Nonresonant Surface‐Enhanced Hyper Raman Scattering of Aromatic Amino Acids on Gold Nanoparticles

Journal of Raman Spectroscopy, EarlyView.
The surface‐enhanced hyper Raman spectra of the three aromatic amino acids phenylalanine, tryptophan, and tyrosine, obtained with nonresonant excitation at a wavelength of 1064 nm, are reported. The data are discussed in the context of the interaction of the molecules with two gold nanoparticle plasmonic substrates, as well as intermolecular ...

Dual‐Mediated Aggregate Electrochemiluminescence of Rubrene

Aggregate, Volume 7, Issue 3, March 2026.
Tripropylamine meets triarylamine: The electrochemiluminescence (ECL) behaviors of rubrene (RUB) in aqueous conditions were revolutionized by the inclusion of a triarylamine molecule (TPD) as both redox and supramolecular mediators. ABSTRACT Electrochemiluminescence (ECL) populates the luminescent excited states through electrochemical reactions. It is

Stepwise Optimization of Thermoelectric Performance in Cu3SbSe4‐Based Compounds via Alloying and Hierarchical Structuring

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 2, March 2026.
Under the stepwise optimization strategy, (Sn, Te) co‐alloying functions as the primary initiative to enhance the power factor (PF), while the subsequent incorporation of AgCuTe operates as a synergistic maneuver to suppress lattice thermal conductivity (κlat), thereby concomitantly boosting the dimensionless figure of merit (ZT).

Morphological and Hyperphosphorylation Transitions of Nanoscale Tau Aggregates in Alzheimer's Disease

Advanced Science, Volume 13, Issue 6, 30 January 2026.
Super‐resolution microscopy identifies nano‐sized tau aggregates (nano‐aggregates) and reveals distinct transitions in their morphology and phosphorylation profiles across control, Primary Age‐Related Tauopathy, and Alzheimer's disease brains. Morphology and hyperphosphorylation signatures distinguish physiological from pathological forms, with nano ...
