La couche dissipative est un élément clé dans les résines nanostructurées telles que le HSQ sur des substrats isolants. À l'IEMN, nous étudions actuellement différentes stratégies pour éviter l'effet de charge superficielle. Étant donné qu'une seule couche supérieure de Ge ou d'...

Ultra-Low-Power Neuromorphic Spike Detector for Large-Scale Neural Interfaces

Louis Regnacq, Hicham Lahrach, Anna Kobzar, Rédha Kassi, Pascal Mariot, A. Cappy, Christel Vanbesien, Alexis Vlandas, Christophe Loyez, Virginie Hoel

Neural interfaces are rapidly scaling, now featuring thousands of electrodes that record simultaneously. As channel counts grow, design constraints become increasingly stringent: implants must remain compact and ultra–low power while managing massive data streams. With data rates often exceeding...

Breaking through Microbial Defenses─Organic Acid-Based Deep Eutectic Solvents as a Neoteric Strategy in Bacterial Biofilms, Persister, and Fungal Control

Tomasz Swebocki, Aleksandra Kocot, Karolina Cieminska, Clovis Bortolus, Jérôme Muchembled, Meroua Mechouche, Justine Jacquin, Kamel Haddadi, Ali Siah, Boualem Sendid, Rabah Boukherroub, Magdalena Plotka

This study explores the adaptation of organic acid-based deep eutectic solvents (OA-DESs) as effective antimicrobial agents. Having already demonstrated their efficacy against planktonic bacteria in our previous research, herein we investigate their impact on more complex microbial forms, including...
