New research has demonstrated how glass can be manipulated to create a material that will allow computers to transfer information using light. This development could significantly increase computer processing speeds and power in the future.
A new study reveals the need to rethink one of science's building blocks and, with it, how some of the basic principles underlying the behavior of matter are taught in our classrooms. The researchers examined the way that a phase change, specifically the melting of a solid, occurs at a microscopic level and discovered that the transition is far more involved than earlier models had accounted for.
Gallium nitride is difficult to produce and difficult to handle - and the key to the development of blue LEDs, which won this year's Nobel Prize in Physics. Now, researchers and engineers around the world are working on analyzing and optimizing this material.
Wissenschaftler des Leibniz-Institutes für Photonische Technologien konnten nachweisen, dass Silizium-Nanopartikel biologisch abbaubar sind. Damit eröffnen sich neue Anwendungsfelder in der Medizin - beispielweise in der Therapie und Diagnose von Krebs.
The standard technique, using a top and a bottom gate, can lead to damaging of the graphene layer. This is avoided in the new method, which also offers linear I-V characteristics at low gate voltage. The two-top-gate structure is expected to be a practical route to a room-temperature terahertz source.
Electronic devices waste a lot of energy by producing useless heat. This is one of the main reasons our mobiles use up battery power so quickly. Researchers have made a leap forward in understanding how this happens and how this waste could be reduced by controlling energy flows at a molecular level.
A new class of low-cost polymer materials, which can carry electric charge with almost no losses despite their seemingly random structure, could lead to flexible electronics and displays which are faster and more efficient.
What began as research into a method to strengthen metals has led to the discovery of a new technique that uses a pulsing laser to create synthetic nanodiamond films and patterns from graphite, with potential applications from biosensors to computer chips.
For the first time, researchers have been able to integratively mimic the shape, size, flexibility and surface chemistry of real blood platelets on albumin-based particles. The platelet mimics halt bleeding in mouse models 65 percent faster than nature alone.
