New method found for controlling conductivity

A team of researchers at MIT has found a way to manipulate both the thermal conductivity and the electrical conductivity of materials simply by changing the external conditions, such as the surrounding temperature. And the ...

Caltech researchers design a new nanomesh material

(PhysOrg.com) -- Computers, light bulbs, and even people generate heat—energy that ends up being wasted. With a thermoelectric device, which converts heat to electricity and vice versa, you can harness that otherwise wasted ...

Graphene may hold key to speeding up DNA sequencing

September 9, 2010 - In a paper published as the cover story of the September 9, 2010 Nature, researchers from Harvard University and MIT have demonstrated that graphene, a surprisingly robust planar sheet of carbon just one-atom ...

Scientists transform polyethylene into a heat-conducting material

Most polymers -- materials made of long, chain-like molecules -- are very good insulators for both heat and electricity. But an MIT team has found a way to transform the most widely used polymer, polyethylene, into a material ...

Paper strips can quickly detect toxin in drinking water

(PhysOrg.com) -- A strip of paper infused with carbon nanotubes can quickly and inexpensively detect a toxin produced by algae in drinking water. Engineers at the University of Michigan led the development of the new biosensor.
