Homogeneous stable suspensions obtained by dispersing dry TiO2 nanoparticles in pure ethylene glycol were prepared and studied. Two types of nanocrystalline structure were analyzed, namely anatase and rutile phases, which have been characterized by scanning electron microscopy. The rheological behavior was determined for both nanofluids at nanoparticle mass(More)
We report that the hybrid organic-inorganic compound [(CH3)2NH2][Mg(HCOO)3] shows a marked dielectric transition around Tt∼ 270 K, associated to a structural phase transition from SG R3[combining macron]c (centrosymmetric) to Cc (non-centrosymmetric). This is the highest Tt reported so far for a perovskite-like formate that is thus a promising candidate to(More)
The aim of this chapter is to show how thermooxidative properties of biological fuels can be evaluated by pressure differential scanning calorimetry (PDSC) and used to correctly classify the fuels studied. The onset oxidation temperature (OOT) is an important parameter for estimating the oxidation stability that can be evaluated by the ASTM method.(More)
