Explosive silicon in MEMS?

Mr_Farlops writes "Serendipity struck for chemists at the University of California, San Diego, after a chip of porous silicon, laced with gadolinium nitrate, exploded after being scratched. An article in the EE Times describes the nature of this discovery and speculates about the possible uses of the substance in microscopic rockets and explosive charges. It also sets the mind daydreaming about tiny fuses made of nested nanotubes filled with fuel and oxidizers."
