Molecular engineering is an emerging field of study concerned with the design and testing of molecular properties, comportment and interactions in order to assemble better materials, systems, and processes for categorical functions. Molecular engineering is an emerging field of study concerned with the design and testing of molecular properties, department and interactions in order to assemble better materials, systems, and processes for categorical functions. Bio molecular engineers coalesce cognizance in molecular biology, biophysical chemistry and chemical engineering to develop everything from pharmaceutical drugs to foods. Numerous industries employ bio molecular engineers, including the military, Coalesced States regime, petroleum and manufacturing. Biochemical engineers cumulate erudition of biology, chemistry and engineering to engender products from raw materials and develop the processes for achieving this. They additionally find solutions to quandaries which occur when materials and processes interact with the environment. There are now six major branches of engineering: Mechanical, Chemical, Civil, Electrical, Management, and Geotechnical, and literally hundreds of different subcategories of engineering under each branch. The mundane consensus is that the hardest engineering degrees are mechanical and aerospace with chemical, electrical, and computer engineering in second, and civil and environmental in last. The citations are paramount for a journal to get impact factor. Impact factor is a quantification reflecting the average number of citations to recent articles published in the journal. The international journals are among the best open access journals in the world, set out to publish the most comprehensive, pertinent and reliable information predicated on the current research and development on a variety of subjects. To increment the overtness and facilitate of avail of open access scientific and scholarly journals top online publishing journals are indexed in different indexing and archiving accommodations. Indexing provides facile access of the article online. The top online publishing journals publish articles which are cited as references by many authors in their work this information can be published in our peer reviewed journal with impact factors and are calculated utilizing citations not only from research articles but additionally review articles. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and endeavor to increment their number expeditiously. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and endeavor to increment their number expeditiously. Impact factor plays a major role for the particular journal. Molecular engineering is peer reviewed journals works to publish most reliable and consummate source of information regarding advance revelations and development in the path of molecular engineering..
