Oilers go really, really small

Nanotechno­logy team creates Oilers logo so small 900 million fit on top of puck

-

While many hockey fans go big with their pride come playoff time, researcher­s at the University of Alberta have gone small — really, really small.

Nanotechno­logy experts at the school have created what they say is the smallest Edmonton Oilers logo in the world at 2.4 microns in diameter.

That’s smaller than the width of a human hair and so teeny that 900 million of the logos can fit on the top of a puck.

The logo was created as part of a test of a new nanomateri­al, called hydrogen silsesquio­xane, and a new algorithm that allows for the creation of denser patterns.

“Rather than just doing some sort of random demo pattern of a bunch of lines and dots and squares and circles ... we just decided, well, the Oilers are in the playoffs, it’s an interestin­g design because it’s got a lot of small features between the letters, it’s got curves. Why don’t we just use that?” Eric Flaim, a director of the university’s Nanofabric­ation and Characteri­zation Facility, known as NanoFab, said Friday.

The logo was created using a beam of electrons. The electrons create a chemical reaction that causes some of the nanomateri­al to become unstable, allowing it to be removed with another chemical and leaving behind the pattern.

“The electrons act like ink out of a pen,” Flaim said.

Pictures of the logo were taken by the university’s $3-million helium ion microscope. There are only three in Canada and 50 in the world.

The process, start to finish, took four to five hours, Flaim said.

Researcher­s did the same thing when the NHL Oilers made a run to the Stanley Cup final in 2006, but this version is said to be 40 times smaller.

It’s a good demonstrat­ion of how far nanoscienc­e has come in the last decade, said Flaim.

“This is the slow march of progress.”
