Quantitative Analysis of Topographic Crosstalk in DART‐ESM Arising from Feedback‐Loop‐Delay‐Induced Contact Stiffness Variations in Battery Materials

Small Methods, EarlyView.
Interpretation of Dual AC Resonance‐Tracking Electrochemical Strain Microscopy (DART‐ESM) signals is complicated by topography‐induced artifacts that distort measured responses. Using silicon with artificial trench structures as a reference, this study quantifies artifact magnitude and demonstrates that Cooling Cross‐Section Polishing (CCP) effectively

Woven Eutectic Lamellar Structures Lead to Ultrahigh Strength and Energy Absorption Capacity in Additively Manufactured Lattice Structures

Small Structures, Volume 6, Issue 5, May 2025.
Herein, AlCoCrFeNi2.1 is selected to produce lattice structures by selective laser melting. The as‐printed lattice structures consist of numerous colonies of nanosized eutectic lamellar structures which are bent and interwind with each other to form a woven microstructure. The unique microstructure leads to unprecedented effective metal strength, yield
