1 Coolio Differential interference contrast image of polymer trilayer film with self- assembled in-plane morphology

2 Owl Collision of two holes caused by dewetting of a thin polymer film on a substrate

3 Polymer Juggler Surprised Dewetting of thin polymer film on a substrate

4 Two Stage Dewetting Two stage dewetting of polymer trilayer film on a substrate

5 Slimy 3D Confocal optical microscope projection of a mature bacterial biofilm

6 Rim Breakup Breakup of rim of growing hole in thin polymer film

7 Hole Growth Growth of hole in freely-standing polystyrene film

8 On the Edge Atomic force micrograph of pattern formation near the edge of a polymer wedge film

9 Criss-Cross Reformation of lateral patterns in freely- standing polymer trilayer film upon cooling of the film 95 o C 75 o C

10 Polymer Dots Self-assembly of dots containing 1 picogram ( g) of polymer in a freely-standing polymer trilayer film

11 Starry Night Final morphology of dewetted polymer film

12 Dewetting Dewetting of a polymer film on top of another polymer film

13 Polymer Hell Pattern formation observed at the edge of a spincoated polymer film

14 Beautiful Bands In-plane banded structure which self- assembles in a heated polymer trilayer film

15 Volcano Atomic force micrograph of dewetting of top layer of polymer trilayer film

16 Criss-Cross In-plane banded structure which self- assembles in a heated polymer trilayer film and then reforms with a larger period upon cooling

17 The Scream Pattern formation observed near the edge of a spincoated polymer film

18 Velvet Differential interference contrast image of a freely- standing polymer film which wrinkles upon heating

19 Knitting Balls Atomic force microscopy image of a self-assembled array of polymer microspheres
