Ultrasmall silicon carbide nanoparticles (SiC USNPs) are very promising biomarkers for developing new appliions in diagnostics, cell monitoring or drug delivery, even though their interaction with biological molecules such as different proteins has not yet been

The Quartz Page: Quartz Structure

To get an idea of quartz crystal structure and its symmetry properties, most figures show the crystal when viewed in the direction of either the a-axis or the c-axis (a and c in Fig.1.01). This corresponds to a projection of the atoms onto the a-plane and the c-plane, and not to a slice of the crystal: the atoms one sees actually lie in different planes along the a- and the c-axis.

Microstructure and infrared spectral properties of porous …

The 3C-SiC crystallites with an average size of 4 nm showed simple surface chemistry with the surfaces well passivated by dissociation of surrounding water molecules.
