Russian T-50 fighter debuts at air show

The Sukhoi T-50 fifth-generation stealth fighter, which Russia is jointly developing with India, made its public debut at a Moscow airshow on Wednesday. The T-50 resembles Russia’s best-selling Su-30 fighter jet but will have all its weapons hidden inside its body and wings to avoid radar detection and will fly at supersonic cruising speeds. The …

Carbon nanotube transistors could enable large OLED screens

New technology employs organic light emitting diodes, or OLEDs, tiny thin films that create light in response to electrical current. But making OLED displays that are much bigger than a smart phone’s has been problematic. While they consume less power overall, a serious burst of current is needed to fire up each pixel. Transistors that …

Maximum wind and wave power limited by free kinetic energy and maximum wind power extraction would be as bad as doubling atmospheric CO2

Earth System Dynamics journal – Estimating maximum global land surface wind power extractability and associated climatic consequences The availability of wind power for renewable energy extraction is ultimately limited by how much kinetic energy is generated by natural processes within the Earth system and by fundamental limits of how much of the wind power can …

Epitaxial silicene formed on single-crystalline ZrB2 thin Films: structure and electronic properties

The experimental realization of extended, two-dimensional sheets of silicene, the silicon counterpart of graphene, has been elusive so far. Researchers have demonstrated that such a two-dimensional, epitaxial honeycomb Si layer forms through surface segregation on a metallic zirconium diboride (ZrB2) Film grown itself epitaxially on Si(111). The honeycomb Si layer uniformly covers the ZrB2(0001) surface …

Saudi Arabia and OPEC should lower oil prices to reduce political unrest in the middle east

Saudi Arabia and other OPEC nations should lower oil prices to reduce political unrest. The reason is that high oil prices are increasing the price for food and inflation and high costs of basic items is one of the driving forces behind the political unrest that threatens Saudi Arabia. Saudi Arabia and the OPEC nations …

Bioengineered veins could help patients needing bypass surgery, dialysis

Vein drain: Using human cells, scientists have grown shelf-stable blood vessels, like this six-millimeter-diameter model, that they hope to eventually see used as grafts for heart surgeries and hemodialysis. Credit: Science/AAAS New research published in the current issue of the journal Science Translational Medicine demonstrates the capability of tissue-engineered vascular grafts that are immediately available …
