The water vapour sorption properties of Sitka spruce determined using a dynamic vapour sorption apparatus

A critical discussion of the physics of wood–water interactions

“…Below this temperature, the difference between equilibrium moisture content reached by adsorption from the dry state and desorption from saturation increases with decreasing temperature (Djolani 1972;Hill et al 2010). This dependence on moisture history is termed sorption hysteresis.…”

“…Experimental results for wood (Djolani 1972;Seifert 1972;Hernández 1993;Hartley and Avramidis 1996;Arevalo and Hernández 2001;Chauhan and Aggarwal 2004) in fact indicate a small difference in swollen volume in a volume versus moisture content plot. Some of these ideas have been applied to sorption hysteresis in wood (Hill et al 2010). Furthermore, it has been suggested that the sorption kinetics displayed at the cell wall level can be linked to hysteresis by considering the process of polymer relaxation in the inter-microfibrillar matrix (Hill et al 2012).…”

A transportable magnetic resonance imaging system for in situ measurements of living trees: The Tree Hugger

“…Wood drying is a major 34 factor in timber processing because of the high cost and the necessity to minimise 35 distortion and fibre collapse. There still remain many fundamental questions 36 concerning water movement in living trees [3] and water loss and uptake in wood [4]. 37 Magnetic resonance imaging (MRI) offers the opportunity to non-destructively and 38 non-invasively study moisture and moisture transport in wood and in particular living 39 wood.…”

NARX Neural Network Modelling of Mushroom Dynamic Vapour Sorption Kinetics

“…In another study, the mass gain due to water vapour adsorption was recorded by placing a balance in the climatic chamber (Stubberud et al, 1995). Instruments using controlled atmosphere microbalances, such as a Dynamic Vapour Sorption apparatus (DVS) have been tested for the automated moisture sorption analysis of pre-dried samples at any desired relative humidity and selected temperature in a comparably short period of time (Argyropoulos et al, 2012;Hill et al, 2010;Kachrimanis et al, 2006;Rocha et al, 2007;Ziegleder et al, 2004). Arlabosse et al (2003) published a comparative study between static and dynamic sorption methods and found that thermodynamic equilibrium was dependent on internal diffusion.…”
