  1. (mdry: dry mass of the monolithic sample used for water adsorption, ρb(dry): bulk density of the dry sample, estimated using the particle density and the total specific pore volume (density of the dry monolithic samples used for sorption-ultrasonic measurements is 0.769 g/cm3 as calculated using the dry mass and sample volume), ϕ: porosity, SBET: specific BET surface area, \({V}_{{\rm{pores}}}\): total specific pore volume, \({V}_{{\rm{micropore}}}\): specific micropore volume, \({\phi }_{{\rm{micropores}}}\): micropore porosity, \({\phi }_{{\rm{mesopores}}}\): mesopore porosity, dpart: average particle size (obtained from geometric calculations assuming spherical and identical particle distribution over the sample volume), dmeso: average mesopore size, and dmic: average micropore size).
