“…Three intense peaks are observed for PANI at different angles of diffraction (2θ = 15.2, 19.9, and 25.1°) corresponding to the (121), (113), and (322) crystal planes, respectively, as seen in Figure b. The peaks at 19.9 and 25.1° can be ascribed to the periodicities parallel and perpendicular to the PANI polymer chain, respectively . The sharpness (peak width) and intensity (peak height) peaks represent the degree of orientation and density of crystallites in a particular plane, respectively .…”

Herein, a facile and highly effective nonenzymatic electrochemical sensing system is designed for the detection of the antibacterial drug nitrofurantoin (NFT). This electrocatalyst is a combination of a trimetallic Prussian blue analogue and conductive polyaniline coated onto a three-dimensional porous nickel foam substrate. A comprehensive set of physicochemical analyses have verified the successful synthesis. The fabricated electrochemical sensor exhibits an impressively low limit of detection (0.096 nM) and quantification (0.338 nM, S/N = 3.3), coupled with a wide linear range spanning from 0.1 nM to 5 mM and a sensitivity of 13.9 μA nM −1 cm −2 . This excellent performance is attributed to the collaborative effects of conducting properties of polyaniline (PANI) and the remarkable redox behavior of the Prussian blue analogue (PBA). When both are integrated into the nickel foam, they create a significantly enlarged surface area with numerous catalytic active sites, enhancing the sensor's efficiency. The sensor demonstrates a high degree of specificity for NFT, while effectively minimizing responses to potential interferences such as flutamide, ascorbic acid, glucose, dopamine, uric acid, and nitrophenol, even when present in 2−3-fold higher concentrations. Moreover, to validate its practical utility, the sensor underwent real sample analysis using synthetic urine, achieving outstanding recovery rates of 118 and 101%.

This contribution investigates the mathematical description of the release of volatile organic compounds (VOCs) from cellulose-based porous materials, particularly paper, extensively used in food packaging. Prior research has shown that migration kinetics may be significantly influenced by factors such as substance volatility, its chemical structure and polarity, ambient humidity, and interactions with the fibrous matrix of paper. While some deterministic models, based on the second Fick's law, have been used to describe migration, these diffusion models often fall short when applied to fibrous cellulosic materials like paper. The highly adaptive empirical Weibull model has been employed to address these limitations. However, this model also shows its limitations in terms of the physical interpretation of the empirically derived fitting parameters. This contribution proposes to use a mathematical model based on pseudo-first-order kinetics to quantitatively predict the desorption of VOCs from paper into ambient air. The model is based on Langmuir theory and offers a physical interpretability of its parameters, namely, sorption constants. In focusing on VOC transport and emission under isothermal and isobaric conditions, it differs from isothermal adsorption−desorption models. Experimental data for 10 model compounds are used to validate the proposed model and provide insights into the role of polarity, size, chemical structure, and volatility in desorption kinetics. The study demonstrates that the desorption of VOCs from paper can be effectively modeled using pseudo-first-order kinetics, which captures variations across different substances and environmental conditions. These findings provide valuable insights into the kinetics of VOC desorption and its dependence on compound properties, which can inform food packaging design and preservation strategies.
