Sep 03, 2022 (Nanowerk News) Thermoelectric devices convert thermal energy into electricity by generating a voltage from the difference in temperature between the hot and cold parts of a device. To better understand how the conversion process occurs at the atomic scale, researchers used neutrons to study single crystals of...
Motion of DNA linked to its damage response, ability to repair itself
Sep 03, 2022 (Nanowerk News) A multidisciplinary team of Indiana University researchers have discovered that the motion of chromatin, the material that DNA is made of, can help facilitate effective repair of DNA damage in the human nucleus -- a finding that could lead to improved cancer diagnosis and treatment....
Multilayer stack opens door to low-power electronics
Sep 03, 2022 (Nanowerk News) Researchers found that a stack of ultrathin materials, characterized in part at the Advanced Light Source (ALS), exhibits a phenomenon called negative capacitance, which reduces the voltage required for transistor operation (Nature, "Ultrathin ferroic HfO2-ZrO2 superlattice gate stack for advanced transistors"). The material is fully...
