Bioprinting methods on 2-D surfaces to link 3-D cellular structures Posted: 21 Jul 2014 12:19 PM PDT New research focuses on the development of a novel, matrix-free method for generating 3-D cell spheroids that are combining knowledge from bioprinting methods on 2-D surfaces to link 3-D cellular structures.

Understanding graphene's electrical properties on an atomic level Posted: 21 Jul 2014 12:19 PM PDT For the first time, researchers have used a cutting-edge microscope to study the relationship between the atomic geometry of a ribbon of graphene and its electrical properties.

Chemists eye improved thin films with metal substitution Posted: 21 Jul 2014 10:20 AM PDT The yield so far is small, but chemists have developed a low-energy, solution-based mineral substitution process to make a precursor to transparent thin films that could find use in electronics and alternative energy devices.

Carbyne morphs when stretched: Calculations show carbon-atom chain would go metal to semiconductor Posted: 21 Jul 2014 09:40 AM PDT Applying just the right amount of tension to a chain of carbon atoms can turn it from a metallic conductor to an insulator. The research has implications for mechanically activated nanoscale electronics and optics.

Tiny laser sensor heightens bomb detection sensitivity Posted: 20 Jul 2014 05:43 PM PDT Researchers have created a plasmon laser detector that can sniff out tiny traces of airborne molecules of explosives. The sensor detected both DNT and ammonium nitrate at concentrations below one part per billion.

Fires are major cause of wind farm failure, according to new research Posted: 16 Jul 2014 04:46 PM PDT Fire is the second leading cause of accidents in wind turbines, after blade failure, according to research. Wind farming is one of the leading industries in the renewable energy sector. However, the industry faces a number of challenges, such as opposition by wind farm lobbyists. Today's research suggests that incidents of wind turbines catching fire are a big problem that is not currently being fully reported.
