Ceramics can be classified as inorganic non-metallic solid made up of either metal or non-metal compounds that are shaped by subjecting them to heat at high temperatures. Advanced ceramic materials were used in day to day life example fridge magnets. They play a major role in modern medicine where they are used as dental implants and bone substitutes in orthopaedic operations. Ceramic artifacts plays an important role in archaeology for understanding technology, behaviour of the people and their culture in the past.
Ceramic materials are brittle, hard, and strong in compression, weak in shearing and tension. They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments.
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.
