High-Performing Thermoelectric Material May Improve Clean Energy Research
Researchers at the University of Houston have discovered a new thermoelectric material capable of high performance at temperatures ranging from room temperature to 300 degrees Celsius (573 degrees Fahrenheit) and possibly higher. The material is reportedly the first new high-efficiency thermoelectric material in 60 years, and could be important for both clean energy research … [Read more...]
New Research Shows Unlimited Heat Conduction Potential in Graphene
An international team of scientists has found the thermal conductivity of graphene changes depending on the size of the material sample, a discovery they say challenges the fundamental laws of heat conduction for extended materials. Davide Donadio, head of a research group at the Max Planck Institute for Polymer Research (MPI-P) in Germany and his colleagues from the National … [Read more...]
Solving the Thermoelectric Mystery
Thermoelectric materials—substances that exhibit the so-called thermoelectric effect, in which a temperature difference creates an electric potential or vice versa—have been known for decades and employed in applications including power generation and refrigeration. Despite their commercial use, however, scientists have remained somewhat baffled as to why some of these … [Read more...]
Waste Sulfur May Improve Thermal Imaging Lenses
The discovery of a new use for waste material left over refining fossil fuels could lead to benefits for the thermal imaging industry. A University of Arizona-led international team has found that the sulfur left over from the refining process can be transformed into inexpensive, lightweight plastic lenses for infrared detection devices. "We have for the first time a polymer … [Read more...]
