Summary: Non-enzymatic electrochemical sensors are a promising technology for detecting toxic substances and viruses, offering high sensitivity, long-term stability, and excellent reproducibility. Perovskite oxides have emerged as a potential candidate for such sensors due to their low cost, flexible structure, and high catalytic activity. This comprehensive overview covers recent advances in perovskite oxides, including synthesis methods and electrocatalytic mechanisms. The performance of perovskite oxides is enhanced by lattice O vacancies and superoxide oxygen ions, which have excellent properties for electrooxidation. However, their limited electron transfer kinetics, stability, and selectivity necessitate composite materials to improve their readiness for scientific development. The review also identifies future challenges and provides recommendations.

Summary: This study simultaneously quantified four non-steroidal anti-inflammatory drugs (NSAIDs) - paracetamol, diclofenac, naproxen, and aspirin - in mixture solutions using a laboratory-made working electrode based on carbon paste modified with multi-wall carbon nanotubes (MWCNT-CPE) and Differential Pulse Voltammetry (DPV). The performance of the sensor was characterized using cyclic voltammetry, scanning electronic microscopy, and electrochemical impedance spectroscopy. A data compression strategy based on discrete wavelet transform was applied to handle the complexity and high dimensionality of the voltammograms. Partial Least Square Regression (PLS) and Artificial Neural Networks (ANN) were used to predict the drug concentrations in the mixtures. The results showed successful prediction of the concentration of paracetamol and diclofenac using PLS-adjusted models, achieving correlation values of R >= 0.9 (testing set). The ANN model exhibited good prediction results for all four analyzed drugs, with correlation values of R >= 0.968 (testing stage). Overall, the MWCNT-CPE electrode showed potential as a sensor for voltammetric determination and NSAID analysis.

Summary: Because lead is highly toxic, it is important to detect its presence in various samples. However, conventional analytical techniques can be complicated if the lead concentration in the samples is below the detection limit. In this study, the efficiency of lead sorption and preconcentration using polysulfone fibers grafted with acrylic acid was investigated. The optimal conditions for lead extraction were determined, and a correlation curve was established for the determination of lead concentration in water samples.

Summary: In this work, an electrochemical and kinetic study of Pd electrodeposition onto a 7 μm diameter CF ultramicroelectrode was conducted from an aqueous solution containing 1 mM PdCl2 and 1 M NH4Cl as supporting electrolyte at pH = 4.5. The voltammetric study showed that radial diffusion is favored at slow scan rates. The potentiostatic experiment is in agreement with an instantaneous nucleation and growth mathematical model, which considers the formation of separate hemispherical nuclei. The number of nuclei formed on the electrode surface is potential dependent, increasing as the applied potential decreases.
