- Chip-based system for terahertz waves could enable more efficient, sensitive electronicsResearchers developed a low-cost, scalable terahertz amplifier that could be used to make antenna arrays that can steer and focus high-frequency terahertz waves, for applications like high-resolution radar, high-speed communications, and medical imaging.
- Cooling materials -- Out of the 3D printerRapid, localized heat management is essential for electronic devices and could have applications ranging from wearable materials to burn treatment. While so-called thermoelectric materials convert temperature differences to electrical voltage and vice versa, their efficiency is often limited, and their production is costly and wasteful. Researchers have now used a 3D printing technique to fabricate […]
- A miniature swimming robot inspired by marine flatwormsEngineers have developed a versatile swimming robot that nimbly navigates cluttered water surfaces. Inspired by marine flatworms, the innovative device offers new possibilities for environmental monitoring and ecological research.
- Towards new battery tech: Chemists demonstrate high-performance sodium-ion cathodeFor decades, scientists have sought ways to counter our dependence on lithium-ion batteries. These traditional, rechargeable batteries energize today's most ubiquitous consumer electronics -- from laptops to cell phones to electric cars. But raw lithium is expensive and is often sourced through fragile geopolitical networks. This month, chemists have announced an exciting alternative that relies […]
- For success in bioelectronics, build with nature-inspired designResearchers have 3D printed bioelectronic scaffolds that have the properties cells need to form new tissue.
- Magnetic switch traps quantum information carriers in one dimensionA quantum 'miracle material' could support magnetic switching, a team of researchers has shown.
