Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

Advanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Space and Security

Η ανθρώπινη παρουσία στο διάστημα παρουσιάζει τόσο συναρπαστικές ευκαιρίες όσο και σημαντικές προκλήσεις ασφαλείας. Αυτή η διατριβή εξετάζει το εξελισσόμενο τοπίο ασφαλείας που περιβάλλει τις διαστημικές δραστηριότητες. Αναλύει τους κινδύνους που συνδέονται με τον αυξανόμενο αριθμό δορυφόρων σε τροχιά γύρω από τη Γη, συμπεριλαμβανομένων πιθανών ...

Triply‐Twinned Metamaterials: Unraveling the Mechanics and Failure Pathways Through High‐Resolution XCT

Advanced Materials, EarlyView.
Triply‐twinned architected lattices transform deformation from bending to stretching of struts, delivering up to threefold increases in stiffness and strength across polymeric and metallic systems. High‐resolution synchrotron XCT and image‐based simulations reveal how meta‐grain architecture, defects, and AM build orientation govern failure pathways ...

Adaptive security in smart spaces: Dissertation

, 2013
Smart spaces - like smart homes, smart offices and smart cities - exploit various resources in order to offer enriched services and information for the end users. Achieving security in such a dynamic and heterogeneous environment with pre-defined and static security mechanisms is a challenging task.
