Achromatic metasurface waveguide technology is revolutionizing augmented reality (AR) displays by addressing the longstanding issue of chromatic aberration. Developed by a research team from China, this innovative approach combines inverse-designed metasurface couplers with a high refractive index waveguide, achieving superior color accuracy and uniformity across a wide field of view. The technology promises to enhance the visual experience in compact AR systems, paving the way for advanced applications in various fields by overcoming the limitations of traditional diffractive waveguides.
Fungi are considered a promising source of biodegradable materials. Empa researchers have developed a new material based on a fungal mycelium and its own extracellular matrix. This gives the biomaterial particularly advantageous properties.
A new technique enables the use of, for example, cooking oil from fast-food restaurants to dissolve and separate silver. The process requires light and diluted hydrogen peroxide. The technique makes it possible to secure the supply of silver and reduce the burden on the environment.
