The directionality and relative strengths of hydrogen bonds to monocyclic aromatic heterocycles were investigated using crystal structure data and theoretical calculations. Surveys of the Cambridge Structural Database for hydrogen bonds between C( sp 3)(SINGLE BOND)O(SINGLE BOND)H and aromatic fragment...

Chemical looping reforming (CLR) provides a viable process intensification approach for clean and efficient syngas production from carbonaceous fuel with inherent gas–gas separation. The rational design of metal oxide-based oxygen carriers and the scale-up of associated CLR reactor systems play important...
NH4V4O10 is composed of stacked V4O10 units along the a-axis and forms a stable bilayered structure by sharing edges of vanadium octahedra, in which the NH4+ develop N–H⋯O hydrogen bond interactions with adjacent oxygen atoms between the layers and thereby enhancing the structural stability...
From a macroscopic view, the heat released by hydrogen combustion can be used as energy. From a molecular view, the reactions include several steps: breaking of the H–H and O–O bonds and formation of the H–O bond. Electron transfer also occurs in this process. Because of the picosecond...

The comparison of the Raman spectra of SO and SGO can reveal that (i) the Raman bands for SGO, which are associated with Sn-O symmetric stretching mode, shift to lower frequency in comparison with that for SO, indicating the relatively weak bond strength and long bond length of Sn-O ...
