2. Tetrahydrocannabinol - Wikipedia

   en.wikipedia.org/wiki/Tetrahydrocannabinol

   It is the principal psychoactive constituent of cannabis and one of at least 113 total cannabinoids identified on the plant. Although the chemical formula for THC (C 21 H 30 O 2) describes multiple isomers, [10] the term THC usually refers to the delta-9-THC isomer with chemical name (−)-trans-Δ9-tetrahydrocannabinol.

3. Metal–organic framework - Wikipedia

   en.wikipedia.org/wiki/Metal–organic_framework

   MIL-101, a large-cavity MOF having the formula [Cr 3 F(H 2 O) 2 O(BDC) 3], is a cyanosilylation catalyst. [56] The coordinated water molecules in MIL-101 are easily removed to expose Cr(III) sites. As one might expect, given the greater Lewis acidity of Cr(III) vs. Cu(II), MIL-101 is much more active than HKUST-1 as a catalyst for the ...

4. Debye model - Wikipedia

   en.wikipedia.org/wiki/Debye_model

   The Debye model is a solid-state equivalent of Planck's law of black body radiation, which treats electromagnetic radiation as a photon gas confined in a vacuum space. Correspondingly, the Debye model treats atomic vibrations as phonons confined in the solid's volume. Most of the calculation steps are identical, as both are examples of a ...

5. Atom - Wikipedia

   en.wikipedia.org/wiki/Atom

   Electrons and a compact nucleus of protons and neutrons. Atoms are the basic particles of the chemical elements. An atom consists of a nucleus of protons and generally neutrons, surrounded by an electromagnetically bound swarm of electrons. The chemical elements are distinguished from each other by the number of protons that are in their atoms.

7. Cubic equation - Wikipedia

   en.wikipedia.org/wiki/Cubic_equation

   Here the function is and therefore the three real roots are 2, −1 and −4. In algebra, a cubic equation in one variable is an equation of the form in which a is not zero. The solutions of this equation are called roots of the cubic function defined by the left-hand side of the equation. If all of the coefficients a, b, c, and d of the cubic ...

8. Dark matter - Wikipedia

   en.wikipedia.org/wiki/Dark_matter

   The hypothesis of dark matter has an elaborate history. [18] [19] In the appendices of the book Baltimore lectures on molecular dynamics and the wave theory of light where the main text was based on a series of lectures given in 1884, [18] Lord Kelvin discussed the potential number of stars around the Sun from the observed velocity dispersion of the stars near the Sun, assuming that the Sun ...
