Conventional air conditioners and refrigerators rely on vapor-compression cycles and chemical refrigerants that contribute significantly to global warming. Magnetic refrigeration offers a cleaner ...

Magnetic bead separation is a fast, effective, and clean process that scientists use as an alternative to filtration and centrifugation techniques for separation. Magnetic beads and particles can be ...

The National Academies of Sciences, Engineering, and Medicine have been asked to conduct a study on high-magnetic-field science and technology. The primary goal of the Committee on the Current Status ...

Magnetic nanoparticles exhibit a range of physical properties due to their small size and unique structure. Understanding and harnessing the physical properties of magnetic nanoparticles is essential ...

The types of magnetic sensors that are currently available. How the magnetic sensors work. Applications for the different magnetic sensors. Position sensors enable a variety of functions and controls ...

A flower-shaped structure only a few micrometres in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. The size of the effect can be controlled by varying the ...

Magnetic beads (or superparamagnetic particles) can be used for the isolation and purification of cells, nucleic acids, proteins or any other biomolecules. The surface of magnetic beads can be coated ...

The origins of magnetic steel can be traced back to the 18 th century when scientists began experimenting with iron alloys. In 1820, Hans Christian Oersted's accidental discovery of electromagnetism ...

Researchers use directed evolution to create magneto-sensitive fluorescent proteins that can interact with magnetic fields and radio waves ...
