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 ...

Bristly Spheres as Capsules

(PhysOrg.com) -- Amphiphilic molecules, which have one water-friendly (hydrophilic) end and one water-repellant (hydrophobic) end, spontaneously aggregate in aqueous solutions to make superstructures like capsules or bilayers. ...

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 ...

Highlight: Quasi-Crystalline Order at Nanoscale

Nanoparticles have a strong tendency to form periodic structures. Mixing and matching of two different types of nanoparticles allows the formation of binary nanoparticle superlattices isostructural to ionic or intermetallic ...
