Researchers from Dresden discover a new material that conducts electric currents without loss of power over its edges and remains an insulator in its interior. The material is made out of bismuth cubes packed in a honeycomb motif that is known from the graphene structure. As opposed to graphene, the new material exhibits its peculiar electrical property also at room temperature and, hence, holds big promises for applications in nanoelectronics.
While scientists have produced simple demonstrations of working carbon nanotube circuit components in the past, a Stanford team was able to demonstrate an actual subsystem composed entirely of the material.
Developing the cleaning procedures and devices necessary for the process took years of research and collaboration with industry. But today it is possible to make contamination in the SEM a thing of the past.
Researchers at the National Institute of Standards and Technology (NIST) have developed a new microscope able to view and measure an important but elusive property of the nanoscale magnets used in an advanced, experimental form of digital memory. The new instrument already has demonstrated its utility with initial results that suggest how to limit power consumption in future computer memories.
Carbon nanotubes and magnetic molecules are considered building blocks of future nanoelectronic systems. Their electric and mechanical properties play an important role. Researchers of Karlsruhe Institute of Technology and French colleagues from Grenoble and Strasbourg have now found a way to combine both components on the atomic level and to build a quantum mechanical system with novel properties.
Durch Zusatz von lediglich 0,5 bis zwei Prozent des Kohlenstoffmoleküls Graphen gelang es, den Flammschutz von Kunststoffen zu optimieren. Damit erweise sich das nur aus einer oder wenigen Atomlagen bestehende Graphen als ein vielversprechender neuer Hilfsstoff für einen halogenfreien Flammschutz von Kunststoffen
IBN researchers have now made it possible for companies to predict the toxicity of new drugs earlier, potentially speeding up the drug development process and reducing the cost of manufacturing. The tool they have engineered to enable this is an artificial human liver piece, which mimics the natural tissue environment closely.
New optical technologies using 'metasurfaces' capable of the ultra-efficient control of light are nearing commercialization, with potential applications including advanced solar cells, computers, telecommunications, sensors and microscopes.
The ultrafast, ultrabright X-ray pulses of the Linac Coherent Light Source (LCLS) have enabled unprecedented views of a catalyst in action, an important step in the effort to develop cleaner and more efficient energy sources.
Researchers have successfully created a magnetic soliton - a nano-sized, spinning droplet that was first theorized 35 years ago. These solitons have implications for the creation of magnetic, spin-based computers.
