One-atom-thin silicon transistors hold promise for super-fast computing Posted: 03 Feb 2015 01:01 PM PST Researchers have created the first transistors out of silicene, the world's thinnest silicon material. This new 'wonder material' could make computers and other electronics more efficient.

Penta-graphene, a new structural variant of carbon, discovered Posted: 03 Feb 2015 11:23 AM PST Researchers have discovered a new structural variant of carbon called 'penta-graphene' -- a very thin sheet of pure carbon that has a unique structure inspired by a pentagonal pattern of tiles found paving the streets of Cairo.

Rarely understood ammonium carbonate monohydrate Posted: 03 Feb 2015 10:32 AM PST New structural studies of the superficially simple ammonium carbonate monohydrate could shed light on industrial processes, biochemistry and even the interstellar building blocks of life.

Artificial blood vessels: Tri-layered artificial blood vessels for first time Posted: 03 Feb 2015 08:19 AM PST By combining micro-imprinting and electro-spinning techniques, researchers have developed a vascular graft composed of three layers for the first time. This tri-layered composite has allowed researchers to utilize separate materials that respectively possess mechanical strength and promote new cell growth - a significant problem for existing vascular grafts that have only consisted of a single or double layer.

Potential for graphene and other 2D crystals in the energy sector Posted: 03 Feb 2015 06:43 AM PST Graphene has many potential applications, among them energy generation, conversion and storage. Graphene – a single layer of carbon atoms – and related two-dimensional crystals combine high electrical conductivity with physical flexibility and a huge surface to weight ratio. Such qualities make them suitable for storing electric charge in batteries and supercapacitors, and as catalysts in solar and fuel-cell electrodes.

Singapore's first 3-D-printed concept car Posted: 03 Feb 2015 06:41 AM PST University students have built Singapore's first urban solar electric car with an innovative 3D-printed body shell that has 150 parts. Mounted on a carbon fibre single shell chassis, the NTU Venture (NV) 8 will race in the Urban Concept category at this year's Shell Eco-marathon Asia.

New technique doubles the distance of optical fiber communications Posted: 03 Feb 2015 06:41 AM PST A new way to process fibre optic signals could double the distance at which data travels error-free through transatlantic sub-marine cables. The new method has the potential to reduce the costs of long-distance optical fibre communications as signals wouldn't need to be electronically boosted on their journey, which is important when the cables are buried underground or at the bottom of the ocean.
