Sorption of perfluoroalkylated substances (PFASs) onto granular activated carbon and biochar.
TL;DR: The results indicate that adsorption technology is a feasible method to control the contamination of PFASs, and both GAC and biochar are effective adsorbents forPFASs removal from wastewater.
Journal ArticleDOI
Permittivity and chemical characterization of woody biomass during pyrolysis and gasification
TL;DR: In this paper, a proof of concept for using Electrical Capacitance Tomography (ECT) for monitoring the decomposition stages of woody biomass is done, where the permittivity of the material under test is measured in-vitro using impedance analyzer at different excitation frequencies (20 kHz to 3 kHz).

Dynamic molecular structure of plant biomass-derived black carbon (biochar)
TL;DR: A molecular-level assessment of the physical organization and chemical complexity of biomass-derived chars and, specifically, that of aromatic carbon in char structures suggests the existence of four distinct categories of char consisting of a unique mixture of chemical phases and physical states.
