An Atomic-Level Bimetallic MOF Platform Overcoming the Stability-Performance Tradeoff for Laser Propulsion. [PDF]

open access: yesAdv Mater
This work introduces an atomic‐level engineered bimetallic MOF Platform that resolves the inherent trade‐off between environmental stability and propulsion efficiency. By integrating robust Fe‐O bonds for hydrolysis resistance and enabling d‐orbital charge transfer (Fe3+→Cu2+) for enhanced photothermal conversion, the design achieves a highly durable ...

A Dynamic Testbed for Nanosatellites Attitude Verification [PDF]

open access: yesAerospace, 2020
To enable a reliable verification of attitude determination and control systems for nanosatellites, the environment of low Earth orbits with almost disturbance-free rotational dynamics must be simulated. This work describes the design solutions adopted for developing a dynamic nanosatellite attitude simulator testbed at the University of Bologna.
