Switchable Magnonic Crystals Based on Spin Crossover/CrSBr Heterostructures
Advanced Materials, EarlyView.Multiscale modeling is employed to investigate the functionality of a light‐controlled, tunable magnonic crystal based on spin‐crossover Fe‐pz molecules integrated with a monolayer of CrSBr. Ab initio simulations confirm that the molecules remain functional on the CrSBr surface, while a semiclassical elastic model demonstrates that light‐induced ...

Engineering Strain‐Stiffening Granular Hydrogels for 3D‐Printed Tissue‐Mimicry
Advanced Materials, EarlyView.A 3D‐printable strain‐stiffening double‐network granular hydrogel (SDGH) enables independent, region‐specific tuning of toe (EToe) and heel (EHeel) moduli through control of microgel packing and network composition. This platform replicates tissue‐like nonlinear mechanics and allows fabrication of high‐fidelity, multilayered aortic valves with ...

Deformable mirror interferometric analysis for the direct imagery of exoplanets
, 2014 International audienceDirect imaging of exoplanet systems requires the use of coronagraphs to reach high contrast levels (10 −8 to 10 −11) at small angular separations (0.1). However, the performance of these devices is drastically limited by aberrations

Control Demonstration of a Thin Deformable In-Plane Actuated Mirror
, 2006 Current imaging satellites are limited in resolution and coverage area by the aperture size of their primary optical mirror. To get a large optical mirror into space, current launch weight and size restrictions must be overcome.

Development of a line module type of SiC deformable mirror
International Journal of OptomechatronicsIn this work, the complete development of a line module type silicon carbide (SiC) deformable mirror (DM) for adaptive optics (AO) is described. To eliminate the risk of fracture and misalignment during the simultaneous assembly of all actuators and the ...

Mechanical Stress Evolution in Polycrystalline Ge Thin Films Under MeV Ion Irradiation
Advanced Materials Interfaces, EarlyView.Irradiation of polycrystalline Ge thin films with 1.8 MeV Au ions alters residual stress through defect generation and lattice expansion. Increasing fluence drives progressive lattice disorder and eventual amorphization. Polycrystalline Ge resists amorphization longer than crystalline Ge, as grain boundaries facilitate defect diffusion, significantly ...

Optical correction of space-based telescopes using a deformable mirror system [PDF]
, 2016 Adaptive optics offer the potential to reduce the high cost and long lead time associated with manufacturing mirrors for spaced-based telescopes by allowing lighter materials to be substituted.
