Revealing the reactivity of individual chemical entities in complex mixtures : the chemistry behind bio-oil upgrading [PDF]

, 2022
Bio-oils are precursors for biofuels but are highly corrosive necessitating further upgrading. Furthermore, bio-oil samples are highly complex and represent a broad range of chemistries. They are complex mixtures not simply because of the large number of

Leveraging Multiple Data Streams for Prioritization of Mixtures for Hazard Characterization

Toxics, 2022
There is a growing need to establish alternative approaches for mixture safety assessment of polycyclic aromatic hydrocarbons (PAHs). Due to limitations with current component-based approaches, and the lack of established methods for using whole mixtures,
