Carbon-oxygen double bondPseudographic structureSodium-ion batteriesAnodeOxygen-containing functional groups and pseudographic structure are key factors that affect the electrochemical properties of biomass derived carbon materials. In this work, the shaddock peel derived hard carbon with abundant carbon-...
结果1 题目 The groups that consists of oxygen and carbon joined by a double bond is called the carbonyl group. If the carbonyl group is at the end of the molecular skeleton it is called a(n) 相关知识点: 试题来源: 解析 aldehyde. 反馈 收藏 ...
A strong linear relationship was observed between the average double bond equivalence (DBE) and the ratio of carbon to oxygen atoms in oxygenated compounds of dissolved organic matter (DOM). Data were acquired by a Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR MS), equipped ...
Study of double bond equivalents and the numbers of carbon and oxygen atom distribution of dissolved organic matter with negative-mode FT-ICR MS. A strong linear relationship was observed between the average double bond equivalence (DBE) and the ratio of carbon to oxygen atoms in oxygenated compou...
260 Recently, the same authors have found that the polymerization of isobutylene by AlEtCl2 was totally inhibited by the simultaneous presence of a hindered pyridine (to prevent cocatalysis) and of oxygen. This effect was claimed to prove that the mechanism of direct initiation involved the ...

Synthesis and photooxygenation of angular furocoumarins: isopsedopsoralen and allopsoralen temperature gave the photo-cleaved product, o -benzoylhydroxy derivatives, through [2+2] cycloaddition of singlet oxygen with the double bond of the furan... S El-Gogary,N Hashem,MN Khodeir - 《Research on...
Binding of carbon monoxide and oxygen to sterically protected heme model compounds (basket-handle porphyrins) was investigated in liquid toluene at temperatures from 180 to 300 K by laser flash photolysis. Only a single exponential rebinding process from the solvent could be seen in the time range...
