In celebration of the 2014 Nobel Prize in Physics, aapt has developed how to win 50 gems in dragon city a new resource to help its members and the physics community teach about the science behind the Nobel Prize.
The Physics Teacher and the American Journal of Physics.

Researchers had struggled for years to grow high-quality gallium nitride crystals and repeatedly failed to create a p-type layer.
Nakamura developed an alternate method, growing a thin layer of gallium nitride at a low temperature before growing subsequent layers at a higher temperature.Blue LED was much harder to produce as compared to the other two.Unlike the previous lighting technologies, an LED produces light directly, instead of generating."With the International Year of Light in 2015, the world will be celebrating LEDs and their efficient, commercial applications for general lighting, high-tech research and life-saving medicines he added.Their work and discoveries range from cancer therapy and laser physics to developing proteins that can solve humankinds chemical problems.quot;s from AIP Leadership and Journal Editors.
In this kind of prize we really emphasize the usefulness of the invention.
Even though it was invented in its practical form 20 years ago, the blue LED was long sought after missing link of lighting technology, due to which LED lamps were made possible, yet it eluded the scientists and engineers for 30 years.
Until now lighting technology have been an inefficient and heavy energy consuming process.
