One of the common modes of scanning probe microscopy (SPM) is Magnetic force microscopy (MFM). As indicated by the name, SPM is used to map magnetic properties. On the nanoscale, MFM probes local ...

Magnetic force microscopy (MFM) is one of the modes of scanning probe microscopy (SPM). As the name implies, it is used to map magnetic characteristics. MFM investigates the local magnetic fields at ...

Traditional magnetic separators, however, present a challenge: they generate a magnetic force that is very high near the side of the vessel closest to the magnet and decreases rapidly with distance.

China achieves a superconducting magnet of 35.6 teslas, 700,000 times stronger than Earth's magnetic field, setting a world record.

In nanotechnology and molecular biology, researchers are often severely limited by the inability to observe atoms and molecules in three dimensions. Proteins, for instance, fold into complex patterns ...

Magnetic separation has become increasingly popular in biomedical science and industry. This technology uses magnetic properties of micro/nano-sized particles to separate macromolecules of interest, ...

Military leaders have been warning of the fragility of GPS for years and researchers have been working on a variety of solutions, from quantum clocks to inertial navigation. The Air Force is adding a ...

Voyager 2, NASA's legendary interstellar probe, continues to deliver. Thirty-one years after the spacecraft cruised past Uranus, researchers have capitalized on the spacecraft's recordings to take a ...
