A Cryopreservation‐Based Supply Chain Strategy for Extrusion Bioprinting in Space

Advanced Materials Technologies, EarlyView.
Extrusion bioprinting on crewed space platforms requires a bioink that stays functional along the logistic chain. Here, cells and biomaterial ink travel separately, the cells cryopreserved and the ink cold stored, and are combined only minutes before printing.

Linearized State-Space Model-Based Attitude Control for Rocket With Four Controllable Fins—Part 1-1: Basic Modeling and Identification

IEEE Access, 2023
In this study, we present, analyze, and validate a linear state-space model for a simplified rocket with four fins. The model is validated experimentally using a wind tunnel. The proposed model consists of two main elements: a rocket body and fins.
