Lost radio contact leaves pilots on their own

Article Abstract:

The air traffic controllers lost voice contact with 400 airplanes they were tracking over the southwestern United States as the main voice communication system shut down unexpectedly. However, the tragedy was averted by quick thinking controllers who used their cell phones to alert other traffic control centers and airlines themselves that airplanes were on a collision course.

The great gallium nitride gamble

Article Abstract:

The blue semiconductors were previously built on substrates of sapphire or silicon carbide. The substrates form the key to blue or ultraviolet semiconductor lasers, which would be the cornerstone of major new industrial, and consumer electronic goods, and also next generation DVD player-recorders and optical data-storage systems for computers.

A promising lithography gets struck: electron projection is just not fast enough

Article Abstract:

The number of wafers that a lithographic tool can process in an hour determines how fast a semiconductor manufacturer can build ICs. Semiconductor manufacturers expect it to process 30 wafers per hour.
