Understanding the Chemical and Electronic Properties of Sub‐Monolayer TiO2 on High Surface Area Silica for Jet Fuel Synthesis Applications

Advanced Functional Materials, Volume 36, Issue 1, 2 January 2026.
Sub‐monolayer titania grafted onto mesoporous silica enables solvent‐free photocatalytic upgrading of furfural and cyclopentanone into jet fuel precursors. Advanced spectroscopic methods reveal tunable surface speciation, acidity, and bandgaps, enhancing catalytic efficiency.

Challenges in lignin valorization during biomass hydrogenolysis for ethylene glycol production

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 1, Page 268-279, January/February 2026.
Abstract This study examined the extent to which lignin upgrading is possible when maximizing ethylene glycol (EG) production during the hydrogenolysis of lignocellulosic biomass over bifunctional tungsten–nickel catalysts. Reductive catalytic fractionation (RCF) was selected as a benchmark lignin valorization process because its reaction conditions ...

Uncoupling human and climate drivers of late Holocene vegetation change in southern Brazil [PDF]

, 2018
In the highlands of southern Brazil an anthropogenitcally driven expansion of forest occurred at the expense of grasslands between 1410 and 900cal BP, coincident with a period of demographic and cultural change in the region.
