Rare-earths become water-repellent only as they age

Surfaces that have been coated with rare earth oxides develop water-repelling properties only after contact with air. Even at room temperature, chemical reactions begin with hydrocarbons in the air. In the journal Scientific ...

Researchers develop a simple but extremely sensitive magnetometer

VTT Technical Research Centre of Finland has developed an innovative magnetometer that can replace conventional technology in applications such as neuroimaging, mineral exploration and molecular diagnostics. Its manufacturing ...

Speed limit set for ultrafast electrical switch

Researchers from the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have clocked the fastest-possible electrical switching in magnetite, a naturally magnetic mineral. Their results could drive innovations ...

Magnetic rocks aid oil exploration

A new study has pinpointed the relationship between oil reservoirs and magnetic rocks, which could lead to more accurate oil exploration.

Missing data on Earth's magnetic field is in the oven

(Phys.org)—A New Zealand research team hopes to retrieve missing parts of a puzzle about the Earth's magnetic field and changes to it over time. Grabbing their attention are the stones that line Maori steam ovens. They ...
