The nitrogen adsorption isotherm measured at 77 K in the relative pressure range from about 5 × 10-7 to 0.988 for a macroporous silica is reported in a tabular form. The isotherm data are in good agreement in the high-pressure range with the reference data published by Gregg and Sing and by Kiselev and Aristov and provide an extension of the latter data to the low-pressure region, for which a ...

Synthesis of Monodisperse, Rodlike Silica Colloids with ...

Although the experimental study of spherical colloids has been extensive, similar studies on rodlike particles are rare because suitable model systems are scarcely available. To fulfill this need, we present the synthesis of monodisperse rodlike silica colloids with tunable dimensions. Rods were produced with diameters of 200 nm and greater and lengths up to 10 μm, resulting in aspect ratios ...
