INFLUENCE OF THE PRIMARY AND SECONDARY OXIDATION INHIBITORS ON THE OXIDATION STABILITY OF THE MINERAL BASE OILS [PDF]

open access: yesProceedings on Engineering Sciences, 2019
Oxidation stability is one of the most important characteristics of both base oils and finished products. Based on this characteristic, it is possible to evaluate the ability of lubricants to provide a long usage time under different application ...

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

open access: yes, 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 ...

Micropollutant removal by advanced oxidation of microfiltered secondary effluent for water reuse [PDF]

open access: yes, 2014
The removal of micropollutants (MPs) from secondary municipal wastewater by an advanced oxidation process (AOP) based on UV irradiation combined with hydrogen peroxide (UV/H2O2) has been assessed through pilot-scale experiments incorporating ...

Autoxidation and photosensitized oxidation of methyl eicosapentaenoate: Secondary oxidation products. [PDF]

open access: yesAgricultural and Biological Chemistry, 1985
Methyl eicosapentaenoate (methyl 5, 8, 11, 14, 17-eicosapentaenoate) was subjected to autoxidation and methylene blue-sensitized photooxidation. The secondary oxidation products were separated, and characterized by gas chromatography-mass spectrometry.

Salinomycin biosynthesis reversely regulates the β‐oxidation pathway in Streptomyces albus by carrying a 3‐hydroxyacyl‐CoA dehydrogenase gene in its biosynthetic gene cluster

open access: yesMicrobial Biotechnology, 2022
Streptomyces is well known for synthesis of many biologically active secondary metabolites, such as polyketides and non‐ribosomal peptides. Understanding the coupling mechanisms of primary and secondary metabolism can help develop strategies to improve ...

Reoxidation control of refining slag and inclusion modification in TP347H stainless steel

open access: yes工程科学学报, 2016
The secondary oxidation caused by compositions of refining slag and Ca treatment on oxide inclusion was studied in TP347H stainless steel by EF+VOD+IC process. In industrial trials, the aluminum is used as the final deoxidation during VOD process.

Secondary Metabolites for the Reduction of Oxidative Stress

open access: yesMolecules, 2023
Oxidative stress is a condition that occurs when there is an imbalance between the production of reactive oxygen species (ROS) and the body’s ability to neutralize them [...]

Heterogeneous OH oxidation of secondary brown carbon aerosol [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
Light-absorbing organic aerosol, or brown carbon (BrC), has significant but poorly constrained effects on climate; for example, oxidation in the atmosphere may alter its optical properties, leading to absorption enhancement or bleaching.
