Field‐Cycling NMR Relaxometry in Tire Elastomer Science

Magnetic Resonance in Chemistry, EarlyView.
Field‐cycling NMR relaxometry has established as an ideal tool to investigate multiscale polymer dynamics. Here, we review and discuss applications on elastomers and elastomer compounds of interest for the tire industry to obtain information on segmental dynamics and on polymer dynamics over different regimes as a function of chain length in polymer ...

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

Magnetic 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

Journal 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 ...

The Age and Origin of Block Deposits in the Victorian Alps, Australia

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Large periglacial block deposits are found in the mountains of southeastern Australia. Despite their widespread distribution, their mode of formation and age are poorly understood. These landforms hold considerable potential to shed light on the nature of cooling during glacial periods. In this paper we present a new study of block deposits in

Laser‐Induced‐Structural Transformation in Ti3CNTx MXene Monitored by Raman Spectroscopy with DFT Insight

Small, EarlyView.
A multi‐wavelength Raman study of microwave‐assisted hydrothermal Ti3CNTx MXene, supported by theoretical calculations, identifies laser‐power thresholds and evaluates its ambient‐condition stability. ABSTRACT MXenes are emerging 2D nanomaterials that have attracted growing attention for their highly tunable atomic structure, composition, and surface ...

Accessing the Magnetic Morphology of Ferromagnetic Molecular-Based Nanoparticles from Polarized Small-Angle Neutron Scattering

Inorganics
Polarized Small-Angle Neutron Scattering is a versatile low-energy neutron scattering technique that allows for the access of magnetic information on nanosize objects of size 2–100 nm, from individual properties like the magnetization distribution inside

A Generalized Automated Framework for Thermal Characterization: From Bulk Materials to Complex Heterostructures

Small, EarlyView.
An automated MATLAB framework for inverse photoacoustic analysis enables precise thermal characterization of complex multilayer films. Application to electrodeposited CuxSe reveals a stoichiometry‐dependent thermal conductivity governed by lattice anharmonicity, not grain‐size scattering, in these superionic materials. ABSTRACT Precise determination of

Fractionation‐Free Protein Corona Quantification Through Synchrotron‐Based Small‐Angle X‐ray Scattering

Small Methods, EarlyView.
A fractionation‐free SAXS approach quantifies protein corona formation on silica nanoparticles under native conditions. By deconvoluting scattering from free and bound proteins, adsorbed mass is directly determined in simple and complex media. The method resolves adsorption regimes and thermodynamics, establishing non‐invasive, in situ characterization
