About this book Introduction Ever since the first volume appeared in , this series has received good reviews in a variety of periodicals published in different corners of the world.
It would seem that the work has fulfilled its purpose as outlined in the Preface to Volume 1. The rapidly increasing interest in surface and colloid science by people engaged in industrial research and development, and in environmental, ecological, medical, pharmaceutical, and other areas, justifies the continuation of such an effort. This volume is the third with the present publisher, and is the best assurance of our mutual interest to proceed with this work. Some books in the series, as was the case with Volume 11, may appear under the editorship of other workers in the field.
For reasons of continuity, a sequential numbering system will be maintained. Electrostatic repulsion between particles depends on the value of zeta potential.
The higher the zeta potential, the stronger the repulsion, the more stable the system becomes. For instance, high zeta potential of the fat droplets in milk prevents them against coalescence. Reduction of it due to addition of acid would lead to cheese formation from the droplets coalescence.
This process leads to the build up of an electric surface charge. This surface charge creates an electrostatic field that then affects the ions in the bulk of the liquid. This electrostatic field, in combination with the thermal motion of the ions, creates a counter-charge, and thus screens the electric surface charge.
The net electric charge in this screening diffuse layer is equal in magnitude to the net surface charge, but has the opposite polarity. As a result the complete structure is electrically neutral. Distribution of the electric potential in the DL is shown on Figure below for positively charged surface.
Electric potential drops by approximately 2. It is approximately 1 nm at the ionic strength 0.

Interfacial Phenomena and Colloid Stability- Basic Principles deals with the fundamental aspects of interfacial phenomena, which form the basis of.
The Positron normally lives a virtual existence inside the proton in the atom's nucleus. We call the electric tension of the electron, "Negative" and the tension charge of the positron we call "Positive".
Unfortunately, we also talk about an atom's "Valance Possibilities" in terms of positive and negative energies. This is not correct and produces much confusion in the understanding of chemical bonds and Zeta Potential. What we call "Chemical Bonds" are actually a special Symbiotic Arrangement between atoms that are on a quest for "Dynamic Stability"!
Usually, all the atoms in the arrangement are electrically in balance. They both have an equal number of positrons and electrons. What aren't in balance are the atom's electron orbitals. The "Universal Atomic Template" has a definite preference for the order and way that electrons are put in orbit around the atom's nucleus. The atom's ultimate goal is to have two electrons, with complementary spins, in each orbital level, but the "Atomic Template" has different criteria for filling the atom's orbits.
The orbits are filled with respect to the amount of momentum that is required to keep the electrons in their different orbits.
