Carbon and Carbon-CompoundsNot Availabledoi:10.1038/10.1038/022320a0HERSCHELA. SNature
Carbon monoxide is a colorless, odorless, tasteless, flammable, toxic gas.Carbon monoxide is produced when carbon and carbon compounds undergo incomplete combustion. The inefficient combustion of carbon fuels for heating results in the production of carbon monoxide, which may result in high CO concentr...
根据第二段中“There are two basic methods of carbon sequestration: direct and indirect. ”(固碳有两种基本方法: 直接的和间接的。)及“The second method of sequestration—indirect—involves the use of plants that bind CO2 by photosynthesis (光合作用) or when carbon compounds are bound in a soil...
Copper-mediated carbon-carbon and carbon-heteroatom coupling reactions have been known for more than 100 years; however, these reactions have been overshad... LM Huffman,SS Stahl - 《Journal of the American Chemical Society》 被引量: 50发表: 2008年 Carbon–hydrogen and carbon–heteroatom bond ...
Most carbon compounds have low reactivity at ordinary temperature but may react vigorously when heat is applied. For example, cellulose in wood is stable at room temperature, yet burns when heated. As a consequence, organic carbon compounds are considered combustible and may be used as fuels. Exa...
根据第三段的“The carbon cycle is the transfer of carbon through different media.(碳循环是碳通过不同介质的转移。)”和“For instance, carbon released into the atmosphere by the rapid burning of fossil fills back as rain in the form of carbonate (碳酸盐) and is absorbed by the reservoirs (...
One way of doing this is to improve the properties of interfaces between carbon fibers and carbon matrices. In order to do this it is necessary to control microstructures at the interface. The Carbon Alloys project has supported research into the microstructures of interfaces. The concept of the...
解析:The key phrase that indicates how the blank for this question should be completed is “the ability to form an unending series of different molecules.” Among the answer choices, “diversity” and “variety” clearly fit logically with “unending” and “different” and create two very simi...
Carbon flux指的是碳从一个pool流到另外一个pool的过程。Carbon flux is the flow of carbon from one pool to another. It is the net difference between carbon removal and carbon addition. 4.3.U1 Autotrophs convert carbon dioxide intocarbohydratesand other carbon compounds. ...
