Vers une modélisation avancée de la propagation des fissures dans les matériaux anisotropes grâce à la fabrication additive par dépôt de fil fondu
Les matériaux anisotropes gagnent en importance dans l'industrie, sous l'impulsion de nouvelles applications et de préoccupations environnementales, qu'il s'agisse de la construction en bois, des monocristaux pour les applications photovoltaïques ou les turbines...
Tethon 3D Acquires Fortify IP to Target RF and Defense Applications
Tethon 3D has acquired Fortify’s advanced materials intellectual property. Fortify wanted to bring fiber-reinforced vat-polymerized parts to market before pivoting to electronics and later to RF applications. This got them $12 million in funding from Lockheed Martin,...
ETL & NXGSAT Demonstrate Interoperable End-to-End 5G NTN Solution Powered by DIFI
NXGSAT, in partnership with ETL Systems, has successfully demonstrated an interoperable, fully productised 5G non-terrestrial network (NTN) solution, combining NXGSAT’s software-defined 5G NTN user equipment (UE) modem with ETL’s GENUS Digital platform, integrated...
A Novel Ceramic-Liquid Alloy Lattice Metastructure for Thermal Protection in Aerospace Applications
Extreme thermal shock in space exploration poses a critical threat to orbital spacecraft, as conventional thermal protection structures cannot concurrently resist concentrated thermal effects under shock and ensure efficient heat dissipation during routine operation....
Multi-View Camera-Based UAV 3D Trajectory Reconstruction Using an Optical Imaging Geometric Model
In low-altitude complex environments, accurately reconstructing the three-dimensional (3D) flight trajectories of small unmanned aerial vehicles (UAV) without onboard positioning modules remains challenging. To address this issue, this paper proposes a multi-view...

La Russie déploie tardivement une constellation de satellites pour remplacer Starlink
Très gênée sur le front ukrainien par l’absence d’un système de communication offrant haut débit et chiffrement incassable, l’armée russe place ses espoirs dans Rassvet, une constellation qui ne sera pas opérationnelle avant deux ans. La Russie a commencé le...
Your Guide to Optical Materials
Optical materials power the magic of modern photonics, from smartphone cameras to global fiber-optic networks, by precisely shaping light's transmission, reflection, absorption, refraction, and emission in lasers, sensors, and beyond. Selecting the right optical...
Diamonds in Defense: Northrop Grumman’s Secret to Next-Gen Power and Protection
Groundbreaking research is underway at Northrop Grumman’s Microelectronics Center (NGMC) which is reshaping physicists’ understanding of diamonds, positioning them as the next-generation material used in manufacturing microelectronics. Today, successful tests are...
L’Allemagne s’intéresse aussi au drone de combat collaboratif australien MQ-28 Ghost Bat
l y a quelques jours, dans le cadre de son partenariat conclu avec l’américain Kratos en 2025, Airbus Defence & Space a fait savoir qu’il était en train de préparer le premier vol d’un drone de combat collaboratif [CCA] XQ-58 «Valkyrie» équipé de son système de...
