  2. Transport phenomena - Wikipedia

    en.wikipedia.org/wiki/Transport_phenomena

    The constitutive equations describe how the quantity in question responds to various stimuli via transport. Prominent examples include Fourier's law of heat conduction and the Navier–Stokes equations , which describe, respectively, the response of heat flux to temperature gradients and the relationship between fluid flux and the forces ...

    en.wikipedia.org/wiki/Bell–Evans–Polanyi...

    In physical chemistry, the Evans–Polanyi principle (also referred to as the Bell–Evans–Polanyi principle, Brønsted–Evans–Polanyi principle, or Evans–Polanyi–Semenov principle) observes that the difference in activation energy between two reactions of the same family is proportional to the difference of their enthalpy of reaction.

  4. Reversal potential - Wikipedia

    en.wikipedia.org/wiki/Reversal_potential

    An important concept related to the equilibrium potential is the driving force. Driving force is simply defined as the difference between the actual membrane potential and an ion's equilibrium potential V m − E i {\displaystyle V_{\mathrm {m} }-E_{\mathrm {i} }\ } where E i {\displaystyle E_{\mathrm {i} }\ } refers to the equilibrium ...

    en.wikipedia.org/wiki/Langevin_dynamics

    For a system of particles with masses , with coordinates = that constitute a time-dependent random variable, the resulting Langevin equation is [2] [3] ¨ = ˙ + (), where () is the particle interaction potential; is the gradient operator such that () is the force calculated from the particle interaction potentials; the dot is a time derivative ...

  6. Pinacol rearrangement - Wikipedia

    en.wikipedia.org/wiki/Pinacol_rearrangement

    The driving force for this rearrangement step is believed to be the relative stability of the resultant oxonium ion. Although the initial carbocation is already tertiary, the oxygen can stabilize the positive charge much more favorably due to the complete octet configuration at all centers.

  7. Molecular biophysics - Wikipedia

    en.wikipedia.org/wiki/Molecular_biophysics

    This discipline covers topics such as the measurement of molecular forces, molecular associations, allosteric interactions, Brownian motion, and cable theory. [2] Additional areas of study can be found on Outline of Biophysics. The discipline has required development of specialized equipment and procedures capable of imaging and manipulating ...

  8. Mass spectral interpretation - Wikipedia

    en.wikipedia.org/wiki/Mass_spectral_interpretation

    Identification of the molecular ion can be difficult. Examining organic compounds, the relative intensity of the molecular ion peak diminishes with branching and with increasing mass in a homologous series. In the spectrum for toluene for example, the molecular ion peak is located at 92 m/z corresponding to its molecular mass. Molecular ion ...

  9. Molecular mechanics - Wikipedia

    en.wikipedia.org/wiki/Molecular_mechanics

    A force field is used to minimize the bond stretching energy of this ethane molecule. Molecular mechanics uses classical mechanics to model molecular systems. The Born–Oppenheimer approximation is assumed valid and the potential energy of all systems is calculated as a function of the nuclear coordinates using force fields. Molecular ...
