Relationship between cationic charge, coordination number, and polarizability in oxidic materials
Article Abstract:
An investigation made into the variation of oxide(-II) electronic polarizability, alpha(sub oxide(-II)), for glasses covering a wide range of composition shows that there is an almost linear relationship between alpha(sub oxide(-II)) and glass basicity expressed as optical basicity, lambda. Data for glasses containing the cations indicate that the oxide(-II) atoms of the glass undergo the same degree of polarization regardless of whether these cations exercise a coordination number of four or six.

Electrofluorescence of MEH-PPV and its oligomers: Evidence for field-induced fluorescence quenching of single chains
Article Abstract:
Optical and electronic properties of poly[2- methoxy-5-(2-ethylhexyloxy)-p-phenylenevinylene] (MEH- PPV) and a series of oligomeric model compounds using electroabsorption and electrofluorescence spectroscopy are studied. Evidence of electric-field-induced fluorescence quenching of MEH-PPV in dilute solvent glasses is found.

Multiple mechanical relaxations in ethylcyclohexane above the glass transition temperature
Article Abstract:
The investigation of the mechanical response of ethylcyclohexane at ultrasonic frequencies in a large temperature range from 300 K down to the glass transition region is presented. It exhibited three different mechanical relaxations above the glass transition temperature.
