Synchrotron small angle X-ray scattering for the evaluation of the interaction of silica nanotubes with lipid membranes

Synchrotron X-ray scattering measurements were used to assess the interaction of silica nanotubes (SNTs) with membrane model systems in conditions that mimic the physiological pH of healthy (pH 7.4) and pathological (pH 5.0) cellular membranes. SNT arrays were synthesized combining the sol-gel method with a porous anodic alumina (PAA) template assisted approach. The inner surfaces of the SNTs were functionalized with aminopropylethoxysilane (APTES). Scanning electron microscopy (SEM) and tran...

A PDF based digital signed document format for interoperable institutional structured data integrity

It is widely recognized that information systems constitute a key tool for the overall performance improvement of administrative tasks in academic institutions. However at their genesis lies a latent promise of a paper-less environment that stays most of the time unfulfilled due to the lack of appropriate digital document integrity and accountability mechanisms. Academic institutions are thus most of the time still relying on traditional security trust methods based on paper documents for sig...
