Moire superstructures created using block copolymers

(Phys.org)—A team of researchers at the University of Alberta has developed a way to create moiré superstructures using block copolymers. In their paper published in the journal ACS Nano, the team describes the technique, ...

Nano-breakthrough: Solving the case of the herringbone crystal

Leading nanoscientists created beautiful, tiled patterns with flat nanocrystals, but they were left with a mystery: Why did some sets of crystals arrange themselves in an alternating, herringbone style? To find out, they ...

Robotic refueling mission begins with space station robotics

NASA's highly anticipated Robotic Refueling Mission (RRM) began operations on the International Space Station with the Canadian Dextre robot and RRM tools March 7-9, 2012, marking important milestones in satellite-servicing ...

Using light to build nanoparticles into superstructures

Scientists in the Center for Nanoscale Materials and Argonne's Biosciences Division have demonstrated a remarkably simple, elegant, and cost-effective way of assembling nanoparticles into larger structures of any desired ...

New math theories reveal the nature of numbers

For centuries, some of the greatest names in math have tried to make sense of partition numbers, the basis for adding and counting. Many mathematicians added major pieces to the puzzle, but all of them fell short of a full ...
