Summary: Recent developments in the study of self-assembled surfactant structures and multilayers at the solid-solution interface are presented, with a focus on surface structures formed from dilute solutions in the presence of electrolyte and in more concentrated solutions. While sequential adsorption methods using layer-by-layer approaches are well established for polyelectrolytes and their mixtures, the emphasis here is on self-assembly. Opportunities to manipulate wetting properties and generate enhanced wetting characteristics are discussed, along with potential applications in modifying wetting behavior, creating efficient near surface reservoirs for prolonged delivery of active components, and developing smart functionalized surfaces.

Summary: We propose a simple scaling theory to describe the critical effects at rounded meniscus osculation transitions. The theory identifies two regimes, fluctuation-dominated and mean-field-like behavior, separated by an upper critical dimension. The exponent characterizing the scale of the interfacial height is determined by the intermolecular forces in each regime. Numerical studies confirm the theoretical predictions for systems with short-range and longer-range forces.

Summary: This paper proposes a systematic methodology called Integrated Reflected-Transmitted wave-based Imaging (IRTI) for achieving interlaminar delamination imaging of multilayer structures using interface wave. The methodology involves extracting delamination information, designing probe layout, adopting different algorithms for reflected wave-based and transmitted wave-based imaging, and fusing the two imaging results to obtain accurate delamination shape and location. Experimental results on double-layer plates with different delamination shapes validate the effectiveness of IRTI.

Summary: Four methods are applied to calculate the acoustooptic coupling in a one-dimensional phoxonic crystal cavity, investigating linear and quadratic couplings and their dependence on symmetry of acoustic and optical modes. Perturbation theory results are in good agreement with numerical results, and FEM combined with perturbation theory shows advantages over Born approximation. Tuning the defect layer thickness greatly enhances quadratic coupling, opening up possibilities for tunable phoxonic crystals based on nonlinear AO effects.

Summary: The adsorption mechanism of Fe3+, Al3+, and Cu2+ ions on chitosan films was studied using a heterogeneous monolayer model with two types of binding site at varying temperatures and pH levels. The theoretical results suggested a multi-ionic adsorption process with different contributions from amino and hydroxyl groups, resulting in a wide range of adsorption capacities at saturation. The removal mechanism for Al3+ and Cu2+ ions was found to be exothermic, while the adsorption of Fe3+ ions was endothermic.

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 paper fits the adsorption isotherms of carbon dioxide on highly porous activated carbon using advanced statistical physics models to interpret the process. Physicochemical parameters were deduced through the best fitting model, showing CO2 molecules forming a single layer on modified activated carbon and mainly binding in a parallel position with adsorption energies reflecting physisorption. The use of the enthalpy function for thermodynamic evaluation in a CO2 adsorption cooling system revealed a coefficient of performance ranging from 0.09 to 0.19 at regeneration temperatures between 303 K and 343 K.
