Breakthrough in OLED technology

March 2, 2015 12:27 pm | by Jason Socrates Bardi, American Institute of Physics | News | Comments

Organic light-emitting diodes (OLEDs), which are made from carbon-containing materials, have the potential to revolutionize future display technologies, making low-power displays so thin they'll wrap or fold around other structures, for instance. Conventional LCD displays must be backlit by either fluorescent light bulbs or conventional LEDs whereas OLEDs don't require back lighting.

Scientists of the Univ. of Luxembourg and of the Japanese electronics company TDK report progress in photovoltaic research: They have improved a component that will enable solar cells to use more energy of the sun and thus create a higher current. The improvement concerns a conductive oxide film which now has more transparency in the infrared region.

How eyelash length keeps eyes healthy

February 25, 2015 7:53 am | by Jason Maderer, Georgia Institute of Technology | News | Comments

It started with a trip to the basement of the American Museum of Natural History in New York to inspect preserved animal hides. Later, Georgia Institute of Technology researchers built a wind tunnel about 2 ft tall, complete with a makeshift eye. By putting both steps together, the team discovered that 22 species of mammals are the same: their eyelash length is one-third the width of their eye.
