Summary: Mg/Al layered double hydroxides (LDH) intercalated with Ethylenediamine-tetramethylene phosphonic acid (EDTMP) were synthesized for the removal of Pb2+ and Cd2+ from aqueous solutions. The intercalation of EDTMP increased the adsorption capacity of LDH for both heavy metal ions. The 20EDT-LDH composite achieved a high adsorption capacity of 249.82 mg/g for Pb2+ and 160.85 mg/g for Cd2+, with removal rates of 64.34% and 99.93% respectively.

Summary: This study investigated the adsorption of heavy metals (Cd and Cr) from industrial wastewater using a series of Ca-substituted nickel zinc nanoferrites (CaxNi0.4Zn0.6-xFe2O4 (x = 0.1, 0.2, 0.3, 0.4, 0.5 and 0.6)) (CNZNFs). The effect of calcium doping and contact time on the adsorption of cadmium and chromium ions was examined, and the prepared nanoadsorbents showed high removal efficiencies for both Cd (98.25%) and Cr (51%) ions. Structural analysis confirmed the formation of spinel structured nanoparticles with varying crystallite size and porosity depending on the calcium concentration. The adsorption data was well fitted by the pseudo second order kinetic model and Langmuir isotherm model, with high adsorption efficiencies of Cd (128.20 mg/g) and Cr (23.54 mg/g) observed. The Langmuir isotherm model showed better fitting than the Freundlich isotherm model due to higher correlation coefficients for both heavy metals.

Summary: Identifying sustainable chemical processes relies on selecting enabling materials that directly impact overall performance. Optimal material selection requires matching property targets and incorporating process knowledge. Making multi-scale decisions simultaneously is necessary to determine optimal process configurations, operating conditions, and material structures. Integrating molecular to process scale decisions within an equation-oriented optimization framework leads to large-scale mixed-integer nonlinear programs (MINLP). This article discusses the current state-of-the-art in computer-aided molecular and process design (CAMPD), highlighting key challenges and open questions for future research.

Summary: In order to find the most accurate and efficient techniques for uncertainty modelling (UM) in power system stability analysis, this paper provides a comprehensive review and classification of the available UM techniques. The increasing uncertainties in power systems resulting from renewable energy sources, new loads, and deregulation of electricity markets make probabilistic power system analysis necessary. These factors significantly impact power system stability, requiring computationally intensive simulations including frequency, voltage, transient, and small disturbance stability. A total of 40 UM techniques are collated, providing their characteristics, advantages, disadvantages, and application areas, with a particular focus on accuracy and efficiency. The review recommends the most accurate and efficient UM techniques for probabilistic stability analysis in power systems with a high penetration of renewable energy.

Summary: The synthesis of the organic ligand EBMS and its immobilization onto mesoporous silica led to the successful fabrication of a composite adsorbent (FCA) for the separation, adsorption, and recovery of Tm(III) ions. The FCA displayed high kinetic performance and was unaffected by competing metal ions. The adsorption behavior of Tm(III) ions on FCA followed the Langmuir adsorption isotherm model with a maximum adsorption capacity of 168.57 mg/g. The FCA showed strong selectivity and potential for the effective separation and recovery of Tm(III) ions from waste samples.

Summary: In recent years, research on solar energy-driven photocatalysis materials has gained significant attention due to their potential in addressing the global energy and environmental crisis. However, many semiconductor photocatalysts have a wide band gap, limiting their ability to absorb visible light. Incorporating dopants through plasma-based doping is a highly efficient approach to reduce the band gap and enhance visible light absorption. Plasma-based doping offers advantages such as high reactivity, simplicity, scalability, energy efficiency, homogeneous doping, and flexibility in gas and liquid phase operations. This review discusses recent advancements in plasma-doped semiconductor photocatalysts, their fundamental mechanisms, and their performance in energy and environmental applications.

Summary: This study investigates the influence of the flexible spacer parity of a guest photoactive liquid crystalline dimer on the photonic bandgap features of the cholesteric and twist grain boundary smectic C phases of the host molecule. The results show that the parity of the photoactive dimer affects the width of the photonic bandgap and the blue-shift of the cholesteric phase. Additionally, the parity of the dimer also affects the layer spacing and two-dimensional periodicity of the liquid crystalline phases.

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.

The reaction mechanism involves complex reaction orders for the oxidant and the aromatic aldehyde, while the reaction order for Ru(VI) is one. The proposed mechanism includes two catalytic cycles and the formation and decomposition of complexes. Quantitative structure-activity relationship analysis showed that deactivating groups in the para-position enhance the process.

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 results show that volume fraction and temperature have a significant impact on the thermal conductivity, while sphericity also needs to be considered. A support vector machine regression model was created to analyze the sensitivity of the thermal conductivity to different parameters. The findings indicate that temperature, sphericity, and volume fraction are the most sensitive variables.

Summary: This paper reports on the synthesis, structural characterization, spectral and nonlinear-optical properties of glass nanocomposites made of glass forming ionic liquid crystals and nanoparticles. 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.
