Photon scattering off ⁹⁴Zr and ⁹⁶Zr [PDF]

Photon-scattering experiments off the nuclei ⁹⁴Zr and ⁹⁶Zr were performed at the 10-MeV bremsstrahlung facility DHIPS at the super-conducting electron linear accelerator S-DALINAC at Darmstadt. The dipole excitation-strength distributions were determined in an energy range between 2 and 8 MeV, including the 1⁻ quadrupole-octupole coupled Two-Phonon ...

Electronic structures of the Zr-He, Zr-H, and Zr-He-H systems

Physics of the Solid State, 2015
Ab initio calculations of the electronic structures of the Zr-He, Zr-H, and Zr-He-H systems have been carried out. The effect of impurities of hydrogen and helium on the electronic structure of hpc Zr has been considered. It has been found that the 1s states form a narrow band below the conduction band bottom of Zr.

Investigation of Zr, Gd/Zr, and Pr/Zr – doped ceria for the redox splitting of water

International Journal of Hydrogen Energy, 2020
Abstract There is a renewed interest in CeO2 for use in solar-driven, two-step thermochemical cycles for water splitting. However, despite fast reduction/oxidation kinetics and high thermal stability of ceria, the cycle capacity of CeO2 is low due to thermodynamic limitations.

On the Singlet Spectrum of ZrS

Journal of Molecular Spectroscopy, 1998
Three electronic transitions in the singlet manifold of the zirconium sulphide (ZrS) molecule have been rotationally analyzed. They are the B1Pi-X1Sigma+, C1Sigma+-X1Sigma+, and E1Sigma+-X1Sigma+ systems with (0,0) band heads at 924.60, 731.51, and 494.47 nm, respectively.

Low-Temperature Specific Heats of Zr-Ti, Zr-Hf, and Zr-Sc Alloys

Physical Review, 1968
The specific heats of hexagonal Zr-Ti, Zr-Hf, and Zr-Sc alloys were measured at 1.1 to 4.2\ifmmode^\circ\else\textdegree\fi{}K. Maxima in both the electronic specific-heat coefficient $\ensuremath{\gamma}$ and the superconducting transition temperature ${T}_{c}$ were observed at 60 at.% Ti in the Zr-Ti system.

INVESTIGATION OF Zr-ZrN, Zr,Hf-(Zr,Hf)N AND Zr,Nb-(Zr,Nb)N COATINGS DEPOSITED ON A TITANIUM ALLOY SUBSTRATE

High Temperature Material Processes An International Quarterly of High-Technology Plasma Processes
The properties of Zr-ZrN, Zr,Hf-(Zr,Hf)N and Zr,Nb-(Zr,Nb)N coatings deposited on a Ti6Al-4V titanium alloy substrate were studied. It has been established that the introduction of hafnium increases, and niobium reduces the hardness of the coating. The introduction of hafnium also increases, and niobium reduces, the value of the critical fracture load ...

Zr/Mg, Zr/Sr and Zr/Zn co-doped hydroxyapatites: Synthesis and characterization

Ceramics International, 2016
Abstract Zr/Mg, Zr/Sr and Zr/Zn co-doped hydroxyapatite samples, having high crystallinity, prepared by sol–gel synthesis were characterized via X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) spectroscopy. Based on the XRD results, it is shown that the kind
