Hollow, nanoscale, scalene ellipsoids of Ag or Au provide an exceedingly tunable localized surface plasmon resonance. Here, we use numerical simulations to determine the limits of the color space that would be possible ...

The beta-phase of Au(7)Cu(5)Al(4) undergoes a reversible shape-memory phase transformation, however there has been some uncertainty regarding the crystal structure or structures of the parent phase. Here we show that, under ...
