Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
A synthetic crystal that can manipulate or be sensitized to respond to specific wavelengths of light. Its development suggests the possibility of increased miniaturization and efficiency of computing components and other technologies.
- ‘Musevic and his colleagues believe that crystal bridges might someday connect microscopic beads in a lattice structure that would reflect or transmit certain wavelengths of light - a so-called photonic crystal.’
- ‘But getting light in and out of them has been a challenge: once light leaves a photonic crystal it sprays out in all directions, and much of it is lost.’
- ‘The second trick is the use of photonic crystals, which prevent light of the desired wavelength from going sideways or getting ‘trapped.’’
- ‘Like the photonic crystals under development for visible light applications, the PBG structure appears translucent to some frequencies and reflective to others.’
- ‘Just as electrons in a silicon crystal cannot exist in the range of energies known as the band gap, light waves in a photonic crystal are forbidden from a specific range of wavelengths.’
