The energy density of supercapacitors – battery-like devices that can charge in seconds or a few minutes – can be improved by increasing the ‘messiness’ of

Using Artificial Intelligence (AI) to replace optical and mechanical components, researchers have designed a tiny spectrometer that breaks all current

Scientists have designed an ultra-miniaturised device that could image single cells without the need for a microscope or make chemical fingerprint analysis possible from within a smartphone camera.
