Summary: The degradation of AB210 dye using a CoFe2O4/NOM magnetic hybrid catalyst (Hb200) in synthetic and industrial effluent samples showed higher efficiency and mineralization with the EF process compared to AO-H2O2. The Hb200 hybrid maintained excellent catalytic activity in multiple cycles, achieving almost complete mineralization of AB210 in industrial effluent with high organic load. Most contaminants, including the toxic bis(2-ethylhexyl) phthalate, were eliminated or transformed after EF treatment with Hb200.

Summary: The hydroxyl radicals ('OH) generated on the anode play a crucial role in the electrochemical oxidation (EO) of organic pollutants for water treatment. Inspired by the oxygen evolution reaction (OER), a strategy of anode selection was proposed to stabilize deeply oxidized states ( *O and *OOH) which contribute to the generation of 'OH. Through the use of MIL-101(Cr)-coated-Ti/TiO2 anodes, fast and complete removal of aniline and phenol, as well as improved energy utilization, were achieved compared to undecorated anodes. Mechanistic investigations and density functional theory (DFT) computations further supported the hypothesis and provided insights for the development of anode materials in the EO process.

Summary: In recent years, sulfite (S(IV)) has been used as an alternative to persulfates to remove antibiotics in wastewater. However, there is a need for a cheap, environmentally friendly, and effective catalyst. This study used a micron-scale iron-carbon composite (mZVI@C-800) coupled with S(IV) to degrade metronidazole (MNZ). The results showed that the MNZ removal rate reached 81.5% under optimized reaction conditions. The introduction of carbon enhanced the corrosion of mZVI, releasing more Fe2+ and improving the efficiency.

Summary: Long-term industrial deposits of DDT pose an environmental threat in Salamanca, Mexico, where native bacteria with potential for DDT biodegradation were isolated and identified. Among the identified species, Bacillus and Pseudomonas were the most abundant genera. Several bacteria showed promising degradation rates of DDT, with Lysinibacillus fusiformis, Bacillus mycoides, and Bacillus cereus being the most effective in converting DDT congeners. Further studies are needed to optimize the conditions for efficient mineralization of DDT.

Summary: In this study, flow injection analysis (FIA) was used as a sample introduction method for an electrospray ionization - ion trap mass spectrometer (ESI-ITMS) to quantify CrPic(3) in commercial supplements. The FIA system operated with ammonium formate as a carrier solution, and cobalt picolinate was used as an internal standard (IS). The results showed that the proposed FIA-ESI-ITMS/MS procedure is a suitable method for the determination of CrPic(3) in such products.

Summary: In this study, a rollover iridacycle complex cis-[Ir(kappa(2)-C-N-L-1)(kappa(2)-N-N-L-1)Cl-2] was synthesized by reacting two equivalents of a new 2-(6-bromopyridin-2-yl)imidazo[1,2-a]pyridine (L-1) type ligand and IrCl3 in dimethylformamide. The rollover complex exhibited an unusual kappa(2)-C-N-cyclometallated ligand fragment involving C-H bond activation and a classic kappa(2)-N-N-donor mode. The structure of the complex was characterized using NMR, IR, and high-resolution mass spectrometry. The complex showed antiproliferative activities against breast cancer lines, and Density Functional Theory (DFT) calculations provided insights into the C-H bond activation process.

Summary: This work describes a serendipitous self-assembly synthesis of non-symmetrical CNN-platinacycle pincer complexes, with an early formation and detection of hydride species. The synthesis involves a formal C-H bond activation and an earlier C-N bond formation, achieved via C-Br bond excision. Experimental results show that the nature of the Pt(II)-starting material does not significantly affect the reaction pathway, and the best yields are achieved using stoichiometric amounts of K2PtCl4, appropriate Schiff base ligand and aniline at 70 degrees C for three days.
