Online investigation of lignin depolymerization via reactor-integrated electrospray ionization high-resolution mass spectrometry

open access: yesApplications in Energy and Combustion Science, 2022
Depolymerization of lignin can yield phenolic monomeric platform molecules, but depolymerization and repolymerization are proposed as concurrent processes, which greatly limit the yield of monomeric products.

Antiviral Activity of Carrageenans and Processing Implications

open access: yesMarine Drugs, 2021
Carrageenan and carrageenan oligosaccharides are red seaweed sulfated carbohydrates with well-known antiviral properties, mainly through the blocking of the viral attachment stage. They also exhibit other interesting biological properties and can be used

Fiber Depolymerization [PDF]

open access: yesBiophysical Journal, 2006
Depolymerization is, by definition, a crucial process in the reversible assembly of various biopolymers. It may also be an important factor in the pathology of sickle cell disease. If sickle hemoglobin fibers fail to depolymerize fully during passage through the lungs then they will reintroduce aggregates into the systemic circulation and eliminate or ...

Hydrogenative Depolymerization of Nylons [PDF]

open access: yesJournal of the American Chemical Society, 2020
The widespread crisis of plastic pollution demands discovery of new and sustainable approaches to degrade robust plastics such as nylons. Using a green and sustainable approach based on hydrogenation, in the presence of a ruthenium pincer catalyst at 150 °C and 70 bar H2, we report here the first example of hydrogenative depolymerization of ...

Application of Electrical Breakdown in Liquid Process on Inulin Structural Transformations

open access: yesIEEE Access, 2023
This work proposes a novel technique for biological compound transformation by a circulating electrical breakdown in the liquid (EBL) process. The EBL reactor has been designed with a cylindrical, hourglass-shaped structure that facilitates plasma ...

Pyrolytic Conversion of Cellulosic Pulps from “Lignin-First” Biomass Fractionation

open access: yesEnergies, 2023
Utilization of lignin is among the most pressing problems for biorefineries that convert lignocellulosic biomass to fuels and chemicals. Recently “lignin-first” biomass fractionation has received increasing attention.

Degradation of pretreated agroforestry residues by selected micromycetes [PDF]

open access: yesZbornik Matice Srpske za Prirodne Nauke, 2022
Nowadays, there are huge amounts of lignocellulosic materials left in agroforestry practice, which can be transformed into useful products. Biomass exploitation could be aiming not only at replacing conventional energy sources but also at ...
