Establishment of “Structure‐Efficiency” Relationship in Ultra‐High Purity Metal Systems: Multi‐Scale Analysis of Tellurium as a Prototype

open access: yesAdvanced Science, EarlyView.
By combining theoretical calculations with zone refining experiments, the quantitative relationship between purification efficiency and microstructure can be established. This multi‐scale investigation establishes a comprehensive framework for understanding the “structure‐efficiency” relationship in ultra‐high‐purity metals, providing theoretical ...

Efficient Exothermic Press toward Ultrafast and Scalable Manufacturing of Complex Polymer Composites

open access: yesAdvanced Science, EarlyView.
Exo‐press frontal polymerization is a rapid, low‐energy process to produce multiscale fiber‐reinforced polymer composites at high fiber volume fractions. By leveraging localized heat, along with a hybrid monomer system, the reaction front cures parts within a minute and forms a copolymer network.

Bio‐Inspired Stored Magnetic Energy Actuator with Transient Triggering and Programmable Logic

open access: yesAdvanced Science, EarlyView.
A bio‐inspired magnetic energy actuator achieves 1.6 m/s transient release—three orders faster than conventional systems—via direct ink writing printed NdFeB/Polydimethylsiloxane composites and environmental locks; biomimetic AND‐gate logic enables sequential cue recognition (e.g., “temperature → rainfall”).

Direct‐Write Printed Contacts to Layered and 2D Materials

open access: yesAdvanced Electronic Materials, EarlyView.
It is demonstrated that direct‐write printing is a viable method to fabricate devices on different 2D and layered materials yields Ohmic contacts in a single step, as compared to multi‐step lithography processes which often yield poor contacts. Printed devices perform exceedingly well with gating, temperature cycling, and in magnetic fields.
