17O Quadrupole Coupling Constants in Water

open access: yesMagnetic Resonance in Chemistry, EarlyView.
In water clusters, first‐nearest‐neighbor interactions (1A and 1D) provide the largest contribution and are well captured by an additive donor–acceptor scheme, with improved accuracy upon inclusion of hydrogen bond distance dependence. Second nearest neighbor (D and A*) effects introduce smaller but systematic negative corrections, restoring near ...

Interaction With Surface Spins as a Contribution to Nuclear Magnetic Relaxation of Liquids Adsorbed in Mesoporous Materials

open access: yesMagnetic Resonance in Chemistry, EarlyView.
Liquids at silica interfaces experience demixing as a consequence of their respective polarity. The distribution of liquids and their primary relaxation contributions are studied by surface modification with OD and radical moieties, respectively. ABSTRACT NMR relaxation of liquids in the presence of solid interfaces, such as silica gel or porous glass,

Structure and Dynamics of Ultra‐Low‐Crosslinked Microgels

open access: yesJournal of Polymer Science, EarlyView.
This study reveals the relationship between microgel internal architecture, zero‐shear viscosity, structural relaxation time, and the ability of ultra‐soft colloidal suspensions to remain viscous fluids under overcrowded conditions. This interplay between microgel compressibility and zero‐shear viscosity is further highlighted by a colloid‐polymer ...

Navigating Classical and Nonclassical Realms of Nucleation and Crystallization

open access: yesSmall, EarlyView.
Classical nucleation and growth theories have long been foundational, yet recent nonclassical concepts have challenged and refined our understanding of solid‐state genesis. This paradigm shift introduced new, often ambiguous vocabulary. Here, we clarify key concepts, correct common misconceptions, and provide a terminological field guide across systems,
