They're made from silica. Why not structures from cars like that?

When you are in Britain you are not required to assimilate or become British for people to consider you one of them.

The subject me and the object the scheme of things fuse into oneness, an experience nobody can say, I am denied of, an experience common to all and sundry.

If a reversed order of running of the compounds is desired, an apolar stationary phase should be used, such as C18 functionalized silica.

The group gels. And it changes from a group of highly motivated but fairly individually centric people into something larger, into a tribe that becomes aware of its own existence.

These four drivers are fusing together and creating the big shift away from the 20th century, defined by hyper consumption, towards the 21st century, defined by collaborative consumption.

Dry water actually consists of 95 percent liquid water, but the silica coating prevents the water droplets from combining and turning back into a bulk liquid.

Glass for flat glass has a higher magnesium oxide and sodium oxide content than container glass, and a lower silica, calcium oxide, and aluminium oxide content.

This complex primitive pattern has, however, been simplified to various degrees in the great majority of vertebrates, as bones have either fused or vanished entirely.

Generally speaking, more mafic magmas, such as those that form basalt, are hotter and less viscous than more silica rich magmas, such as those that form rhyolite.

The duration that a star spends on the main sequence depends primarily on the amount of fuel it has to fuse and the rate at which it fuses that fuel, i.e.

For instance, reagent quality water must have very low levels of impurities such as sodium and chloride ions, silica, and bacteria, as well as a very high electrical resistivity.

While, in birds, these various bones have fused into a single structure, in mammals most of them have disappeared, leaving an enlarged dentary as the only remaining bone in the lower jaw the mandible.

Toothpaste typically has small particles of silica, aluminum oxide, calcium carbonate, or calcium phosphate to grind off stains formed by colored molecules that have absorbed onto the teeth from food.
