Vinylbenzyl chloride was grafted onto PVDF and FEP polymer films using radiation-grafting
methodology. Subsequent reaction with trimethylamine and ion-exchange with potassium …

Vinylbenzyl chloride has been radiation grafted onto both PVDF and FEP fluoropolymer
films; subsequent amination and ion-exchange to give the hydroxide ion forms yield anion …

In crude oil production and processing, asphaltene aggregation followed by precipitation is
a major problem for the oil industry as it causes deactivation of catalysts, blocking pipelines …

Upcoming regulations aim to ban per-and polyfluoroalkyl substances (PFAS), including
commercial polymeric PFAS, or fluoropolymers, such as poly (tetrafluoroethylene)(PTFE) …

The basic concepts of solid-state nuclear magnetic resonance (NMR) spectroscopy are
explained in a clear and concise manner. First the reader is introduced to the principles of …

The crystalline structure and molecular mobility of poly (vinylidene fluoride)(PVDF) blended
with poly (methyl methacrylate)(PMMA) have been investigated using solid-state 19 F magic …

Using solid-state 13C NMR spectroscopy of two different asphaltenes, one derived from
petroleum and the other from coal liquids, it was shown that the asphaltene molecular …

Evidence of size-dependent reconstruction in quantum dots leading to changes in bonding
is observed through analysis of the 77Se {1H} cross-polarization magic angle spinning and …

We investigated the crystalline structures of poly (vinylidene fluoride)(PVDF) in PVDF/silica
(SiO2) binary and PVDF/poly (methyl methacrylate)(PMMA)/SiO2 ternary hybrid composite …

Solid-state 1H and 13C nuclear magnetic resonance (NMR) spectroscopic studies on
heptane-extracted Athabasca oil sands asphaltenes show strong support for the “island” or …
