“…State of water in foods can be probed by nondestructive techniques, such as differential scanning calorimetry (DSC) (Furmaniak et al 2015;Farroni and Buera 2014), Fourier transform infrared-attenuated total reflection (FTIR-ATR) spectroscopy (Davis and Elabd 2013) and nuclear magnetic resonance (NMR) spectroscopy (Sun et al 2010). As a surface phenomenon, water adsorption is a result of sorbent-water and water-water interactions.…”

Water content of glutinous rice flour were determined after equilibrium at water activity (a w ) of 0.06-0.98 and temperature of 10, 20 and 30°C. Distribution of water in different states and its evolution with a w were characterized using four composite models. Interactions of water molecules with solid matrix and themselves were further evaluated. The Park model was a more realistic and mechanism-based approach for describing water desorption of glutinous rice flour. Increased equilibrium water induced by lowering temperature existed mostly as strongly bound water with only a few parts as weakly bound water. The water-polymer thermodynamic incompatibility predominated the water mobility, and resulted in a rapid decrease of diffusion coefficient at a w [ *0.7. Water diffusivity behavior with a w suggested water clustering at high a w levels. The Zimm-Lundberg theory, Park model and Brown analysis all revealed that critical a w of water clustering was of 0.81-0.85, depending on temperature, but gave inconsistent prediction about mean cluster size.

Although recent experimental studies have demonstrated that H2 and D2 molecules wet the inner surface of supergrowth carbon nanotubes at low temperatures, characterization of the structural and dynamical properties in this regime is challenging. This Letter presents a theoretical study of self-diffusion in pure and binary H2, D2, and T2 contact monolayer films formed on the inner surface of a carbon nanotube. Our results show that monolayer formation and self-diffusion both in pure hydrogen isotopes and in H2/T2 and H2/D2 isotope mixtures is impacted by nuclear quantum effects, suggesting potential applications of carbon nanotubes for the separation of hydrogen isotopes.
