Researchers have discovered a new way to simultaneously image both the ferromagnetic and the ferroelectric domain structures of multilayer devices in which a ferromagnetic film is grown on a ferroelectric substrate. These structures have attracted significant recent interest due to their ability to efficiently use voltage to change the magnetization in low-energy magnetic devices.
Nanostructures of virtually any possible shape can now be made using a combination of techniques. Especially the unique properties of so-called perovskites can be exploited further: their crystal structure is not influenced by the process.
Researchers have piloted a novel purification process to dramatically cut the cost of extracting specific biological molecules from complex mixtures - a boost to the competitiveness of Europe's pharmaceutical, food and animal feed industries.
Engineers have constructed the world's first electrical motor applying a textile material; carbon nanotube yarn. The presently most electrically conductive carbon nanotube yarn replaces usual copper wires in the windings.
Lithium ions traveling through a zinc antimonide anode cause local stress and phase transitions, a process dubbed atomic shuffling. These changes may help explain why most anodes made of layered materials eventually fail.
Cancer vaccines have recently emerged as a promising approach for killing tumor cells before they spread. But so far, most clinical candidates haven't worked that well. Now, scientists have developed a new way to deliver vaccines that successfully stifled tumor growth when tested in laboratory mice. And the key is in the vaccine's unique stealthy nanoparticles.
Using mesocosms that closely approximate wetland ecosystems, researchers show carbon nanotubes accumulate quickly in sediments - a tendency that could indirectly damage aquatic food chains by piggybacking harmful molecules.
Thermal considerations are rapidly becoming one of the most serious design constraints in microelectronics, especially on submicron scale lengths. A new study has shown that standard thermal models will lead to the wrong answer in a three-dimensional heat-transfer problem if the dimensions of the heating element are on the order of one micron or smaller.
Having the possibility to measure magnetic properties of materials at atomic precision is one of the important goals of today's experimental physics. Researchers propose a new method, utilizing properties of the quantum world - the phase of the electron beam - to detect magnetism with atom-by-atom precision.
