Robust photocatalytic reduction of Cr(VI) on UiO-66-NH2(Zr/Hf) metal-organic framework membrane under sunlight irradiation

Chemical Engineering Journal, 2019
The removal of toxic hexavalent chromium (Cr(VI)) ions from surface and ground water is highly demanded. While photocatalytic reduction of Cr(VI) to Cr(III) by traditional powder photocatalysts is a promising method, the difficult in the separation of ...

An Electrochemical Biosensor Designed by Using Zr-Based Metal-Organic Frameworks for the Detection of Glioblastoma-Derived Exosomes with Practical Application.

Analytical Chemistry, 2020
Glioblastoma (GBM) is one of the most fatal tumors in the brain, and its early diagnosis remains technically challenging due to the complex repertoires of oncogenic alterations and blood-brain barrier (BBB).

Laser-based directed energy deposition of novel Sc/Zr-modified Al-Mg alloys: columnar-to-equiaxed transition and aging hardening behavior

Journal of Materials Science & Technology, 2021
The control of grain morphology is important in laser additive manufacturing (LAM), as grain morphology further affects the hot cracking resistance, anisotropy, and strength–ductility synergy of materials. To develop a solidification-control solution and

Microstructures and tensile properties of a selective laser melted Al–Zn–Mg–Cu (Al7075) alloy by Si and Zr microalloying

Materials Science & Engineering: A, 2020
The application of conventional Al–Zn–Mg–Cu alloys for selective laser melting (SLM) of additive manufacturing is hindered by hot cracking during the SLM process. In the present work, a novel Si- and Zr-modified Al–Zn–Mg–Cu (Al7075) prealloyed powder was

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.

Laser powder bed fusion of high-strength Sc/Zr-modified Al–Mg alloy: phase selection, microstructural/mechanical heterogeneity, and tensile deformation behavior

, 2021
Laser powder bed fusion (L-PBF) of Sc/Zr-modified Al-based alloys has recently become a promising method for developing a new generation of high-performance Al alloys. To clarify the modification roles of Sc/Zr elements, an Al–4.66Mg–0.48Mn–0.72Sc–0.33Zr

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 ...

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.

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.
