EnergyLink Ltd. Welcome Carbon Emissions Reduction Target (CERT) Extension

The Carbon Emissions Reduction Target (CERT) is an obligation on all Energy Suppliers with more than 50,000 customers to reduce carbon emissions in domestic households. The scheme came into effect in April 2008 and was due to end in March 2011. The obligation falls on six main Energy Suppliers: British Gas, NPower, E.ON, EDF, Scottish Power and Scottish & Southern Energy.
There are several ways in which carbon emissions can be reduced including heating, lighting, appliances and micro-generation. However, the most effective measure is Home Insulation which has accounted for 62% of the overall savings made since CERT began. Loft Insulation and Cavity Wall Insulation in particular account for the vast majority of the installations.
The Energy …

Magnets trump metallics

Metallic carbon nanotubes show great promise for applications from microelectronics to power lines because of their ballistic transmission of electrons. But who knew magnets could stop those electrons in their tracks?
Rice physicist Junichiro Kono and his team have been studying the Aharonov-Bohm effect — the interaction between electrically charged particles and magnetic fields — and how it relates to carbon nanotubes. While doing so, they came to the unexpected conclusion that magnetic fields can turn highly conductive nanotubes into semiconductors.
Their findings are published online this month in Physical Review Letters.
“When you apply a magnetic field, a band gap opens up and it becomes an insulator,” said Kono, a Rice professor in electrical and computer engineering …

New Laser Cutting Processes for CFRP- Materials

The Laser Zentrum Hannover e.V. (LZH) is working on a new laser cutting process for CFRP materials, which compensates for thermal damage occurring at the cutting edges, such as exposed carbon fibers and evaporated or melted polymatrix. Following the laser cutting, the cut kerf is coated with a powdery filler material which melts and thus seals the edge, making it a high-quality cut.
Carbon fiber reinforced polymers (CFRP) are being increasingly used as a construction material in the automotive and aerospace industry, as well as for wind energy and even in the field of sports and leisure activities.
Conventional machining processes such as mechanical and water jet cutting are no longer able to meet the demands for …
