Bay‐functionalized [7]Helicene Bilayer Nanographenes

Advanced Optical Materials, EarlyView.
Bay‐functionalized [7]helical bilayer nanographenes are synthesized via a scalable, modular strategy enabling late‐stage diversification. Tailored methoxy, diketone, and phenazine substitutions precisely tune redox, photophysical, and chiroptical properties, delivering strong electronic circular dichroism and bright circularly polarized luminescence ...

Influence of Platinum Thin Films on the Photophysical and Quantum Properties of Near‐Surface NV Centers

Advanced Optical Materials, EarlyView.
This work investigates the impact of platinum thin films on shallow nitrogen‐vacancy (NV) centers in diamond for quantum sensing applications. Five samples are analyzed with varying nitrogen implantation energies (2.5–60 keV) and changes in optical properties, charge state, and coherence times are reported.

Evaluating Bicarbonate Electrolyzer Configurations for Energy‐Efficient Formate Production

Advanced Sustainable Systems, EarlyView.
Reactive carbon capture (RCC) with bicarbonate electrolyzers (BEs) offers an efficient alternative to gas‐fed CO2 electrolyzers by eliminating regeneration and pressurization steps. This study optimizes BE configurations and compares RCC chains to gas‐fed carbon chains for formate production.

NNMT Orchestrates Metabolic‐Epigenetic Reprogramming to Drive Macrophage‐Myofibroblast Transition in Hypertrophic Scarring

Advanced Science, EarlyView.
In macrophage‐myofibroblast transition, upregulated NNMT depletes S‐Adenosylmethionine‌ (SAM) and nicotinamide adenine dinucleotide(NAD+), thereby triggering epigenetic reprogramming via Histone H3 Lysine 27 acetylation (H3K27ac) accumulation at the promoter region of master transcription factor Prrx1.

Annexin A13 Protects Against Acute Kidney Injury by Inactivating TGF‐β/Smad3 Signaling

Advanced Science, EarlyView.
ANXA13 is negatively regulated by Smad3 and exerts its protective role in AKI by inactivating TGF‐β/Smad3 signaling and Smad3‐p21 cell cycle arrest pathway through binding to TβRI, inhibiting the interaction between TβRI and TβRII, thereby suppressing TβRI phosporylation.
