Creating Denser Magnetic Memory

(PhysOrg.com) -- One of the issues afflicting magnetic memory is the fact that it is difficult to store information for as long as 10 years. In order to overcome this problem, scientists and engineers have been looking for ...

Shape matters in the case of cobalt nanoparticles

Shape is turning out to be a particularly important feature of some commercially important nanoparticles—but in subtle ways. New studies* by scientists at the National Institute for Standards and Technology (NIST) show ...

Cobalt Nanoparticles Boost Imaging Sensitivity and Edge Detection

(PhysOrg.com) -- Magnetic resonance imaging (MRI) can serve as a very sensitive technique for detecting small tumors in the body, but it is not as good at identifying the edges of a tumor. Photoacoustic imaging tomography ...

Turning sunlight into liquid fuels (Video)

(PhysOrg.com) -- For millions of years, green plants have employed photosynthesis to capture energy from sunlight and convert it into electrochemical energy. A goal of scientists has been to develop an artificial version ...

Nano-sonar uses electrons to measure under the surface

Just as sonar sends out sound waves to explore the hidden depths of the ocean, electrons can be used by scanning tunnelling microscopes to investigate the well-hidden properties of the atomic lattice of metals. As researchers ...
