X-ray measured metallicities of the intra-cluster medium: a good measure for the metal mass? [PDF]
, 2007 Aims. We investigate whether X-ray observations map heavy elements in the Intra-Cluster Medium (ICM) well and whether the X-ray observations yield good estimates for the metal mass, with respect to predictions on transport mech- anisms of heavy elements from galaxies into the ICM. We further test the accuracy of simulated metallicity maps. Methods.

Metal Preferences and Metallation [PDF]
Journal of Biological Chemistry, 2014 The metal binding preferences of most metalloproteins do not match their metal requirements. Thus, metallation of an estimated 30% of metalloenzymes is aided by metal delivery systems, with ∼ 25% acquiring preassembled metal cofactors. The remaining ∼ 70% are presumed to compete for metals from buffered metal pools.

Time-reversal symmetric topological metal [PDF]
Phys. Rev. B 104, 165422 (2021), 2021 Topological metals possess gapless band structures accompanied with nontrivial edge states. Topological metals are created from the topological insulators by adjusting the magnetic flux. Here we propose the time-reversal symmetry protected topological metal without employing the magnetic flux.

Spatial metallicity variations of mono-temperature stellar populations revealed by early-type stars in LAMOST [PDF]
A&A 674, A129 (2023), 2023 We investigate the radial metallicity gradients and azimuthal metallicity distributions on the Galactocentric $X$--$Y$ plane using mono-temperature stellar populations selected from LAMOST MRS young stellar sample. The estimated radial metallicity gradient ranges from $-$0.015\,dex/kpc to $-$0.07\,dex/kpc, which decreases as effective temperature ...

Reproduction Sensitivity of Five Daphnia Species to Nickel
Journal of Water and Environment Technology, 2020 In Japan, data on the reproduction sensitivity of Daphnia magna, which is a widely used organism in laboratory toxicity tests, to nickel are key to determination of water quality target values for nickel, which are used to set values for the ...

Is the atomic metal vapor a dielectric state? [PDF]
Physica Scripta, 2021, 2020 We propose a simple method for calculating the metal vapor conductivity at the critical point and near-critical isotherms. This method's base is the hypothesis of an electron jellium's existence as an origin of the conduction band in metal vapor's gaseous phase. Satisfactory agreement with the experimental data for alkali metals (Cs, Rb) concludes that

Tailored ZnS/Ag/TiOx transparent and conductive electrode for organic solar cells
EPJ Photovoltaics, 2019 Organic photovoltaic cells (OPVCs) attract high interest for solar energy harvesting. They are based on organic thin films sandwiched between two electrodes, one of them being transparent and conductive.
