Obtaining Curvature‐Based HLD Parameters for Single Ionic Surfactants via Small Angle X‐Ray Scattering (SAXS)

open access: yesJournal of Surfactants and Detergents, EarlyView.
ABSTRACT The hydrophilic–lipophilic difference (HLD) for ionic surfactant microemulsions (μEs) can be interpreted as the curvature normalized by the tail length parameter (L), if it is corrected by a factor “bi”, bi·HLD = HLDcurv = HLDbi = bi·ln(S) – kbi·EACN + Ccbi, with bi and kbi representing the curvature sensitivity to changes in salinity (S, g ...

Total X‐Ray Illumination for Absolute Quantification of Crystalline Phases and Amorphous Content in PVDF and P(VDF‐TrFE)

open access: yesMacromolecular Materials and Engineering, EarlyView.
A rigorous method, Total Illumination by X‐rays (TIX), is presented to quantify crystalline and amorphous phases in organic materials. Mitigating challenges such as low microabsorption and high amorphous content, an improved, general framework is established, applicable to polymers, MOFs, biological materials, etc.

Strain‐Induced Density Fluctuations in Glassy Polymers

open access: yesMacromolecular Rapid Communications, EarlyView.
Strain deformation induces the density fluctuations in glassy polymers, resulting in shear‐thinning behavior. ABSTRACT Deformation of glassy polymers induces plastic flow as a result of mechanical instability, ultimately leading to cavitation and fracture of the liquid. Thus, understanding the origin of such mechanical instability is crucial.

Ambiguities in Assigning Single‐Crystal NMR Data to Individual Atoms in the Crystal Structure: A Case Study of Hambergite, Be2$$ {}_2 $$BO3$$ {}_3 $$OH, by 9$$ {}^9 $$Be and 11$$ {}^{11} $$B NMR Spectroscopy, XRD Measurements and DFT Calculations

open access: yesMagnetic Resonance in Chemistry, EarlyView.
The fundamental question of how to assign NMR resonances to specific atoms in the unit cell is addressed by using the 9Be and 11B spectra of the natural mineral hambergite as a model system. ABSTRACT The NMR interaction tensors of 9$$ {}^9 $$Be and 11$$ {}^{11} $$B of hambergite, Be2$$ {}_2 $$BO3$$ {}_3 $$OH, were derived from single‐crystal NMR ...
