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 […]

North Carolina State University scientists are researching birnessite. Birnessite is a hydrated layered form of manganese oxide that can quickly store and release a variety of positive ions from electrolytes for many cycles. This makes it promising for use in high-power electrochemical energy storage, or in emerging electrochemical technologies such as desalination and rare element […]

Open Image…Save ImageOpen Image (using #TmpD/ia)… SLAC National Accelerator Laboratory scientists took a unique and detailed nanoscale look at how oxygen seeps out of lithium-ion battery electrodes, sapping their energy over time. Measuring the process in unprecedented detail gave them clues to how to minimize the problem and protect battery performance. The results could suggest a fix. When lithium ions […]

Open Image…Save ImageOpen Image (using #TmpD/ia)… Rice University engineers have created microscopic seeds for growing remarkably uniform 2D perovskite crystals that are both stable and highly efficient at harvesting electricity from sunlight. Halide perovskites are organic materials made from abundant, inexpensive ingredients, and Rice’s seeded growth method addresses both performance and production issues that have held back halide perovskite photovoltaic […]

A University of Tsukuba researcher has introduced a new theory for superconductivity that can better explain the results of recent experiments with high-temperature superconductors. By focusing on the ‘Berry connection,’ this work may lead to energy distribution with much less electrical resistance. The scientist works at the Division of Quantum Condensed Matter Physics at the […]
