In this research, we have demonstrated that two highly hydrophobic phytocannabinoids like delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD), can be loaded on the surface of AuNPs with a one-pot synthesis protocol using trisodium citrate and <span>l</span>-tyrosine as a reducing and stabilizing agents. <span>l</span>-tyrosine plays a crucial role in cannabinoid loading, stability, and shelf life of the AuNPs. After synthesis, the cannabinoid-loaded nanoparticles were characterized with UV–vis spectroscopy, dynamic light scattering (DLS), dark field hyperspectral microscopy, and electron microscopy. The AuNPs function as a scaffold for the attachment and enhanced transport of both cannabinoids inside cancer cells, thus increasing their bioavailability. Hyperspectral microscopy was used to confirm AuNPs uptake. IC₅₀ values in SK-BR-3 human breast cancer cell line for both THC and CBD loaded onto AuNPs were lower by 70.75 % and 37.04 % than those of the aqueous suspension of pure molecules. Compared to the aqueous suspension of pure cannabinoids, this approach induced and enhanced cancer cell death more efficiently. This enhanced efficacy was associated with a decline in cell viability, which is attributed to apoptosis, as indicated by flow cytometry results.

One opportunity for recycling and lessening ecological impact is provided by prepreg carbon cloth waste (PCCW), a byproduct of the CFRP manufacturing process. This study explores the utilization of PCCW<strong>,</strong> which is mechanically processed into shredded prepreg carbon cloth waste (SPCCW) fibres with lengths ranging from 5 to 40 mm and diameters between 0.1 and 1 mm, for concrete reinforcement.

Specific error margins between the simulated and experimental data are mentioned, such as the 1.9 % error in predicting flexural strength, which highlights the accuracy of the finite element model. In this study, the Visco-polymerization cracking model was selected to simulate the cohesive crack propagation in SPCCW-reinforced concrete alongside the concrete plastic damage model to capture the non-linear behaviour of concrete under both tensile and compressive stresses. The experimental results revealed a marked reduction in slump, with the greatest reduction (81.8 %) observed at higher fibre contents. Optimal mechanical performance was achieved at 1.0 % fibre content, where flexural strength increased by 24.9 %. The inclusion of SPCCW fibres facilitated improved stress redistribution and delayed crack initiation and propagation, which was further validated through numerical simulations.

In this context, green hydrogen appears as a beacon of hope, with the potential to reinvent the paradigms of energy consumption, particularly in the transportation and aviation sectors. Hydrogen has long been intriguing owing to its unique characteristics. It is not only an energy transporter; it has the power to alter the game. Its growing significance is due to its capacity to decarbonize energy generation. Traditional hydrogen generation techniques have contributed considerably to world CO&lt;sub&gt;2&lt;/sub&gt; emissions, accounting for over 2 % of total emissions. This environmental problem is successfully addressed by the development of green hydrogen, which is created from renewable energy sources. The International Energy Agency (IEA) predicts a 25 to 30 % increase in global energy consumption by 2040, which is a very grim scenario. If continue to rely on coal and oil, this growing demand will result in greater CO&lt;sub&gt;2&lt;/sub&gt; emissions, exacerbating climate change's consequences. In this situation, green hydrogen is not only an option but a need. Because green hydrogen has properties with conventional fuels, it can be simply integrated into current infrastructure. This harmonic integration ensures that the shift to hydrogen-based solutions in these sectors would not demand a complete redesign of the present systems, assuring cost-effectiveness and practicality. However, like with any energy source, green hydrogen has obstacles. Its combustibility and probable explosiveness have been cited as causes for concern. However, developments in safety measures have successfully mitigated these dangers, ensuring that hydrogen may be used safely and efficiently across various applications. A further difficulty is its energy density, particularly in comparison to conventional fuels. While its energy-to-weight ratio may be good, its bulk poses challenges, particularly in the aviation industry where space is at a premium. Beyond its direct use as a fuel, green hydrogen has potential in auxiliary capacities. It may be used as a dependable backup energy source during power outages, as well as in a variety of different sectors and uses, ranging from manufacturing to residential. Green hydrogen's adaptability demonstrates its potential to infiltrate all sectors of our economy. Storage is an important enabler for broad hydrogen use. Effective hydrogen storage technologies guarantee not only its availability, but also its viability as a source of energy. Current research and advancements in this field are encouraging, which strengthens the argument for green hydrogen. At conclusion, green hydrogen is in the vanguard of sustainable energy solutions, particularly for the transportation and aviation industries. In our collaborative quest of a sustainable future, its unique features and environmental advantages make it a vital asset.
