The Interplay of Magnetic Order with the Electronic Scattering and Crystal‐Field Effects in a Metallic Ferromagnet

Advanced Science, Volume 13, Issue 13, 3 March 2026.
The interplay between magnetic ordering and crystal electric field (CEF) excitations plays a pivotal role in defining the low‐energy electrodynamics of quantum materials. By probing the temperature‐dependent THz conductivity in a rare‐earth‐based metallic ferromagnet, we uncover a microscopic connection between localized and itinerant electrons ...

Modulation of in Vitro Digestibility and Bioaccessibility in Aging‐Related Gastrointestinal Models: Effects of Pork Processing Methods

Food Frontiers, Volume 7, Issue 2, March 2026.
Simulated elderly digestion showed markedly lower efficiency than adults. SV processing enhanced peptide release and bioaccessibility, and counteracted the reduced digestive efficiency of the EA model. ABSTRACT This study investigated how gastrointestinal (GI) changes in elderly achlorhydria individuals (EA) affect protein digestibility and peptide ...

Carrier Transport in Electrically‐Driven Photonic Crystal Membrane Lasers

Laser &Photonics Reviews, Volume 20, Issue 5, 6 March 2026.
A model to study carrier transport in photonic crystal lasers with a buried heterostructure active region and a lateral current injection scheme is presented. The model identifies unconventional leakage paths which explain low injection efficiencies and enhanced recombination at the p‐doping interface observed experimentally.

Two‐Dimensional Transition Metal Dichalcogenides Properties Enhanced by Nano‐ and Micro‐Scale Shape Control

MetalMat, Volume 3, Issue 1, March 2026.
This review explores current strategies for shaping two‐dimensional transition metal dichalcogenides (TMDs) beyond their planar form. It highlights how strain engineering, nanopatterning, and growth on complex substrates modulate their mechanical, optical, and electronic properties.
