source:sciencedirectAbstractRare earth elements (REEs) encompass 15 lanthanides and play a crucial role in modern technology. Despite their essential uses, REEs are emerging environmental contaminants due to their growing presence in industrial, agricultural, and medical applications. For the first time, the species sensitivity distribution (SSD) approach was applied to REEs considering 58 papers including toxicity about Ce, Dy, Er, Gd, La, Lu, Nd, Pr, Sm, and Y. SSD curves were constructed by log-logistic model providing comprehensive comparisons of the sensitivities of different species to t...

source:Yasmin Ahmed SalemMax Planck Institute for Sustainable Materials (MPI-SusMat) researchers have transformed dealloying—traditionally seen as a corrosive, destructive process—into a groundbreaking method for creating lightweight, high-strength alloys. By combining dealloying with alloying in a single step, the team developed nano-porous martensitic alloys using reactive gases like ammonia, which simultaneously remove oxygen and introduce nitrogen into the material's structure.This sustainable approach, published in Science Advances, offers energy-efficient alloy production with potent...
