One-pot synthesis of highly ordered SBA-15 type silica-tethered phosphonic acid at weakly acidic pH (3.75) allows for higher loading of phosphonic functionality (up to 33%) without significant deterioration of the mesostructure. In this synthesis sodium metasilicate was used instead of tetraethylorthosilicate. The resulting samples featured high specific surface areas (362–533m2/g) and well-developed...
The binding interaction between polyethylene glycols (PEG) and sodium dodecyl sulfate (SDS) was examined by isothermal titration calorimetric (ITC) technique. For PEG with molecular weight of 7000–8000Da, unusual ITC profile attributed to the structural reorganization of SDS/PEG aggregates was observed. The basic binding segment for PEG was found to be close to an averaged molecular weight of ∼4000Da...
