The world's smallest refrigerator

According to Nature, two theoretical physicists have used the Brownian motion to design a molecular-scale refrigerator powered by 'nano' paddles. And they think that this Brownian refrigerator will one day help cool nanoscale machines. Their mini fridge is composed of two pools of molecules separated by an insulating membrane. A...

Explaining science with drawings

A recent news release from the US National Science Foundation NSF mentions a project it helped to fund, 'Picturing to Learn.' For this project, college students have to create pencil drawings to explain scientific concepts to high school students. As says Felice Frankel, a Harvard University researcher who is leading...

Nanotubes looking for corkscrews

Many researchers around the world are looking at nanotubes as vehicles to deliver drugs to very precise locations such as individual cancerous cells. But these nanotubes need first to be closed in order to carry these drugs. And researchers at the University of Florida have found an elegant way to...

MacBrownian Cocoa 1.5 (Mac)

MacBrownianMotion is a small educational tool aimed at helping you understand one of the most widely used "noise" models--Brownian motion. Brownian motion is used to model anything from the movement of amoebas to stock market prices. Brownian motion is perhaps described as follows: stand at a point and flip a...

Degenerate Delay-Capacity Trade-Offs in Ad Hoc Networks With Brownian Mobility

There has been significant recent interest within the networking research community to characterize the impact of mobility on the capacity and delay in mobile ad hoc networks. In this paper, the fundamental trade-off between the capacity and delay for a mobile ad hoc network under the Brownian motion model is...
