Summary: The moisture content of wood cell walls is determined by both environmental conditions and material characteristics of the wood. This study used data exploration to identify the important wood characteristics determining the cell wall moisture content. Chemical composition was found to be the most important predictor of the cell wall moisture content, while in the low moisture range, cellulose crystallinity and hydroxyl accessibility were important predictors, and at high moisture contents, microfibril orientation in the cell walls was important. Overall, no single wood characteristic had a major effect on the cell wall moisture content.

Summary: This study investigated the sorption process of cowpea stored in a chamber with controlled relative humidity. The results showed that cowpea exhibited type III behavior in sorption isotherms and hysteresis effect was observed. Among various models, the Peleg equation provided the best fit for predicting the sorption behavior. The sorption isotherms data were also used to estimate the thermodynamic functions, revealing that the sorption process for cowpea was enthalpy-controlled and nonspontaneous.

Summary: Polysaccharides, even non-ionic ones, can swell in water and generate significant pressure, which can be utilized for actuation purposes or result in structural damage. The investigation of swelling pressure dates back to the 19th century, with thermodynamic considerations developed in the early 20th century. Recent data suggests that the swelling process is mainly driven by enthalpy. The molecular origin of the heat involved in swelling is discussed, taking into account the specific characteristics of polysaccharides or biopolymers with rigid chain conformations that contradict the compact packing necessary for enthalpy stabilization. The elastic energy stored in the rigid structure is proposed to contribute to the heat of swelling and potential work associated with it, which can be explored in the design of actuation or control of swelling.

Summary: This study investigated the wood-water interactions of welded bond-lines of European beech and Scots pine using dynamic vapour sorption equipment. The aim was to understand the water sorption properties of the welded bond-line and how they differ from the unwelded wood. The results showed that the welded wood had lower equilibrium moisture contents and greater hysteresis than the unwelded wood. The diffusion coefficients of adsorption and desorption varied between beech and pine, as well as between welded and unwelded wood.

Summary: A cactus mucilage-gelatin bio-composite film was made using a solution casting method. The effects of citric acid as a crosslinking agent at different concentrations on the film's moisture sorption characteristics and mechanical properties were studied. Results showed that incorporating citric acid reduced the film's moisture content, swelling ratio, water vapor permeability, and moisture sorption tendency. The film with 0.5% citric acid exhibited the best crystallinity and highest tensile strength, making it suitable for food packaging applications.

Summary: The study investigates the adsorption of nicotinamide and propranolol on magnetic-activated carbon, finding that adsorption capacity increases with temperature and propranolol has a higher tendency to form multiple layers. The modeling results suggest that both pharmaceutical compounds adsorb onto the MAC adsorbent via the formation of one or two layers, with propranolol showing a higher tendency for multiple layers. Adsorption energy is estimated to be endothermic, with physical interactions responsible for the adsorption process.

Summary: In this paper, the adsorption phenomenon of carbon dioxide on a synthesized zeolite (ZSM-5) is analyzed using statistical physics treatment and a multilayer model. The results show that CO2 adsorption occurs via a non-parallel orientation on the ZSM-5 surface, and the highest adsorption amount is observed for Zn-ZSM-5. The analysis of the adsorption energies confirms that CO2 adsorption on ZSM-5 zeolite is a physical adsorption phenomenon.

Summary: This study investigates the quaternary adsorption of Cu2+, Co2+, Ni2+, and Ag+ ions on an adsorbent derived from alkaline fusion of wastewater treatment sludge. The study reveals that the adsorption of Cu2+, Co2+, and Ni2+ ions is endothermic, while the adsorption of Ag+ ions is exothermic. In the quaternary system, the adsorption of Ag+ ions is significantly reduced due to the competitive effect of other divalent ions, whereas the adsorption capacities of Cu2+, Co2+, and Ni2+ ions are not significantly affected. There is a notable competitive effect of Cu2+, Co2+, and Ni2+ ions on the adsorption of Ag+ ions. Modelling analysis demonstrates that the adsorption of Cu2+, Co2+, and Ni2+ ions is a multi-ionic process at all tested temperatures, while the adsorption of Ag+ ions is a multi-ionic process only at low temperatures. The statistical physics model confirms that the adsorption energies correspond to physical interactions forces and water molecule adsorption plays a crucial role in removing these trace metals.

Summary: This study aimed to extract oil from catfish heads using CO2 supercritical fluid (SFE-CO2), with varying conditions of extraction time, temperature, and pressure. The yield of crude oil from catfish heads using thermal-mechanical extraction was 86%, with concentrations of EPA and DHA at 9.0% and 11.9% respectively. Supercritical extraction resulted in a yield of 84% at 25 MPa and 40°C in 3 hours, with lower concentrations of EPA and DHA at 2.1% and 9.1% respectively. The highest EPA and DHA concentration of 18.3% was achieved at 25 MPa, 40°C, and 1 hour. The oil obtained through SFE-CO2 showed similar characteristics to oil obtained through thermal-mechanical extraction and chemical refinement, suggesting its potential as a sustainable food production method through green technology.

Summary: This study aimed to develop new delivery carriers based on chitosan-xanthan gum nanoemulsions with tuna oil. The results showed that electrostatic interactions between chitosan and xanthan gum improved the electrostatic stability of the nanoemulsions, while the increased viscosity due to xanthan gum reduced the diffusivity of dissolved oxygen and increased the oxidative stability. Moreover, electrostatic interactions between chitosan and xanthan gum increased the steric and oxidative stabilities of the nanoemulsions.
