Electricity from waste heat with more efficient materials

Thermoelectric materials can convert waste heat directly into electricity. Tommi Tynell, M.Sc., who is a doctoral candidate at the Aalto University School of Chemical Technology, has developed hybrid thermoelectric materials ...

Spinning atoms in light crystals

(Phys.org) —After more than 40 years of intense research, experimental physicists still seek to explore the rich behaviour of electrons confined to a two-dimensional crystalline structure exposed to large magnetic fields. ...

Creating electricity with caged atoms

Clathrates are crystals consisting of tiny cages in which single atoms can be enclosed. These atoms significantly alter the material properties of the crystal. By trapping cerium atoms in a clathrate, scientists at the Vienna ...

Scientists use DNA to assemble a transistor from graphene

(Phys.org) —Graphene is a sheet of carbon atoms arrayed in a honeycomb pattern, just a single atom thick. It could be a better semiconductor than silicon – if we could fashion it into ribbons 20 to 50 atoms wide. Could ...

Two become one with the 3-D NanoChemiscope

The 3D NanoChemiscope is a miracle of state-of-the-art analysis technology. As a further development of well-known microscopic and mass spectroscopic methods, it maps the physical and chemical surfaces of materials down to ...

A new form of carbon: Grossly warped 'nanographene'

Chemists at Boston College and Nagoya University in Japan have synthesized the first example of a new form of carbon, the team reports in the most recent online edition of the journal Nature Chemistry.

Graphene on its way to conquer Silicon Valley

The remarkable material graphene promises a wide range of applications in future electronics that could complement or replace traditional silicon technology. Researchers of the Electronic Properties of Materials Group at ...
