Ultrasound-assisted esterification of levulinic acid for sustainable butyl levulinate production over tin(II)-modified silicotungstic acid supported on activated bentonite

Leveraging ultrasound irradiation and Brønsted–Lewis acid synergy, butyl levulinate (BL), a promising bio-based fuel additive, was synthesized by esterifying levulinic acid (LA) with n -butanol over tin(II)-modified silicotungstic acid supported on activated bentonite (Sn x STA/a...

A modelling study of nonlinearity of the cross-shore flow under breaking waves

Abstract A new process-based modelling framework is used to simulate wave-driven flows over a bar in the large-scale SINBAD and LIP11-1C experiments, representing high- and low-wave conditions, respectively. The framework couples an open-source Boussinesq wave model with a one-di...
