Exploring Math Moments: Middle-schoolers’ Phases of Problem-solving, Executive Functions in Practice, and Collaborative Problem Solving

open access: yesFrontline Learning Research
Collaborative problem solving (CPS) has been shown to both engage and benefit students’ learning of mathematics. However, there is evidence that group work is not always easy to facilitate, in part because educators lack details about learners ...

Fabrication‐Directed Entanglement for Designing Chiral and Anisotropic Metamaterial Foams

open access: yesAdvanced Engineering Materials, EarlyView.
This work introduces fabrication‐directed entanglement (FDE), combining viscous thread printing and topology optimization to program entangled foams with spatially patterned stiffness. By tuning coil density, FDE enables anisotropy, programmable Poisson's ratio, and chirality in foams.

Scalable Robotic Laser Texturing of Tilted Microanchors for Direction‐Independent Metal–Polymer Joining

open access: yesAdvanced Engineering Materials, EarlyView.
A robot‐assisted laser processing method is proposed that enables the formation of surface‐tilted microanchors on metal substrates to improve metal–polymer joining. Using a six‐axis robotic platform, the laser beam's incidence angle, scanning path, and interline pitch can be precisely controlled, allowing the deliberate overlap of heat‐affected zones ...

Numerical Model and Experimental Validation of Composite Metal Foam in Protecting Carbon Steel Against Puncture

open access: yesAdvanced Engineering Materials, EarlyView.
The puncture prevention and energy absorption performance of composite metal foam (CMF) are studied experimentally and numerically for hazardous materials transportation protection. The numerical model implementing air within the CMF (nonhomogeneous model using fluid cavity technique) predicts puncture more accurately compared to the homogeneous CMF ...
