Fourier-transformed infrared spectroscopy (FTIRX-ray photoelectron spectroscopy (XPSB–C–N thin films of a wide composition range were deposited by reactive DC magnetron sputtering of targets with different B/C ratios in an Ar/N 2 atmosphere. The bonding characteristics of these amorphous films ...
The precursor-derived Si-B-C-N and B-C-N ceramics are of special interest because of their covalent bonding providing mechanical reliability and high-temperature stability. In general, the precursor-derived ceramics posses several advant... O Tsetsgee,K Müller - Uni Stuttgart - Universitäts...
Ferromagnetic Bonding: Properties of High-Spin Lithium Clusters n +1 Li n ( n = 2−12) Devoid of Electron Pairs Density functional calculations are used to generate a series of the maximum-spin lithium clusters Li-n+1(n) (n=2-12). These clusters do not possess any el... SD Visser...
The chemical bonding within a specimen annealed at 1800 °C was investigated by X-ray photoelectron spectroscopy (XPS). In Fig. 9a, the peaks at 102.1 and 100.58 eV on Si 2p spectrum are assigned to Si–N, and Si–, respectively, which is consistent with presence of the SiC and Si3N4...
The chemical composition and bonding structures of B-C-N-H films fabricated by medium frequency magnetron sputtering, with N2+CH4+Ar gas mixture sputtering the boron target, were investigated. XPS and FTIR spectrometric analyses show that the increase of CH4 flow rate during deposition causes an ...

X-ray crystallography demonstrated that the imidazopyridine interacted with a carbonyl and an amino group of Val135 as a hydrogen-bonding donor and as a hydrogen-bonding acceptor. In contrast, 7-hydroxybenzimidazoles interacted with Asp133 and Pro136. Microsomal mouse stability studies were performed...
