Bio‐oil upgrading via ketonization of carboxylic acids on Na promoted Ca/AlOx catalysts

open access: yesCarbon Neutralization, 2022
Ketonization of carboxylic acids is valuable for bio‐oil upgrading and producing bio‐derived chemicals. Ca/AlOx metal oxides with various Ca/Al ratios have been prepared by the low‐cost and natural abundant metals in the process. The addition of alkaline

Predicting Subclinical Ketosis in Dairy Cows Using Machine Learning Techniques

open access: yesAnimals, 2021
The diagnosis of subclinical ketosis in dairy cows based on blood ketone bodies is a challenging and costly procedure. Scientists are searching for tools based on results of milk performance assessment that would allow monitoring the risk of subclinical ...

Breath Analysis for Early Detection of Rising Ketone Bodies in Postpartum Dairy Cows Classified as at Risk of Ketosis

open access: yesRuminants, 2023
Ketosis is a metabolic disorder associated with high production and low energy intake in dairy cows. Fat reserves are mobilized, and gluconeogenesis occurs.

Microbial acetone oxidation in coastal seawater [PDF]

open access: yes, 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 ...

Ternary Hybrid Materials for Highly Sensitive Acetone Sensing at Room Temperature

open access: yesCrystals, 2023
The performance of a conventional metal oxide sensor (MOX) is highly dependent on its high operating temperature. Many researchers have tried to solve the problem by exploring hybrid materials.

Breath acetone concentration decreases with blood glucose concentration in type I diabetes mellitus patients during hypoglycaemic clamps [PDF]

open access: yes, 2009
Conventional wisdom is that breath acetone may be markedly elevated in type 1 diabetes, but that this only occurs during poor blood glucose control and/or intercurrent illness.

Acetone as Indicator of Lipid Oxidation in Stored Margarine

open access: yesAntioxidants, 2021
Margarine contains a minimum of 80% fat and is therefore prone to lipid oxidation. While lipid oxidation in vegetable oils and o/w emulsions has been thoroughly investigated, studies about the oxidative stability and the identification of potential ...
