“…These materials have distinctive structural and electronic characteristics. As a result, they are a fascinating class of materials that have piqued the interest of scientists for fundamental research and a variety of applications, including sorption processes [178]. They are highly effective for the treatment of water and wastewater due to their high capacity for adsorbing a wide range of contaminants, fast kinetics, large specific surfaces, and selectivity towards aromatics.…”

Use of dyes as well as colorants in industrial processes has extensively increased. Effluents from various industries such as textile, paint, food, etc. are reported to have a diverse range of colorants. The effluents from these industries are often released into natural water bodies, causing serious water and environmental pollution, to which humans and other species are constantly exposed. Continued changes in climate have also affected water availability for people around the world. Thus, advanced treatments and removal of harmful contaminants from municipal and industrial wastewater are becoming increasingly important. Removal of dyes and colorants from wastewater can be done in a variety of ways, including physical, chemical, and biological treatments. These technologies, however, differ in terms of efficiency, cost, and environmental effect. There are many technological and economic challenges for the wastewater treatment methods currently available. The search for the most suitable strategy for successful degradation or removal of dyes from effluents is an urgent requirement. Previously published research suggests that the use of enzymes for dye removal is a more economic and effective strategy as compared to traditional techniques. Nanoparticles, with their exceptional physicochemical features, have the potential to tackle the problem of wastewater purification in a less energy-intensive way. However, extensive standardization would be a necessity for the use of different nanoparticles. Therefore, intense research in the use of enzymes and nanoparticle-based technologies may provide much needed technological solution for the remediation of a diverse range of dyes from wastewater.

“…The method is based on two processes, initial ultrafiltration (UF) followed by a nanofiltration (NF) treatment [59]. In this case, the future use of innovative nano materials such as carbon nanotubes which have shown great adsorbing and purifying capacity in many other sectors is particularly interesting [60][61][62][63][64][65][66][67]. Incineration represents a theoretically decisive method for solving the problem of OVWs.…”

The present work aims to analyze the various aspects relating to olive-vegetative waters (OVW) with particular reference to environmental problems. As is known, olive-vegetation waters are one of the most polluting by-products of the oil industry. They are produced in large quantities and have a polluting potential. For this reason, an in-depth and detailed analysis of the production chain is reported up to the correct and lawful disposal of the olive-vegetation waters. The chemical characteristics of vegetation waters are described, with particular reference to polyphenols, which are the most important compounds present in vegetation waters. The treatments, enhancement, perspectives and possible uses in agriculture are reported.

“…The use of carbon materials, such as graphene and nanotubes, can facilitate the extraction of metabolites from complex matrices [59][60][61][62], allowing the selective recovery of whole classes of organic compounds based on the electronic interactions between the carbon structure of the extractive solid medium and the molecular structures of metabolites. Extractions with these carbon materials could better work by simply choosing the ideal organic solvent systems [63,64]. In this context, multiwalled carbon nanotubes (MWCNTs) have successfully been proposed [65].…”

Beer is a complex aqueous mixture of organic and inorganic compounds, such as carbohydrates obtained from barley or wheat malts, hops and yeast, ethanol, proteins, vitamins, and minerals. Phenols and their derivatives obtained by chemical interactions with biogenic amines, together superior alcohols and amino acids, are the other compounds present in minor proportions in beer, Phenolic components possess high antioxidant activities, and regulate the oxidative stability of beer, although bitterness of this beverage originates from hops. Since these antioxidants can produce beneficial effects on the human health after consumption, it is challenging to have in hand the molecular profiles of beers, in order to investigate their contents in bioactive compounds. Today, a significant number of small producers have strongly invested in craft beers, produced by using different hop blends, starting materials that are rich in phenolic antioxidants. The present work discloses an instrumental analytical method which enables the rapid obtainment of the molecular profiling of craft beers, with the assistance of selective extractions made by using multi-walled carbon nanotubes (MWCNTs). In this investigation, high-resolution 1H NMR, and LDMS and MS/MS analysis were applied for the “beeromic” analysis of a craft beer brewed in Calabria (the Southern part of Italy). The spectral data, confirmed that this kind of beer predominantly contains the hop bitter metabolites humolones and lupulones, also highlighting the presence of phenols and phenolamides which are known for their bioactivity against cancer. A profile of the principal volatile hop components was also obtained by GC-MS.
