Biochar, Vol 4, Iss 1, Pp 1-26 (2022)
Highlights The production, physicochemical properties, and As adsorption mechanisms of pristine and modified biochars were reviewed. Pyrolysis temperature, pH, presence of dissolved organic carbon, surface charge, and microbial activity affect the As

Biochar, Vol 4, Iss 1, Pp 1-17 (2022)
Highlights The surface functionality of pyrolyzed biomass-derived nanoparticles (PBNPs), described here as those derived from bulk biochar and activated carbon, differs from parent material. The literature on PBNPs derived from biochar is growing, un

Expanded phosphorus availability possibly triggered a marine bioproduction boom after 2.3 billion years ago, but its delivery mechanisms remain unclear. Here we propose a kaolinite shuttle which efficiently adsorbs phosphorus in continental weatherin
