I'm looking for the title of a story in which a girl, an immigrant from Eastern Europe or the Middle East, figures out the formula for a room-temperature superconductor and keeps it secret-in-the-open because she is powerless. Her family manufactures a lot of it, all stamped with the family name and innocuous, integrated into power cables so that many people will see it and her fame can't be stolen.
IIRC, this story was published around 2010.
EDIT : This may have been included in Gardner Dozois' "Year's Best Science Fiction", which I will now review the list of titles. I'm not certain I'll recognize the title. The story may have been set in Turkey.
