Hydrogen is a promising renewable fuel with broad applications, but its flammability and tendency to leak through metals create safety challenges, necessitating reliable, standalone, and affordable sensing systems. Current hydrogen sensors are often costly, suffer from cross-sensitivity to gases, and are typically not standalone. Our sensing approach is based on the hydrogenation of the fluorophore 1,4-bisphenylethnylbenzene (PEB). This approach encompasses two levels of visual sensing: rapid detection via surface color change and quantitative "litmus paper"-like analysis and cross-section observation, which provides a hydrogen exposure history and other parameters such as hydrogen partial pressure and exposure time. The sensor detection limit is 1 mbar ( © 2025 Hydrogen Energy Publications LLC

In the present study, an adsorbent material (N-dopped Cu/Al@Biochar) was synthesized by integrating N, Cu, and Al atoms into the structure of a biochar. This material was characterized by several physicochemical methods, then applied to the elimination of tetracycline (TC) and norfloxacin (NC). The results obtained showed that the modification method used, although significantly altering the mesoporous structure of the original biochar, generates several functional groups on the surface of the material, giving it excellent adsorption properties. These properties were evaluated by studying the influence of various experimental parameters such as the pH of the solution, the mass of doped biochar, and the contact time on the amount of antibiotic adsorbed. Adsorption studies revealed maximum amounts of TC and NC adsorbed of 65 and 96 mg/g at pH = 8 and 6 respectively with 50 mg of adsorbent for an equilibrium time of 90 min for TC and 60 min for NC at a concentration of 15 mg/L for both antibiotics. This adsorption capacity led to the removal percentages of up to 90 and 82% for TC and NC, respectively. After five cycles of use, a decrease in adsorption efficiency of 9% for TC and 11% for NC was observed, demonstrating the impressive stability of the synthesized material. Kinetic studies revealed that the Elovich and pseudo nth order models are the most appropriate to describe the adsorption kinetics of TC and NC respectively. In addition, the two- and three-parameter isotherm models used in this study revealed multilayer adsorption processes, based on both π-π, n-π, van der Waals bond formation and hydrogen bonds. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2025.

Context: Traceability evaluation is essential for automotive system success, which involves assessing an organisation's ability to track and trace the requirements from the initial conception of the requirement to the delivery of the final product or system. Objectives: This paper presents the development of a graphical user interface which supports the traceability evaluation in PTC Integrity, by displaying the dependency tree, to facilitate consistency and impact analysis in Automotive SPICE standards. Methods: Qualitative and quantitative experimental design and agile development methods were used to identify problems and potential solutions, and user requirements were gathered and analysed thematically. Results: Conceptual ideas for the visualisation and configuration were offered, and keeping the limitations in mind, the dependency tree tool was developed. The scope for future development was also provided. Conclusions: The developed tool is beneficial in automotive development by saving time in impact analysis and improving consistency. © 2023 IEEE.
