Low-pressure nitrogen sorption serves as an indicator of silica alteration by detecting the nanometer-scale pore structures associated with opal-CT while excluding contributions from larger pores. To apply this method, calibrations with known compositions are not required...

.... The mineral characteristics and the aflatoxin B 1 sorption capacity of Na-bentonite were also determined. By the end of the study, males gained more weight than females in control and Na-bentonite groups (p ≤ 0.0001); the interaction between treatment and sex was not significant (p = 0.6780), however. Some...

We explain it by competitive sorption of methane and water in the coal pore space; methane under pressure replaces part of the adsorbed water from micropores so that this water can easily form hydrate. The difference in the acoustic properties of frozen and hydrate-bearing coal samples is important...
