Encapsulating Zinc Powder in MXene/Silk Scaffolds with Zincophilic‐Hydrophobic Polymer for Flexible Zinc‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This work develops flexible zinc‐ion batteries (FZIBs) using a zincophilic/hydrophobic polymer (thermoplastic polycarbonate‐based polyurethane, TPCU) to protect Zn powder anodes and MXene/Silk (MXS) as flexible current collectors. The designed TPCU‐ZnP@MXS structure enables uniform Zn deposition, yielding dendrite‐free anodes with stable cycling ...

Mechanical Properties of Architected Polymer Lattice Materials: A Comparative Study of Additive Manufacturing and CAD Using FEM and µ‐CT

open access: yesAdvanced Functional Materials, EarlyView.
This study examines how pore shape and manufacturing‐induced deviations affect the mechanical properties of 3D‐printed lattice materials with constant porosity. Combining µ‐CT analysis, FEM, and compression testing, the authors show that structural imperfections reduce stiffness and strength, while bulk material inhomogeneities probably enhance ...

Biotite effect on the anisotropic properties of gneiss in Eastern Himalayas, China

open access: yesJournal of Rock Mechanics and Geotechnical Engineering
Intact rocks with layered microstructures, such as gneiss, exhibit strong anisotropy. Although anisotropy in the macroscopic strength of gneiss has been widely reported, the role of microstructures in tensile mechanics remains largely unclear.
