Within tiny halos of light clinging to a vanishingly thin wisp of optical fiber, scientist Jongmin Lee guides atoms like marbles through a narrow pipe. Rock the fiber and the atoms shift side by side; they just don't fall off.

Polyether ether ketone (PEEK) composites face concurrent ultraviolet (UV) and thermo-oxidative aging in real-world service environments, yet the synergistic effects remain poorly understood.

As the global energy demand continues to grow — driven in part by the rise of artificial intelligence — researchers are exploring technologies that can provide affordable, reliable, and safe sources of electricity.

Lithium metal anodes offer a theoretical energy density nearly double that of conventional graphite anodes - 454 Wh kg-1 compared to 314 Wh kg-1 at the cell level when paired with lithium nickel cobalt aluminum oxide cathode.

Electrochemical research often requires more than current, potential and time data alone. While a potentiostat provides essential control and measurement of the electrochemical experiment, it does not directly identify the gases or volatile species being produced during a reaction.

As transistors approach atomic dimensions, the interface between different materials grows in importance. Researchers from?National Yang Ming Chiao Tung University (NYCU), TSMC Corporate Research, and colleagues from National Taiwan University, Academia Sinica, and the National Center for Instrumentation Research have devised an interface engineering approach to address a major challenge in two-d…

Because many natural and industrial processes rely on the transport of bubbles and droplets through fluids, the behavior of ordinary air bubbles and water droplets has been well documented.

Researchers at the Department of Energy's (DOE) Oak Ridge National Laboratory (ORNL) have developed an artificial intelligence framework that helps researchers use atomic force microscopes to identify important nanoscale features while autonomously targeting the most informative areas of a sample for closer study.

The advanced manufacturing technologies have driven mechanical equipment toward higher speeds, greater loads, and longer service lifetimes. The intensive and high-frequency operation inevitably leads to friction and wear of mechanical components, compromising their reliability, functionality, and service life, as well as leading to safety issues and causing considerable waste of energy and resour…

A research team at the University of Vienna led by physicist Jani Kotakoski demonstrates how the shape of nanopores in hexagonal boron nitride - the electrically insulating counterpart to graphene, also known as "white graphene" - can be precisely controlled at the atomic level. Electron irradiation in ultra-high vacuum creates circular pores, while adding small amounts of oxygen yields triangula…

Virginia Tech researchers have put that idea to the test, creating degradable polymers with a new molecular architecture that combines properties that are often difficult to achieve in one material: strength, toughness, flexibility, and the ability to block oxygen.

Until now, it has been almost impossible to measure the energy density of hydrogen precisely, but a new sensor can register every single molecule. This could lay the foundation for correct accounting in the hydrogen economy.

High-entropy alloys are highly promising structural and functional materials. Among them, refractory high-entropy alloys possess outstanding high-temperature mechanical properties and have broad application prospects in critical components under extreme working conditions such as aerospace, nuclear power, and gas turbines.

A signal that appears to show ions moving inside a battery may, in fact, be an illusion caused by an uneven surface. A KAIST research team has identified the origin of this type of artifacts, which can lead researchers to misinterpret what is happening inside a battery, and has developed a method to reduce it. The findings are expected to enable more accurate analysis of ion movement and improve …
