Neutral matter

In order to study the effects of different TBF on neutron star structure, we have to calculate the composition and the EOS of cold, catalyzed matter. We require that the neutron star contains charge neutral matter consisting of neutrons, protons, and leptons (e, p ) in beta equilibrium. Using the various TBF discussed above, we compute the proton fraction and the EOS for charge neutral and beta-stable matter in the following standard way [23, 24] The Brueckner calculation yields the energy density of lepton/baryon matter as a function of the different partial densities,... 

Figure 2. Phase diagram in the /u — (iq plane for T = /U3 = /us = 0. The various phases separated by the solid lines are characterized by different non-vanishing diquark gaps Ai as indicated in the figure. In the non-superconducting phase quarks are present only above the dashed line. The + and signs indicate the sign of the electric charge density in the corresponding region. The dotted line corresponds to electrically neutral matter in the CFL phase.

Rosin, a brittle solid, mp 80 °C, is obtained from the gum of trees and tree stumps as a residue after steam distillation of the turpentine. It is made of 90% resin acids and 10% neutral matter. Resin acids are tricyclic monocarboxylic acids of formula C20H30O2. The common isomer is 1-abietic acid. About 38% of rosin is used as paper size (its sodium salt), in synthetic rubber as an emulsifier in polymerization (13%), in adhesives (12%), coatings (8%), and inks (8%). 

Collision-induced absorption is the principal spectroscopy of dense, cool (i.e., basically neutral) matter, especially of matter composed of non-polar atoms and molecules. 

Dielectrophoresis is the translational motion of neutral matter owing to polarization effects in a non-uniform electric field. Depending on matter or electric parameters, different particle populations can exhibit different behavior, e.g. following attractive or repulsive forces. DEP can be used for mixing of charged or polarizable particles by electrokinetic forces [48], In particular, dielectric particles are mixed by dielectrophoretic forces induced by AC electric fields, which are periodically switched on and off. 

Charge is a quantized property of non-neutral matter. Charge can be positive or negative. Like charges repel and unlike charges attract. Electrical...

Rosin, the other major naval stores product, is a brittle solid that softens at 80°C. Chemically it is composed of about 90 percent resin acids and 10 percent neutral matter. The resin acids are mainly /-abietic acid and its isomers, C2oH3002. These are tricyclic mono-carboxylic acids and are diterpenes. 

An ion may be imagined as a neutral matter that carries a charge. Of course, the charge has also some matter. So we will be more precise in the next sentence. An electrode serves as a separator for ions and the charge. It is permeable to the charge, but is not permeable to the neutral part of the ion. When an ion moves to the electrode, the charge is stripped off from the ion and the ion is discharged. Think about the similarity to the semipermeable membrane. 

The field of dielectrophoresis is relatively recent. Herbert Pohl did dielectrophoretic research in the 1950s although this area did not gain wide visibility until his groundbreaking book Dielectrophoresis The behavior of neutral matter in nonuniform electric fields was published in 1978 [1]. In this book, the two main components of the electric field in alternating current (AC) dielectrophoresis were extensively discussed, namely, (i) a spatially nonuniform electric field and (ii) an alternating current electric field, both of which contribute to the nonlinear DEP force. Within the last 10 years. 

The dipolar correlation is the principal interaction in the classical theory of dielectric properties of matter. In fact, neutral matter is equivalent to an assemblage of electric dipoles as far as its electrical properties are concerned [4], and various approximations have been proposed to deal with the dipole interaction [5]. However, behaviour of dipolar substances at the temperature at which the thermal energy is comparable with the dipole interaction is not understood well. It is therefore desirable to study properties of substances which undergo phase transitions due to the dipole interaction.
