Previous analyses of single diatom chloroplast protein-encoded genes recovered results highly incongruent with both traditional phylogenies and phylogenies derived from the nuclear encoded small subunit (SSU) gene. Our analysis here of six individual chloroplast genes (atpB, psaA, psaB, psbA, psbC a

Using first-principles density functional theory calculations, we investigate the geometries, electronic structures, and thermodynamic stabilities of substitutionally doped phosphorene sheets with group III, IV, V, and VI elements. We find that the electronic properties of phosphorene are drasticall
Effect of Solute Silicon on the Lattice Parameter of Ferrite in Ductile Irons
Huyan Fei,Larker Richard,Rubin Per,Hedström Peter
ISIJ International 54(1), 248-250, 2014
… Since substitutional solution by silicon contracts the ferrite lattice while the interstitial solution by carbon expands the lattice, the Si contraction coefficient found will have a significant effect on subsequent evaluation of the carbon content in austempered Si-alloyed ductile irons and steels. …
… By using the ab initio density functional theory method and the non-equilibrium Green's function approach, electronic transfer properties in armchair shaped edges graphene nanoribbons (AGNRs) doped with one substitutional boron or nitrogen impurity are numerically investigated. …
