 | In finally answering an elusive scientific question, researchers with the US Department of Energy's Lawrence Berkeley National Laboratory have shown that the selective placement of strain can alter the electronic phase and its spatial arrangement in correlated electron materials. This unique class of materials is commanding much attention now because they can display properties such as colossal magnetoresistance and high-temperature superconductivity, which are highly coveted by the high-tech industry. ...> Full Article |
 | A multidisciplinary team of investigators from Case Western Reserve University, Duke University and University of Massachusetts, Amherst, created an environment where magnetic particles suspended within a specialized liquid solution acted like molecular sheep dogs by nudging free-floating human cells to form chains in response to external magnetic fields. ...> Full Article |
 | A technique of capturing the magnetic "fingerprints" of magnetic nanostructures -- even when they are buried within the boards and junctions of an electronic device -- has been developed by a team of researchers at University of California, Davis. The technique should serve as a valuable tool in the development of next-generation storage and recording media by contributing to the understanding of how to encode information with nanomagnetic arrays. ...> Full Article |

 | Physicists have found that applying an electrical field on a surface-supported gold nanocluster changes its structure from a three-dimensional one to a planar flat structure. In another paper, they relate their discovery that gold in this size regime can be made magnetic through oxygenation of gold nanowires. They also found that up to a certain length, oxygenated gold nanowires behave as a conducting metal, but beyond that, they become insulators. This marks the first time on the nanoscale that such a metal-to-insulation transition has been found on the nanoscale. Both findings are important predictions that could some day be implemented as control parameters governing the chemical and physical material properties employed in nanotechnology. ...> Full Article |

 | X-rays have been used for decades to take pictures of broken bones, but scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory and their collaborators have developed a lensless X-ray technique that can take images of ultra-small structures buried in nanoparticles and nanomaterials, and features within whole biological cells such as cellular nuclei. ...> Full Article |

 | Scientists have devised remotely controlled nanoparticles that, when pulsed with an electromagnetic field, release drugs to attack tumors. The innovation, reported in the Nov. 15 online issue of Advanced Materials, could lead to the improved diagnosis and targeted treatment of cancer. ...> Full Article |
 | A researcher and his colleagues have found a novel way to "look" at atomic orbitals, and have directly shown for the first time that they change substantially when interacting at the interface of a ferromagnet and a high-temperature superconductor. ...> Full Article |
New research led by the U.S. Department of Energy's Argonne National Laboratory physicist Matthias Bode provides a more thorough understanding of new mechanisms, which makes it possible to switch a magnetic nanoparticle without any magnetic field and may enable computers to more accurately write and store information.
