Summary: In this study, porous carbon electrodes were prepared by direct laser sintering on commercial polymer films, which can be used directly without any modification. Combined with a 3D-printed flow reactor, the amount of analyte required during the detection process was significantly reduced. Numerical simulations of analyte velocities under stirring and flowing conditions showed that flow detection is more conducive to improving detection sensitivity. The limit of detection for Pb2+ was found to be about 0.0330 mg/L, and the electrode exhibited good repeatability and stability.

Summary: The use of calcium alginate beads for the extraction and preconcentration of Pb2+ in river water samples is effective in improving method accuracy, detection limit, and enrichment efficiency. The study found that the reuse of CA-beads for six cycles did not significantly affect the extraction and preconcentration efficiency of Pb2+. The Pb2+ concentration in rivers classified as class I and II in Brazil was generally below 2 μg/L when analyzed using the developed methodology.

Summary: Low-temperature sol-gel prepared ZnCo2O4 thin films are used as high-performance HTL for coating perovskite film without anti-solvent. PSCs based on Cu2+ doped ZnCo2O4 HTL and NA-Psk absorber show the highest PCE of 20.0% with no current hysteresis. ZnCo2O4 HTL maintains a higher efficiency compared to PEDOT:PSS HTL due to the resistance to the basic perovskite precursor solution.

Summary: Water pollution caused by heavy metals is a serious threat to the environment and human health. This study developed a novel MnFe2O4 loaded biochar, which was prepared and modified from agricultural waste straw using the sol-gel method, to efficiently remove cadmium (Cd) from water. The results showed that the as-prepared composites had a significantly higher Cd adsorption capacity compared to the original biochar. The spinel loaded biochar exhibited a strong anti-interference ability in binary and quaternary systems, and its magnetic properties facilitated easy separation and recovery from aquatic solutions, with little decrease in adsorption capacity after multiple cycles.

Summary: Metallophytes are plants that can tolerate extreme metal concentrations in soil. A study on the Dugald River gossan in Australia found that there was no direct relationship between the occurrence of metallophytes and prevailing soil metal concentrations. Crotalaria novae-hollandiae was identified as a strong polymetallic indicator-type metallophyte that can accumulate high concentrations of metals in its leaves.

Summary: A CPME protocol followed by GC-MS was proposed for accurate and sensitive monitoring of OCPs in environmental water samples. Monolithic sorbents were compared, and a sol-gel PEG-based sorbent in porous extraction capsules showed the highest extraction efficiency. LODs for OCPs ranged from 0.01 ng mL-1 to 0.03 ng mL-1 under optimized CPME conditions. The developed method demonstrated good trueness with relative recoveries between 90.5% and 105.2% (intra-day) and 93.0% and 105.0% (inter-day).

Summary: In this study, a poly(tetrahydrofuran)-based fabric phase sorptive extraction (FPSE) membrane was used to isolate and determine three antihistamine drugs (carbinoxamine, chlorpheniramine, and diphenhydramine) in human urine followed by HPLC-UV analysis. Among the tested membranes, the sol-gel poly (tetrahydrofuran) sorbent coated FPSE membrane was found to be the most suitable for drug extraction. The engineered affinity of the fabricated membranes allows the extraction of biological samples without previous pretreatment. Experimental parameters were systematically investigated and optimized using a central composite design of experiment and one-factor-at-a-time approaches. The proposed analytical scheme was validated in terms of linearity, selectivity, limit of detection, limit of quantitation, precision, and accuracy, and the membranes were found to be reusable for multiple extractions.

Summary: The high-performance liquid chromatographic (HPLC) and kinetic spectrophotometric methods were established for the determination of valsartan (VAL) in pharmaceutical formulations. The spectrophotometric procedures utilized different strategies to evaluate the VAL content, and the HPLC procedure was optimized using response surface methodology (RSM) and Box-Behnken design (BBD). Both methods showed excellent accuracy and precision, and were validated according to International Conference on Harmonization (ICH) guidelines. The analytical Eco-Scale score demonstrated that these green methods were a better option for VAL quantification.
