|These are a thermodynamically stable, isotropic liquid mixture of oil, water and surfactant. Generally the aqueous mixture consists of salt or other substances and the oil part contains hydrocarbons or olefins. Microemulsions have several industrial applications among which the most important is its use in the synthesis of polymers.
High-impact journals are those considered to be highly influential in their respective fields. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
