QuoteScientists have attempted for years to create materials that can eliminate unwanted reflections, which can degrade the performance of various optical components and devices. “We started thinking, there is no viable material available in the refractive index range 1.0-1.4,” Schubert said. "If we had such a material, we could do incredible new things in optics and photonics." So the team created one. Using a technique called oblique angle deposition, the researchers deposited silica nanorods at an angle of precisely 45 degrees on top of a thin film of aluminum nitride, which is a semiconducting material used in advanced light-emitting diodes (LEDs). From the side, the films look much like the cross section of a piece of lawn turf with the blades slightly flattened.
QuotePetrol Ofisi, one of the leading oil companies in Turkey, has said it will include in its diesel fuel an additive from British nanotechnology specialist Oxonica that helps increase gas mileage by 5 percent to 10 percent and cut down nitrogen-based emissions. The change to fuel consumption also helps reduce carbon dioxide emissions. A tour bus company in Britain and another group in the Philippines already incorporate Oxonica's Envirox fuel additive into its diesel fuel. The additive, based on cerium oxide (a powder often used for polishing glass lenses), makes the combustion process more efficient.
