Microscopes don't exactly lie, but their limitations affect the truths they can tell. For example, scanning electron microscopes (SEMs) simply can't see materials that don't conduct electricity very well, and their high energies ...
(Phys.org) —Researchers from North Carolina State University have found a way to reduce the coercivity of nickel ferrite (NFO) thin films by as much as 80 percent by patterning the surface of the material, opening the door ...
M. S. M. Saifullah and Hemant Raut of A*STAR's Institute of Materials Research and Engineering in Singapore and their co-workers have developed a coating that matches the optical properties of the best conventional anti-reflective ...
Artificial materials containing arrays of metal nanostructures can interact with light in useful and interesting ways. One of the most interesting possible uses of such 'metamaterials' is to bend light around objects, rendering ...
Researchers at the MIRA research institute have succeeded in imprinting microscopically small shapes on the surfaces of miniscule fibres. They were able to create all kinds of patterns on the surfaces of fibres just six micrometres ...
(Phys.org)—A team of researchers from South Korea have developed bendable polymer electrolytes for lithium ion batteries. The Yonhap News Agency carried the announcement, which has led to numerous suggestions, along with ...
Fast, high-volume production of plastics with specially engineered surfaces will soon be available using a cheaper and simpler method. IMRE and its Industrial Consortium On Nanoimprint (ICON) partner companies are piloting ...
(Phys.org) -- Titanium dioxide, or titania, is an inorganic material commonly used as a whitening agent in food and toothpaste. It is also used as one of the main active ingredients in sunscreens. The properties that make ...
Advances in microchip technology may someday enable clinicians to perform tests for hundreds of diseases -- sifting out specific molecules, such as early stage cancer cells -- from just one drop of blood. But fabricating ...
(PhysOrg.com) -- In an effort to increase the recording densities of hard disk drives, patterned media has become one of the most promising strategies for achieving recording densities beyond 1 Tbit/in2. In patterned media, ...
