Particle-Based Inverted Crystal

Caption

The researchers created an ordered array of both 100 and 10 micro-meter particles. After chemically etching away the 100 micro-meter particles, what remains is a highly ordered porous material with both large and small pores whose sizes are completely tunable (via choice of initial particles). From left to right the panels show progressively wider frames.
