The secret of unmagnetized magnets

EPFL physicists studying magnetic materials have discovered that they have some unexpected properties. Their research could lead to the development of even tinier magnets in the future.

Magnetic field sensor from Plastic paint developed by University of Utah

Physicists at University of Utah developed an inexpensive, highly accurate magnetic field sensor. This new magnetic field sensor, good for scientific or consumer uses is based on “spinotronic” organic thin film semiconductor which basically is a plastic paint resistent at heat and degradation. This plastic paint is only about 5 by 5 mm (one fifth […]

Power without the power cord

Cell phones and flashlights operate by battery without trouble. Yet because of the limited lifespan, battery power is not a feasible option for many applications in the fi elds of medicine or test engineering, such as implants or probes. Researchers have now developed a process that supplies these systems with power and without the power […]

All-electric highway that wirelessly charges cars and trucks

A Stanford University research team has designed a high-efficiency charging system that uses magnetic fields to wirelessly transmit large electric currents between metal coils placed several feet apart. The long-term goal of the research is to develop an all-electric highway that wirelessly charges cars and trucks as they cruise down the road.

Converting the energy of waste heat occurring in integrated circuits

The heat which occurs in tiny computer processors might soon be no longer useless or even a problem. On the contrary: It could be used to switch these processors more easily or to store data more efficiently!

Need for new magnet materials

Increasing demand and a shrinking supply of rare earth elements for magnets creates a perfect opportunity for a research team from Oak Ridge National Laboratory and the University of Minnesota. The goal is to create a recipe for a replacement that doesn’t use scarce ingredients.
