Searching for Topological Semi‐Complete Bandgap in Elastic Truss Lattices

open access: yesAdvanced Science, EarlyView.
Ideal gapless nodes within clear bandgaps remain elusive in elastic systems, where degeneracies always hide in trivial bulk bands due to intricate modes. The work proposes a topological semi‐complete bandgap (exhibits a complete bandgap except for the inevitable topological degenerate points) in a 3D elastic truss lattice by tuning a supporting rod ...

Enhancing Interlayer Bonding in DLP‐Printed Piezoelectric Ceramics via Controlled Secondary Curing for High Piezoelectric Performance

open access: yesAdvanced Science, EarlyView.
This study introduces an interfacial secondary curing strategy to overcome interlayer delamination in DLP‐printed PZT ceramics. Precise exposure time modulation enhances interfacial bonding via unsaturated bond conversion and stress control. Printed components exhibit a high piezoelectric coefficient (d33 = 516 pC·N−1) and exceptional sensing ...

Synergistic Ultrasound‐Photo Enhancement of Ferroelectric Catalysis via Molecular Multiferroics

open access: yesAdvanced Science, EarlyView.
This work demonstrates the first use of molecular multiferroic DEFM‐FeBr4 as an efficient catalyst for alkane oxidation using O2. Synergistic ultrasound and light activation enable outstanding performance, achieving a TON of 1942—29 times higher than BaTiO3. Mechanistic insights reveal ferroelectric polarization enhances charge separation. The approach
