Improved biological performance of magnesium by micro-arc oxidation [PDF]

Brazilian Journal of Medical and Biological Research, 2014
Magnesium and its alloys have recently been used in the development of lightweight, biodegradable implant materials. However, the corrosion properties of magnesium limit its clinical application.

Real-time quantitative analysis of volatile products generated during solid-state polypropylene thermal oxidation [PDF]

, 2013
Analysis of volatile organic compounds (VOCs) during PP thermal oxidation under three oxygen partial pressures (0%, 21% and 100% of atmospheric pressure) at 140 C was performed by proton transfer reaction coupled with Fourier transform ion cyclotron ...

Microbial acetone oxidation in coastal seawater [PDF]

, 2014
Acetone is an important oxygenated volatile organic compound in the troposphere where it influences the oxidising capacity of the atmosphere. However, the air-sea flux is not well quantified, in part due to a lack of knowledge regarding which processes ...

Effort to improve coupled in situ chemical oxidation with bioremediation: a review of optimization strategies [PDF]

, 2011
Purpose - In order to provide highly effective yet relatively inexpensive strategies for the remediation of recalcitrant organic contaminants, research has focused on in situ treatment technologies. Recent investigation has shown that coupling two common

Incorporating biodegradation and advanced oxidation processes in the treatment of spent metalworking fluids [PDF]

, 2012
The treatment of spent metalworking fluids (MWFs) is difficult due to their complex and variable composition. Small businesses often struggle to meet increasingly stringent legislation and rising costs as they need to treat this wastewater on site ...

Particle size control of biogenic scorodite during the GAC-catalysed As(III) oxidation for efficient arsenic removal in acid wastewaters

Water Resources and Industry, 2020
The synthesis of biogenic scorodite combined with the oxidation of As(III) catalysed by granular activated carbon (GAC) was previously demonstrated. However, the colloidal size of the formed scorodite particles is still a bottleneck, as it would hinder ...

Effect of macromolecular crowding on protein oxidation: Consequences on the rate, extent and oxidation pathways

Redox Biology, 2021
Biological systems are heterogeneous and crowded environments. Such packed milieus are expected to modulate reactions both inside and outside the cell, including protein oxidation.

A novel process of dye wastewater treatment by linking advanced chemical oxidation with biological oxidation

Archives of Environmental Protection, 2015
Dye wastewater is one of typically non-biodegradable industrial effluents. A new process linking Fenton’s oxidation with biological oxidation proposed in this study was investigated to degrade the organic substances from real dye wastewater.

Effect of chemical modification on physicochemical and biological properties of chondroitin sulfate

Polymer Testing, 2022
Chondroitin sulfate (CS) derivatives are useful biomacromolecules for fabrication of biomaterials. However, chemical modifications of CS molecular structure during processing may alter its physicochemical and biological properties. Here, we studied these
