“…To overcome this issue, laboratory experiments have produced several promising outcomes, particularly for metal oxide nanomaterials coupled with metal ions/NPs. In the case of CuO and MgO, the use of hazardous materials, significant production expenses, and high energy consumption are their main drawbacks [222,223]. Green synthesis, which is based on using natural sources such as plants and microorganisms to create CuO or MgO nanomaterials, has developed as an option that is environmentally friendly with low costs and energy consumption.…”

Due to the ongoing threat of degradation of artefacts and monuments, the conservation of cultural heritage items has been gaining prominence on the global scale. Thus, finding suitable approaches that can preserve these materials while keeping their natural aspect of is crucial. In particular, preventive conservation is an approach that aims to control deterioration before it happens in order to decrease the need for the intervention. Several techniques have been developed in this context. Notably, the application of coatings made of metal oxide nanomaterials dispersed in polymer matrix can be effectively address stone heritage deterioration issues. In particular, metal oxide nanomaterials (TiO2, ZnO, CuO, and MgO) with self-cleaning and antimicrobial activity have been considered as possible cultural heritage conservative materials. Metal oxide nanomaterials have been used to strengthen heritage items in several studies. This review seeks to update the knowledge of different kinds of metal oxide nanomaterials, especially nanoparticles and nanocomposites, that have been employed in the preservation and consolidation of heritage items over the last 10 years. Notably, the transport of nanomaterials in diverse environments is undoubtedly not well understood. Therefore, controlling their effects on various neighbouring non-target organisms and ecological processes is crucial.

“…However, these approaches are considered inappropriate for pharmaceutical and biological applications owing of their harmful effects on the environment. [14,15] Titanium nanoparticles are highly valuable semiconducting transition metal oxide materials that possess distinctive characteristics including ease of manipulation, affordability, mechanical property, better catalytic, non-toxicity, and exceptional resistance to chemical degradation. Various physical and chemical techniques, including chemical vapor deposition, hydrothermal synthesis, ball milling, solvothermal synthesis, plasma method, sol-gel method, Sono-chemical method, microwave synthesis, and electrophoretic deposition, were employed for the synthesis of TiO 2 NPs.…”

Primary objective of this research was to examine the biogenic production of TiO2 NPs using Brassica juncea (L.) Czern seed and investigate the prospective uses of thus synthesized nanoparticles in the area of biomedicine. The synthesized TiO2 NPs were subjected to characterization using several analytical methods namely TEM, UV‐vis, XRD, FE‐SEM, FTIR and EDAX. The average particle size (TEM) is found to be 38 nm, exhibiting irregular shapes. The FT‐IR spectra indicated that the extract contains functional groups, such as polyphenolic, hydroxyl and carboxylic groups, which are likely responsible for formation of nanoparticles. The cytotoxicity studies of the synthesized TiO2 NPs against breast cancer cells (MCF‐7) and lung cells (A549) are shown to be dosage dependent. The inhibitory doses (IC50) were determined to be 43.98 μg/mL and 74.50 μg/mL on MCF‐7 and A549 cells, respectively. Green synthesized TiO2 NPs were assessed for antioxidant activity inhibition rate (DPPH 89.42 %). TiO2 NPs exhibited a maximal zone of inhibition of Staphylococcus aureus 23±0.20 mm against and 20±0.30 against Klebsiella pneumoniae at a concentration of 100 μg/mL, indicating strong antibacterial activity. The findings suggest Brassica juncea (L.) Czern seed encapsulated TiO2 NPs possesses excellent biological applications which can be explored for its application in pharmaceutical field.

This research investigates the creation, analysis, and assessment of nanostructured catalysts designed specifically for sustainable energy conversion purposes. Nanostructured catalysts were produced by a modified sol-gel technique, employing different ratios of precursor materials and reaction conditions. The morphological analysis showed clear disparities among the catalysts that were manufactured. Catalyst 3 had the most favorable attributes, such as a substantial surface area and pore volume. Catalyst 3 exhibited exceptional electrochemical performance, showcasing remarkable activity and selectivity. It achieved high current density and faradaic efficiency while maintaining low overpotential. The stability tests demonstrated the durability of Catalyst 3, as it showed very little decline in electrochemical performance after several cycles. These results emphasize the need of methodical tuning of synthesis parameters to customize nanostructured catalysts for particular energy conversion applications. In the future, it is important to concentrate on improving the methods used to create something and discovering new combinations of substances that can speed up the process of converting energy in a way that is efficient and does not harm the environment. Nanostructured catalysts have the potential to significantly contribute to the advancement of clean energy technology and the reduction of global environmental consequences by tackling these difficulties.
