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.

Summary: Copper/graphene nanosheets composites (CGCs) were used as multi-gas adsorbents to remove ammonia and sulfur dioxide from the atmospheric environment. The adsorption isotherms of NH3 and SO2 onto CGCs were quantitatively tested at different temperatures and pressures. The results showed that NH3 adsorption is a multi-anchorage process, while SO2 adsorption is a multi-molecule process. The adsorption mechanism was mainly governed by the density of receptor sites and driven by physical interaction forces.

Summary: An advanced monolayer adsorption model was used to study the adsorption of four vanilla odorants on a mouse eugenol olfactory receptor. The results showed that the odorants were adsorbed in a non-parallel orientation and the adsorption process was multimolecular. The adsorption energy values suggested that the odorants were physisorbed and the adsorption mechanism was exothermic. The estimated parameters can be used to quantify the interactions between the odorants and the olfactory receptor.

Summary: The study reveals that the Bi2Ca2Co2Oy phase is the major component in both sintered and laser-textured Bi2Ca2-xNaxCo2Oy materials. Laser texturing significantly improves the microstructural modification and reduces the electrical resistivity, especially with Na-doping. The laser-textured 0.075Na-doped samples exhibit the highest power factor at 650 degrees C, which is 20% and 70% higher than the undoped textured samples and sintered ones, respectively.

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 investigates the adsorption mechanisms of the pesticide compounds Atrazine and diuron and finds that temperature has a significant influence on the adsorption process, with higher temperatures resulting in increased adsorption capacity. Quantum mechanics calculations suggest that the lower adsorption capacity of atrazine may be due to self-repulsion, while the higher adsorption capacity of diuron could be attributed to the effective balance of electrostatic charges between the adsorbent and adsorbate.

Summary: This work focuses on the thermochemistry of solvation of azeotropes. The enthalpies of dissolution of azeotropes in different mediums were determined, and the impact of the structure of the azeotropes on their properties in solution was discussed. A correlation between enthalpies of solvation and molar refraction was used to determine the vaporization enthalpies of azeotropes for the first time. The results were found to be consistent with literature data, obtained using direct and calculated methods. These findings contribute to the analysis of the structure-property relationships of azeotropes.

Summary: In this study, the interactions between doped and pristine coronenes and adenine nucleobases were investigated using Density Functional Theory. The optimal configurations, adsorption energies, charge transfer, and electrical properties of each complex were calculated. It was found that doped coronene had stronger adsorption strength and charge transfer compared to pristine coronene. The stability of the complexes was attributed to non-covalent interactions in the interactive region. The change in electrical conductivity of coronenes after adsorption suggested their sensitivity towards DNA bases. The predicted energy gap and prolonged recovery time for adenine-coronene configurations indicated the potential application of pristine/doped coronene in DNA detection.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.

The study reveals that by exciting the nanocomposites within their absorption band, a control over effective optical nonlinearities can be achieved, allowing the modification of the magnitude and sign of the effective nonlinear absorption coefficient. The proposed strategy using metal-alkanoates based glass-forming ionic liquid crystals and nanoparticles shows great potential for the development of nanophotonics and plasmonics technologies.
