Magnetic nozzles for space plasma thrusters
, 2016 The magnetic nozzle (MN) is an appealing plasma acceleration technology that enables the electrodeless, contactless, and adaptable control of a plasma jet. Using a 2-D, two-fluid plasma model, the core physical principles that enable the operation of a propulsive MN are reviewed, including the key mechanisms involved in thrust generation, plasma ...

Advanced Materials Interfaces, EarlyView.Soft x‐ray absorption spectroscopy at the S L2,3 and Mo M2,3 edges reveals synthesis‐dependent electronic and structural order in MoS2. Bulk, exfoliated, and CVD samples show well‐resolved 2D features, while as‐deposited IJD films appear amorphous but crystallize into ordered 2H‐MoS2 upon moderate annealing, confirming IJD as a viable low‐temperature ...

Additively Manufactured Porous Ceramics as Tunable Dielectrics for Passive Temperature Sensing
Advanced Materials Technologies, EarlyView.Porous ceramic lattices, 3D‐printed from a multicomponent oxide ink, are integrated with LC resonators for passive wireless temperature sensing. By tuning porosity, the dielectric properties and RF response are engineered to produce distinct resonant frequency shifts with temperature. The results establish a structure‐driven approach to customizing the

Advanced Materials Technologies, EarlyView.We introduce an additively manufactured bioreactor with a perfusion flow system and integrated temperature and pH sensors for skeletal muscle tissue biofabrication. The bioreactor's performance was evaluated by assessing the viability, spreading of the myoblast cells in a printed scaffold, and contraction of the isolated murine musculi interossei ...
