Full‐Field Damage Monitoring in Architected Lattices Using In situ Electrical Impedance Tomography

Advanced Functional Materials, EarlyView.
In situ electrical impedance tomography (EIT) turns 3D‐printed, CNT‐infused architected lattices into full‐field damage‐imaging systems. Tunable Voronoi‐based geometries act as active sensing architectures, enabling conductivity maps to detect early‐stage damage and localise sequential ligament fracture before catastrophic failure.

Analog Classification of Human Hand Gestures Exploiting Dendritic Integration With an Organic Artificial Soma

Advanced Functional Materials, EarlyView.
An organic neuromorphic architecture for the classification of human motor behavior is presented and validated. It performs somatic integration by linearly combining the activity from three muscles. An investigation of synaptic weights is presented and discussed in relationship with the classification performance.

Particle‐Level ZrO2 Atomic Layer Deposition Enables Fast‐Cycling and Long‐Life Graphite Cathodes for Dual‐Ion Batteries

Advanced Functional Materials, EarlyView.
A spatial location of atomic layer deposition (ALD)‐derived ZrO2 coatings is demonstrated to be a critical design parameter for stabilizing graphite cathodes in DIBs. Direct particle‐level ALD (PALD) screening of representative metal oxides identified ZrO2 as the coating that provides the most favorable balance of high‐rate capability and interfacial ...

XTRUDE: A Process‐Informed Framework for High‐Fidelity Analysis of Hydrogel Extrusion

Advanced Functional Materials, EarlyView.
Extrusion performance emerges from the interplay between material properties and processing conditions. XTRUDE (eXTrusion Rheology for Understanding and Defining Extrudability) recreates the extrusion environment with in situ pressure and temperature sensing, enabling characteristic pressure signatures to quantify extrusion‐specific phenomena and ...

In vitro evaluation of the failure of rotary instruments Mtwo® y ProTaper®

Acta Odontológica Colombiana, 2013
Introduction: Successful treatment depends on the endodontic removal of microorganisms with chemomechanical preparation. Rotary NiTi instruments offer greater flexibility and efficiency in the court, but the failure of these can occur unexpectedly by ...

Molecularly Dissipative Liquid Crystal Elastomer Foams for Impact and Vibration Attenuation

Advanced Functional Materials, EarlyView.
Liquid crystal elastomer foams integrate cellular deformation with mesogen reorientation to create a dual‐scale energy dissipation mechanism. Progressive pore collapse absorbs mechanical loads, while stress‐induced mesogen reorientation provides additional damping, resulting in reduced impact transmission and broadband suppression of vibrational ...
