Fabrication of Sustainable 3D Printed Anisotropic Bonded Magnets Using Recycled Nd–Fe–B Powder and Low CO2 Footprint Polyamide 12

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 1, January 2026.
Researchers develop a sustainable way to 3D‐print high‐performance Nd–Fe–B magnets using recycled material from end‐of‐life magnets. By combining anisotropic recycled powder with a low‐carbon polyamide matrix, they achieve complex shapes and over 60% better magnetic performance than previous recycled options, offering a promising path toward a more ...

Analysis of Vibration‐enabled Dynamic Dispensing of Surrogate Energetic Powders

open access: yesPropellants, Explosives, Pyrotechnics, Volume 51, Issue 1, Page 127-143, January 2026.
ABSTRACT Energetic materials have uniquely high energy densities and rapid release rates that provide solutions to a wide range of engineering problems, such as propulsion and demolition. The sensitivity of energetics is dependent on many factors, including microstructure and sources of initiation (i.e., mechanical insult, thermal, and electrostatic ...
