Anti‐Carbamylated Protein Antibodies Stabilize Carbamylated Histone H3 to Promote Synovial Activation and Neutrophil Extracellular Trap‐Mediated Bone Loss in Rheumatoid Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Carbamylation, a nonenzymatic post‐translational modification, contributes to rheumatoid arthritis (RA) pathogenesis. Anti‐carbamylated protein antibodies (anti‐CarP) occur in around 50% of patients with RA and associate with greater joint damage. Neutrophil extracellular traps (NETs) are a major source of carbamylated autoantigens. We sought

Carbon Dot Nano‐Spacers in Triazine Networks for Integrated Photothermal Seawater Desalination and H2O2 Production

Carbon Energy, EarlyView.
Cyanated carbon dots (CN‐CDs) are synthesized by the hydrothermal method with carboxymethyl cellulose and cyanobenzoic acid, and CD‐CTN is obtained in situ via cyclotrimerization of CN‐CDs. CD‐CTN possesses excellent photothermal catalytic H2O2 production in seawater, and desalted H2O2 could be obtained, which demonstrates the practical application for

Spatial structure of m- and o-substituted isologous aryl cyanates

, 2020
1. m-Substituted isologous phenyl cyanates exist in solution as mixtures of the syn- and anti-forms. The fraction of the latter, as well as the dihedral angles between the planes of the aromatic ring and CarECN, increase with the increasing acceptor ...

Polarizability anisotropy and spatial structures of aryl cyanates [PDF]

, 1981
1. The polarizability parameters of the cyanate group have been determined. 2. Phenyl cyanate and p-methoxyphenyl cyanate possess a planar, and p-chloro-p-bromo-, and nitrophenyl cyanates possess a nonplanar, conformation in solutions.

Selective Oxidation Strategies for Cost‐Efficient Green Hydrogen Production via Hybrid Water Electrolysis

Carbon Energy, EarlyView.
Hybrid water electrolysis has emerged as a promising alternative to conventional electrolysis for sustainable hydrogen production. The economic potential of replacing water oxidation with organic substrates is assessed. For each substrate, representative electrocatalysts and mechanistic insights are reviewed to identify design principles for optimized ...

Linear and Two‐Dimensional Infrared Spectroscopy of the Multifunctional Vibrational Probe, 3‐(4‐Azidophenyl) Propiolonitrile. Deperturbing a Fermi Triad by Isotopic Substitution

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Linear infrared spectroscopy combined with isotope labeling and density functional theory unravels the origin of a Fermi triad in a multifunctional vibrational chromophore. Ultrafast 2DIR‐spectroscopy reports directly on the dynamics and the intramolecular vibrational energy flow pathways in the isotopically deperturbed system. Abstract Infrared probes
