Northwestern University scientists have demonstrated a high-performing thermoelectric material in a practical form that can be used in device development. The material – purified tin selenide in polycrystalline form – outperforms the single-crystal form in converting heat to electricity, making it the most efficient thermoelectric system on record. A key application target of thermoelectric devices […]

Stanford University researchers led by Professor Roger Howe say new material using graphene could reignite the field of thermionic energy conversion, improving the way we produce electricity and reducing the impact the process has on the environment. The concept is based on a satellite-powering technology that was abandoned decades ago that has been reinvented to […]
