The present data suggest that VDR gene Fok I and Cdx-2 polymorphisms contribute to the determination of BMD in Slovak postmenopausal women and can probably be used with other genetic markers together to identify individuals at high risk of osteoporosis.A facile strategy is proposed to prepare N-doped mesoporous carbon catalysts dispersed with Fe3Pt intermetallics (Fe3Pt/N@C) through direct pyrolysis of Pt-Fe co-functionalized ZIF-8. The catalysts exhibit excellent ORR activity, outstanding mass activity with ultralow Pt loading, low H2O2 yield, and high cycling stability in alkaline medium.Second order Jahn-Teller (SOJT) effects arise from interactions between filled and empty molecular orbitals of like symmetry. These interactions often lead to structural distortions whose extent is inversely proportional to the energy difference between the interacting orbitals. The main objectives of the work described here are (1) the calculation (using density functional theory methods) of the energies of the valence molecular orbitals in the species EH3 (E = N, P, As or Sb), HEEH (E = C, Si, Ge or Sn), and H2EEH2, (E = C, Si, Ge or Sn) and (2) the correlation of these energies with barriers for planarization or linearization. The calculations suggest an upper limit of about 12 eV energy separation of the interacting levels for SOJT effects to be significant, which is considerably larger than previously thought and implies that SOJT effects may be more common than currently realized.Understanding the mechanism of the insulator-metal transition (IMT) in VO2 is a necessary step in optimising this material's properties for a range of functional applications. Here, Rietveld refinement of synchrotron X-ray powder diffraction patterns is performed on thermochromic V1-xWxO2 (0.0 ≤ x ≤ 0.02) nanorod aggregates over the temperature range 100 ≤ T ≤ 400 K to examine th
