Latest Patents

Wickramasinghe's latest patents include innovative solutions for treating fracking wastewater and methods for producing hydroxymethylfurfural (HMF). The first patent describes bilayer electrospun membranes designed for treating hydraulic fracking wastewater via membrane distillation. This technology features an omniphobic layer that prevents low-surface tension solution wicking and an oleophobic antifouling surface to minimize foulant deposition. The membranes are enhanced with nanoparticles that are decorated on the omniphobic surface through electrochemical interaction, coated with a fluorine monomer. Additionally, a zwitterionic co-polymer is grafted using self-assembly techniques to improve the antifouling properties of the membrane.

The second patent focuses on the catalytic hydrolysis and dehydration of saccharides. This method involves providing a saccharide feedstock, such as glucose, and bringing it into contact with a solid-state catalytic structure. The structure is designed to facilitate the dehydration of glucose to produce HMF, utilizing functionalized surfaces that enhance saccharide solubilization and acid functionalities.
