‘Living’ electrodes breathe new life into traditional silicon electronics
Feb 05, 2025 (Nanowerk News) High-speed electronic devices that do not use much power are useful for wireless communication. High-speed operation has traditionally been achieved by making devices smaller, but as devices become smaller, fabrication becomes increasingly difficult. Have we reached a dead end? Not yet! A research team at...
Physicists measure a key aspect of superconductivity in magic-angle graphene
Feb 05, 2025 (Nanowerk News) Superconducting materials are similar to the carpool lane in a congested interstate. Like commuters who ride together, electrons that pair up can bypass the regular traffic, moving through the material with zero friction. But just as with carpools, how easily electron pairs can flow depends...
Researchers discover new way to customize living materials for tissue engineering, drug delivery and 3D printing
Feb 05, 2025 (Nanowerk News) Rice University researchers have revealed novel sequence-structure-property relationships for customizing engineered living materials (ELMs), enabling more precise control over their structure and how they respond to deformation forces like stretching or compression. The study, published in a special issue of ACS Synthetic Biology ("Genetically Modifying...
Vitamin crystals generate electricity from movement, enabling self-powered medical devices
Feb 05, 2025 (Nanowerk Spotlight) Medical devices that interface with the human body need power sources as safe as they are reliable. While sophisticated electronics can monitor health conditions and deliver treatments, powering these devices without risking tissue damage or immune responses remains a fundamental challenge. Materials that generate electricity...
How dangerous are nanoplastics for babies in the womb?
Feb 05, 2025 (Nanowerk News) Asthma, hay fever or chronic skin conditions: The occurrence of allergic reactions is diverse and on the rise. Among other things, environmental factors during the child's early development in the womb are suspected, which lay the foundation for later illnesses. A team of researchers from...
Quasi-1D dynamics in molecular spin systems
Feb 05, 2025 (Nanowerk News) Quantum spin liquids (QSLs) are fascinating and mysterious states of matter that have intrigued scientists for decades. First proposed by Nobel laureate Philip Anderson in the 1970s, these materials break the conventional rules of magnetism by never settling into a stable magnetic state, even at...
Nanotechnology for oil spill response and cleanup in coastal regions
Feb 04, 2025 (Nanowerk News) Cleaning up after a major oil spill is a long, expensive process, and the damage to a coastal region’s ecosystem can be significant. This is especially true for the world’s Arctic region, where newly opened sea lanes will expose remote shorelines to increased risks due...
Nanodevice generates electricity and light simultaneously using only movement
Feb 04, 2025 (Nanowerk News) DGIST announced that research teams led by Prof. Kim Hoe Joon (Department of Robotics and Mechatronics), Dr. Jeong Soon Moon (Division of Energy and Environmental Technology), and Prof. Mishra (University of Southern Denmark) conducted international joint research and developed a self-powered sensor that uses motion...
Mott-based hybrid material switches conductivity while preserving ferroelectric control
Feb 04, 2025 (Nanowerk Spotlight) Electronic devices work through precise control over the flow of electricity. While typical materials act as either conductors or insulators, the ability to switch between these states within a single material could transform how we build and control electronic components. This capability becomes even more...
