Box–Behnken optimization and ANN‐ANFIS integrated modelling for transesterification using thermally activated basic oxygen furnace slag catalyst

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Global energy demand and environmental concerns have intensified the search for renewable and sustainable energy sources. This study thus, focuses on optimizing the transesterification process of waste cooking oil (WCO) using thermally activated basic oxygen furnace slag catalyst calcined at 850°C (BOF 850). The optimization and modelling were

Sustainable Hydrogen Production by Glycerol and Monosaccharides Catalytic Acceptorless Dehydrogenation (AD) in Homogeneous Phase

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...

Whey proteins interact with lipids during autoxidation primarly via the production of reactive carbonyl species [PDF]

, 2010
Nowadays, it is well recognized that polyunsaturated fatty acids (PUFAs) can provide extensive nutritional and health benefits. Thus, ω-3 PUFAs have been considered to contribute to the prevention of several diseases.

Effect of heat treatment of canola seed and its meal on nutrients degradability, ruminal fermentation, and ruminal biohydrogenation of unsaturated fatty acids using rumen simulation technique (Rusitec)

Open Veterinary Journal
Background: One possible method to improve ruminant nutrient utilization is heat treatment of feed ingredients, such as canola seed and its meal, to reduce ruminal degradation of proteins and unsaturated fatty acids (UFA). Aim: The study evaluate the

Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.
Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.

Photochemical Decatungstate‐Catalyzed Hydroacylation of Maleimides

European Journal of Organic Chemistry, EarlyView.
A photocatalytic protocol to access substituted succinimides via tetra‐n‐butylammonium decatungstate photocatalysis is reported. This direct radical‐driven hydroacylation of a variety of N‐substituted maleimides shows tolerance to various aldehydes (or alkanes), affording differentially substituted succinimides in high yields. Succinimides constitute a
