Bioprinting in Microgravity

ACS Biomaterials Science & Engineering, 2023
Bioprinting as an extension of 3D printing offers capabilities for printing tissues and organs for application in biomedical engineering. Conducting bioprinting in space, where the gravity is zero, can enable new frontiers in tissue engineering.

The Evolution of Micromechanical Properties for Zr-Based Metallic Glass Induced by Laser Shock Peening

Frontiers in Materials, 2021
The micromechanical properties of Zr-based metallic glass (MG) induced by laser shock peening (LSP) were studied through the use of nanoindentation. The serrations in representative load-displacement (P-h) curves exhibited a transformation from stairstep-

On the growth dynamics of the cyanobacterium Anabaena sp. PCC 7938 in Martian regolith

npj Microgravity, 2022
The sustainability of crewed infrastructures on Mars will depend on their abilities to produce consumables on site. These abilities may be supported by diazotrophic, rock-leaching cyanobacteria: from resources naturally available on Mars, they could feed

Evaluation of Radiation Response in CoCrFeCuNi High-Entropy Alloys

Entropy, 2018
CoCrFeCuNi high-entropy alloys (HEAs) prepared by arc melting were irradiated with a 100 keV He+ ion beam. Volume swelling and hardening induced by irradiation were evaluated.

Asymptotic symmetries of scalar electrodynamics and of the abelian Higgs model in Hamiltonian formulation

Journal of High Energy Physics, 2021
We investigate the asymptotic symmetry group of a scalar field minimally-coupled to an abelian gauge field using the Hamiltonian formulation. This extends previous work by Henneaux and Troessaert on the pure electromagnetic case.

Quantum Bubbles in Microgravity [PDF]

Physical Review Letters, 2020
The recent developments of microgravity experiments with ultracold atoms have produced a relevant boost in the study of shell-shaped ellipsoidal Bose-Einstein condensates. For realistic bubble-trap parameters, here we calculate the critical temperature of Bose-Einstein condensation, which, if compared to the one of the bare harmonic trap with the same ...
