“…The conservation of cultural heritage requires meticulous approaches to preserving artworks, often relying on organic solvents for various restoration and maintenance tasks. Most of the solvents used, while effective, have raised concerns regarding their environmental impact and adverse health effects on conservators [1,2]. Today it has become imperative to commit to sustainable conservation practices, in line with global initiatives such as the EU Green Deal and Agenda 2030.…”

This study investigates the potential of fatty acid methyl esters (FAME) as environmentally sustainable alternatives to traditional solvents for the removal of low-polarity materials commonly found in cultural heritage artefacts. Recognizing the environmental and health concerns associated with conventional solvents, this research focuses on FAME to remove low/non-polarity or non-polar substances used in cultural heritage preservation. Laboratory samples coated with low molecular synthetic resins (LMW) such as Regalrez 1094 and microcrystalline wax were treated with FAME applied in gel to prevent solvent–substrate interactions. Photographic documentation under UV-vis light, optical microscope observations, and spectrocolorimetric analysis were used for assessing surface “cleanness”, while FTIR-ATR spectroscopy was used to detect possible residue from treatment. Moreover, SEM analysis was used for a better understanding of the results. The best results were obtained using FAME base on methyl stearate according to Hansen-RED.

“…Hence, it is important to pay attention to the actual threats posed by the effects of these pollutants on living organisms [17,18], as well as the uncontrolled spread of petroleumderived substances in the natural environment [19,20]. Petrochemical products lead to the destabilization of soil health [19,21], contributing to the formation of anaerobic conditions in the soil, leading to the phenomenon known as soil necrosis.…”

The research focused on assessing the response of oxidoreductases (dehydrogenases and catalase) and hydrolases (urease, acid phosphatase, alkaline phosphatase, arylsulfatase, and β-glucosidase) to diesel oil (DO) and gasoline (G) contamination of soils subjected to phytoremediation with Zea mays. The activity of enzymes constitutes one of the fundamental mechanisms for the removal of contaminants from soil, which have the potential to contaminate not only the soil but also groundwater and water reservoirs. Additionally, correlations between enzyme activity and the basic physicochemical properties of the soil were determined. The interaction of perlite and dolomite with soil enzymes and the cultivated plant was also tested. The study was carried out in a pot experiment, where soil contaminated with DO or G was artificially treated at doses of 0, 8 cm3, and 16 cm3 kg−1. Perlite and dolomite were applied for remediation at doses of 0 and 10 g kg−1 of soil. Zea mays was found to respond to the tested pollutant with a reduction in biomass. DO affected the growth of this plant more than G. DO reduced the yield of aerial parts by 86% and G by 74%. The negative effects of these pollutants on the growth and development of Zea mays were mitigated by both perlite and dolomite. DO exerted greater pressure than G on the activity of oxidoreductases and hydrolases, as well as on the physicochemical properties of the soil. DO enhanced the activity of oxidoreductases and most hydrolases, whereas G inhibited them. The implementation of dolomite intensified the activity of all enzymes, except AcP (acid phosphatase) and Glu (ß-glucosidase), in soil contaminated with DO and G, and also improved its physicochemical properties. Perlite induced less significant effects than dolomite on soil enzymes and the physicochemical properties of the soil.

High‐Performance Ceramic Catalyst Filters with Textured Waveguides for Efficient Removal of Volatile Organic Compounds

The cordierite‐based ceramic catalyst filter (CCF) has attracted considerable attention as a promising future air purification system due to its ability to filtrate particulate matter (PM), as well as decompose volatile organic compounds (VOCs) through ultraviolet (UV)‐activated photocatalytic reactions. Its performance, however, is strictly limited because majority of UV photons are absorbed near the entrance of the high‐aspect‐ratio air‐flow channels, thus, only a limited portion of photocatalysts is activated during the flow of polluted air. In this study, a high‐performance CCF is presented featuring textured waveguides (TWs) aligned with an array of UV light‐emitting diodes (LEDs) emitting at a peak wavelength of 365 nm, which are inserted into an array of high‐aspect‐ratio channels. TWs ensure the delivery of UV photons deep inside channels via total internal reflection and scattering, enabling the activation of majority of photocatalysts, resulting in remarkable improvement in VOCs removal efficiency. The proposed CCF system exhibits much higher formaldehyde (HCHO) removal efficiency by 70% compared to conventional CCF systems even subjected to much lower UV light power densities. It is strongly believed that it is possible to further improve the removal efficiency, while maintaining effective PM filtering and ultralow electrical power consumption, by optimization of the geometry of the CCF system with TWs.
