Thermodynamic Stability of Clusters of Molybdenum Oxide [PDF]

open access: yesLangmuir, 2004
We show that a single geometrical rule underlies the stability of "polyoxomolybdates", the variety of clusters of molybdenum(VI) oxide in (acidified) aqueous solution that are found experimentally. We predict that upon increasing the proton or total molybdenum oxide concentration, the average size of the clusters increases.

Oxidative stability of hake liver oil

open access: yesGrasas y Aceites, 1993
Oxidative stability of industrial hake liver oil and its improvement by means of antioxidants were studied. For this purpose the induction period (hours) was determined in a Rancimat (70°C, air flow 8.3 l/h and 5 g sample). The antioxidants employed were

Oxidative Quality of Acid Oils and Fatty Acid Distillates Used in Animal Feeding

open access: yesAnimals, 2021
Acid oils (AO) and fatty acid distillates (FAD) are byproducts from chemical and physical refining of edible oils and fats, respectively. Their high energy value makes their upcycling interesting as alternatives to conventional fats in animal feeding ...

Oxidative stability of rice bran, corn, canola, sunflower and soybean oils d baking process and storage of bread [PDF]

open access: yesBihdāsht-i Mavādd-i Ghaz̠āyī, 2016
Oxidation of bread lipids during baking and storage reduces the nutritional value of the product and leads to the formation of off-flavors and off-odors.
