Kinetic modelling of phenols consumption during polyethylene thermal oxidation [PDF]

open access: yes, 2013
Irganox 1010 stabilized PE was monitored by carbonyl build-up and DSC under oxygen. A scheme for PE stabilization by phenols was implemented and its kinetic parameters were calculated from experimental results.

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 ...

Oxidation of cellulose in pressurized carbon dioxide [PDF]

open access: yes, 2009
This work presents first results upon oxidation of type II cellulose by nitrogen dioxide dissolved in carbon dioxide at high pressure. This reaction leads to oxidized cellulose, a natural-based bioresorbable fabric used for biomedical applications.

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.

Partitioning of Organonitrates in the Production of Secondary Organic Aerosols from α‑Pinene Photo-Oxidation

open access: yes, 2022
The chemical pathways for the production of secondary organic aerosols (SOA) are influenced by the concentration of nitrogen oxides (NOx), including the production of organonitrates (ON).

Effect of Ca Additions on Ignition Temperature and Multi-Stage Oxidation Behavior of AZ80

open access: yesMetals, 2018
AZ80, AZX801, and AZX802 alloys were prepared to investigate the ignition temperature and multi-stage oxidation behavior in air. Besides, the microstructures of alloys before and after oxidation were compared.
