Recently many ideas have been proposed for the use of a longitudinal field for particle
acceleration, fluorescent imaging, second-harmonic generation and Raman spectroscopy. A few …

Gold nanorods excited at 830 nm on a far-field laser-scanning microscope produced strong
two-photon luminescence (TPL) intensities, with a cos 4 dependence on the incident …

Lithium cobalt oxide, presently the most widely used cathode (positive electrode) intercalation
compound in lithium-ion rechargeable batteries, is considered to be highly stable in the-…

The upgrading of plastic waste is one of the grand challenges for the 21 st century owing to
