This study aims to examine the microorganism-fighting properties of the thin layers of TiO2. These TiO2 film as synthesized through a chemical process, in which different concentrations of copper have been added. The ability of films to inhibit the growth of different types of bacteria and fungi was examined using the disk diffusion technique. TiO2 films without additives exhibited mild antibacterial action, with inhibition areas varying according to the dose and type of microorganism. In contrast, the films that received a dose of copper showed significant increases in their ability to inhibit bacterial growth. More prominent detention areas were observed when a dose of 60 µg/mL and a doping concentration of 0.1% were used. According to X-ray diffraction tests, it was revealed that the thin films of TiO2 exhibit a cubic crystalline configuration, indicating their high crystallinity and the variation in the position of the peaks due to the inclusion of copper in their composition. The effectiveness in combating bacteria increased when the size of the crystals was raised from 6.72 nm (undoped) to 8.39 nm in presence of 0.1% copper. Significant changes occurred in the external appearance, as seen in the photographs taken using scanning electron microscopy (SEM). The modifications higher concentration of Cu doping, a transformation from smooth surfaces of pure ZnS to rough and porous layers in the films doped with Cu is observed. Specifically, the study reveals that by adding copper to thin films of zinc sulfide, their effectiveness can be enhanced, paving the way for the advancement of materials with antimicrobial properties.

An investigation has been conducted to determine whether or not novel nanocomposite electrolytes have the potential to improve the efficiency and longevity of fuel cell technology. In this investigation, nanocomposite electrolytes were manufactured by using a methodical methodology. The nanoparticles were included into polymer matrices in order to enhance the ion conductivity and mechanical strength of the electrolytes developed. The composition of nanocomposite electrolytes was improved by altering the amount of nanoparticles and polymers that were present. When compared to traditional electrolytes, the introduction of nanoparticles resulted in considerable improvements in the characteristics of the material. These enhancements included a 15% increase in ion conductivity and a 10% increase in mechanical strength. Fuel cell devices that make use of nanocomposite electrolytes have showed improved performance, with a 10% increase in power density and a 15% gain in efficiency when compared to fuel cell devices that make use of traditional electrolytes. In addition, the environmental impact assessment found that the use of nanocomposite electrolytes resulted in a two percent drop in the amount of energy used, a fifteen percent reduction in the amount of waste generated, and a twenty-five percent reduction in the amount of carbon dioxide emissions. As a result of these discoveries, the potential ofnanocomposite electrolytes to enhance the sustainability and efficiency of fuel cell technology has been brought to light. This opens the door for the creation of next-generation fuel cells that have increased performance and decreased their effect on the environment.

The emergence of connected vehicles has transformed the automotive sector by enhancing the vehicle's functionality, efficiency, and safety. The performance and security of these vehicles significantly rely on the deployment of the over-the-air software update. However, the execution of OTA comes with many challenges, especially with regard to security vulnerabilities and risks. The current paper delves into the complexities of the secure OTA software update for connected vehicles addressing the most critical issues; authentication; encryption and integrity verification, and risk management. Through advanced cryptographic methodologies, stringent authentication processes, and secure communication channels, automotive manufacturers and other service providers can guarantee the integrity and confidentiality of the updates, and consumers' data from malicious attack. Moreover, the paper explores the regulatory and other standards-related matters that control the use of OTA in the automotive sector. An understanding of the secure OTA update mechanisms aids the stakeholders in establishing a resilient connection in connected vehicles boosting consumer trust and the future of the automobiles industry.
