2010 FEI Image Contest Grand Prize Winners

On February 16, 2010, FEI invited owners and users of our instruments to submit their finest images for a chance to win two round-trip airline tickets to anywhere in the world. After six months and more than 250 images, FEI would like to congratulate Dr. Harald Plank of the Institute of Electron Microscopy, Austria, and Dr. Clifford Barnes of University of Ulster, United Kingdom for their prize-winning entries.
Grand Prize Winner – Technical Merit
Platinum Nanorods on Silicon
The image shows an array of freestanding Pt nanorods on silicon fabricated by electron beam induced deposition from the gas phase The individual rods reveal a base diameter of about 80 nm and a height of 1 µm. The wavy appearance was actually an artifact but too nice to be ignored. Image was post-colorized by Margit Wallner (FELMI).

Platinum Nanorods

Dr. Harald Plank

Institute of Electron Microscopy
Austria

Dr. Harald Plank "The FEI instrument we are mainly using is a NOVA 200 Dual Beam microscope which offers manifold possibilities and a high flexibility for additional custom made extensions. Similar experiments without such instrument would be partly impossible or require much higher efforts which make "Nanolab Workstations" an essential part of modern science and technology."

Grand Prize Winner – Most Popular Image
Spaghetti Junction
The sample was a piece of rat testes tissue which had been fixed in formalin before post fixation in osmium tetroxide. The image was captured in environmental scanning electron mode using the GSED detector. This allowed the imaging of the sample in a hydrated form without the need for dehydration and metallic coating. As less processing is involved it is expected that fewer artifacts are present and finer details preserved.

Dr. Clifford Barnes

University of Ulster
United Kingdom

Dr. Clifford Barnes "I have been primarily involved in the rapidly growing field of nanotoxicology over the past four years. I have found the FEI instruments we have in our FEI centre for Advanced Imaging including the Tecnai TEM, Quanta ESEM and cryo-DualBeam capable of providing unique information with the resolving power my work needs."
