From its electronic configuration, predict which of the first 10 elements would be most similar in chemical behavior to the as yet undiscovered element 168. From its electronic configuration, predict which of the first 10 elements would be ...
All samples were vortexed by centrifuge rotation for 1 min, ultrasonicated for 15 min and then centrifuged for 10 min to extracts the PAHs. The upper liquid was transferred into a new clean vial with the activated copper for desulphurization. Then residual sediments were reextracted twice by ...

Synthesis by self-assembly and structural characterization of a new co-crystal system {[Cu(NO3)2(H2O)2]L1(NO3)2} (L1 = 1,1′-dibenzyl-3,3′-butyl-diimidazolium-2,2′-diylidene) from copper nitrate and a carbene precursor Cent. Eur. J. Chem., 6 (2008), pp. 505-508, 10.2478/s1...
Canadian pennies made before 1996 consists of 98% copper. Copper is made up of two isotopes, Cu-63 (63.9296 amu) and Cu-65 (64.9278). Given coppers atomic weight of 63.546, what is the percentage abun For Effective Nuclear Charge, I'm confused about why the electrons woul...
This combined CALYPSO/DFT computational approach has been previously used to search for low-lying palladium clusters, copper clusters, ruthenium doped germanium clusters et al.37,38,39,40. Based on the lowest energy structure, the electronic and magnetic properties are investigated in detail as the...
Materials for energy-related applications, which are crucial for a sustainable energy economy, rely on combining materials that form complex heterogenous interfaces. Simultaneously, progress in computational materials science in describing complex interf

7. The donation of an electron by the Cu5 cluster successfully explains the absorption spectroscopy measurements at the K-edge of copper presented in the upper panel of Fig. 8. In particular, a split of the main absorption line is present in the spectra (denoted as A and B). This ...
However, these studies typically consider experimental geometry, performing only single-point energy calculations to predict the magnetic nature of crystal structures [10], [12], [13], [14], [15]. Contrastingly, validating the ability of a methodology to predict a property involves optimizing the...
