Summary: This study developed a novel Fe-based metallic glass (MG) catalyst with excellent degradation rate and reusability by tailoring the contents of Co and Ni and structural design. The process of dye degradation by a Fenton-like oxidative reaction with H2O2 can have low activation energy, assisted by a reductive reaction with nickel hydride formation.

Summary: A 1D/2D g-C3N5/g-C3N4 heterojunction was prepared for the removal of methyl orange (MO) from wastewater through direct thermal polymerization. The characterization analysis showed that 1D/2D-N5/N4 consisted of one-dimensional g-C3N5 nanorods and two-dimensional g-C3N4 nanosheets. The formed heterojunction between g-C3N5 and g-C3N4 improved the absorption intensity and inhibited the recombination of photoelectrons and holes, leading to a photocatalytic removal rate of 99.6% for MO. Moreover, the similar π-π* conjugated systems between g-C3N5 and g-C3N4 also enhanced the photocatalytic activity of 1D/2D-N5/N4. The present work demonstrated that 1D/2D-N5/N4 is an efficient photocatalyst for MO removal.

Summary: A detailed mechanism for the combustion of methyl isocyanate is proposed for the first time. The mechanism contains 130 reactions and was merged with the reaction base proposed by Glarborg et al. Experimental data related to the pyrolysis of methyl isocyanate were simulated in a closed reactor and a good agreement was observed. Additionally, the auto-ignition temperature (Ti gn) of methyl isocyanate was calculated based on the standard ASTME659-78 test and was close to the experimental value. Flow rate and sensitivity analysis were performed to highlight the main reaction pathways.

Summary: In this study, a graphene oxide-based lanthanum hydroxide/chitosan foam (CSGOL foam) was synthesized for arsenate (As(V)) remediation in surface water. The foam exhibited high adsorption capacity and stability, effectively removing As(V) from water. Continuous column experiments demonstrated its ability to bring the As(V) concentration in real surface water below the WHO drinking water standards. XPS analysis and batch studies indicated that the removal mechanism involved electrostatic and surface complexation through chemical interaction.

Summary: Biphasic calcium phosphate microspheres were synthesized using the water on oil emulsion method, and withaferin A was incorporated to evaluate their efficacy. The formation of biphasic calcium phosphates was confirmed by X-ray diffraction. Although BCP-WFA-ALG microspheres showed the highest current density, their contact angle was lower than the control BCP microspheres in all media. Water uptake into BCP-WFA-ALG microspheres was significantly higher, and MTT assay showed enhanced cell proliferation. Osteogenic differentiation of MG 63 cells on BCP-WFA-ALG microspheres exhibited increased expression of osteogenic marker genes.

Summary: In this study, non-thermal plasma discharge was used to potentially remove As(III) in contaminated water, achieving enhanced redox adsorption. Reactive species generated by plasma-water interaction were utilized to transform As(III) to As(V) and modify the surface of the adsorbent, MnOFe2O3. The catalytic adsorption ability of the adsorbent was improved by 30% via the redox adsorptive mechanism. Batch kinetics and isotherm studies demonstrated the effectiveness of the adsorption process, and the adsorption yield was estimated through surface analysis techniques.

Summary: Water is a major source of human diseases due to contamination with bacteria and other pathogenic microorganisms. This review focuses on microbial hazards in water and wastewater, and the use of sonochemical reactors (SCRs) combined with advanced oxidation processes (AOPs) for disinfection. Various types of cavitation reactors, including acoustic cavitation reactors (ACRs) and hydrodynamic cavitation reactors (HCRs), have been employed for the treatment of contaminated waters. Bacterial degradation is primarily caused by thinning of microbial membranes, local warming, and free radical generation due to cavitation. The mechanisms and effects of cavitation in the disinfection process are still poorly understood.
