Selective photoelectrochemical oxidation of glycerol to high value-added dihydroxyacetone

open access: yesNature Communications, 2019
It is highly profitable to transform glycerol – the main by-product from biodiesel production to high value-added chemicals. In this work, we develop a photoelectrochemical system based on nanoporous BiVO4 for selective oxidation of glycerol to 1,3 ...

Esterification of Free Fatty Acids with Glycerol within the Biodiesel Production Framework [PDF]

open access: yes, 2019
Companies in the field of the collection and treatment of waste cooking oils (WCO) for subsequent biodiesel production usually have to cope with high acidity oils, which cannot be directly transformed into fatty acid methyl esters due to soap production.

Platinum–copper single atom alloy catalysts with high performance towards glycerol hydrogenolysis

open access: yesNature Communications, 2019
Selective hydrogenolysis of biomass-derived glycerol to propanediol is an important reaction to produce high value-added chemicals but remains a big challenge.

Green Synthesis of Silver Nanoparticles with Size Distribution Depending on Reducing Species in Glycerol at Ambient pH and Temperatures

open access: yesACS Omega, 2020
With an increase in biodiesel demand, a large surplus of glycerol is expected, and there is interest regarding the usage of glycerol as a value-added product.

A robust comparison of dynamical scenarios in a glass-forming liquid [PDF]

open access: yes, 2016
We use Bayesian inference methods to provide fresh insights into the sub-nanosecond dynamics of glycerol, a prototypical glass-forming liquid. To this end, quasielastic neutron scattering data as a function of temperature have been analyzed using a ...

Isolation and characterization of monoacetyldiglycerides from bovine udder

open access: yesJournal of Lipid Research, 1999
Monoacetyldiglycerides (MADGs) were isolated from an animal tissue, bovine udder, by solvent extraction and silica gel column chromatography. Monoacetyldiglyceride structures were identified using a variety of 1-D and 2-D NMR techniques and collision ...

Phase Equilibrium and Optimization Tools: Application for Enhanced Structured Lipids for Foods [PDF]

open access: yes, 2011
Solid-liquid phase equilibrium modeling of triacylglycerols mixtures is essential for lipids design. Considering the α polymorphism and liquid phase as ideal, the Margules 2-suffix excess Gibbs energy model with predictive binary parameter correlations ...

Photophysics, Molecular Reorientation in Solution and X-Ray Structure of a New Fluorescent Probe 1,7-Diazaperylene [PDF]

open access: yes, 1993
A new fluorescent molecule 1,7-diazaperylene (DP) has been investigated by means of time-resolved and steady-state polarized fluorescence spectroscopy, as well as X-ray spectroscopy.

Copper-Catalyzed Asymmetric Sulfonylative Desymmetrization of Glycerol

open access: yesMolecules, 2022
Glycerol is the main side product in the biodiesel manufacturing process, and the development of glycerol valorization methods would indirectly contribute the sustainable biodiesel production and decarbonization.

Superlubricity mechanism of diamond-like carbon with glycerol. Coupling of experimental and simulation studies [PDF]

open access: yes, 2007
We report a unique tribological system that produces superlubricity under boundary lubrication conditions with extremely little wear. This system is a thin coating of hydrogen-free amorphous Diamond-Like-Carbon (denoted as ta-C) at 353 K in a ta-C/ta-C ...
