Updated software improves slicing for large-format 3D printing
For decades nuclear physicists have tried to learn more about which elements, or their various isotopes, are “magic.” This is not to say that they display supernatural powers. Magic atomic nuclei are composed of “magic” numbers of protons and neutrons—collectively called nucleons—such as 2, 8, 20, and 28.
Increased power densities in electronics will require more efficient heat sinks, and additive manufacturing combined with a simple thermal annealing process could help designers meet that goal. A team that includes Oak Ridge National Laboratory’s Tong Wu reported that while a 3-D printed aluminum alloy heat sink equaled or measured 10 percent worse than those manufactured conventionally, after the treatment the performance gap vanished.
Production run spot checks of materials for lithium-ion batteries and fuel cells could be a thing of the past because of a process developed at Oak Ridge National Laboratory. The infrared/thermal nondestructive evaluation technique invented by a team led by David Wood examines key parameters such as porosity and thickness of the coating in real time without destroying product.
Since the discovery of high-temperature superconductors — materials that can transport electricity with perfect efficiency at or near liquid nitrogen temperatures (minus-196 degrees Celsius) — scientists have been working to develop a theory that explains their essential physics.
A multi-institution team led by Oak Ridge National Laboratory’s Gaute Hagen used computation to corroborate experimental findings throwing calcium-52’s status as a magic isotope into question.
Researchers at Oak Ridge National Laboratory are using bamboo fiber in 3-D printing experiments to determine whether bio-based feedstock materials are feasible in additive manufacturing.
