Nanoscale Confinement Enhances Ultrafast Demagnetization
Advanced Science, EarlyView.Next generation spintronics may depend on successfully combining femtosecond spin dynamics with nanoscale device miniaturization. We address this by systematically studying the effect of nanoscale confinement on the femtosecond demagnetization of Iron. By combining ultrafast experiments sensitive to spins, charge carriers, and phonons, we uncover a nm ...

L’impact environnemental d’une habitation écologique
Revue des Énergies Renouvelables, 2010 Une maison écologique, désigne plus un concept qu’un type défini d’habitation. L’idée est de combiner les différents modes de chauffage, de ventilation, d’alimentation des appareils pour réduire massivement la consommation d’énergie, donc une ...

ENERGY COMMITMENT: A PLANNING OF ENERGY CARRIER BASED ON ENERGY CONSUMPTION
Electrical Engineering & Electromechanics, 2019 Purpose. Energy consumption is one of the criteria for determining the quality of life in a country. Continued supply of energy and the possibility of long-term access to resources require a comprehensive plan. One of the key issues in the field of energy planning is energy carriers.

Advanced Science, EarlyView.Unbalanced crystallization in mixed Sn‐Pb perovskites causes film defects and instability. CsPbI3 nanocrystals serve as nucleation seeds to regulate growth during slot‐die coating. Resulting solar cells retain 80% efficiency after nine thermal cycles. Operando GIWAXS confirms suppressed microstrain and lattice distortion, demonstrating that synergistic

Modèle d’échange d’énergie et de matière dans un four rotatif, incluant la combustion
Revue des Énergies Renouvelables, 2015 Cette étude a pour objet la modélisation d’un four rotatif d’une cimenterie par voie sèche. Le modèle repose sur la connaissance des cinétiques des réactions et sur la représentation macroscopique des écoulements par une cascade de réacteurs parfaitement

Advanced Science, EarlyView.Mixing method directly governs interface engineering and electrode morphology during the dry coating of all‐solid‐state battery cathodes. While high‐shear batch mixing yields poor electrode quality and lacks core–shell‐like features, continuous extruder mixing enables strong binder fibrillation and a core–shell‐like coating between the active material ...
