Fully Printed Carbon Nanotube Transistor Circuits for Displays

Organic light-emitting diode (OLED)-based displays are used in cell phones, digital cameras, and other portable devices. But developing a lower-cost method for mass-producing such displays has been complicated by the difficulties of incorporating thin-film transistors that use amorphous silicon and polysilicon into the production process.

How Terrain and Turbine Placement Affect Wind Energy Production

A miniature turbine measuring just 10 inches high is helping a research team led by Hui Hu - an Iowa State University associate professor of aerospace engineering - understand how hills, valleys, and the placement of turbines affect the productivity of onshore wind farms.

Low-Power Quantum Computers

By 2017, quantum physics will help reduce the energy consumption of computers and cellular phones by up to a factor of 100. For research and industry, the power consumption of transistors is a key issue. The next step will likely come from tunnel-FET, a technology that takes advantage of a phenomenon referred to as quantum tunneling. At the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland, research is well underway.

Voltage Increases Observed in Closely Packed Nanowires

Unexpected voltage increases of up to 25 percent in two barely separated nanowires have been observed at Sandia National Laboratories. Designers of next-generation devices using nanowires to deliver electric currents — including batteries and certain solar arrays — may need to make allowances for such surprise boosts.

Thinner Thermal Insulation for Better Energy Savings

In order to lower energy costs, more and more homeowners are investing in insulation facades. But the typical insulation layers on the market have one drawback: they add bulk. The thick outer skin changes the building’s visual appearance and can result in significant follow-up costs – with a need to fit new, deeper window sills and sometimes even roof extensions.

Bacteria Engineered to Eat Switchgrass and Make Transportation Fuels

Researchers with DOE’s Joint BioEnergy Institute (JBEI) have engineered the first strains of Escherichia coli bacteria that can digest switchgrass biomass and synthesize its sugars into all three of those transportation fuels. The microbes are even able to do this without any help from enzyme additives.
