Approach to determine nodal surfaces of some s-electron systems.

The paper is devoted to the study of the nodal surfaces of the wave functions for fermion systems. Using the quantum Monte Carlo method, implicit equations of nodal surfaces for some s-electron systems containing two-five electrons are numerically obtained. The obtained results are in agreement with the provisions of other researchers.

Dataset illustrating the construction of dislocations and running dislocation dynamics using the periodic array of dislocation quadrupoles in FCC Al.

The data illustrates the process of creation of dislocation quadrupoles in FCC Al. The density of dislocations in our data is 3.8 × 10 m which is the lowest published to date and is comparable to the density of dislocations in real crystals.

Role of metal-binding domains of the copper pump from Archaeoglobus fulgidus.

CopA from the extreme thermophile Archaeoglobus fulgidus is a P-type ATPase that transports Cu(+) and Ag(+) and has individual metal-binding domains (MBDs) at both N- and C-termini. We expressed and purified full-length CopA as well as constructs with MBDs deleted either individually or collectively. Cu(+) and Ag(+)-dependent ATPase assays showed that full-length CopA had submicromolar affinity for both ions, but was inhibited by concentrations above 1muM.
