Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2007 The equilibrium moisture contents of parsley leaves were measured by the gravimetric dynamic method with continuous recording of changes in sample weight. Consequently water activity values were determined. Henderson equation was found to be a good model

Angewandte Chemie, EarlyView.A supramolecular protection–deprotection strategy temporally separates the framework construction from pore‐surface activation in a porous organic salt. In Form I, phenolic OH groups are protected by DMSO, enabling framework formation. Stepwise single‐crystal‐to‐single‐crystal phase transformation (SCSC) affords a dormant intermediate (Form II ...

Angewandte Chemie, EarlyView.Crosslinking of linear polyimines with aromatic diamines via nucleophilic addition converts nonporous polyimine precursors into aminal‐linked porous networks, offering a new strategy for synthesizing porous organic polymers. The resulting materials exhibit high C2 hydrocarbon adsorption capacity, excellent selectivity over CH4, and durable cyclic ...

Study on coal and gas outburst by thermodynamic desorption threshold
Meikuang Anquan, 2023 The desorption process of coal is interpreted from the perspective of thermodynamics. The four pending parameters of temperature-pressure-adsorption equation (TPAE) were obtained by using the measured series isothermal adsorption data of high-order ...

A re-assessment of the isosteric heat for CCl4 adsorption on graphite [PDF]
Applied Surface Science, 2019 We have carried out molecular simulations of carbon tetrachloride adsorption on graphite, in order to investigate the role of the octopole in potential models for the CCl/graphite system, and the temperature dependence of the first-order gas-liquid transition in the first adsorbate layer.
