Diformylxylose as a new polar aprotic solvent produced from biomass

— Xylose-derived diformylxylose (DFX) can be produced in a single step from biomass. In our paper published in Green Chemistry, we show that DFX can act as a novel polar aprotic bio-based solvent similarly to DMF, NMP, and DMSO in alkylation, cross-coupling, and hydrogenation reactions. We demonstrate that DFX possesses unique solvation properties — high polarity and high hydrogen-bond accepting ability. Physical properties of DFX such as high boiling (237°C) and melting point (48°C) indicate a lower risk of human exposure and the environmental impact due to low volatility. Finally, toxicological assessment shows that DFX is a non-mutagenic and non-carcinogenic molecule. Overall, low production cost, high performance, non-mutagenic nature, and renewability make DFX a promising bio-based alternative to traditional polar aprotic solvents.

Modeling of enzymatic hydrolysis of lignocellulosic biomass

— Understanding how the digestibility of lignocellulosic biomass is affected by its morphology is essential to design efficient processes for biomass deconstruction. In this study, we used a model based on a set of partial differential equations describing the evolution of the substrate morphology to investigate the interplay between experimental conditions and the physical characteristics of biomass particles as the reaction proceeds. Our model carefully considers the overall quantity of cellulase present in the hydrolysis mixture and explores its interplay with the available accessible cellulose surface.

Seongmin Jin joins the lab

— Seongmin obtained his Bachelor's and Ph.D. degrees in Chemical and Biomolecular Engineering from Yonsei University. He worked on the development of metal oxide composites for CO2 capture and water-gas shift reaction. In LPDC, his work focuses on developing atomic-layer-deposited metal oxides for CO2 hydrogenation.
