Binary Fission01:26

Binary Fission

3.0K
Binary fission is the primary mode of asexual reproduction in prokaryotes, such as bacteria. It results in the production of two genetically identical daughter cells. This highly efficient process ensures the rapid propagation of bacterial populations under favorable conditions and involves coordinated cellular and molecular events.DNA Replication and SeparationThe process begins with the replication of the bacterial chromosome. The circular DNA molecule unwinds at a specific origin of...

Binary Fission

63.5K
Fission is the division of a single entity into two or more parts, which regenerate into separate entities that resemble the original. Organisms in the Archaea and Bacteria domains reproduce using binary fission, in which a parent cell splits into two parts that can each grow to the size of the original parent cell. This asexual method of reproduction produces cells that are all genetically identical.

The Looking Glass Self01:28

The Looking Glass Self

358
The concept of the looking-glass self describes how an individual's self-concept is shaped by their perception of how others see them. This psychological theory, first introduced by sociologist Charles Horton Cooley in 1902, posits that self-identity emerges in a social context and is influenced by the judgments—real or imagined—of others.Research suggests that individuals frequently overestimate how positively others perceive them. This is particularly evident in physical...

Chemical Formulas

61.2K
A chemical formula presents information about the proportions of atoms constituting a particular chemical compound or molecule, mainly using symbols of elements and numbers. At times other symbols, such as dashes, parentheses, brackets, commas, plus, and minus signs, are also used. A chemical formula can be one of three types – molecular, empirical, and structural.

Chemical Equations03:10

Chemical Equations

81.3K
Chemical equations represent the identities and relative quantities of substances involved in a chemical reaction. The substances undergoing reaction are called reactants, and their formulas are placed on the left side of the equation. The substances generated by the reaction are called products, and their formulas are placed on the right side of the equation. Plus signs (+) separate individual reactant and product formulas, and an arrow (→) separates the reactant and product (left and right)...

Chemical Reactions

95.7K
A chemical reaction is a process by which the bonds in the atoms of substances are rearranged to generate new substances. Matter cannot be created or destroyed in a chemical reaction—the same type and number of atoms that make up the reactants are still present in the products. Merely, the rearrangement of chemical bonds produces new compounds.

Area of Science:

  • Materials Science
  • Solid State Chemistry
  • Spectroscopy

Background:

  • Binary chalcogenide glasses, specifically sulfur-selenium (S-Se) systems, exhibit complex structural behaviors.
  • Understanding the relationship between composition, structure, and properties is crucial for material design.

Purpose of the Study:

  • To investigate the compositional evolution of structure and chemical order in SxSe100-x glasses.
  • To correlate structural changes with macroscopic properties such as glass transition temperature (Tg) and molar volume.

Main Methods:

  • High-resolution 2D 77Se isotropic-anisotropic correlation Nuclear Magnetic Resonance (NMR) spectroscopy.
  • Raman spectroscopy.

Main Results:

  • S-Se glasses comprise polymeric [Se,S]n chains and eight-membered SeyS8-y rings.
  • Increasing sulfur content shifts selenium atoms from chains to rings, altering ring and chain compositions.
  • -Se-Se- bonding is favored, especially with multiple selenium atoms in rings and chains.

Conclusions:

  • The structure of S-Se glasses evolves linearly with composition, driven by the formation of chains and rings.
  • This linear structural evolution correlates with a linear decrease in glass transition temperature and molar volume as sulfur concentration increases.
