By using atom probe tomography, researchers have provided an atomic-level view of the composition of a nanowire, allowing for precise measurement of dopant atoms and understanding of synthesis conditions. This breakthrough enables control over electronic properties of nanowire devices, paving the way for improved device performance.
Researchers have developed a new proton exchange membrane (PEM) material that retains conductivity even at low humidity, overcoming a significant challenge for fuel cells. This breakthrough, achieved through self-assembling block copolymer materials, has the potential to increase the efficiency and feasibility of hydrogen-based energy ...
Researchers are developing a new combinatorial toolkit to evaluate hundreds of potential PEM fuel cell materials in a single experiment. The goal is to double membrane durability and cut costs in half. This project involves creating low-cost, thermally stable membranes using a 'formulation approach' that combines different polymers.
Scientists have made a breakthrough in molecular electronics by controlling the conductivity of molecules on a single atom. This innovation allows for the creation of ultra-small and efficient devices, requiring less energy to power and producing less heat than conventional transistors.
Researchers found that molecules' apparent on-off conductivity was due to a weak bond with the gold surface, breaking contact and turning electrical connection off. The team confirmed this finding through experiments at varying temperatures, ruling out other explanations.
Researchers at Washington University in St. Louis have successfully made boron nanowhiskers, the world's first crystalline nanowires, exhibiting semiconducting behavior and potential as key materials in nanoelectronics. The discovery could lead to the development of more reliable conductors, solving limitations faced by carbon nanotubes.
