Complexation of Eu(III) in Aqueous Solution: Glyphosate vs. N-Methylglyphosate

N-Methylation represents a subtle structural modification of glyphosate that may alter the coupling between ligand protonation and metal coordination, yet its influence on lanthanide complexation remains insufficiently understood. In this study, the protonation and Eu(III) comple...

Abstract Conventional descriptions of adsorption stability emphasize direct adsorbate–surface interactions, leaving the configurational consequences of three-dimensional nanoconfinement insufficiently resolved. Here, simulations reveal how nanoporous topology reorganizes energeti...

A novel reaction kinetics model with metastable end states for shock-induced decomposition of polystyrene

Recent renewed interest in shock-induced decomposition of hydrocarbon polymers has exposed limitations of Arrhenius kinetics in describing in situ particle velocity profiles measured via embedded electromagnetic gauges or photonic Doppler velocimetry. To address this, we develop...

Energy-dependent competing pathways in the plasma processing of fused silica: from topology-selective relaxation to network disordering

Oxygen-plasma processing can attenuate polishing-induced topographic features on fused silica, whereas increasingly energetic bombardment can disorder the near-surface network. Atomic force microscopy, Raman spectroscopy, laser-damage measurements, plasma diagnostics, and molecul...

Overcoming the Dark Current–Spectral Range Trade‐Off in Room‐Temperature Two‐Dimensional Photodetectors via Photothermal‐Assisted Tunneling
