From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices

open access: yesAdvanced Engineering Materials, EarlyView.
Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.

Eco‐Friendly Aqueous Polymeric Binders for High‐Performance Graphite Anodes: Structure–Property Insights for Lithium‐Ion Batteries

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Polyvinylidene fluoride (PVdF) is commonly used as a binder material in the preparation of anode or cathode electrode slurries for commercial Li‐ion batteries (LIBs). High‐cost PVdF binder generally requires the use of toxic and environmentally unfriendly N‐methyl‐2‐pyrrolidone (NMP) as a solvent for dissolution.
