Lever-Type Tuned Mass Damper for Alleviating Dynamic Responses
Advances in Civil Engineering, 2019 This study considers the structural vibration control by a lever-type tuned mass damper (LTMD). The LTMD has a constraint condition to restrict the motion at both ends of the lever.

Advanced Seismic Retrofitting with High-Mass-Ratio Tuned Mass Dampers
Soil Dynamics and Earthquake Engineering, 2023 Tuned Mass Dampers (TMDs) are traditionally employed in tall buildings to control displacements, typically featuring a low mass ratio. This study explores the potential of TMDs with significantly higher mass ratios for seismic retrofitting in existing civil structures, an area that remains largely unexplored.

Unusual Swelling Behavior of Hydrogels Modified with Spiropyran as Appendage or Crosslinker
Advanced Functional Materials, EarlyView.Not so innocent after all—spiropyran crosslinkers in methylenebisacrylamide‐crosslinked poly(acrylamide‐co‐acrylic acid) hydrogels increase crosslinking density, but also, counterintuitively, increase swelling. Charge complexation, cooperative chemo‐mechanical effects, and aggregation may explain these observations.

Molecular Cross‐Linking of MXenes: Tunable Interfaces and Chemiresistive Sensing
Advanced Functional Materials, EarlyView.In this study, Ti3C2Tx MXenes are initially functionalized using oleylamine ligands to form stable dispersions in an organic solvent. Subsequently ligand exchange with α,ω‐diaminoalkanes enables cross‐linking, along with precise tuning of interfaces. This structural control translates into tunable charge transport and responsive VOC sensing, showing ...
