Introductory Solid State Physics (Second Edition)

Assuming an simple wisdom of quantum and statistical physics, this ebook presents a entire advisor to central actual homes of condensed topic, in addition to the underlying idea invaluable for a formal realizing in their origins. the subject material covers the valuable positive factors of condensed subject physics, yet with specific accessory at the homes of steel alloys.

Theory of High Temperature Superconductivity: A Conventional Approach

Drawing from the extensive spectrum of phenomena, defined in additional than 100,000 articles on high-Tc superconductivity, during this e-book, the authors research these uncomplicated homes for which figuring out might be accomplished in the framework of conventional equipment of theoretical physics. this can be the case of the overdoped cuprates for which the "Bardeen software" has been learned: we all know their digital spectrum, we will be able to calculate their simple thermodynamic and electrodynamic homes, and are expecting new phenomena.

Nanotubes and Nanosheets: Functionalization and Applications of Boron Nitride and Other Nanomaterials

Nanotubes and nanosheets are low-dimensional nanomaterials with exact homes that may be exploited for varied purposes. This ebook bargains an entire evaluation in their constitution, houses, improvement, modeling techniques, and sensible use. It focuses cognizance on boron nitride (BN) nanotubes, that have had significant curiosity given their targeted high-temperature homes, in addition to graphene nanosheets, BN nanosheets, and steel oxide nanosheets.

Example text

Aggregation of particles and droplets (referred to as heteroflocculation) must be prevented, otherwise the formulation loses its physical stability on storage. The stability/instability of any agrochemical dispersion is determined by the balance of three main forces: (1) van der Waals attraction that is universal for all disperse systems, and it results mainly from the London dispersion forces between the particles or droplets. (2) Double layer repulsion that arises when using ionic surfactants or polyelectrolytes.

In most cases, there is a correlation between the critical flocculation point and the y condition of the medium. Good correlation is found in many cases between the critical flocculation temperature (CFT) and y-temperature of the polymer in solution (with block and graft copolymers one should consider the y-temperature of the stabilizing chains A) (Tadros et al. 1981; Napper 1981). Good correlation is also found between the critical volume fraction (CFV) of a non-solvent for the polymer chains and their y-point under these conditions.

It should be mentioned at this stage that for such a polymer to adsorb, the reduction in entropy of the chain as it approaches the interface must be compensated by an energy of adsorption between the segments and the surface. In other words, the chain segments must have a minimum adsorption energy, ws, otherwise no adsorption occurs. With polymers that are highly A A 26 water soluble, such as poly(ethylene oxide) (PEO), the interaction energy with the surface may be too small for adsorption to occur, and if this takes place, the whole molecule may not be strongly adsorbed to the surface.
