ITC measurements on sodium fluoride doped with Mg+2
نویسنده
چکیده
2014 Ionic thermocurrent measurements ITC were carried out on NaF doped with 50 ppm Mg+2. The ITC spectrum of a preheated crystal consists of two bands with maximum at 236 and 251 K. The analysis of these bands leads to a migration enthalpy hm of 0.78 and 0.83 eV and to a migration entropy sm of 2.1 and 2.6 K respectively. The value of the ratio sm/hm is comparable to the results of other processes (formation and migration) and is comparable to theoretical expectations. J.

Improved performance of a polymer nanogenerator based on silver nanoparticles doped electrospun P(VDF-HFP) nanofibers.
We report on the electrospinning of poly(vinylidene fluoride-hexafluoropropylene) [P(VDF-HFP)] nanofibers doped with silver nanoparticles for the preparation of a polymer based nanogenerator (PNG). It has been found that the yield of the piezoelectric phase is increased by the addition of silver nanoparticles. Furthermore, defects in the P(VDF-HFP) electrospun fibers are removed resulting in a ...

Recently, a novel antibacterial fluoride dentifrice containing stannous fluoride and sodium hexametaphosphate (Crest ® PRO-HEALTHTM) was introduced. A digital plaque image analysis (DPIA) technique was used to quantify in situ plaque formation in a population carrying out a phased intervention protocol that included: (1) an initial treatment regimen including toothbrushing with standard sodium ...
