Carbon isotopes of lipids ( n-alkanes ) derived from leaf wax and lignin, and total organic carbon from two sections of lake sediments interbedded with the in eastern North America have shown carbon isotope excursions similar to those found in the mostly marine St. Audrie ’ s Bay section, Somerset, England ; the correlation suggests that the end-Triassic extinction event began at the same time in marine and terrestrial environments, slightly before the oldest basalts in eastern North America but simultaneous with the eruption of the oldest flows in Morocco ( Also suggested by Deenen et al., 2010 ), with both a critical greenhouse and a marine biocalcification crisis.

Carbon and stainless spring steel wire have significant applications for engineered springs for critical automotive or industrial manufactured parts / components.

Carbon from this type of clathrate is isotopically heavier ( δ < sup > 13 </ sup > C is-29 to-57 ‰) and is thought to have migrated upwards from deep sediments, where methane was formed by thermal decomposition of organic matter.

Carbon brakes have occasionally been applied to road cars, by the French Venturi sports car manufacturer in the mid 1990s for example, but need to reach a very high operating temperature before becoming truly effective and so are not well suited to road use.

Carbon County has a rich history, some interesting people have passed through her mountains, including Count Zinzendorf, Moravian mystic ; John James Audubon, Benjamin Franklin and many more.

In 2002, Calgon Carbon Corporation planned to construct a carbon reactivation plant in the airpark, though those plans have been delayed due to environmental concerns.

Scofield, sustained by several mines in Pleasant Valley, was still the largest town in Carbon County in 1915, when its citizens made an attempt to have the county seat moved to their community from Price, Utah.

Older applications written with the Carbon API have a potential issue when being ported to the current Intel Macs.

Carbon fibers derived from Polyacrylonitrile ( PAN ) are turbostratic, whereas carbon fibers derived from mesophase pitch are graphitic after heat treatment at temperatures exceeding 2200 C. Turbostratic carbon fibers tend to have high tensile strength, whereas heat-treated mesophase-pitch-derived carbon fibers have high Young's modulus ( i. e., high stiffness or resistance to extension under load ) and high thermal conductivity.

Carbon forks have become very common on racing bicycles of all frame materials.

This view is disputed and relates to a Carbon date from a standing stone setting which intersects with a later timber post circle, the theory being that the stone in question could have been moved and re-set in its original position at a later date.

Carbon shafts have the advantage that they do not bend or warp, but they can often be too light weight to shoot from some bows and are expensive.

Carbon fiber bows have become very popular, and some of the better carbon fiber bows are now comparable to fine pernambuco sticks.

Carbon nanobuds are a newly created material combining two previously discovered allotropes of carbon: carbon nanotubes and fullerenes.

Carbon fibers and PF fibers are noted as two resin-based fibers that are not thermoplastic, most others can be melted.

Carbon steel consists of two components: pure iron, in the form of ferrite, and cementite or iron carbide, a compound of iron and carbon.

With this accounting, there are essentially two levels of Carbon neutral: Either all direct and indirect emissions, or only direct emissions.

Carbon block suppressors are similar to gas arrestors ( GDTs ) but with the two electrodes exposed to the air, so their behavior is affected by the surrounding atmosphere, especially the humidity.
