Currently, organic materials used in these devices offer greater versatility and efficiency at a lower cost than the available inorganic ones, but they show stability problems when in contact with an aqueous medium. Researchers have now achieved an exceptional stability in these devices, which represents an important step in obtaining solar fuels from organic materials.
An international research group has developed a technique for creating nanoscale whispering galleries for electrons in graphene. The development opens the way to building devices that focus and amplify electrons just as lenses focus light and resonators (like the body of a guitar) amplify sound.
In what marks a significant step forward for artificial intelligence, researchers have demonstrated the functionality of a simple artificial neural circuit. For the first time, a circuit of about 100 artificial synapses was proved to perform a simple version of a typical human task: image classification.
By combining 3D holographic lithography and 2D photolithography, researchers have demonstrated a high-performance 3D microbattery suitable for large-scale on-chip integration with microelectronic devices.
A moth's eye and lotus leaf were the inspirations for an antireflective water-repelling, or superhydrophobic, glass coating that holds significant potential for solar panels, lenses, detectors, windows, weapons systems and many other products.
