Cavity quantum electrodynamics with three-dimensional photonic bandgap crystals

, 2015
This paper gives an overview of recent work on three-dimensional (3D) photonic crystals with a "full and complete" 3D photonic band gap. We review five main aspects: 1) spontaneous emission inhibition, 2) spatial localization of light within a tiny ...

Fasting as Medicine: Mitochondrial and Endothelial Rejuvenation in Vascular Aging

Aging Cell, Volume 25, Issue 2, February 2026.
Aging impairs cerebrovascular health by driving mitochondrial dysfunction, oxidative stress, endothelial failure, and neurovascular uncoupling, leading to BBB breakdown and cognitive decline. In contrast, time‐restricted feeding/eating counteracts these mechanisms by restoring mitochondrial function, activating adaptive nutrient‐sensing pathways ...

Analysis of AISI 316L steel processed by direct energy deposition (L-DED)

Journal of Physics: Conference Series
Abstract The aim of this study was to perform a metallographic analysis of a thick-walled plate made of powdered austenitic steel AISI316L by direct energy deposition (L-DED) process. After the plate was manufactured, it was heat treated and surface machined.

Fine-spot laser direct energy deposition of gradient thin-walled honeycomb structure and compression property analysis

Journal of Materials Research and Technology
Integrating gradient materials with honeycomb structures offers a promising solution for achieving both multi-functional and lightweight. However, conventional laser direct energy deposition (L-DED) with large spot sizes (2–5 mm) limits deposition ...

Productive Energy Fluence (PEF) controller using feed and laser hybrid control for Directed Energy Deposition (DED) [PDF]

Journal of Manufacturing Processes
In metal additive manufacturing (AM), the laser powder-based directed energy deposition (DED) process stands out as a highly promising approach, enabling rapid, layer-wise fabrication and repair of high-volume, complex geometries. DED supports not only custom-tailored designs with single materials but also enables the use of functionally graded ...
