Strong Proton-Phonon Coupling Drives Fast Ion Transport in Perovskites. [PDF]

Adv Sci (Weinh)
Experimental and computational phonon analysis of ABO3‐type proton conductor BaSnO3 shows that substitution on the B‐site with yttrium forms an imaginary phonon mode which is instrumental for the function as proton conductor. This overcompensates the adverse proton trapping effect of the yttrium.

An Exploratory Study on Graphene‐Based Hybrid Epoxy Coatings for Corrosion Resistance and Self‐Healing

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Corrosion of metallic process equipment in chemical, marine, and offshore industries leads to significant maintenance costs and safety concerns. Conventional epoxy coatings, though widely applied, often deteriorate under harsh conditions due to microcracking, moisture ingress and lack of self‐healing capability.

Comparative Investigation of Three Mg Doping Strategies in NMC811 Cathodes for High‐Energy Density Lithium‐Ion Batteries

Batteries &Supercaps, EarlyView.
Magnesium (Mg) doping is explored as a stabilization strategy for high‐capacity LiNi0.8Mn0.1Co0.1O2 (NMC811) cathodes. Three doping routes are compared, revealing that solid‐state lithiation delivers the best cycling stability. Operando X‐ray diffraction and electrochemical dilatometry link reduced cation mixing and lattice stabilization to improved ...

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

Copper‐Based Conductive Nanoinks: Scalable Synthesis via Continuous‐Flow Microwave‐Assisted Polyol Process

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Microwave‐assisted polyol synthesis in continuous flow produces metallic Cu nanoparticles, using ethylene glycol as solvent and reducing agent, lignin to stabilize the colloid and prevent oxidation, and metal‐seeds for particle size control. Metallic copper nanoparticles are a promising alternative to gold and silver in printed electronics due to their
