Effective conversion of fructose to 5-ethoxymethylfurfural with brønsted acid site (S/Cl)-functional carbon catalysts

open access: yesJournal of Bioresources and Bioproducts, 2022
Brønsted acid site (S/Cl)-functional carbon materials were prepared by ball-milling (bm) L-cysteine and ammonium chloride to form chemical complex solids, by post-heat treatment (Q) of the solids at 500 °C under a nitrogen gas atmosphere to stabilize and

Electrodeposition from supercritical fluids

open access: yes, 2014
Recent studies have shown that it is possible to electrodeposit a range of materials, such as Cu, Ag and Ge, from various supercritical fluids, including hydrofluorocarbons and mixtures of CO2 with suitable co-solvents. In this perspective we discuss the
