Self-Destruct Silicon (Exploding Circuit Boards)

A new discovery implying to be a new "last resort" to security defenses on government computer systems and really important servers. The quote below is from Oracle Magazine

"Those wishing to see a pilfered peripheral taken dead rather than alive may be encouraged by the work of a team of chemists at University Of California, San Diego. Researchers have created computer chips that can ruin the circuitry in anything from a spy plane to a cell phone. It involves applying an oxidizing chemical alled gadolinium nitrate to a permeable silicon chip. When an appropriate electric charge is applyed to the chemical--a detonation command sent to a laptop computer, for example--the chemical rapidly burns the host silicon, melting the chip"
