Thermoassociative Graft Copolymers: NMR Investigation and Comparison with Rheological Behavior
Article Abstract:
The thermoassociative properties of semidilute solutions of graft copolymers containing poly (N-isopropylacrylamide) (PNIPA) side chains are studied by H (sub 1) NMR. Important changes in the environment of the PNIPA chains when the aggregation took place could be studied using the H (sub 1) NMR experiments.

(Super 19) F NMR investigation of mixed surfactants partitioning and kinetic stability of fluorinated nanodroplets in water
Article Abstract:
Oil-in-water fluorinated microemulsion were diluted at high water content, thus taking the system outside the regime of thermodynamic stability. The partitioning of the individual surfactants between aqueous phase and mixed fluoro-nanodroplets as a function of total surfactant concentration was determined.

Influence of hydrogen bonding in the paramagnetic NMR shieldings of nitronylnitroxide derivative molecules
Article Abstract:
Influence of hydrogen bonding in the paramagnetic NMR shieldings of nitronylnitroxide derivative molecules is discussed. A density functional method has been applied for calculating nuclear-shielding tensors in open-shell, paramagnetic, NN molecules.
