Synergistic Effects of Surfactants

Observed when surfactants having relatively similar structure or ionic property are mixed
Resulted in the formation of liquid crystal structures or complexes at the interface by intermolecular interactions between surfactants
Examples
Anionic and nonionic in synthetic latex emulsion polymerisation,
Mixture of a dispersant ....etc

generation of electricity from speed breaker using piezoelectric crystals

Energy is the primary need for survival of all organisms in the universe. Everything what happens in the surrounding is the expression of flow of energy in one of the forms. But in this fast moving world, population is increasing day by day and the conventional energy sources are lessening. The extensive usage of energy has resulted in an energy crisis over the few years. Therefore to overcome this problem we need to implement the techniques of optimal utilization of con ....etc

Organic material that has semiconductor properties. Semiconductivity is exhibited by single molecules, short chain (oligomers) and organic polymers. Semiconducting small molecules (aromatic hydrocarbons) include the polycyclic aromatic compounds pentacene, anthracene,and The environment of surface electrons at 'solid-to-liquid' interfaces is somewhat extreme, subjected to intense local electric fields or harsh chemical pressures that high-density ionic charge or polarization of mobile molecules create. In this proceedings, we argue functions of ....etc

Hardware for image processing - Basics Eye Human vision sensor

History

Photography appeared in XIX century.
Ideas for developing fax machines and usage of telegraphic lines for
image submission was born during the World War I.
The idea about TV development was born around 1930.
The key event in digital image processing was development of the
first electronic computing machines. These machines enabled simple
and fast image processing.
The second important event was astronomical exploration ....etc

A Theory of Anharmonic Lattice Statics for Analysis of Defective Crystals

In this topic we present a general theory of anharmonic lattice statics for analysis of defective complex lattices. This theory differs from the classical treatments of lattice statics in that it does not rely on knowledge of force constants for a limited number of nearest neighbor interactions. Instead, the only thing needed as input is an interatomic potential that models the interaction of atoms this theory takes into account the fact that close to defects force con ....etc
