Summary: A highly selective sensor based on carbon paste electrodes (CPE) and ion-imprinted polymers (IIP) was proposed for the analysis of lead (II) in real water samples. By optimizing the analysis parameters, a linear concentration range and low detection limit were achieved. The method allows accurate quantification of lead (II) in complex samples without pre-treatment.

Summary: In this study, metal-organic frameworks (MOFs) MIL-101(Cr) and nanoparticles were synthesized using the hydrothermal method. The resulting MOF exhibited high porosity and activity centers, leading to excellent electrochemical performance. A fabricated electrochemical sensor based on the MOF displayed good responses for detecting kynurenic acid (KYNA). The sensor showed reversible current responses for KYNA, while the bare electrode had no responses.

Summary: Three regioisomers of L-menthol-substituted magnesium(II) phthalocyanine were obtained and characterized, with one of them having its crystal structure determined. The compounds exhibited maxima in the Q-band, varying quantum yields for fluorescence and singlet oxygen generation, as well as specific oxidation and reduction behaviors in voltammetric studies. DFT methods were used to calculate IR and UV-Vis spectra and optical band gap.

Summary: A novel approach using Pd nanoparticles supported on porous silicon powder was presented, resulting in a Pd/PSi nanocomposite doped carbon-ceramic electrode with synergetic impact on the oxidation of codeine and acetaminophen. The nanostructure showed high electrochemical activity, surface area, fast electron transfer rate, and proper antifouling features, leading to increased peak currents and decreased peak potentials of oxidation. The proposed electrochemical sensor successfully detected ACT and COD in real samples with satisfactory results.
