Read moreMicroscopy pencils patterns in polymers at the nanoscale
Scientists have used advanced microscopy to carve out nanoscale designs on the surface of a new class of ionic polymer materials for the first time. The study provides new evidence that atomic force microscopy, or AFM, could be used to precisely fabricate materials needed for increasingly smaller devices.

Read moreDiscovery opens door for radical reduction in energy consumed by digital devices
A new paper describes the first direct observation of a long-hypothesized but elusive phenomenon called 'negative capacitance'. The work describes a unique reaction of electrical charge to applied voltage in a ferroelectric material that could open the door to a radical reduction in the power consumed by transistors and the devices containing them.

Read morePyramid nanoscale antennas beam light up and down
The new antennas look like pyramids, rather than the more commonly used straight pillars. The pyramid shape enhances the interference between the magnetic and electric fields of light. This makes the pyramid-shaped antenna capable of enhancing light emission and beaming different colours of light towards opposite directions.
