| Detection of spin-resolved electronic states from a buried ferromagnetic layer Posted: 23 Jun 2014 06:16 AM PDT Researchers have successfully detected spin-resolved electronic states from a buried ferromagnetic layer, which had been difficult to detect using conventional spin-resolved photoemission spectroscopy.  |
| Posted: 23 Jun 2014 06:16 AM PDT Hydrogen-oxygen fuel cells are the ultimate clean power-generating device, which extract electric power from hydrogen and oxygen with high efficiency and emit only water as waste. However, there are still many challenges to overcome before achieving wide use of this technology. Scientists have now successfully demonstrated a new approach toward a non-precious metal oxygen reduction catalyst for fuel cells.  |
| Formation of organic thin-film transistors through room-temperature printing Posted: 23 Jun 2014 06:16 AM PDT Researchers have established a process for forming organic thin-film transistors (TFTs), conducting the entire printing process at room temperature under ambient atmospheric conditions.  |
| Discovery of pure organic substances exhibiting the quantum spin liquid state Posted: 23 Jun 2014 06:16 AM PDT Researchers have discovered pure organic substances exhibiting the quantum spin liquid state. Water loses kinetic energy as it is cooled, and when water molecules become unable to move, water becomes solid (ice). Similarly, electron spins in magnetic materials normally align and form a solid state at low temperature. Recent theoretical studies suggest that spins on a triangular lattice maintain their liquid state (quantum spin liquid state) even at an extremely low temperature.  |
