Probing the Energy Landscape of α‐Synuclein Amyloid Fibril Formation by Systematic K‐to‐Q Mutagenesis

Advanced Science, EarlyView.
We use lysine‐to‐glutamine mutations to study the effect of electrostatics on the kinetics and thermodynamics of alpha‐synuclein amyloid fibril formation. We find that mutational effects map on their structural context within fibrils and identify residues that modulate the energy landscape of alpha‐synuclein self‐assembly. Our work outlines a scalable,

Raman Analysis of RNA Nucleotide Strands From SARS‐CoV‐2 Variants and Subvariants: A Step Forward in the Definition of “Raman Genome”

Advanced Science, EarlyView.
Main Raman signals in RNA, related to helical backbone, ribofuranose ring, and nitrogenous bases, are affected by secondary structures that cause hyperchromic effects and significantly alter the Raman intensity. ABSTRACT Raman spectra of RNA nucleotide strands extracted from 20 SARS‐CoV‐2 strains, including the original Japanese isolate, Alpha, Beta ...

Water‐Soluble Luminescent Trityl Radical for Fluorescence/Magnetic Resonance Dual‐Modal Imaging Probe

Advanced Science, EarlyView.
Stable water‐soluble luminescent tris(2,4,6‐trichlorophenyl)methyl (TTM) radicals, TTM‐trisTP3B and TTM‐trisTP9B, were designed and successfully synthesized. They exhibited deep‐red emissions and high photostability in water. TTM‐trisTP3B exhibited dual functionality as a fluorescence imaging (FI) probe and a magnetic resonance imaging (MRI) contrast ...

Self‐Sustaining Sensing Systems: Integration Strategies and Signal–Power Matching in Energy‐Harvesting Electronics

Advanced Science, EarlyView.
Energy‐harvesting‐integrated sensors couple ambient energy conversion with sensing, processing, and wireless communication. This review organizes recent progress through integration architectures and operating principles, revisiting co‐packaged, monolithic, and co‐functional designs together with always‐on, event‐driven, and multi‐modal sensing modes ...

Colossal Magnetic‐Field‐Induced Anomalous Hall Conductivity in a Kagome Antiferromagnet YMn6Sn6

Advanced Science, EarlyView.
Magnetic‐field‐driven spin canting in the kagome antiferromagnet YMn6Sn6${\rm YMn}_6{\rm Sn}_6$ reshapes flat and Dirac bands near the Fermi level, redistributing Berry curvature and producing colossal anomalous Hall conductivity. The study reveals how magnetic configuration and clean‐limit skew scattering cooperate to amplify Hall transport, offering ...

Characterizations of various curvatures on weakly symmetric Kähler manifolds

Filomat
The objective of the present paper is to introduce a special type of semi-symmetric metric connection ∇* on weakly symmetric Kähler manifolds to reduce the manifold, which is Einstein and Ricci flat. Also, we use a non-flat Riemannian manifold called a weakly concircular symmetric manifold and study its geometric properties on a weakly symmetric Kähler

Aspirin‐Derived Salicyl‐CoA Drives Histone Lysine Salicylation Regulated by CBP and SIRT2

Advanced Science, EarlyView.
Aspirin‐derived salicyl‐CoA serves as a previously unrecognized acyl donor for protein lysine salicylation. This study identifies histone lysine salicylation as a reversible epigenetic modification regulated by CBP and SIRT2, expanding the biochemical actions of aspirin beyond its canonical acetylation‐dependent mechanisms and providing a new framework

Solvent‐Free Synthesis of Ultrabright Carbon Dots With Near‐Unity Quantum Yield for High‐Performance Light‐Emitting Diodes

Advanced Science, EarlyView.
A rational, solvent‐free synthesis utilizing 2,6‐diaminonaphthalene produces ultrabright green‐emissive carbon dots. Regulated by a self‐limiting oxidative capping mechanism, excitons undergo ultrafast intra‐particle funneling from the nitrogen‐doped carbon core to emissive surface traps.
