Some Atypical Properties of Beryllium Compounds - …
Some simple background Although beryllium does not normally form a simple ion such as Be 2 +, it does form ions in solution. When solvated, the beryllium ion attaches to four water molecules, forming a complex ion with the formula [Be(H 2 O) 4] 2+.
Micromachines | Free Full-Text | Demonstration of a …
Silicon carbide is a semiconductor which possesses extreme resistance to corrosive chemistries, experiences only limited oxidation, and has demonstrated no appreciable toxicity [65,66,67,68]. We have demonstrated that hexagonal silicon carbide junction isolation electrode devices have a much higher forward bias turn-on potential than Si (2.3 V vs. 0.7 V).

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. Our result explains the distinctive optical properties in porous polycrystalline and nanocrystalline 3C-SiC and reveals the crucial conditions for quantum confinement photoluminescence to arise.
