Multiferroics could lead to low-power devices

(PhysOrg.com) -- Magnetic materials in which the north and south poles can be reversed with an electric field may be ideal candidates for low-power electronic devices, such as those used for ultra-high data storage. But finding ...

Creating atomic scale nanoribbons

Silicon crystals are the semiconductors most commonly used to make transistors, which are critical electronic components used to carry out logic operations in computing. However, as faster and more powerful processors are ...

Simulations show how atoms behave inside self-healing cement

Researchers at Pacific Northwest National Laboratory (PNNL) have developed a self-healing cement that could repair itself in as little as a few hours. Wellbore cement for geothermal applications has a life-span of only 30 ...

Magnetic materials: Forging ahead with a back-to-basics approach

Scientists have recently started to explore the possibility of using an intrinsic property of the electron known as spin for processing and storing information. Magnetic fields can influence the dynamics of electron spin, ...

Team maps the nuclear landscape

An Oak Ridge National Laboratory and University of Tennessee team has used the Department of Energy's Jaguar supercomputer to calculate the number of isotopes allowed by the laws of physics.

Keeping hydrogen from cracking metals

Metal alloys such as steel and zirconium that are used in pipes for nuclear reactors and oil fields naturally acquire a protective oxide or sulfide layer. But hydrogen penetration can lead to their breakdown and speed up ...
