Summary: This study developed and implemented a one-dimensional heterogeneous dynamic fixed-bed model for CO2 capture at high temperatures. The model successfully predicted the equilibrium and kinetics of CO2 adsorption on a K-promoted hydrotalcite. The model considered two different adsorption sites and incorporated a change in activation energy to explain the observed capacity loss. The model was validated under wet conditions, making it more robust for process optimization and industrial design.

Summary: A theory is proposed to analyze voltammograms and dynamic electrochemical impedance spectroscopy (dEIS) measurements of diffusion-hindered adsorption processes. The theory allows for the calculation of adsorption kinetics and isotherm parameters from a set of voltammograms taken at different scan-rates. The theory also includes the analysis of high frequency impedance spectra measured during potential scans. The presented theory synthesizes previous theories on diffusion-controlled charge transfer and adsorption, and supports the determination of rate coefficients as a function of electrode potential using fast dEIS measurements.

Summary: The interactions between DNA and lysozyme in the surface layer were studied using various experimental methods. Unlike the case with a monolayer of cationic synthetic polyelectrolyte, no continuous network of DNA/lysozyme complexes was formed. The weaker interactions between lysozyme and DNA led to the formation of more disordered aggregates at high lysozyme concentrations in the surface layer.

Summary: The study investigates the simultaneous adsorption of paracetamol and nimesulide using activated carbon, revealing a displacement phenomenon where nimesulide molecules replace active sites previously occupied by paracetamol. The higher affinity between AC and nimesulide is attributed to the more hydrophobic nature of nimesulide. The thermodynamic analysis suggests exothermic, favorable, and spontaneous adsorption with low adsorption energies supporting physisorption.

Summary: The most effective corrosion inhibitors are organic compounds, especially heterocyclic ones, with polar functional groups, nonbonding electrons, and multiple bonds. Dyes efficiently bind to metal surfaces through their electron-rich spots, known as adsorption centers, and have excellent anticorrosive properties. This review work focuses on the interfacial adsorption of dye molecules and how it negatively affects metallic corrosion, using the Langmuir isotherm model to block the active sites.

Summary: The adsorption isotherms, kinetics, and thermodynamics of fluoride ions (F-) on FeOOH powders in water were studied. The results showed that FeOOH/TOCN powder is an excellent and efficient F- adsorbent in water. The adsorption of F- on FeOOH initially formed a monolayer through physical adsorption, and the adsorption kinetics followed the pseudo-second-order model. The thermodynamic analysis indicated that the adsorption process was spontaneous in water.

Summary: This paper proposes a two-lane model with interactions between the lanes and investigates both bidirectional and unidirectional flows. Theoretical expressions for the global density of the system in the steady state are obtained through mean-field analyses, and it is found that the (2 x 2)-cluster mean-field analysis approximates the simulation results well. The phenomena are explained qualitatively through a simple analysis of correlations. These findings provide informative suggestions for actual traffic systems.

Summary: The mathematical modeling of the dynamic adsorption of 8-Hydroxyquinoline on activated carbon in batch and fixed-bed adsorbers is described in this study. The model considers mass transport phenomena and includes axial dispersion, convective transport, intraparticle diffusion mechanisms, and adsorption on the active site. A methodology based on adsorption equilibrium and rate studies is proposed to solve the model, without considering fitting the mass transport parameters for breakthrough curve prediction, which is an important advancement in fixed-bed column design. The equilibrium results show that 8-HQ adsorbs onto activated carbon through dispersive and hydrophobic interactions, with a mass adsorbed of 454 mg g-1. The kinetic study reveals that achieving equilibrium is faster under turbulent stirring regime, and intraparticle transport is governed by surface diffusion. By using information obtained from the batch regime, the packed bed behavior can be interpreted and predicted in a wide range of operational conditions with an error of 10.6% in breakthrough point prediction.

Summary: Recent studies have demonstrated that the rheological properties of systems formed by the self-assembly of long tail sugar-based surfactants into worm-like micelles can be tuned by subtle modifications of the surfactant monomer's molecular characteristics. The anomeric configuration of the surfactant was found to induce significant changes in nanostructure and rheology, with shear-thinning behavior relating to the re-arrangement of worm-like micelles. These findings provide a detailed mechanism by which sugar-based surfactants control the rheology of the fluid, offering potential for future studies in this area.

Summary: This study explores a new approach for targeted cancer treatment by combining chemo- and photothermal therapy using bio-derived polydopamine (PDA) mesoporous nanobowls, which possess exceptional biocompatibility. The results demonstrate that loading the anticancer drug doxorubicin (DOX) into the nanobowls and treating with near-infrared (NIR) illumination significantly enhances pharmaceutical cytotoxicity to cancer cells compared to free DOX. Additionally, combining the DOX loaded nanobowls with photothermal treatment results in nearly 100% cell death. This research highlights the potential of PDA mesoporous nanobowls as a scaffold for combined chemo- and photothermal therapy, offering new opportunities for treating advanced cancer.

Summary: Paper-based diagnostics are becoming more popular in low-cost, point of care analytical techniques, but large scale testing facilities still rely on traditional methods like gel column agglutination. The novel paper-based blood typing method presented here is rapid, scalable, and able to deliver test results in under ten seconds, making it potentially the fastest blood typing test suitable for large scale automation. This method has the potential to significantly reduce the time and cost of blood typing tests, and could lead to the development of a new high throughput and fully automatable system.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
