3D‐Printable Near‐Infrared‐Responsive Microscale Cantilever made of the Composite Consisting of Ceramic Particles and Graphene Flakes

Advanced Engineering Materials, EarlyView.
A near infrared‐responsive microscale cantilever is developed using a 3D‐printable composite based on photocurable resin consisting of sepiolite and graphene flakes. The material absorbs 1064 nm light, causing shape transformation with an average displacement of 1.3 mm in 1.7 s. Displacement is measured via video recording.

Development and Preliminary In Vivo Study of 3D‐Printed Bioactive Glass Scaffolds with Trabecular Architecture

Advanced Engineering Materials, EarlyView.
This study reports the fabrication of trabecular bioactive glass scaffolds (composition “1d”: 46.1SiO2‐28.7CaO‐8.8MgO‐6.2P2O5‐5.7CaF2‐4.5Na2O wt%) through vat photopolymerization and the relevant results from mechanical testing and in vivo implantation procedures in rabbit femora, showing great promise for bone tissue engineering applications.

Traceable measurements of electrical impedance

IEEE Instrumentation & Measurement Magazine, 2015
Scientists and engineers from different backgrounds share the need for measurement of electrical impedance and related quantities. Equivalent lumped resistance, capacitance, or inductance are common parameters in the characterization, specification, and design of electrical and electronic components.

Multimode Adaptive Thermoregulation Enabled by Shape Morphing and Radiative Cooling Porous Polyurethane

Advanced Engineering Materials, EarlyView.
A shape‐morphing, porous polyurethane film combines passive radiative cooling with folding to deliver multilevel heating‐and‐cooling control. High solar reflectance and midinfrared emissivity keep surfaces up to 3.5 °C cooler in direct sunlight, while photothermal triggering folds the film to absorb solar heat.
