Adsorption Isotherms and Kinetics of Acebutolol and Metoprolol on Magnetic Nanocomposite Fe3O4@MIL‐101(Cr)

ChemistrySelect, Volume 8, Issue 48, December 22, 2023., 2023
Below is the graphical abstract which indicates the whole process, from the synthesis of the nanocomposite to the application in the MSPE. The nanocomposite was synthesised through in‐situ chemical co‐precipitation. The nanocomposite was then used in MSPE to enrich the selected β‐blockers in the influent, effluent and river water samples, and the ...

Sulfidation Impacts on the Hydrophobicity of Stepped Iron Surfaces

Advanced Energy and Sustainability Research, Volume 4, Issue 11, November 2023., 2023
Using both static density functional theory and ab initio molecular dynamics, theoretical analysis of the effects of sulfidated nanoscale zero‐valent iron (nZVI) is conducted. The study reveals that the hydrophobicity of the Fe(211) and Fe(210) surfaces can significantly be altered through sulfidation, which in turn impacts the reactive lifespan of ...

Interaction between nanomaterials and the innate immune system across evolution

Biological Reviews, Volume 98, Issue 3, Page 747-774, June 2023., 2023
ABSTRACT Interaction of engineered nanomaterials (ENMs) with the immune system mainly occurs with cells and molecules of innate immunity, which are present in interface tissues of living organisms. Immuno‐nanotoxicological studies aim at understanding if and when such interaction is inconsequential or may cause irreparable damage. Since innate immunity

Enhanced Degradation of Rh 6G by Zero Valent Iron Loaded on Two Typical Clay Minerals With Different Structures Under Microwave Irradiation

Frontiers in Chemistry, 2018
Nanoscale zero valent iron has been a widespread concern in various fields due to its large specific surface area and high reactivity. However, nanoscale zero valent iron (nZVI) is very likely to aggregate and be oxidized, which limit its wide ...
