Dec 5, 2018 · Microarc oxidation (MAO) is a common surface treatment technology for Mg alloys. The MAO layer, however, often fails to provide long-term protection due to its inherent porosity. Current interests are mostly focused on strengthening the corrosion resistance by combining MAO with other film techniques. In this work, we developed a smart protective system characteristic of superhydrophobicity
Feb 7, 2024 · The development of superhydrophobic materials have demonstrated significant potential in the realm of corrosion protection for aluminum alloy (Al alloy) surfaces. However, the limited mechanical stability of superhydrophobic surfaces has impeded the rapid advancement in this field. In this research, we synthesized an aluminum phosphate (AP) inorganic binder and combined it with hydrophobic
Oct 15, 2023 · During composting, pH is a crucial indicator of microbial activity and population composition [51].The variation in pH values during composting is also shown in Fig. 1.At the start of the composting process (Day 0), the pH of BPA pile mixture was 4.3, known to be due to food waste acidification, which produces organic acids as well as some volatile acids of low-molecular-weight
Mar 15, 2021 · Antibiotic resistance genes (ARGs) have been diffusely detected in several kinds of organic solid waste, such as livestock manure, sludge, antibiotic fermentation residues, and food waste, thus attracting great attention. Aerobic composting, which is an effective, harmless treatment method for organic solid waste to promote recycling, has been identified to also aid in ARG reduction. However
Feb 1, 2024 · From a corrosion engineering perspective, the earliest works regarding ML applications in corrosion science were mostly on developing corrosion-resistant steels for marine applications in the last decade [24, 25]. Though few, ML were also recently implemented for developing corrosion-resistant HEAs.

Apr 15, 2023 · The corrosion resistance of the SN coating was studied utilizing Tafel polarization curves in a 3.5% NaCl solution and was analyzed of the corrosion resistance mechanism. In addition, we also researched the self-cleaning, high-temperature exposure, and acid-alkali resistance tests of SN coatings.
Dec 7, 2023 · Enhanced corrosion and wear resistance of Zn–Ni/Cu–Al 2022/11/21/ · In order to improve the cathodic protection and wear resistance of cold spraying Zn-based coatings, Zn–Ni/Cu–Al2O3 composite coating was prepared by co-depositing Zn powders, nickel-coated Cu powders, and Al2O3 powders on the steel substrate using the low
Jan 30, 2024 · Conserves natural resources: Industrial composting can help to conserve natural resources by reducing the need for landfill space and by diverting organic waste from incinerators. Improves soil quality: Compost is a nutrient-rich soil amendment that can help to improve soil structure, water retention, and fertility.
Apr 8, 2024 · A high yield of environmentally friendly N,S-codoped (N,S-CDs) and N-doping carbon points (N-CDs) carbon dots was achieved through a biochemical oxidation reaction at room temperature in this study. Acetaldehyde, sodium hydroxide, benzotriazole (BTA), and 2-mercaptobenzimidazole (MB) with a similar structure were used as raw materials. The microstructure and properties of the corrosion
Dec 5, 2022 · Modern compost machines are the gateway to a circular economy as it relates to food waste and other compostable material. This decentralized approach to waste management eliminates waste hauling, renders landfills useless, and generates a valuable commodity, compost. Let’s get started. The chemistry of composting: Aerobic Machines Vs.
