We have achieved the enhanced thermoelectric response in polycrystalline Ca3Co4O9 on doping Tb ions in the material. Specifically, a high figure of merit (ZT) of 0.74 at 800 K was observed for Ca2.5Tb0.5Co4O9.
Both the absorption and emission of ultraviolet light by pyrene (PAH compound) are enhanced by more than 30-fold on nanostructured aluminum, compared to an equivalent control sample on sapphire (aluminum oxide).
We show the first demonstration of shape memory alloys being used for active THz devices. The metal foil was found to reproducibly cycle between the two geometries over 100 times.
Utah MRSEC establishes science and engineering afterschool clubs at community centers and schools serving predominately underrepresented minority (URM) students in those fields. The Education and Outreach team then hires and trains University of Utah undergraduates to lead the clubs and deliver hands-on activities each week.
Defects, essentially locations in a crystal where the perfect arrangement of atoms is disturbed, are inherent in materials, and play a key role in their function.
Transistors, the building blocks of all computer technologies, are currently based on semi-conductors such as silicon, manufactured using energy-intensive processes.
Cytoskeletal filaments with chemical motors attached are the basic elements in cells that enable biological motion. Computer simulation of model biomotive systems show that even systems with minimal ingredients are able to generate the kind of exotic nonequilibrium behavior observed in cells.
Researchers in the Soft Materials Research Center of the University of Colorado Boulder have employed dynamic covalent chemistry to make cross-links that can be controlled optically, enabling materials that can be softened or changed in shape by light.
Researchers at the University of Colorado Boulder have made a discovery that explores an inexpensive way to eliminate waste heat in buildings, cooling systems, and even cars and trucks.
