Metastable Polymers for Circular 3D Printing
Advanced Materials, EarlyView.3D‐printed polymers are usually permanent and hard to recycle. Here, metastable polymers are designed to fall apart on demand. A chemical trigger unzips the printed material back into its original building blocks within minutes at room temperature.

Virtual camera based a novel calibration without modeling
, 2007 Usually, the camera calibration and distortion correction are both considered as procedures with two steps: modeling, and then solving the parameters. In this paper, we introduced a virtual camera into camera calibration and presented a novel method for ...

Defect‐Templated Phase Engineering in Atomically Thin Metals
Advanced Materials, EarlyView.Graphene defects are transformed from passive imperfections into programmable templates for phase‐selective growth of atomically thin silver. Plasma‐generated boundary defects favor Ag(1), whereas sp3‐rich zero‐layer graphene promotes Ag(2). This defect‐directed intercalation links local graphene chemistry to crystalline phase, electronic structure ...

All‐Amyloid Functional Coacervates
Advanced Materials, EarlyView.This study introduces an all‐amyloid interfacial complex coacervate technique that employs charge‐mediated or functionalization‐assisted complexation of oppositely charged food protein‐derived amyloid nanofibrils to engineer functional soft constructs across multiple length scales.

Fast Hydrogel Micro‐Actuators Driven by Electric Fields
Advanced Materials, EarlyView.We report the fabrication of chemically programmable electroactuating microstructures through the first integration of two‐photon polymerization with electrically actuated gelatin methacrylate‐based hydrogels. By tailoring the charge of the polymer network, we demonstrate programmable polarity‐dependent bending, enabling microstructures that ...

A stepwise camera calibration method incorporating compensation for eccentricity error
Journal of Measurement Science and InstrumentationIn visual measurement, high-precision camera calibration often employs circular targets. To address issues in mainstream methods, such as the eccentricity error of the circle from using the circle’s center for calibration, overfitting or local minimum ...
