Surface reactivity of amphibole asbestos. A comparison between crocidolite and tremolite [PDF]

, 2017
Among asbestos minerals, fibrous riebeckite (crocidolite) and tremolite share the amphibole structure but largely differ in terms of their iron content and oxidation state. In asbestos toxicology, iron-generated free radicals are largely held as one of

Oral Dosed Organo‐Silica Nanoparticles Restore Glucose Homeostasis and β‐Cell Function in Diabetes Rats

Advanced Functional Materials, EarlyView.
An oral nanoplatform, MOP@T@D, which can maintain glucose homeostasis and restore islet β cells in diabetic rats is developed. It achieves efficient intestinal absorption and liver‐targeted delivery. The nanoparticle disintegrates only in response to hyperglycemia to release insulin on demand and provides antioxidant protection through selenoprotein ...

Efficiency of Fenton Oxidation in Reducing High Concentrations of Humic Acid in Aqueous Solutions [PDF]

آب و فاضلاب, 2015
Advanced oxidation processes produce hyperactive hydroxyl radicals that have a high potential for the oxidation of organic compounds. One of these processes is the Fenton process in which iron ion as a catalyst reacts with oxidants in an acid environment

Impact of Surface Functionalization on NV Quantum Properties: Implications for Biosensing with Fluorescent Nanodiamonds

Advanced Functional Materials, EarlyView.
Fluorescent nanodiamonds (fNDs) have emerged as an invaluable quantum sensing platform for biological and biochemical systems. This paper investigates the influence of common surface functionalization strategies for bioconjugation on the quantum properties of nitrogen vacancy (NV) centers in nanodiamonds.

Direct oxidation of organic micropollutants by persulfate and hydrogen peroxide: A potentially misleading contribution in advanced oxidation processes

Chemical Engineering Journal Advances
Advanced oxidation processes (AOPs) are becoming increasingly attractive for the removal of organic micropollutants (OMPs) from water. However, various aspects of AOPs need to be carefully evaluated. Most AOPs involve the introduction of oxidants such as
