Use of Ionic Liquids and Co-Solvents for Synthesis of Thin-Film Composite Membranes
Membranes, 2021 Polyamide (PA) thin-film composite (TFC) membranes are commonly applied in reversed osmosis (RO) and nanofiltration (NF) applications due to their thin, dense top-layer, and high selectivity. Recently, the conventional organic phase (i.e., hexane) during

Journal of Catalysis, 2018 Chemical looping epoxidation of ethylene was demonstrated, whereby the sole oxidant was a solid oxygen carrier, 15 wt% Ag supported on SrFeO3. Ethylene reacted with a bed of carrier particles, without any O2(g) in the feed, to produce ethylene oxide (EO) and CO2.

Structure and Chemistry of Graphene Oxide in Liquid Water from First Principles [PDF]
Nature Communications, 2020, 11, 1566, 2019 Graphene oxide is a rising star among 2D materials, yet its interaction with liquid water remains a fundamentally open question: experimental characterization at the atomic scale is difficult, and modelling by classical approaches cannot properly describe chemical reactivity.

Ag-Cu alloy surfaces in an oxidizing environment: a first-principles study [PDF]
, 2008 Recent experiments on model catalysts have shown that Ag-Cu alloys have improved selectivity with respect to pure silver for ethylene epoxidation. In this paper we review our first-principles investigations on the (111) surface of this alloy and present new findings on other low index surfaces.

Divinylglycol, a Glycerol-Based Monomer: Valorization, Properties, and Applications [PDF]
Green Polymer Chemistry: New Products, Processes, and
Applications, pp.299-330, 2018, 2019 In the context of the development of bio-refineries, glycerol and its derivatives are co-products of the oleochemistry for which new valorization routes must be found. In this study, the polymerizability of divinylglycol (DVG), a symmetrical C-6 glycerol derivative which bears a vicinal diol and two vinyl functions was studied.
