Vesicular Tubular Clusters01:45

Vesicular Tubular Clusters

After budding out from the ER membrane, some COPII vesicles lose their coat and fuse with one another to form larger vesicles and interconnected tubules called vesicular tubular clusters or VTCs. These clusters constitute a compartment at the ER-Golgi interface known as ERGIC (Endoplasmic Reticulum Golgi Intermediate Compartment). The ERGIC is a mobile membrane-bound cargo transport system that sorts proteins secreted from ER and delivers them to the Golgi.
With the help of motor proteins such...
Complexation Equilibria: Factors Influencing Stability of Complexes01:09

Complexation Equilibria: Factors Influencing Stability of Complexes

In complexation reactions, metal cations are the electron pair acceptors, and the ligands are the electron pair donors. The stability of the metal complexes depends primarily on the complexing ability of the central metal ion and the nature of the ligands. Generally, the complexing ability of the metal ion depends on the size and charge of the ion. As the metal ion size increases, the stability of the metal complexes decreases, provided that the valency of the metal ion and the ligands remain...
Colloidal precipitates01:09

Colloidal precipitates

The high insolubility of some precipitates can result in an unfavorable relative supersaturation. This can lead to colloidal particles with a large surface-to-mass ratio, where adsorption is promoted. For instance, in the precipitation of silver chloride, silver ions are adsorbed on the surface of the colloidal particles, forming a primary layer. This layer attracts ions of opposite charge (such as nitrate ions), forming a diffuse secondary layer of adsorbed ions. This electric double layer...
Formation of Complex Ions03:45

Formation of Complex Ions

A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

Area of Science:

  • Computational Chemistry
  • Materials Science
  • Quantum Chemistry

Background:

  • Silicon clusters (Si(n)) exhibit rich structural diversity, often forming cage-like structures.
  • Endohedral metallofullerenes involve encapsulating atoms within fullerene cages, influencing stability and properties.
  • Understanding doping effects in silicon nanostructures is crucial for developing new materials.

Purpose of the Study:

  • To investigate the structural and electronic properties of (Be, B, C)@Si(n)((0,1,2+)) clusters (n=6-10).
  • To explore the stabilization mechanisms of encapsulated atoms within silicon cages.
  • To compare the effects of Be, B, and C doping on Si(n) cluster stability.

Main Methods:

  • Density Functional Theory (DFT) calculations were employed.
  • Structural optimizations were performed to identify stable isomers.
  • Analysis of bonding using the Localized Orbital Locator (LOL) was utilized.

Main Results:

  • Multiple symmetric structures (rings, cages, open) were observed for the doped clusters.
  • Unusual bonding mechanisms were found, with no electron transfer for Be and no inversion for B and C compared to typical metallofullerenes.
  • The Si(8) cage showed enhanced stability with boron encapsulation over beryllium due to optimal size and bonding.

Conclusions:

  • Multicenter bonding is key to stabilizing small silicon cages.
  • Boron doping provides the best balance of size, electronegativity, and delocalized bonding for Si(n) stabilization.
  • These findings offer insights into designing novel doped silicon nanostructures.
