The alkaline earth metal magnesium (atomic number 12), with its 12 electrons in a [Ne]3s2 configuration, is analogous to its family member beryllium, [He]2s2. Both atoms have a filled s subshell outside their filled inner shells. Aluminum (atomic number 13), with 13 elect...

Currently, single-atom catalysts (SACs) have intrigued new interests in heterogenous electrocatalysis because of their outstanding activity and maximum atom utilization efficiency42,43. The impressive catalytic activity of SACs greatly results from the distinctive electronic structure of single metal atoms an...
Projects about magnesium-based doped of transition metal have constantly attracted much attention in cluster science, while the research of Co, Fe, Ni doped Mid-Sized Mg-16 clusters has not been reported. Here, the geometric construction and electronic properties of neutral and negative Mg16X (X...
The electronic properties of heterostructures containing (Cd,Mn)Te quantum wells are probed by soft x-ray spectroscopies. We provide experimental evidence that Mn ions are in theMn2+(3d5)electronic configuration, and rule out the possibility that charge transfer and crystal field effects can reduce...
High-pressure transitions are thought to modify hydrogen molecules to a molecular metallic solid and finally to an atomic metal1, which is predicted to have exotic physical properties and the topology of a two-component (electron and proton) superconducting superfluid condensate2,3. Therefore, underst...

The geometric configuration of type I is found to be the most stable state for both of these alloys as delineated in Fig. 2 through three different types. The structure is optimized in three phases, i.e., spin-polarized (Ferromagnetic FM), non-spin-polarized (non-magnetic NM) and anti-...
Plots of the potential energy and the dipole moment of four low-lying electronic states of the MgN molecule have been calculated by the self-consistent-field and configuration-interaction methods in the effective-core-potential approximation. The ground state of the molecule is not bound and has ...
