Summary
This study reveals bilayer phosphorene
Area of Science:
- Condensed Matter Physics
- Materials Science
- Quantum Optics
Background:

Main Methods:
- Generalized tight-binding model.
- Gradient approximation for electronic structure calculations.
- Analysis of inter-Landau-level transitions.
Main Results:
- Optical absorption is sensitive to polarization and sublattice symmetries.
- Electric fields significantly alter selection rules and spectral features.
- Unusual magneto-optical phenomena emerge beyond a critical electric field due to distinct Landau level subgroups.
Conclusions:

Many covalent molecules have central atoms that do not have eight electrons in their Lewis structures. These molecules fall into three categories:

01:34Woodward–Hoffmann Selection Rules and Microscopic Reversibility
4.0K
Electrocyclic reactions, cycloadditions, and sigmatropic rearrangements are concerted pericyclic reactions that proceed via a cyclic transition state. These reactions are stereospecific and regioselective. The stereochemistry of the products depends on the symmetry characteristics of the interacting orbitals and the reaction conditions. Accordingly, pericyclic reactions are classified as either symmetry-allowed or symmetry-forbidden. Woodward and Hoffmann presented the selection criteria for...

01:21The Phosphorus Cycle
44.0K
Unlike carbon, water, and nitrogen, phosphorus is not present in the atmosphere as a gas. Instead, most phosphorus in the ecosystem exists as compounds, such as phosphate ions (PO43-), found in soil, water, sediment and rocks. Phosphorus is often a limiting nutrient (i.e., in short supply). Consequently, phosphorus is added to most agricultural fertilizers, which can cause environmental problems related to runoff in aquatic ecosystems.

02:36Lewis Symbols and the Octet Rule
81.1K
Chemical bonds are complex interactions between two or more atoms or ions, which reduce the potential energy of the molecule. Gilbert N. Lewis developed a model called the Lewis model that simplified the depiction of chemical bond formation and provided straightforward explanations for the chemical bonds seen in most common compounds.

03:02The Aufbau Principle and Hund's Rule
73.0K
To determine the electron configuration for any particular atom, we can build the structures in the order of atomic numbers. Beginning with hydrogen, and continuing across the periods of the periodic table, we add one proton at a time to the nucleus and one electron to the proper subshell until we have described the electron configurations of all the elements. This procedure is called the aufbau principle, from the German word aufbau (“to build up”). Each added electron occupies the...

2.6K
Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s.
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.
