Polyfluoroalkyl Substances (PFASs) Detection Via Carbon Dots: A Review

PFASs are a class of highly persistent chemicals that are slowly infiltrating soils and waterways. Thus, there is a great need for fast, sensitive, and reliable techniques to detect PFASs. Conventional methods, such as LC-MS/SPE, allow high sensitivities. However, such methods can be complex and expensive. Considering this, it is not surprising that the scientific community has turned their attention to the search for alternatives. New types of PFAS sensors have been reported over the years, ...

Optimizing Exploration: Synergistic approaches to minimize false positives in pegmatite prospecting - A comprehensive guide for remote sensing and mineral exploration

Pegmatites represent a critical source of raw materials for the European Union's future, emphasizing the need to explore new deposits. Remote sensing plays a pivotal role in early-stage pegmatite exploration, generating prospectivity maps to facilitate field validation. The higher the false positive rate, the higher the time and costs required for field campaigns. This study aims to devise an approach that minimizes false positives, optimizing the work of the exploration field team. The propo...
