Summary: The widespread use of antibiotics globally has resulted in serious concerns about their environmental and health impacts. Traditional methods of wastewater treatment have been ineffective in completely removing antibiotic residuals. Therefore, this study investigated the adsorption of doripenem, ampicillin, and amoxicillin on a bentonite-chitosan composite. The results showed that all three antibiotics adsorbed onto the composite material in a monolayer formation, and the adsorption capacity increased with temperature. The composite material was found to be a promising adsorbent for removing antibiotics from water and could be used in industrial wastewater treatment.

Summary: This study demonstrates that utilizing the immiscible Mg-Cr system can improve the thermodynamic and kinetic properties of Mg hydrides/deuterides. The formation of nanometer-sized MgD2 domains embedded in a Cr matrix lowers the reaction temperature and reduces the activation energy for hydrogen desorption. This novel strategy of nanostructuring MgH2 by an immiscible matrix shows promise in altering the thermodynamic and kinetic properties for solid-state hydrogen storage 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.

The results show that the addition of FBA reduces the thermal conductivity and lightness of the mortar and offers moderate mechanical properties, energy gain, and CO2 emission reduction. Furthermore, adding ADL to the FBA mortar enhances the compressive strength and plasticity of the composite materials.

Summary: With the increasing importance of buildings' energy consumption, passive solar design strategies such as Trombe walls are receiving more attention for their implementation. A 3D CFD numerical transient analysis was conducted to investigate the dynamic and thermal fields of a passive Trombe wall integrated in a test room. The simulation results showed that an insulated Trombe wall offers improved thermal performance with more pronounced conductive and convective flows, maintaining the temperature within 16-21 degrees C, while the outside temperature of the insulated Trombe wall can reach around 25 degrees C.

Summary: In this paper, simulations using the lattice Boltzmann formulation were conducted to study the two-dimensional advection and anisotropic diffusion. A new LB formulation that introduces a source term into the convection-diffusion equation (CDE) was proposed as an alternative method for heat transfer problems. The new approach preserves the square lattice basis and does not require specific modifications in the relaxation-time expression or equilibrium distribution functions. The model was validated by simulating pure anisotropic diffusion and coupled advection and anisotropic diffusion, achieving excellent agreements with control volume method solutions.
