Stories about: light absorption

Polymer Solar Cells More Efficient than Ever Iowa State University along with Ames Laboratory researchers, have successfully developed a process that produces a thin and uniform light-absorbing layer on textured surfaces, thus improving the performances of polymer solar cells in light absorption.Sumit Chaudhary, an Iowa State assistant professor of electrical a... 3 December 2010 08:45 GMT New Quantum Cascade Laser Created! Quantum Cascade Laser systems represent semiconductor lasers that have the ability to emit light in the mid and far-infrared wavelengths of the electromagnetic systems. They are usually used to make spectroscopic analysis, such as measuring gases concentration in the Earth's atmosphere, as sensors for cruise con... 8 February 2008 07:07 GMT Dark Field Images Sharper than X-Ray X-ray imaging has been serving our medical and industrial needs for more than a century, but it has a series of disadvantages that makes its use rather obsolete. For example, it can only produce a 2D image of the probed sample, cannot diagnose certain diseases, such as breast cancer or Alzheimer, nor metal fatigue as... 21 January 2008 02:57 GMT
