Summary: This review critically investigates the effect of using microwave heating technique on the morphology, surface chemistry, and pore structure of Carbon based, minerals and polymeric adsorbents, as well as the adsorption performance of water pollutants using microwave synthesized adsorbents. Competitive comparisons between adsorbents prepared by microwave and conventional heating techniques are discussed, along with suggestions for future development of microwave prepared adsorbents for water pollutants removal. Further development and investigation are still required for using microwave technology in adsorbents preparation.

Summary: Aquatic pollution, including organic debris and heavy metals, poses a serious threat to living organisms. Copper pollution is harmful to humans, and there is a need for effective methods to remove it from the environment. A novel adsorbent, Fr-MMWCNTs-Fe3O4, was developed and characterized in this study. Batch adsorption tests showed that Fr-MMWCNTs-Fe3O4 had a maximum adsorption capacity of 250 mg/g at 308 K and could efficiently remove Cu2+ ions over a pH range of 6 to 8. The results demonstrate the potential of Fr-MMWCNTs-Fe3O4 composites as an efficient adsorbent for removing Cu2+ ions from untreated natural water sources.

Summary: The widespread use of fungicides is causing water pollution. This study focused on carbendazim, a model fungicide, and examined its adsorption on activated carbon (AC). The optimal conditions for carbendazim adsorption were determined to be an AC dosage of 0.3 g, reaction time of 150 min, and pH ranging from 3.0 to 10.0. The adsorption capacity reached 32.31 mg g(-1) under these conditions. The adsorption process was found to be a monolayer adsorption that occurred on the surface of the AC. The study also confirmed that the adsorption of carbendazim was an endothermic process with physical and chemical adsorption. The findings of this study can be applied to other types of AC and provide valuable information for treating fungicide wastewater.

Summary: Activated carbon treated with KMnO4 and impregnated with iron oxide showed the highest adsorption capacity of 108.60 mg/g. The CO2 adsorption isotherm at 25 °C fitted best with the Freundlich model, indicating multilayer adsorption on a heterogeneous surface. The optimum adsorption temperature was found to be 30 °C, and the adsorption followed a pseudo-second-order kinetic with an activation energy of 39.8 kJ/mol. The slight reduction in adsorption capacity after four cycles demonstrated practical efficiency in CO2 capture.

Summary: Given the large amount of harmful pharmaceuticals being released into the water stream, it is crucial to eradicate or reduce these chemicals to a minimum permissible limit. This study reports the fabrication of a magnetic guar gum graphene oxide nano-composite (mGG/GO NC) for the adsorption of ciprofloxacin from wastewater. Various techniques were used to characterize the guar gum and the nanocomposite, and it was found that the adsorption process followed the pseudo second order model and Langmuir isotherm model. The nanocomposite exhibited high adsorption capacity and recyclability, potentially due to a synergistic effect of multiple interactions in the adsorption mechanism.

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.

Summary: This study investigates the effects of different transition metal decorations on B12N12 nanocages on the adsorption properties of nitrosourea drugs using computational methods. The results reveal the presence of weak non-covalent interactions between metals and nanocages, and the interaction between drugs and nanocages plays a significant role in drug adsorption. Compared to free drugs, the adsorption of drugs on nanocages can facilitate electron transfer, reduce energy gaps and chemical hardness, indicating activity at the target site.

Summary: In this study, the selective oxidation of aromatic aldehydes was investigated using Ru(VI) as a catalyst and hexacyanoferrate (III) as a cooxidant in an alkaline medium. 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.

Summary: This study examines the sensitivity of the thermal conductivity of water-based alumina nanofluids to changes in concentration, sphericity, and temperature. 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.
