We characterize individual Ag-TCNQ nanocrystals during switching their resistivity state in operando. Raman and soft X-ray absorption microspectroscopy are employed to disclose the electronic state of the organic component in dependency of applied voltage. Whereas Raman microspectroscopy offers qualitative insight into the conversion of negatively charged TCNQ molecules to their neutral counter...

This paper deals with a comprehensive survey on the topic of AC/DC & DC/DC converters for DC Motor Drives. A substantial number of different AC/DC and DC/DC topologies appropriate for DC motor drives are presented. This critical literature review brings out merits, demerits, and limitations besides giving the basic operating principles of various topologies. Keywords—controlled-rectifiers, chop...
