University of Pennsylvania Researchers Demonstrate a Flexible, One-Step Assembly of Nanoscale Structures
(29 Jul 2008)
Scientists at the University of Pennsylvania have created a one-step, repeatable method for the production of functional nanoscale patterns or motifs with adjustable features, size and shape using a single master "plate."Researchers took advantage ...

Surface dislocation nucleation: Strength is but skin deep at the nanoscale, Penn engineers discover
(05 Mar 2008)
For centuries, engineers have bent and torn metals to test their strength and ductility. Now, materials scientists at the University of Pennsylvania School of Engineering and Applied Science are studying the same metals but at nanoscale sizes in the ...

Penn Engineers Create Carbon Nanopipettes That Are Smaller Than Cells and Measure Electric Current
(17 Jan 2008)
University of Pennsylvania engineers and physicians have developed a carbon nanopipette thousands of times thinner than a human hair that measures electric current and delivers fluids into cells. Researchers developed this tiny carbon-based tool to ...

Sand, Other Granular Matter's Behavior Is Better Defined
(07 May 2007)
Penn Physicists Develop Force Law for Granular Impacts
A single grain of sand is tiny, but solid, and shares the physical properties of other solid matter. But pack or transport millions of grains together - as modern society does with coffee grounds, flour and industrial chemicals - and granular ...

Magnetic field points the way for metallic nanorods with hydrogen peroxide propulsion
(07 Jan 2005)
Remote Control Nanomotor
Like their normally sized analogues, nanoscale machines and robots need motors to function. Some time ago, a team at Pennsylvania State University developed a clever engine to "drive" nanoscopic metal rods; however, until now, these tiny ...
