The Degree of Oxidation of Graphene Oxide [PDF]

open access: yesNanomaterials, 2021
We show that the degree of oxidation of graphene oxide (GO) can be obtained by using a combination of state-of-the-art ab initio computational modeling and X-ray photoemission spectroscopy (XPS). We show that the shift of the XPS C1s peak relative to pristine graphene, ΔEC1s, can be described with high accuracy by ΔEC1s=A(cO−cl)2+E0, where c0 is the ...

Oxidation and oxidative stability in emulsions

open access: yesComprehensive Reviews in Food Science and Food Safety, 2023
Abstract Emulsions are implemented in the fabrication of a wide array of foods and therefore are of great importance in food science. However, the application of emulsions in food production is restricted by two main obstacles, that is, physical and oxidative stability.

The Enzymatic Oxidation of Graphene Oxide [PDF]

open access: yesACS Nano, 2011
Two-dimensional graphitic carbon is a new material with many emerging applications, and studying its chemical properties is an important goal. Here, we reported a new phenomenon--the enzymatic oxidation of a single layer of graphitic carbon by horseradish peroxidase (HRP).

Effect of adsorbed polyaniline on the thermal stability of iron and arsenic oxides

open access: yesQuímica Nova, 2000
Iron and arsenic oxide grains are coated with the conducting organic polymer polyaniline. The obtained samples were characterized by infrared spectroscopy, SEM, conducting measurements and thermogravimetry.

Airflow Dynamics and Aluminum Coating Oxidation Behavior under Electric-Arc Spraying with Airflow Pulsations

open access: yesApplied Sciences, 2021
The paper aims to investigate the airflow dynamics of electric-arc spraying (EAS) with airflow pulsation. The study is focused on the dynamic structure of the airflow with an obstacle in the form of crossed electrodes at the steady and the pulsating air ...

Tailored ZnS/Ag/TiOx transparent and conductive electrode for organic solar cells

open access: yesEPJ Photovoltaics, 2019
Organic photovoltaic cells (OPVCs) attract high interest for solar energy harvesting. They are based on organic thin films sandwiched between two electrodes, one of them being transparent and conductive.

The Influence of Graphene Oxide on Nanoparticle Emissions during Drilling of Graphene/Epoxy Carbon-Fiber Reinforced Engineered Nanomaterials

open access: yesAtmosphere, 2020
Graphene oxide (GO) nanoparticles are increasingly being used to tailor industrial composites. However, despite the advantages, GO has shown conceivable health risks and toxicity to humans and the environment if released.

Oxidative stress: oxidants and antioxidants [PDF]

open access: yesExperimental Physiology, 1997
An imbalance between oxidants and antioxidants in favour of the oxidants, potentially leading to damage, is termed ‘oxidative stress’. Oxidants are formed as a normal product of aerobic metabolism but can be produced at elevated rates under pathophysiological conditions. Antioxidant defense involves several strategies, both enzymatic and non‐enzymatic.
