Optical properties analysis is not included in biodiesel quality standards. However, it
provides valuable information about biodiesel and its feedstocks. In particular, very accurate …

Abstract Spent Coffee Ground (SCG) was studied as a potential source of oil feedstock for
biodiesel production as an alternative waste utilisation instead of being disposed as …

Heavy oil and bitumen resources are the most abundant hydrocarbon energy source
worldwide. However, due to their high viscosity, complex thermal enhanced oil recovery …

This paper presents characterization studies of flash point, kinematic viscosity and refractive
index for several biodiesel/diesel blends. Biodiesel is produced from soybean, corn, olive …

The molecular components typically found in today's jet fuels that meet ASTM specification
are almost entirely alkanes and (mostly alkyl) aromatics with cycloalkyl contents seldom …

The refractive index and speed of sound can be applied in many biodiesel studies, such as
the characterization of biodiesels, their feedstocks, diesel/biodiesel blends, and their …

The number of applications of time domain NMR using low-field spectrometers in research
and development has been steadily increasing in recent years with applications ranging …

Conventional methods for determining and monitoring the viscosity of oils are time-
consuming, expensive, and in some instances, technically unfeasible. These limitations can …

The rise in oil prices, global warming, and the depletion of nonrenewable resources have
led researchers to study sustainable alternatives to increasing energy demand. The …

Understanding aging phenomena of alternative fuels, such as fatty acid methyl esters
(FAME), hydrogenated vegetable oil, or synthetic power-to-X products, has become a highly …
