• One glass, full color: Sub-millimeter waveguide shrinks AR glasses
  Augmented-reality (AR) technology is rapidly finding its way into everyday life, from education and healthcare to gaming and entertainment. However, the core AR device remains bulky and heavy, making prolonged wear uncomfortable. A breakthrough now promises to change that. A research team has slashed both thickness and weight using a single-layer waveguide.
• Eco-friendly aquatic robot is made from fish food
  An edible robot leverages a combination of biodegradable fuel and surface tension to zip around the water's surface, creating a safe -- and nutritious -- alternative to environmental monitoring devices made from artificial polymers and electronics.
• Vapor-deposited perovskite semiconductors power next generation circuits
  A research team has developed a groundbreaking technology poised to revolutionize next-generation displays and electronic devices.
• Engineers advance toward a fault-tolerant quantum computer
  Researchers demonstrated extremely strong nonlinear light-matter coupling in a quantum circuit. Stronger coupling enables faster quantum readout and operations, ultimately improving the accuracy of quantum operations.
• Rapid lithium extraction eliminates use of acid and high heat, scientists report
  Lightweight lithium metal is a heavy-hitting critical mineral, serving as the key ingredient in the rechargeable batteries that power phones, laptops, electric vehicles and more. As ubiquitous as lithium is in modern technology, extracting the metal is complex and expensive. A new method enables high-efficiency lithium extraction -- in minutes, not hours -- using low […]
• A new recycling process for silicones could greatly reduce the sector's environmental impacts
  A study describes a new method of recycling silicone waste (caulk, sealants, gels, adhesives, cosmetics, etc.). It has the potential to significantly reduce the sector's environmental impacts. This is the first universal recycling process that brings any type of used silicone material back to an earlier state in its life cycle where each molecule has […]
