Artist’s impression of an array of nanomechanical resonators designed to generate and trap sound particles, or phonons. The mechanical motions of the trapped phonons are sensed by a qubit detector, which shifts its frequency depending on the number of phonons in a resonator. Different phonon numbers are visible as distinct peaks in the qubit spectrum, which are shown schematically behind the resonators. (Image credit: Wentao Jiang)

Counting sound particles with quantum microphone

Now it is possible to measure individual particles of sound, called phonons- thanks to Stanford Scientists who developed quantum microphone. The quantum microphone is...

Scientists discovered the source of strange negative gravity

The objects' motion we see in our everyday lives are governed by Newton's Laws of Motion and gravity. But according to scientists at the...
Diagram illustrates the crystal lattice of a proposed battery electrolyte material called Li3PO4. The researchers found that measuring how vibrations of sound move through the lattice could reveal how well ions – electrically charged atoms or molecules – could travel through the solid material, and therefore how they would work in a real battery. In this diagram, the oxygen atoms are shown in red, the purple pyramid-like shapes are phosphate (PO4) molecules. The orange and green spheres are ions of lithium.

A novel way to find better battery materials
