1st Place Winner Gold Nanopyramids
High resolution scanning electron micrograph (SEM) of gold nanopyramids supported by silicon pedestals. The orientation-dependent optical properties of the nanoparticle arrays have revealed new insight into the interaction between light and materials at the nanoscale. These structures are also being explored in applications such as chemical and biological sensing and nanophotonics. Joel Henzie developed the large-area (>1 in. 2 covered by ~10 8 pyramids) nanofabrication techniques to create the pyramids while working in the Odom lab at Northwestern University . The results are published in J. Phys. Chem. B [Joel Henzie, Kevin L. Shuford, Eun-Soo Kwak, George C. Schatz, and Teri W. Odom, J. Phys. Chem. B ., 2006, 110 , 14028-14031].

1st Place Winner “Ancient of Days” from classical art to quantum art
A 500×500 µm photoluminescence image of “Ancient of Days” was created in porous silicon using focused helium beam writing and subsequent electrochemical etching in hydrofluoric acid. Due to quantum confinement effect, visible light emission is observed from the nanosized silicon skeleton left behind after etching. It is found that pre-irradiation with a helium beam is able to change the local resistivity of the silicon and the emission wavelength of the porous silicon formed. The higher the dose of the beam, the redder the photoluminescence wavelength becomes. Here, we see that the figure of the man is depicted in orange and his face and masculinity is highlighted by the black outline created using high dose irradiation. His left hand reaches out for a pair of compass that is rested on a red sphere, surrounded with a yellowish orange aura. Using the high resolution capability of focused ion beam writing, we are able to transform William Blake’s piece of classical art into an image consisting of finely tuned nanocrystals, which we call ‘quantum art’.

2nd Place Winner Nano-pop
This picture is showing side-view of a silicon-nanowire held between and resting on two opposite nickel electrodes. One end (right side) of the nanowire has small nickel sphere on it which makes it look like a lollipop and since here it is with nanowire we gave it a name “Nano-pop”. This picture was captured using Hitachi S-4700 FESEM while the normal to the sample was making 85 degrees angle with respect to primary electron beam of the FESEM.

2nd Place Winner
Pollen Dawn
This SEM image was taken from surface of a TiO2 pollen. The pollen was converted into titania chemistry by using shape-preserving gas-solid displacement reaction. The apparent grainy surface was nanocrystalline anatase. The original image was manipulated in an image editing program to add color and lighting effects.

2nd Place Winner
Water on a Nanostructured Gold Surface
The image is a photograph of a droplet of water sitting on a nanostructured gold surface prepared by templated electrodeposition. The colours are produced by the reflection of white light and excitation of surface plasmons on the structured surface. Surfaces of this type show strong surface enhancement for SERS of molecules adsorbed at their surface.
