Only a little way outside the plumes, however, the droplets measured more than 25 microns across.
By 1995 its Pentium Pro packed 5.5 million transistors, some as small as 0.35 microns wide.
In 1998 chipmakers took up so-called deep ultraviolet light, which has a wavelength of 0.248 microns.
By 1995 its Pentium Pro packed in 5.5 million transistors, some at 0.35 microns wide.
Between these two layers is a water-soluble polymer coating less than 10 microns thick.
These strands of silk, just 3 microns wide, are three times as tough as DuPont's bulletproof Kevlar.
The proton then travels through a film just 18 microns thick to oxygen on the other side.
This year's Pentium III is up to 28 million transistors, which are down to 0.18 microns wide.
From there engineers hope to use still-tinier wavelengths the "extreme ultraviolet" light waves that measure 0.013 microns.
Makers then aim to move to even deeper ultraviolet light waves that are only 0.19 microns long.
"They're smaller than the diameter of a human hair, less than 100 microns in size, " explains Dr Lane.
The N95 blocks 95% of particles bigger than 0.3 microns, or one-three-hundredth the width of a human hair.
The Vellus Aureum wool fibers must measure a mere 13.9 microns (closer to the fineness of a cobweb).

From there the engineers hope to use still-tinier wavelengths--the "extreme ultraviolet" light waves that measure just 0.013 microns.
In the late 1980s they turned to ultraviolet light, which has a shorter wavelength (0.435 microns and smaller).
Dr Adelberger has confirmed that Newton's predictions are correct down to 44 microns.
It will remove algae and other biological matter as small as two microns.

That is far wider than is needed to accept a wavelength of natural light, which spans only 0.6 microns.
In the late 1980s they turned to ultraviolet light, which has a shorter wavelength (0.435 microns and even smaller).
If you bumped it up to 125 microns an easily breakable sphere would be yours in about 24 hours.
It consists of a disk with holes around its edge hanging horizontally from a cord, microns above another, similarly perforated plate.
The new printer has a resolution of 100 microns, by comparison, the original Replicator had a layer resolution of 270 microns.

The bottom layer has hundreds or thousands of tiny intersecting liquid-handling channels, each about the width of a human hair (100 microns).
The tiny beads flatten out to form ten layers of sheets 15 microns thick, which are stacked and cooled to 100 degrees.
In the mid-1980s the smallest features on chips were 1 or 2 microns wide, about one-hundredth the width of a human hair.
To get around this, researchers piped water through sealed tubes just 50 microns (millionths of a metre) in diameter, between individual layers.
These channels, which have a diameter of 50 microns (about the width of a human hair) are etched using standard silicon-fabrication methods.
Even though we've seen high resolutions out of machines like the Replicator 2, the difference 25 microns makes is practically indistinguishable.
Most ash particles are normally 50-100 microns (millionths of a metre) across.
