Metal‐halide perovskite solar cells offer high‐efficiency power for orbital missions but suffer from permanent proton‐induced degradation. This work identifies non‐ionizing energy loss (NIEL) as the primary driver of irreversible failure, inducing atomic displacements and microcracks in the high‐fluence regime. Through energy‐tuned mapping and scalable

The current work examines the dynamics of the stagnation point flow of an unsteady hybrid nanofluid (Fe2O3–Cu/H2O) across an inclined porous stretching surface. It considers heat transfer, second‐order slip, electrical field, heat source/sink, mixed convection, and magnetic field effects, as well as linear and nonlinear radiation.

Advancements and Challenges in Liquid Hydrogen Storage Tank Design for Maritime Applications
ABSTRACT In line with the Paris Agreement and the IMO's decarbonization goals, the shipping industry has begun to focus more intensively on adopting alternative fuels to reduce emissions. Among these, hydrogen has attracted considerable attention, with liquid hydrogen (LH2) offering advantages in energy density and storage volume over compressed gas ...

Unified monitoring of spacecrafts.
Im Rahmen dieser Arbeit wird eine neue Philosophie der Überwachung von Raumfahrzeugen vorgestellt: die Vereinigung der verschiedenen Arten von Überwachungstechniken, die während der verschiedenen Entwicklungsphasen eines Raumfahrzeuges verwendet werden. Die Anforderungen an dieses Monitoring Framework sind: - "Separation of Concerns" als Designprinzip,

Abstract Spaceflight induces altered physiology that has the potential to alter medication pharmacokinetics due to factors including gastrointestinal motility, fluid balance, circulatory dynamics, hormonal changes, and metabolic alterations. Here, we report the first pharmacokinetic analysis using blood samples during spaceflight.
