Different bonds absorb the IR energy at different frequencies, and hence their presence can be identified by the peak absorption in the absorption spectrum. The peak absorption of the carbon–carbon double bond is reduced in height after polymerization. The ratio between pre- and postpolymerization ...
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 ...
The greater the deformation of bond-lengths and bond-angles in the vicinity of the impurity, the higher the energy required to form the defect. This leads to the reality of very low equilibrium solubility of dopants in bulk diamond. 5.1.6 Other Forms of Carbon Condensation of carbon ions ...
Energy barriers and chemical properties in the coadsorption of carbon monoxide and oxygen on Ru(0001) Understanding the interactions and behavior of the coadsorption of different atomic and molecular species on surfaces is fundamental to many important surf...

ATP releases free energy when its phosphate bonds are broken, and thus supplies ready energy to the cell. More ATP is produced in the presence of oxygen (O2) than in pathways that do not use oxygen. The overall reaction for the conversion of the energy in glucose to energy stored in ATP...
we demonstrated the applicability of various nucleophiles such as halides, oxygen, sulfur, phosphorous and carbon nucleophiles for the synthesis of β-substituted trifluoropropylamines. The developed methodology offers a versatile synthetic tool to build high structural diversity on trifluoropropyl backbone...
Inversely, larger Rh particles are favored when dispersed on high oxygen ion lability support (Rh/CZ). Lastly, the apparent activation energy, Ea of methane formation increases monotonically as support OSC increases [46]. 3.1.1.3 Pd Due to the capability to dissociate H2 and distribute H atoms...
The Element proportions of NCDs were 57.87% of carbon, 16.22% of nitrogen and 25.91% of oxygen. The high-resolution C1s spectra (Fig. 2B) exhibited four peaks at 284.73, 286.28, 287.73 and 288.63 eV, corresponding to C=C/C-C, C-N, C-O/C-O-C and C=O groups, respectively [29,...
line edge roughness and slope pattern are improved when an ultrafine photoresist pattern is formed using photoresist copolymer having a multi-oxygen-containing compound as a repeating unit such as an ethyleneoxy moiety represented by Formula 1 with at least one polymerizable carbon-carbon double bond....
