The XRD characteristic spectra of Ni:ZnO thin films reveal that the required phase is present with a little amount of impurities that matches well with the JCPDS data indicating the hexagonal structure. The particle sizes measured by the XRD Scherer's formula, values of lattice constants and the...
More particularly, such phosphorus-containing compounds have the characteristic formulae; ##STR2## wherein each R is the same or different, and each R is independently a divalent organic radical directly bonded to the phosphorus atom through a carbon-phosphorus bond, said divalent radical being ...
This MS work showed the presence of a number of amino acid residues with an experimental mass of 100.064 Da having a molecular formula of C4H8N2O, thereby suggesting the presence of α,γ-A2bu moieties in the peptide. A high resolution molecular ion MH+ value of 1,157.7370 (monoisotopic) ...
Based on the crystal structure determined at 2.64 Å, rational design of M2 was conducted, giving rise to the mutant M3 (A216V/K238N/L122A). The kcat/KM value of the mutant M3 is 21.6-fold higher than that of Est816. Furthermore, activity assays demonstrated that M3 reached 99%...
but the formula used to calculate the distortion does not take into account this difference in the angles between atoms. So the actual distortion calculated for Bi0.5Sb0.5sample is expected to be different. Although we expected that the alloy of Bi3+or Sb3+with In3+is expected to distort mo...
