Low-temperature conversion of Fe-rich sludge to KFeS2 whisker: a new flocculant synthesis from laboratory scale to pilot scale

Sustainable Environment Research, 2021
Herein, a KFeS2 whisker was formed in mass production at a low temperature, with waste cold-rolling sludge as Fe source, which exhibited good performance in the removal of Zn/Ni from real electroplating effluent.

In Situ Constructed Magnetic Core‐Shell Hydrogen‐Bonded Organic Framework‐on‐Metal–Organic Framework Structure: an Efficient Catalyst for Peroxymonosulfate Activation

Advanced Functional Materials, EarlyView.
In this work, a magnetic core‐shell catalyst (HOF‐on‐Fe3O4/ZIF‐67) is successfully synthesized, consisting of a metal–organic framework (ZIF‐67) with magnetic Fe3O4 as the core and a porous hydrogen‐bonded organic framework (HOF) as the shell. The catalyst efficiently activated peroxymonosulfate, resulting in rapid and effective removal of water ...

Sonochemical Functionalization of Glass

Advanced Functional Materials, EarlyView.
A new method for functionalizing glass using ultrasonication of aryl diazonium salts. Aryl radicals generated by ultrasounds react with glass, forming a stable, covalently bonded organic film. The functionalized glass adheres microorganisms such as microalgae, fungi, and bacteria, suggesting potential applications in enzyme production, filtration ...
