This year again Materials Today cover competition has been a resounding success, with over 100 participants and more than 125 pictures submitted!
Selecting only 13 of them was a real challenge.
As we will have two double issues in 2009, the 10 winning pictures will appear on the cover of Materials Today through the year, while all 13 will be featured in our 2009 calendar. Each finalist will receive two complimentary copies of the calendar.
