Water Vapor Sorption by Soy Proteins, Proteinates and Hydrolysates
Sorption data were obtained using the Proximity Equilibration Cell to equilibrate a sample to the water activity (a(,w)) of a saturated salt slush or by equilibrating a calibrated reference material to the a(,w) of a sample. Soy isolate dispersed in water, heated for 10 and 30 minutes at …

Investigating the glassy to rubbery transition of polydextrose and corn flakes using automatic water vapor sorption instruments, DSC, and texture analysis
… was to investigate the usefulness of automated sorption isotherm methods for determining the glassy to rubbery transition in a model amorphous food material, polydextrose. The automated sorption isotherms were obtained from 20 to 40°C at 5°C intervals using dynamic vapor sorption (DVS). The DVS …

Water repellency effects on liquid- and vapor-phase water exchange in soil and clay minerals
Drought conditions and wildfires can induce soil water repellency. Precipitation shifts are expected to exacerbate drought and wildfire in regions such as the southeastern United States, making it critical to understand how repellency affects water exchange processes in soil. The objectives of this …

Sorption-desorption properties of dual oxide gels in the system BeO-In_O3
Water vapor sorption-desorption isotherms at 2° and 12° have been obtained for a series of eleven heat-treated (2 hour periods) gels selected at every 10 mole per cent in the system Be0-1n203. Two zones of enhanced adsorption occur at compositions of about 40-60 and 90 mole per cent BeO, in a plot …

Caratterizzazione di membrane metalliche e ionomeriche per applicazioni energetiche
… use as a hydrogen separator. The hydrogen sorption in silver palladium alloys was carried out in a gravimetric system on films produced by ELD technique. In the temperature range inspected, up to 400°C, there is still a lack in literature. The experimental data were analyzed with rigorous …

Understanding and Controlling Wettability of Carbon Powders for PEM Fuel Cell Applications
… surfaces. Both contact angle kinetics (CAK) and water vapor sorption (WVS) measurements were then used to examine the relative wettability of several other types of carbon powders, but in the absence of Nafion, and using VC as a benchmark material. It was found that colloid-imprinted carbon (CIC) …

Design, synthesis and analysis of Isoreticular, 2-Periodic, Co(II)/(Mn(II) mixed- and Zn(II) single-ligand metal-organic frameworks for sorption of energy- and environmentally-relevant molecules
… pore size, geometry, flexibility, and adsorption properties. Mixed-ligand MOFs, incorporating two or more distinct ligands, enhance structural complexity and enable tuning of pore features in multiple dimensions, making them highly suitable for gas sorption applications. This study …

Improved Desiccant Coatings for Heat and Water Vapour Transfer on the Matrix Surfaces of Air-To-Air Regenerative Wheels
… and buildings; however, the effectiveness of water vapor exchange in these regenerative wheels appears to be much lower than may be economically feasible. The purpose of this research is to investigate the feasibility of using agglomerated desiccant particle coatings to improve the performance …
