The main goal of this Ariadna study was to determine the radiation hardness of potential future space processors. The AR0 test-chip was used to study the impact of SEUs and SETs on different versions of a hardened processor on UTBB-FDSOI 28nm technology, including DICE flip-flops, and three different hardening level of combinational logic.

The mushroom-forming fungi Pleurotus ostreatus (PO), Trametes versicolor (TV) and Schizophyllum commune (SC) are known to effectively colonise organic material. These fungi were grown on the aquatic fern Azolla filiculoides (AF), the fastest growing plant on Earth, and that can fix its own nitrogen. SC showed the best growth on AF. Therefore, growth of this fungus was determined under microgravity conditions and high radiation dosage (up to 200 Gy) and related to melanin production.

This study aimed to develop a framework for studying the effects of spacetime curvature on the propagation of quantum states of light, and to compare them with the propagation of classical light. When distributing entangled photon pairs through a gravitational potential, the effect of spacetime curvature on the properties of quantum states can become significant. This could be relevant for plans to use satellites for global quantum key distribution.

Motivation:
To provide a proof-of-concept demonstration of light rectification in a nano-rectenna as an alternative energy conversation process to semiconductor solar cells based on the photovoltaic effect. For space this alternative energy conversion process could enable applications under different environmental conditions (e.g. temperature ranges, radiation) and offer the advantage of higher theoretical conversion efficiency.
Methodology:
To provide a proof-of-concept demonstration of rectennas working at high frequencies through the development of:
