Structure and dielectric saturation of water in hydrated polymer electrolyte membranes: inclusion of the internal field energy

Article Abstract:

The nature of the water in hydrated polymer electrolyte membranes (PEMs) is not the same as that of bulk water and affects the rate of diffusion of protons in the material. The traditional methods used in the study of the phenomenon of dielectric saturation assume the presence of a homogeneous or slowly varying external field, conditions that are hard appropriate for (PEMs).

Miscibility determination of a lower critical solution temperature polymer blend by rheology

Article Abstract:

A detailed rheological investigation of a lower critical solution temperature (LCST) blend of deuterated polystyrene-38K/PVME-23K near the critical region is presented. The phase behavior of the blend in the transitional regime was studied by the viscoelastic response of the system during dynamic temperature sweep experiments.

Surface-enhanced Raman scattering of C(sub 60) and C(sub 70) in gold hydrosols

Article Abstract:

C(sub 60) and C(sub70) molecules are studied in detail. A comparison study indicates that these molecules adsorbed on gold nanoparticles by one of their pentagonal faces gives experimental proof of molecule adsorption on metal surfaces.
