Soil heavy metal contamination and acid deposition: experimental approach on two forest soils in Hunan, Southern China [PDF]
, 2005 In 1985, a tailing dam collapsed in Hunan province (southern China) leading to soil contamination by heavy metals from the tailings waste. Moreover, acid deposition becomes more and more serious in this area. In this context, two forest soils (a red soil

Adsorptive Removal of Heavy Metals by Microalgae [PDF]
Journal of Phycological Research, 2019 In the present study, the optimization of immobilization structures along with Scenedesmus sp. and the determination of heavy metals (Ni, Cr) absorption rate have been investigated. Polymers in combination with salts were performed in alginate in order to study the stability of formed structures in cross linking agents.

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy
Advanced Engineering Materials, EarlyView.Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).
