A Big Improvement in Thermoelectric Material
September 26, 2013 | 2 Comments
Scientists at the Vienna University of Technology (TU Vienna) can now produce a new and considerably more efficient class of thermoelectric material. The new molecular structure of the material has a very special layout in connection an astonishing new physical effect with tiny cages within the crystal structure enclosing cerium atoms. The Austrian team reports […]

A research team from the University of Michigan (UM) has found a way to nearly double the efficiency of a particular class of thermoelectric material. Thermoelectric materials can be used to turn waste heat into electricity or to provide refrigeration without any liquid coolants and the new class of them is made with organic semiconductors. […]

A New Cheap and Abundant Thermoelectric Material Found
November 29, 2012 | 2 Comments
A team of Michigan State University researchers have developed a new thermoelectric material based on natural minerals known as tetrahedrites, the most widespread sulfosalts on Earth. So where are these tetrahedrites? They’re found pretty much anywhere there is dirt, common ordinary dirt. The researchers, led by Donald Morelli, a professor of chemical engineering and materials […]

A Better Cheaper Thermoelectric Material
April 19, 2012 | 2 Comments
Purdue University assistant professor of chemical engineering Yue Wu leads a team developing a technique that uses nanotechnology to harvest energy from hot pipes or engine components. The team has coated glass fibers with a new thermoelectric material they developed. When thermoelectric materials are heated on one side electrons flow to the cooler side, generating […]
