Using expanded cork dust as a cheaper substitute of fumed silica, the expanded cork/fumed silica composites with hierarchical porous structure were designed and constructed as an alternative lower cost material for vacuum insulation panel (VIP) core.
The dust cloud was a quickly expanding mass of debris that included, among other toxics, large amounts of alkaline pulverized cement, a mucous membrane irritant.
Most of the petcoke in Chicago is shipped in from the nearby BP refinery in Whiting, Ind., which was responsible for last month's Lake Michigan oil spill and is tripling their output of the dangerous dust after expanding their facility.
They explode leaving expanding masses of gas and dust behind, which, when color-corrected by astronomers, makes for some very pretty pictures.
The nebula around the star was formed during its 19th-century brightening and is an expanding shell of gas and dust, shaped like an hourglass with a disk at its centre.
A swiftly expanding burst of smoke and dust hid the rest of lower Manhattan; we saw the collapse of the second tower only on television, where the footage of hellbent airplane, exploding jet fuel, and imploding tower was played and replayed, much rehearsed moments from a nightmare ballet.
The source could have a physical connection to an expanding cloud of gas and dust from an old supernova that appears next to the site of the flares, Hyman notes.
This shock wave sweeps up an expanding shell of gas and dust called a supernova remnant.
We also study dust properties with an expanding X-ray ring from the observation of a distant GRB.
An entitled whiner first seen on "The Real Housewives of Orange County," Jo wasn't technically a housewife: she ultimately broke things off with her live-in fiancé, Slade Smiley, and while her notion of housework was broad enough to accommodate wearing a French maid's costume it never expanded into actually dusting the mantles.
