Summary: A halo-thermophilic bacterial consortium capable of decolorizing azo dye under high salinity and temperature conditions was enriched in this study, with Bacillus identified as the dominant genus playing a key role in the decolorization process. The consortium demonstrated effectiveness in decolorization of metanil yellow G across a wide range of pH values, temperatures, dye concentrations, and salinities. Additionally, various enzymes such as laccase, manganese peroxidase, lignin peroxidase, and azoreductase were found to be involved in the decolorization process, with a proposed pathway for decolorization based on GC-MS and FTIR results.

Summary: The study established the influence of the crystalline phase and agglomeration degree of TiO2 nanoparticles on photocatalytic hydroxyl radical formation and bacterial inactivation in TiO2/SiO2 composite coatings. A relationship between hydroxyl radicals' formation and charge carrier transfer mechanism between defect levels in SiO2 and TiO2 embedded nanoparticles was established through a simple spectroscopic method. This correlation complements the lack of mechanisms behind the photocatalytic activity in TiO2/SiO2 composites.

Summary: A wide range of semiconductor-assisted photocatalytic nanomaterials are being investigated as potential photocatalysts in water treatment. The use of nanocomposites composed of nano-TiO2 and MWCNTs is increasing due to their enhanced photocatalytic efficiency. However, the potential risks of these nanosystems in aquatic systems are not well understood. In this study, the toxic effects of TiO2/MWCNT-CNF nanocomposite on freshwater microalgae were assessed. The nanocomposite showed enhanced dye removal performance but also caused algal growth inhibition and sublethal oxidative stress effects. These findings contribute to a better understanding of the potential hazards of nanocomposites in wastewater treatment.

Summary: Mycoremediation of textile effluents, such as synthetic dyes, is an effective and eco-friendly method. Dyes discharged from industries like textile, food processing, chemical, leather, dyestuff, dyeing, and pharmaceutical can negatively impact the natural ecosystem. Lentinus squarrosulus AF5, a strain of fungus, has been identified as a potential decomposer of these dyes. Proteomic analysis revealed differential protein expression in the strain when exposed to the dyes, indicating the important role of extracellular peroxidases in the decolorization process. UV-Visible, FTIR spectroscopic, HPLC, and LC-QTOF-MS analyses confirmed the degradation of the dyes by Lentinus squarrosulus AF5.

Summary: Experimental and numerical thermal analysis of three partially stabilized zirconia (PSZ) foam-type absorbers with different pore densities was conducted in this study. Results show that increasing pore density leads to a larger temperature difference within the absorber, while increasing airflow rate reduces the temperature gradient between the irradiated face and the rear face. Temperature difference changes are influenced by pore density, airflow rate, and the complexity of internal structure.

Summary: Heterogeneous photocatalysis is an efficient process for degrading recalcitrant and emerging pollutants. In this study, gallium-based catalysts doped with Fe ions (GOFe) showed improved photocatalytic activity for the degradation of Rhodamine B dye. The presence of Fe ions decreased the bandgap of the gallium oxide matrix, allowing it to activate under visible light. The best discoloration results were observed under acidic conditions (pH = 3.00) for both visible and visible-UV light sources.

Summary: Developing highly efficient bifunctional oxygen electrocatalysts is crucial for zinc-air flow batteries. Metal-organic frameworks (MOFs) and covalent organic polymers (COPs) have emerged as promising alternatives due to their designable and controllable atomic-level structures. However, their catalytic performances are limited by conductivity and catalytic activity. In this study, nanosheet FeNi-MOF and iron phthalocyanine rich COP hybrid materials are assembled through the pi-pi stacking effect to create highly efficient bifunctional electrocatalysts. The resulting catalyst exhibits superior catalytic performance and stability, making it a promising candidate for zinc-air flow batteries.

Summary: In this study, we modified the electrolyte cubic plus association equation of state (e-CPA EoS) and integrated it with two electrical conductivity models to estimate the electrical conductivity of 11 monovalent electrolyte solutions in water. The modified e-CPA model demonstrated better performance and the hybridization with electrical conductivity models resulted in two predictive models for estimating the electrical conduction of dilute and concentrated electrolyte solutions. These predictive models showed relative average percentage deviations (AARD) of 11.15% and 13.87% over wide ranges of temperature and electrolyte concentration.
