A newly-developed form of transistor opens up a range of new electronic applications including wearable or implantable devices by drastically reducing the amount of power used. Devices based on this type of ultralow power transistor could function for months or even years without a battery by 'scavenging' energy from their environment.
Flooring can be made from any number of sustainable materials, making it, generally, an eco-friendly feature in homes and businesses alike. Now, flooring could be even more 'green', thanks to an inexpensive, simple method that allows engineers to convert footsteps into usable electricity.
The amount of light passing through an opaque layer, can be enhanced using smart techniques. At the same time, the amount of reflected light diminishes, researchers show. It's as if light speckles have a conversation of their own.
Photodetectors are typically only sensitive to light within a certain narrow bandwidth, which causes numerous problems to product developers. Now, researchers have found a way to address this by treating an ordinary photodetector with UV light can turn it into a high bandwidth device.
A diagnosis of pancreatic cancer is often a death sentence because chemotherapy and radiation have little impact on the disease. But new research could eventually lead to a new type of treatment based on gold nanoparticles.
Scientists were able to produce subnatural-linewidth biphotons from a Doppler-broadened hot atomic vapour cell. This method marks a significant breakthrough in the field, as it greatly simplifies production process of narrowband biphotons.
