The biodegradable cellulose-derived polyol and polyurethane foam

open access: yesPolymer Testing, 2021
The method of polyol synthesis from cellulose, glycidol, and ethylene carbonate in water was elaborated. The obtained polyol was characterized by IR, 1H NMR and MALDI ToF spectroscopy. The polyol was then used to obtain rigid polyurethane foam. That foam

Fast and Selective Degradation of Biomass for Xylose, Glucose and Lignin under Mild Conditions

open access: yesMolecules, 2023
The conversion of lignocellulose into valuable chemicals has been recognized as the key technology in green chemistry. However, selective degradation of hemicellulose and cellulose with the production of lignin is still a challenge. Therefore, a two-step

Synthesis and characterization of different soybean oil-based polyols with fatty alcohol and aromatic alcohol

open access: yese-Polymers, 2021
In this article, five kinds of soybean oil-based polyols (polyol-E, polyol-P, polyol-I, polyol-B, and polyol-M) were prepared by ring-opening the epoxy groups in epoxidized soybean oil (ESO) with ethyl alcohol, 1-pentanol, isoamyl alcohol, p-tert ...

Room Temperature Surfactant-Free Synthesis of Gold Nanoparticles in Alkaline Ethylene Glycol

open access: yesChemistry, 2023
Gold nanoparticles are easily obtained by a range of room temperature processes. In particular, polyols-based syntheses performed in alkaline conditions without the need for surfactants lead to small size nanoparticles around 10 nm in diameter.

Development of curcumin liposome formulations using polyol dilution method [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2016
This study was aimed to formulate curcumin liposomes (CLs) by using polyol dilution method which is advantageous for no residue of organic solvent. CLs were the mixture of hydrogenated phosphatidylcholine (PC) and cholesterol (CH) at the molar ratio of

The Quenching and Sonication Effect on the Mechanical Strength of Silver Nanowires Synthesized Using the Polyol Method

open access: yesMolecules, 2021
This study aims to determine the effect of fast cooling (quenching) on thermal properties, mechanical strength, morphology and size of the AgNWs. The synthesis of AgNWs was carried out at three different quenching-medium temperatures as follows: at 27 °C
