Quantum Numbers

It is said that the energy of an electron in an atom is quantized; that is, it can be equal only to certain specific values and can jump from one energy level to another but not transition smoothly or stay between these levels.

Cells Coordinate Growth and Proliferation

5.1K
Cell size is a significant factor impacting cellular design, function, and fitness. There exists some internal coordination by which cells double their masses before division, thus, achieving homeostasis. Coordination between cell growth and proliferation depends on the checkpoints in between cell cycle phases. Loss of coordination or failure in the checkpoint mechanism can drive the cell to uncontrolled growth and loss of cellular function. Like dividing cells that coordinate cellular growth,...

The Quantum-Mechanical Model of an Atom

59.0K
Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra.

Coordination Number and Geometry

19.1K
For transition metal complexes, the coordination number determines the geometry around the central metal ion. Table 1 compares coordination numbers to molecular geometry. The most common structures of the complexes in coordination compounds are octahedral, tetrahedral, and square planar.

Coordination Compounds and Nomenclature

In most main group element compounds, the valence electrons of the isolated atoms combine to form chemical bonds that satisfy the octet rule. For instance, the four valence electrons of carbon overlap with electrons from four hydrogen atoms to form CH4. The one valence electron leaves sodium and adds to the seven valence electrons of chlorine to form the ionic formula unit NaCl (Figure 1a). Transition metals do not normally bond in this fashion. They primarily form coordinate covalent bonds, a...

Lattice Centering and Coordination Number

11.7K
The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.

Background:

  • Conventional solvent-free nanofluids present challenges in preparation and performance tuning.
  • Molybdenum disulfide (MoS2) quantum dots (QDs) show potential as advanced lubricant additives.

  • To evaluate the tribological performance of MoNFs as lubricants and in engine oil formulations.

Main Methods:

  • One-pot coordination-confined growth approach for synthesizing MoS2 QDs.
  • Homogeneous dispersion of cyan-fluorescent MoS2 QDs in an ionic liquid matrix.
  • Tribological testing of MoNFs as lubricants and blended in commercial engine oil.
  • Characterization of worn surfaces using advanced analytical techniques.

Main Results:

  • Synthesized MoNFs with tunable viscosity and desirable shear-thinning behavior.
  • Optimal MoNF formulation (3MoNFs) reduced wear volume by 73.8% compared to the base fluid.
