Analysis and theory of gas transport in microporous sol-gel derived ceramic membranes [PDF]
, 1995 Sol-gel modification of mesoporous alumina membranes is a very successful technique to improve gas separation performance. Due to the formed microporous top layer, the membranes show activated transport and molecular sieve-like separation factors.

Differential Heat of Adsorption and Isosteres
Langmuir, 2017 Heat of adsorption is a basic thermodynamic property extensively used not only for understanding thermal effects and heat management in industrial gas storage and separation processes but also for development and validation of adsorption models and materials force fields. Despite a long history of theoretical studies and a vast experimental literature,

Sorption isotherms and isosteric heats of sorption of Malaysian paddy [PDF]
Journal of Food Science and Technology, 2012 Understanding the water sorption characteristics of cereal is extremely essential for optimizing the drying process and ensuring storage stability. Water relation of rough rice was studied at 20, 30, 40 and 50 °C over relative humidity (RH.) between 0.113 and 0.976 using the gravimetric technique.

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
