Nobel Prize In Physics goes to Blue LED

2014 Nobel Prize In Physics Awarded To the Inventors of the Blue LED posting says that the 2014 Nobel Prize in Physics has been awarded to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura, the inventors of the blue LED. When Isamu Akasaki, Hiroshi Amano and Shuji Nakamura produced bright blue light beams from their semi-conductors

Researchers Develop Purely Optical Cloaking

Technologies for making things invisible is always interesting. There are active and passive technologies that have been tried for this. My earlier posting Mercedes uses LEDs to create invisible car showed and active technology that used camera + huge LED display to make invisibility effect. Yesterday I saw a new interesting passive one. Researchers Develop


Spintronics is an emerging technology exploiting both the intrinsic spin of the electron and its associated magnetic moment, in addition to its fundamental electronic charge, in solid-state devices. Spintronics differs from the older magnetoelectronics, in that the spins are not only manipulated by magnetic fields, but also by electrical fields. Spintronics emerged from discoveries in
