sources of inorganic carbon are limestones, dolomites and carbon dioxide, but significant quantities occur in organic deposits of coal, peat, oil, and...

as with many carbon deposits it contains trace amounts of carbon allotropes such as graphene sheets and fullerenes. The Shunga deposit contains an estimated...

produces atomic carbon as waste. However, difficulties maintaining its temperature of up to 600 °C and properly handling carbon deposits mean significantly...

albedo when deposited on snow and ice (direct effects) and indirectly by interaction with clouds, with the total forcing of 1.1 W/m2. Black carbon stays in...

source of available carbon in the carbon cycle, atmospheric CO2 is the primary carbon source for life on Earth. In the air, carbon dioxide is transparent...

combustibility and deposit forming tendencies of the fuel. The Ramsbottom test is used to measure carbon residues of an oil. In brief, the carbon residue of a...

comparison of carbon-14 levels in a sample, with tree ring or cave-deposit carbon-14 levels of a known age, then gives the wood or animal sample age-since-formation...

properties of deposited metal. Activated carbon treatment removes such impurities and restores plating performance to the desired level. Activated carbon is used...

after the ice has melted, they start absorbing more heat. Local black carbon deposits on snow and ice also contribute to Arctic warming. Arctic surface temperatures...

overheated oil inside the compressor, it breaks down into carbon deposits.  These carbon deposits will develop in the bearing, which can lead to less efficient...

Fusain is a fossilised carbon deposit which, after some controversy, has been identified as fossilised charcoal. It is fibrous, black and opaque, and often...

from Italian mechanics in the 1950s using this practice to burn off carbon deposits from the spark plugs of sports cars. However, modern direct injection...

oil and gas did not originate from fossil deposits, but have instead originated from deep carbon deposits, present since the formation of the Earth....

portion of exhaust gases, over time the valve can become clogged with carbon deposits, which will prevent it from operating properly. Clogged EGR valves...

Graphite (/ˈɡræfaɪt/) is a crystalline allotrope (form) of the element carbon. It consists of many stacked layers of graphene typically in the excess of...

Carbon is a primary component of all known life on Earth, and represents approximately 45–50% of all dry biomass. Carbon compounds occur naturally in great...

deposits Collapse breccia pipe deposits Volcanic deposits Surficial deposits Metasomatite deposits Metamorphic deposits Lignite Black shale deposits Other...

increased carbon deposits in GDI engines. Third party manufacturers sell oil catch tanks which are supposed to prevent or reduce those carbon deposits. The...

subterranean carbon deposits in the decay of ancient plants. The ground floor was specifically designed to display the products of Union Carbide and Carbon's subsidiaries...

The carbon cycle is that part of the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere...
