On the Ideal Diamagnetism of Composite Graphene and Graphite Nanostructures

Rzhevskii A., Chahid S., Dulal R., Teknowijoyo S., Gulian A., Thermo Fisher Scientific, US

Graphite and its derivatives such as graphene have demonstrated many unique properties that are still un- der intense exploration. In particular, these properties are important for microelectronics applications. In our case it was ideal diamagnetism [...]

Raman Imaging for Characterization of Novel Multi-Layer Solid Dosage Forms

Rzhevskii A., Thermo Fisher Scientific, US

Multi-layer tablets, combination drug formulations and other innovative dosage forms are getting increasing attention in pharmaceutical industry. As structure and composition of the multi-layer dosages become more complicated, the development and application of techniques for [...]

Characterization of Microcrystalline and Amorphous Thin Film Silicon Devices with Raman Spectroscopy

Wall M., Hodkiewicz J., Thermo Fisher Scientific, US
