Summary: This study developed a model for the photo-Fenton process that allows flexible control of H2O2 supply over time, aiming at treatment optimization and determining the optimal profile for H2O2 supply. The model was analyzed through global sensitivity analysis and parameter estimation, resulting in a set of kinetic, stoichiometric, and operative parameters fitted to H2O2, TOC, and O-2 profiles. The model showed excellent fit to experimental data and provides a model-based optimization tool for the H2O2 dosage profile in the photo-Fenton process.

Summary: This study investigated the degradation of Carbamazepine by electro-Fenton oxidation using a FeS2/carbon felt cathode, accelerating the reaction between H2O2 and ferrous ions to produce more hydroxyl radicals and eliminate iron sludge. Various operational parameters were explored, and an empirical kinetic model was established to predict changes in CBZ concentration. The contribution of different oxidation types to the EF process was calculated and the role of the FeS2-modified cathode was verified through kinetic analysis and quenching experiments.

Summary: The study evaluated the oxidative removal of methylene blue from synthetic textile wastewater using a combination of persulfate and heterogeneous Fenton-like process. The optimal conditions for MB removal were determined, and it was found that H2O2 and goethite doses greatly influenced the efficiency of MB removal. Reusing goethite for 5 cycles still maintained a high MB removal efficiency of 93%, indicating its good reusability. Radical trapping experiments identified hydroxyl radicals as the dominant radical for MB removal.

Summary: The cobalt ferrite Fenton catalysts were synthesized using the flow co-precipitation method, and their structure and size were characterized. Annealing the catalysts at different temperatures resulted in increased crystallite size and grain size. The annealed cobalt ferrites showed improved catalytic activity in hydrogen peroxide decomposition and caffeine oxidation reactions, with the optimal annealing temperature being 400 degrees C. Electromagnetic heating significantly accelerated the catalytic reactions. The results suggest that electromagnetically heated cobalt ferrite can be a promising catalyst for water purification.

Summary: The study investigated the sonochemical degradation of acid Violet-7 dye using an ultrasonic bath. Results showed that lower dye concentration, acidic conditions, and lower temperature favored decolorization using only ultrasound, while combining ultrasound with Fenton's reagent resulted in almost 100% decolorization and 80.9% COD reduction.

Summary: In this study, dispersions of a small-molecule drug in biodegradable polylactide were investigated using differential scanning calorimetry and broadband dielectric spectroscopy. The study reveals that the same small-molecule compound can have opposite effects on the mobility of a biopolymer depending on the preparation method, temperature, and polymer enantiomerism. The drug acts as an antiplasticizer for films but as a plasticizer for microfibres. Furthermore, the structural relaxation time of the samples is influenced by the chemical composition and morphology.

Summary: In recent years, there has been a growing demand for materials that enhance tissue regenerative therapies and possess antimicrobial properties. Hydroxyapatite (HAp) emerges as a bioceramic with extended functionalities, but it has disadvantages in terms of mechanical properties and lack of antimicrobial capacity. To overcome these limitations, doping HAp with various cationic ions, including understudied lanthanides, is being explored. This review focuses on the biological benefits of lanthanides and how their incorporation into HAp can modify its morphology and physical properties, presenting potential biomedical applications of lanthanides-substituted HAp nanoparticles (HAp NPs). The importance of studying the tolerable and non-toxic percentages of substitution with these elements is also emphasized.
