A German-polish research team from Augsburg, Münster, Munich and Wrocław successfully mixed nanoscale sound waves and light quanta. In their study published in Optica the scientists use an ’artificial atom’ that converts the vibrations of the sound wave to single light quanta - photons - with unprecedented precision.
Driving at night is one significant cause of accidents, making the vehicle's headlights and forward-facing illumination particularly important for a safe journey. Adaptive driving beam (ADB) technology,
The charge stability of electret materials can directly affect the performance of electret-based devices such as electrostatic energy harvesters. In this paper, a spray-coating method is developed to deposit an electret layer with enhanced charge stability.
to use a standard dielectric material called bisbenzocyclobutene (BCB), along with conventional wafer bonding equipment. "We basically glue the two wafers together with a resin made of BCB," he says.
