Verification and experimental validation of neutral atom beam source produced by L-PBF

open access: yesJournal of Physics Communications
We report validation tests of a calcium atomic-beam source fabricated via Laser Powder Bed Fusion (L-PBF). The surface quality and elemental composition of the printed component were quantitatively assessed, allowing us to establish reference parameters ...

Overcoming Processability Limitations in Al6082 Alloy by Using Laser Powder Bed Fusion of Aluminum Matrix Composites with Titanium Carbide/Silicon Carbide Reinforcements

open access: yesMetals
The use of aluminum alloys in aerospace is limited by their poor weldability, making many incompatible with additive manufacturing (AM) processes like powder bed fusion—laser beam metal (PBF-LB/M), known as well as laser powder bed fusion.

Bioresorbable Scaffolds for Coronary Arteries: Where Do We Stand Today?

open access: yesVIEW Medicine, Volume 1, Issue 1, August 2026.
Bioresorbable coronary scaffolds are moving from thick strut pitfalls to thinner, stronger, healing‐oriented designs. Integrating advances in materials, guided implantation with preparation, size, and postdilation steps, and resorption aligned to healing, we synthesize clinical evidence and chart a roadmap toward intelligent, transient platforms ...

Low Cycle Repetitive Loading of Ti‐6Al‐4V‐Epoxy Composite Lattice Structures for Enhanced Energy Dissipation and Damage Tolerance

open access: yesAdvanced Engineering Materials, Volume 28, Issue 14, 22 July 2026.
Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...
