Threats to coral reefs are everywhere — rising water temperatures, ocean acidification, coral bleaching, fishing and other human activities. But new research shows that 3-D printed coral can provide a structural starter kit for reef organisms and can become part of the landscape as fish and coral build their homes around the artificial coral.
Read moreThe researchers used machine-vision automation and parallelization to simultaneously produce globally aligned, single-wall carbon nanotubes using pressure-driven filtration.
Read moreScientists are studying the fabrication of polymeric nanofibers and microfibers — very thin fibers made up of polymers. The fibers can be woven into textile-like structures but depending on the use, different fiber thicknesses may be necessary. To study the effects of various parameters on fiber fabrication, the researchers compared the characteristics of fibers created in different ways.
Read moreElectromagnetism was discovered 200 years ago, but the origin of the very large electromagnetic fields in the universe is still a mystery.
Read moreTiny magnetic vortices known as skyrmions form in certain magnetic materials, such as Cu2OSeO3. These skyrmions can be controlled by low-level electrical currents — which could facilitate more energy-efficient data processing. Now a team has succeeded in developing a new technique at the VEKMAG station of BESSY II for precisely measuring these vortices and observing their three different predicted characteristic oscillation modes (Eigen modes).
