A proposed greener approach for extraction of PHAs in comparison to methods using hazardous solvent.
Hydrophobic deep eutectic solvents (DESs), a recent class of green solvents, offer 100% atom economy, low cost, potential biodegradability, negligible toxicity and promising bioactivities. In this work, novel aroma-based therapeutic hydrophobic DESs were prepared dispersed in aqueous media as nanoemulsions to potentiate biomedical applications, where polar is encountered. A reusable microengineered stainless-steel isoporous membrane was fabricated by laser drilling technique. Three DESs,...
Membrane-based gas separation is a promising unit operation in low-carbon economy due to its simplicity, ease of operation, reduced energy consumption and portability. A methodology proposed immobilise enzymes stable water-in-oil (W/O) emulsions produced by direct membrane emulsification systems thereafter impregnated them the pores producing emulsion-based supported liquid membranes. The selected case-study was for biogas (CO2 CH4) purification. Upon initial CO2 sorption studies, corn oil...
Highlights•Chitosan, a biocompatible biopolymer, was used to prepare particles.•Direct membrane emulsification produce Gas-in-water-in oil double emulsion.•Produced 7 μm porous particle showed up 95 % of protein (BSA) entrapment.•Kinetics BSA release studied for different formulated particles.AbstractIn drug delivery, it is common use particles as carrier media, instead dense particles, due their high specific surface area and available entrapment volume, which allows higher amount be...
Membrane-based gas separation is an important unit operation in chemical industries due to its simplicity, ease of operation, reduced energy consumption, and compact structure. For separation, novel studies were carried out by synthesising enzyme-stabilised systems consisting emulsion-based supported liquid membranes (E-SLMs) the pores which impregnated with water-in-oil (W/O) emulsions produced direct membrane emulsification. This technique has gained attention, as it consumes low mild...
