Human manganese superoxide dismutase (MnSOD) is a CPET-based oxidoreductase found in the mitochondrial matrix that reduces ROS levels by eliminating O2•−with the unpaired electrons of the active site metal. The Mn ion is coordinated to inner-sphere residues His26, His74, His163, Asp159, ...
The mean depth probed (for which the total path length equals the inelastic mean free path) is either 5 or 15 nm in our experiment, depending on the geometry used. Before annealing, the elastic peak from O is thus mainly due to electrons scattered from (16)O in the outer layer, while...
The structure obtained by X-ray diffraction studies of compound 1ClO4 shows that the Ag(III) centre is tet- racoordinated and exhibits a nearly square planar geometry, in which the aryl moiety and three amine N atoms are coplanar with the silver centre (Fig. 2b). The Ag–C bond length...
During the last decade, modern micro-electro-mechanical systems (MEMS) technology has been used to create cells that can act as catalytic nanoreactors and fit into the sample holders of transmission electron microscopes. These nanoreactors can maintain atmospheric or higher pressures inside the cells a...
When the sample is bombarded by incoming Ga ions, surface materials are sputtered away in the forms of atoms, ions, and clusters from their original positions and flying around in a vacuum. Depending on the ion beam intensity and sample geometry, a certain amount of sputtered materials would ...
To do that, the 3D topology of the EPLF calculated with quantum Monte Carlo (at both variational and fixed-node-diffusion Monte Carlo levels) using Hartree−Fock, multiconfigurational CASSCF, and explicitly correlated trial wave functions is analyzed. At the O4 equilibrium geometry the EPLF ...
The process involves fabrication of two metal layers defined by electron-beam lithography (EBL, Vistec, Jena, Germany) with ALD dielectric in between. The general approach for fabrication of SETs in the cross-tie geometry is outlined below, while more fabrication details are given within the ...
Vector diagram showing collision geometry for the (e,2e) +symmetric non-coplanar scattering kinematics. The experimental parameters are: 0, = O2 = 4S0, = 180°, 4 1 ~= = variable. The expression in eq. [2] follows from energy conserva- tion, [3] Eo = E l + E2 + E3 + Eb ...
The geometry of the cyanide ligand appears to be maintained via hydrogen bonding interactions with the distal histidine Nϵ and with Waters 843 and 845 in the distal cavity. The low pH (pH 4.0) MPO crystal structure (R = 0.204, Rfree = 0.248) suggests that a putative peroxide (H ...
