A naked flame is a complex soup of ionised gases, that possesses an unexpected property. As you might expect with that much ionisation there is some level of electrical conductivity, but the unusual ...

Since the backlight of the LCD panel in a smartphone accounts for around 40% of the device’s total power consumption, one can benefit greatly by adjusting the brightness in response to changes in ...

Engineers in Switzerland have built light-emitting diodes so small that hundreds could line up across the width of a single ...

The first light-sensing system that reconstructs human postures continuously and unobtrusively has been developed by scientists, furthering efforts to create smart spaces in which people control their ...

Micro-light-emitting diodes (μLEDs) have garnered significant interest as light sources for gas sensors due to their advantages, such as room temperature operation and low power consumption. However, ...
