  2. Covalent organic framework - Wikipedia

    en.wikipedia.org/wiki/Covalent_organic_framework

    While at University of Michigan, Omar M. Yaghi (currently at UCBerkeley) and Adrien P Cote published the first paper of COFs in 2005, reporting a series of 2D COFs. [5] They reported the design and successful synthesis of COFs by condensation reactions of phenyl diboronic acid (C 6 H 4 [B(OH) 2] 2) and hexahydroxytriphenylene (C 18 H 6 (OH) 6).

    en.wikipedia.org/wiki/Network_covalent_bonding

    A network solid or covalent network solid (also called atomic crystalline solids or giant covalent structures) [1] [2] is a chemical compound (or element) in which the atoms are bonded by covalent bonds in a continuous network extending throughout the material.

    en.wikipedia.org/wiki/Organic_compound

    Methane (CH 4) is among the simplest organic compounds.. Some chemical authorities define an organic compound as a chemical compound that contains a carbon–hydrogen or carbon–carbon bond; others consider an organic compound to be any chemical compound that contains carbon.

  8. Composite fermion - Wikipedia

    en.wikipedia.org/wiki/Composite_fermion

    These are Shubnikov–de Haas oscillations of composite fermions. [13] [14] These oscillations arise from the quantization of the semiclassical cyclotron orbits of composite fermions into composite fermion Landau levels. From the analysis of the Shubnikov–de Haas experiments, one can deduce the effective mass and the quantum lifetime of ...
