Mass Spectrometry in Authentication and Forensic Approaches for Determining the Origin of Hazardous Chemicals

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Identification of a chemical agent yields insights into its physicochemical properties. By examining the intrinsic characteristics and environment of a compound, information about its history can be gathered. The main objective of authentication/forensic approaches to chemicals is to trace the history of the compound's origin, regardless of ...

An Investigation of Asphaltene Deposition Mechanisms During Natural Depletion Process by a Two Phase Modeling Using Genetic Algorithm Technique [PDF]

Journal of Petroleum Science and Technology, 2017
In this work, the natural depletion process in sandstone and carbonate cores was modeled to investigate the asphaltene deposition mechanisms. A new permeability reduction correlation was proposed based on the Minssieux model that considers a combination ...

Subsurface Hydrocarbon Biodegradation in the Context of Microbial Habitability and Hydrogeologic, Thermal, and Geologic Evolution of the Colorado Plateau

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Subsurface microbial ecosystems associated with hydrocarbon reservoirs are shaped by temperature, salinity, redox gradients, and fluid flow. However, the drivers of microbial activity and hydrocarbon biodegradation over geologic timescales remain poorly constrained.

Euglena sp. and its associated prokaryotic community degrade light crude oil

Journal of Phycology, Volume 62, Issue 5, Page 1417-1422, October 2026.
Abstract Oil enters the environment through natural and anthropogenic sources and poses a serious threat to water and soil. We hypothesized that algae and their associated prokaryotic communities from natural oil seeps are robust systems capable of surviving and degrading anthropogenic oil spills. We isolated Euglena sp.
