Sulfonated sporopollenin as an efficient and recyclable heterogeneous catalyst for dehydration of D-xylose and xylan into furfural [PDF]

open access: yes, 2016
The natural acidity of sporopollenin, the biopolymer coating the outer walls of pollen grains, was enhanced by the sulfonation of its surface. Modified sporopollenin displaying sulfonic acid groups has been prepared, characterized by elemental analysis ...

Slow Release of Bioactive Alcohols From Butenolide Polymers and Coatings

open access: yesChemistry – A European Journal, EarlyView.
In this study we have reported the acid‐mediated release of bioactive alcohols from biobased alkoxy butenolide derived copolymers and coatings. It can potentially be applied for slow release of odors, pesticides, or drug‐related compounds from biobased polybutenolides.

Harnessing Acoustic Cavitation Energy for the Selective Degradation of Impurities in Glucose Syrup

open access: yesChemistry – A European Journal, EarlyView.
The energy released during the implosion of acoustic cavitation bubbles can be harnessed and selectively transferred to a target solute, enabling its specific decomposition without degrading other solutes present in the solution. This proof of concept was demonstrated in the degradation of impurities present in trace amount in glucose syrup.

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...
