| Which Structure has optimal resistive switching characteristics? Posted: 08 Aug 2014 08:18 AM PDT Researchers fabricated Pt/TiOx/ZnO/n+-Si structures and investigated the effects of TiOx interlayer with different thickness on the resistance switching of Pt/TiOx/ZnO/n+-Si structures.       |
| Scientists enhance synthesis of chromium dioxide (100) epitaxial thin film growth Posted: 08 Aug 2014 08:18 AM PDT High quality CrO2 film on the (100)-oriented TiO2 substrate was fabricated by using a simple route under ambient pressures. The film shows preferential orientation along (100) direction and has a Curie temperature Tc = 396 K. The resistivity of the film is studied down to about 0.6 K and can be fitted with Á(T)=Á0+AT2exp(-"/T). The magnetization of the film becomes saturated in a relatively low field and follows Bloch's T3/2 law.  |
| Electrons moving in a magnetic field exhibit strange quantum behavior Posted: 08 Aug 2014 08:07 AM PDT Researchers have made the first direct observations of free-electron Landau states -— a form of quantized states that electrons adopt when moving through a magnetic field- — and found that the internal rotational dynamics of quantum electrons, or how they move through the field, is surprisingly different from the classical model, and in line with recent quantum-mechanical predictions.  |
| Flood risk visualization software Posted: 07 Aug 2014 06:55 PM PDT New flood information visualization software will be an excellent tool for water resources planning and management as well as for better flood decision making analysis.  |
| Co-crystals successfully turn liquids into solids Posted: 07 Aug 2014 09:14 AM PDT A new approach for formulating the active chemical ingredients of common drugs and agricultural products has been developed, and it holds broad potential to make such products more durable, safer, cheaper, easier to manufacture and less harmful to the environment.  |
| Solid-state chemistry: Safer and much cheaper methods for extracting metals Posted: 07 Aug 2014 09:14 AM PDT A team of researchers is developing new approaches to chemical synthesis and mineral processing based on solid-state chemistry -- and inspired by examples from nature. The unconventional approaches promise better, safer and far less expensive methods for extracting metals from mineral ores as well as for the scalable synthesis of pharmaceutical drugs.  |
