Modification of MnFe2O4 surface by Mo (VI) pyridylimine complex as an efficient nanocatalyst for (ep)oxidation of alkenes and sulfides

N. Bouzari, A. Bezaatpour, B. Babaei, M. Amiri, Rabah Boukherroub, Sabine Szunerits

In this current paper, we report a new type of heterogeneous molybdenum (+6) complex, prepared by covalent grafting of cis-dioxo‑molybdenum (VI) pyridylimine complex on the surface of MnFe2O4 nanoparticles (NP) and characterized using various physicochemical techniques. The recyclable prepared...

Diaryl Sulfide Derivatives as Potential Iron Corrosion Inhibitors: A Computational Study

Morad El-Hendawy, Asmaa Kamel, Mahmoud Mohamed, Rabah Boukherroub, Jacek Ryl, Mohammed Amin

The present work aimed to assess six diaryl sulfide derivatives as potential corrosion inhibitors. These derivatives were compared with dapsone (4,4′-diaminodiphenyl sulfone), a common leprosy antibiotic that has been shown to resist the corrosion of mild steel in acidic media with a corrosion...

Stability of the threshold voltage in fluorine-implanted normally-off AlN/GaN HEMTs co-integrated with commercial normally-on GaN HEMT technology

Florent Albany, François Lecourt, Ewa Walasiak, N. Defrance, Arnaud Curutchet, Hassan Maher, Yvon Cordier, Nathalie Labat, Nathalie Malbert

Fluorine ion migration in normally-off AlN/GaN HEMTs fabricated by fluorine ion plasma implantation technology is evidenced. Devices under test are co-integrated into the OMMIC commercial D006GH/D01GH MMIC process, providing fluorine-free normally-on HEMTs. Gate reverse bias step-stress experiment...

Sortilin-derived peptides promote pancreatic beta-cell survival through CREB signaling pathway

Guillaume Daziano, Nicolas Blondeau, Sophie Béraud-Dufour, Amar Abderrahmani, Carole Rovère, Catherine Heurteaux, Jean Mazella, Patricia Lebrun, Thierry Coppola

Deterioration of insulin secretion and pancreatic beta-cell mass by inflammatory attacks is one of the main pathophysiological features of type 2 diabetes (T2D). Therefore, preserving beta-cell mass and stimulating insulin secretion only in response to glucose for avoiding the hypoglycemia risks,...

High-Q silicon nitride drum resonators strongly coupled to gates

Xin Zhou, Srisaran Venkatachalam, Ronghua Zhou, Hao Xu, Alok Pokharel, Andrew Fefferman, Mohammed Zaknoune, Eddy Collin

Silicon nitride (SiN) mechanical resonators with high quality mechanical properties are attractive for fundamental research and applications. However, it is challenging to maintain these mechanical properties while achieving strong coupling to an electrical circuit for efficient on-chip integration...

Modeling and experimental analysis of the mass loading effect on micro-ionic polymer actuators using step response identification

Iman Dadras, Sofiane Ghenna, Sébastien Grondel, Eric Cattan, Jaan Raik, Alvo Aabloo, Saoni Banerji

This paper presents a linear electrochemomechanical model for microscale ionic actuators. A frequency-domain approach is used to facilitate model interpretation, simplify model application, and accelerate the generation of actuator-specific models. A system comprising a micro PEDOT:PSS/PEO actuator...

Development of broadband high-frequency piezoelectric micromachined ultrasonic transducer array

Xu-Bo Wang, Le-Ming He, You-Cao Ma, Wen-Juan Liu, Wei-Jiang Xu, Jun-Yan Ren, Antoine Riaud, Jia Zhou

Piezoelectric micromachined ultrasonic transducers (PMUT) are promising elements to fabricate a two-dimensional (2D) array with a pitch small enough (approximately half wavelength) to form and receive arbitrary acoustic beams for medical imaging. However, PMUT arrays have so far failed to combine...

Bias-dependence of surface charge at low temperature in GaN self-switching diodes

E. Perez-Martin, I. Iniguez-De-La-Torre, T. Gonzalez, Christophe Gaquière, J. Mateos

In this work, with the help of a semi-classical two-dimensional Monte Carlo (MC) simulator, we study the DC current-voltage curves of Self-Switching Diodes (SSDs) fabricated on an AlGaN/GaN heterostructure from 100 K up to room temperature. Due to the very narrow channel of the SSDs, the presence...

Bowl-shaped ZnO ultrasonic transducer for photoacoustic/ultrasonic multimode microscopy

J. Zhang, D. Zhao, D. Li, F. Tian, Wei-Jiang Xu, X. Wu

A bowl-shaped ultrasonic transducer is proposed for photoacoustic/ultrasonic multimode microscopy. The transducer uses zinc oxide (ZnO) as the piezoelectric material, which has a better electromechanical coefficient than flexible PVDF polymer and ensures the detection sensitivity. The ZnO film is...
