Immunosuppressive Formulations for Immunological Defense against Traumatic Brain Injury

Advanced Healthcare Materials, EarlyView.
A novel subcutaneous formulation combining alpha‐ketoglutarate, glycolysis inhibitor PFK15, and a myelin peptide reduces inflammation in a mouse TBI model. This formulation promotes regulatory immune cells, enhances autophagy, and improves motor function, suggesting its potential as a prophylactic immunosuppressive therapy to mitigate TBI‐induced ...

Advancements in Understanding the Physicochemical Properties of Reticular Materials: An In Situ and Operando Spectroscopic Perspective

Advanced Materials, EarlyView.
This review explores how in situ and operando spectroscopic techniques reveal the real‐time behavior of reticular materials, including MOFs and COFs. These methods track material formation and functionalization, structural changes, defect formation, dynamic responses to external triggers, and catalytic processes.

Traceless Photopolymerization with Non‐Pulsed Red Light Enables 3D‐Printable Cell‐Laden Hydrogels

Advanced Materials, EarlyView.
The paper presents a red‐light‐induced polymerization process, initiated by the FDA‐approved dye methylene blue and the cytocompatible co‐initiator triethanolamine, for fabricating hydrogels. This photopolymerization process is oxygen‐tolerant, cytocompatible, and, most importantly, leaves no color traces, resulting in completely transparent scaffolds.

Dynamic Magnonic Crystals Based on Spatiotemporal Plasmon Excitation

Advanced Materials, EarlyView.
Hybrid magnonic‐plasmonic metamaterials enabling spatiotemporal optical control of spin‐wave transport are demonstrated. These structures integrate periodic stripes of gold nanodisk arrays with low‐damping yttrium iron garnet films to realize dynamically reconfigurable magnonic crystals.

Ultrafast Light‐Driven Electronic and Structural Changes in LaFeO3 Perovskites Probed by Femtosecond X‐Ray Absorption Spectroscopy

Advanced Materials, EarlyView.
Femtosecond X‐ray absorption spectroscopy (fs‐XAS) at PAL‐XFEL captures ultrafast electronic and structural dynamics in epitaxial LaFeO3 thin films. Combined with DFT and multiplet calculations, the study reveals photoinduced ligand‐to‐metal charge transfer, followed by polaron formation and reduced oxygen 2p‐iron 3d hybridization, explaining key ...
