Space Regolith—such as lunar soil, Martian soil, and other loose materials covering the surfaces of the Moon and Mars—comprises dust, sand, and rock. It is crucial for understanding the geological evolution of the Moon and Mars, human exploration, and even planetary colonization. Low-Field Nuclear Magnetic Resonance (LF-NMR) technology, as a non-destructive, online characterization tool, is ideal for valuable samples. A single test can provide multi-dimensional data on pore structure, moisture content, saturation, and more, enabling a comprehensive assessment of physical properties.

According to incomplete statistics, China's petrochemical industry produces an average of 800,000 tons of oily sludge annually, with the entire sector generating approximately 60 million tons each year. Oily sludge is a type of oil-containing solid waste with significant resource recovery potential. As an advanced technology, Low-Field Nuclear Magnetic Resonance (LF-NMR) can typically complete oil content detection in oily sludge within 2 minutes. It enables rapid evaluation of oil recovery levels and real-time assessment of oily sludge treatment processes.

In most Chinese cities, solid waste is primarily managed through landfilling and incineration, both of which are increasingly associated with environmental concerns. For example, landfills occupy vast amounts of land, while incineration may produce toxic and hazardous gases as well as fly ash. In response, China has begun actively promoting policies focused on waste reduction, classification, and resource utilization, aiming to improve the recycling rate and reduce the overall volume of waste emissions.

An article recently published in February 2020 in the Journal of Tianjin University investigates the distribution patterns of water and diesel within the pores of diesel-contaminated silty soil using nuclear magnetic resonance (NMR) technology.
