Low-field NMR-relaxometry as fast and simple technique for in-situ determination of SARA-composition of crude oils

, 2021
In this study a new, fast and simple method based on low field NMR-relaxometry for in-situ determination of SARA (saturates, aromatics, resins and asphaltenes) composition of crude oils was proposed.

Modelling of rheological and chemical properties of asphalt binder considering SARA fraction

Fuel, 2019
Modelling the rheological properties and chemical characteristics of asphalt material has been a hotspot. In this study, 20/40 and 60/80 pen grade asphalt binders named binder A and binder B were used to blend eleven binder samples.

The ability of sarA to limit protease production plays a key role in the pathogenesis of Staphylococcus aureus osteomyelitis irrespective of the functional status of agr

Infection and Immunity
We demonstrate that mutation of the staphylococcal accessory regulator A (sarA) in the USA300 strain LAC limits virulence in a murine osteomyelitis model to a greater extent than mutation of the accessory gene regulator (agr) and that it does so ...

Comparative evaluation on the thermal behaviors and kinetics of combustion of heavy crude oil and its SARA fractions

Fuel, 2019
In situ combustion (ISC) plays a significant role in the exploitation of heavy crude oil. In this study, the thermal behaviors and kinetics of combustion of heavy crude oil and its saturates-aromatics-reins-asphaltenes (SARA) fractions were comparatively

Effects of SARA fractions on low temperature properties of asphalt binders

International Journal on Road Materials and Pavement Design, 2019
Effects of the chemical fraction on the low temperature rheological behaviours of asphalt binders were explored in this study. Four fractions, namely saturate, aromatic, resin and asphaltene (SARA), were obtained from eleven asphalt binders by a novel ...
