A review on the application of differential scanning calorimetry (DSC) to petroleum products

Measurements of the Density and Viscosity of Heavy Oil and Water-in-Oil Emulsions Over a Wide Temperature Range

“…Water is present in almost all steps of crude oil production including exploitation, upgrading, transportation and processing [95] (see also Introduction). Therefore, it is important to evaluate the effect of water on thermodynamic (density) and transport (viscosity) properties oil-water emulsions.…”

Amorphous alloys and differential scanning calorimetry (DSC)

“…It should be mentioned that some authors suggest that the solidus temperature should be used instead of the liquidus temperature [63]. Nonetheless, γ (γ = T x /(T g + T l ) parameter [64], and a reduced glass transition temperature (T rg= T g /T l ) are included in a lot of articles. The solidus temperature is the temperature below which there are only solid phases in equilibrium.…”

Influence of APTES-Decorated Mesoporous Silica on the Dynamics of Ethylene Glycol Molecules─Insights from Variable Temperature 2H Solid-State NMR

“…To explore the impact of confinement effects and to inspect the influence of the APTES modification of the pore surface on the structure and dynamics of ethylene glycol, a combination of differential scanning calorimetry (DSC) and variable-temperature 2 H solid-state NMR ( 2 H ssNMR) is suitable, as recently demonstrated for 1-octanol in porous silica by some of the authors . DSC provides information on physical processes such as melting, crystallization, or glass transitions of ethylene glycol in a confined environment. – Solid-state NMR provides information on the onset of rovibrational motions, which may occur at temperatures different from the macroscopic phase transitions. , Insights into dynamics are accessible by extracting NMR parameters encoded in the line shape of the spectra recorded at different temperatures. For example, the use of quadrupolar nuclei such as deuterium allows for the analysis of intramolecular motions in deuterated molecules via changes in the 2 H ssNMR line shapes. – Thus, the combination of DSC and 2 H ssNMR allows for studying the behavior of the ethylene glycol inside the pores of silica materials and inspecting the impact of the APTES functionalization on the structure and dynamics of the ethylene glycol in confinement.…”
