A Bottom-Up Approach for the Synthesis of Highly Ordered Fullerene-Intercalated Graphene Hybrids

*Correspondence: Dimitrios Gournis, Department of Materials Science and Engineering, University of Ioannina, Ioannina 45110, Greece e-mail: [email protected] Much of the research effort on graphene focuses on its use as a building block for the development of new hybrid nanostructures with well-defined dimensions and properties suitable for applications such as gas storage, heterogeneous cataly...

Bottom-Up Construction of Ontologies

We present a particular way of building ontologies that proceeds in a bottom-up fashion. Concepts are defined in a way that mirrors the way their instances are composed out of smaller objects. The smaller objects themselves may also be modeled as being composed. Bottom-up ontologies are flexible through the use of implicit and, hence, parsimonious part-whole and subconceptsuperconcept relations...

Highly ordered cubic mesoporous electrospun SiO2 nanofibers.

Cubic (Im3[combining macron]m) mesoporous silica nanofibers were successfully prepared using a new F127-PVA-SiO2 tri-constituent assembly approach by the electrospinning technique. PVA was used to protect the F127 directed cubic micelles which usually deform during electrospinning. The preformed Au NPs can be loaded inside the mesopores of the nanofibers.

Molecular rotors in hierarchically ordered mesoporous organosilica frameworks.

Diphenylene moieties, molecularly ordered in the framework of periodic mesoporous organosilicas, behave as molecular rotors and show a mobility with correlation times as short as a few nanoseconds.
