Researchers have developed nanostructures that enable record-breaking conversion of laser pulses into high-harmonic generation, paving the way for new scientific tools for high-resolution imaging and studying physical processes that occur at the scale of an attosecond - one quintillionth of a second.
Using an inkjet printer with conductive nano ink to draw a circuit on the polymeric thin film, it is possible to create a device that emits light and energy locally, with promising applications in medical treatment.
