Investigation of surfactant-drug pharmacokinetic interactions
… surfactants and a bile salt, namely Brij® 58, Tween® 20, Span® 20, Cremophor® CO40 and sodium deoxycholate. The surfactants were added at three different concentrations, 0.1%, 0.5% and 1.0% (w/v), to investigate if the addition of these surfactants had any influence on the membrane permeability …

Natural antimicrobial nanomaterials for food packaging applications
… OEOs, the effects of different surfactants (Tween® 20 and Pluronic™ 127), the surfactant to oil ratio (2:1, 1:1, and 1:2) and physical treatments (untreated, IKA ultra-turrax or tip-sonication) on the physical properties of the nanoemulsions was evaluated. The antimicrobial activity of the …

Tools for improving and understanding microbial performance in biorenewable applications
… We developed an emulsion formulation composed of Tween®20, Span®80, and a lignin-rich fraction of pyrolyzed biomass which enables P. putida KT2440 to grow in a lignin-rich fraction of pyrolytic bio-oil. This type of emulsion could be applied for microbial conversion of lignin-rich feedstocks to …

Investigating variables affecting heap (bio)leaching through determining access to sub-surface mineral grains by micro-scale X-ray tomography
… Based on the results of these experiments, Tween® 20 (10 mg L -1 ) was selected to study the effect of surfactant on non-surface mineral grain leaching in the mini-columns. Each column was scanned by X-ray μCT at 100 kV and 150 mA using a 0.38 mm copper filter and at a distance of 59.40 mm …
