Clay–gemini surfactant hybrid materials for elimination of inorganic pollutants: A comprehensive review

Results in Chemistry, 2022
Though organoclays modified with gemini surfactants are one of the ubiquitous adsorbents due to their enlarged interlayer spacing, modified surface characteristic and hydrophobic property, its usage for elimination of inorganic pollutants is still at a ...

New cationic nanovesicular systems containing lysine-based surfactants for topical administration: Toxicity assessment using representative skin cell lines [PDF]

, 2013
Many strategies for treating diseases require the delivery of drugs into the cell cytoplasm following internalization within endosomal vesicles. Thus, compounds triggered by low pH to disrupt membranes and release endosomal contents into the cytosol are ...

In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols

FEBS Open Bio, EarlyView.
Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,

Technical approaches for optimizing the effectiveness of Gemini surfactants in enhanced oil recovery: a structural review

Discover Chemistry
Gemini surfactants constitute a unique class of amphiphilic molecules in which two or more conventional surfactant moieties are covalently connected through a spacer positioned at or near their hydrophilic head groups. Compared to traditional surfactants,
