Advanced laboratory for testing plasma thrusters and Hall thruster measurement campaign
Nukleonika, 2016 Plasma engines are used for space propulsion as an alternative to chemical thrusters. Due to the high exhaust velocity of the propellant, they are more efficient for long-distance interplanetary space missions than their conventional counterparts.

Hierarchical Structure and Fabrication of Functionally Graded Biointerfaces in the Mussel Byssus
Advanced Materials Interfaces, EarlyView.The byssus is a fibrous protein‐based holdfast consisting of mechanically distinct interfaces, which mussels use to anchor their soft living tissue to hard seashore surfaces. Here, multiscale methodologies were used to elucidate the compositional and structural features underlying these functionally graded interfaces and how they are fabricated through

Advanced Materials Technologies, EarlyView.This work establishes a framework for high‐resolution printed interconnects by coupling e‐jet printing control, multilayer deposition, and sintering optimization. Ink properties and printing speed influence particle stacking, while different sintering atmospheres drive distinct microstructural evolution.

Dynamic Current Routing in Conductive Liquid Crystal Elastomers for Complex Deformation Actuators
Advanced Materials Technologies, EarlyView.This work introduces a novel actuation control strategy in which electrical stimulation generates localized Joule heating in conductive liquid crystal elastomer (LCE) surfaces, enabling complex 3D deformations from a single homogeneous surface without preprogramming.
