The atomic structure of the material strontium vanadate (strontium vanadate) - illustration of the atomic structure of the material under tension (right) and compression (left). In the center you can see the true atomic arrangement in the material in an electron microscope image. At the bottom of the picture you can see how the various efforts change the structure of the energy levels in the material and therefore also the way the electrons arrange themselves in it. By controlling these properties, the researchers intend to engineer these materials into future transistors. Photo: Nitzan Zohar, Technion Spokesperson

The silicone sheet as it appears before it is wrapped around the heart or nerve tissue. The colors you see are due to the porosity of the surface - nanoholes that refract and absorb the different wavelengths of light in an inhomogeneous manner, which causes the different colors of the rainbow to appear.
