*The Impact Factor provides an indication of the average number of citations per paper. Furthermore, this metric is of interest to the pharmaceutical industry where development of carbon skeletons is key to their work. Abstract. Green chemistry metrics are metrics that measure aspects of a chemical process relating to the principles of green chemistry. For example, when a highly pyrophoric reagent is replaced by a benign one, a numerical value is difficult to assign but the improvement is obvious, if all other factors are similar.. the use of chemistry for source reduction or pollution prevention, the highest tier of the risk management hierarchy as described in the Pollution Prevention Act of 1990. A responsible user is also required to achieve the goals of green chemistry. al., Green Chem., 2016, 18, 288-296. This definition leaves the metric open to criticism, as nothing is absolutely benign (which is a subjective term), and even the substances listed in the definition have some environmental impact associated with them. AnalyticalElemental analysis (within ±0.4% of the calculated value) is required to confirm 95% sample purity and corroborate isomeric purity. That’s why every Like the yield-based scale, the EcoScale gives a score from 0 to 100, but also takes into account cost, safety, technical set-up, energy and purification aspects. The atom economy calculation is a very simple representation of the “greenness” of a reaction as it can be carried out without the need for experimental results. To be published, work must present a significant advance in green chemistry. For all soluble polymers an estimation of molecular weight must be provided by a suitable method (for example, size exclusion chromatography, including details of columns, eluents and calibration standards, intrinsic viscosity, MALDI TOF, etc.)  In a chemical process, the reaction is usually reversible, thus reactants are not completely converted into products; some reactants are also lost by undesired side reaction. scijournal.org is a platform dedicated to making the search and use of impact factors of science journals easier. Occasionally the Editors may decide to publish something outside the defined scope of the journal if the work would be of interest to the green chemistry community and/or have the potential to shape the field.
Synthetic procedures must include the specific reagents, products and solvents and must give the amounts (g, mmol, for products; % for all of them), as well as clearly stating how the percentage yields are calculated. As only R is the useful product, the atoms of X, Y and Z are said to be wasted as by-products. Sequence verification also needs to be carried out for nucleic acid cases involving molecular biology. Authors are encouraged to provide copies of these spectra. We would like to thank our Editorial and Advisory Board members and all of our authors and referees for their contributions; this support is vital to the continuing success of Green Chemistry. Synthetic procedures must include the specific reagents, products and solvents and must give the amounts (g, mmol, for products; % for all of them), as well as clearly stating how the percentage yields are calculated.
The green chemistry concept does not create a conflict between fossil and renewable raw materials. The Journal Impact measures the average number of citations received in a particular year (2019) by papers published in the journal during the two preceding years (2017-2018). For crystalline compounds, the method used for recrystallisation should also be documented (that is, solvent etc). Synthetic procedures must include the specific reagents, products and solvents and must give the amounts (g, mmol, for products; % for all of them), as well as clearly stating how the percentage yields are calculated. Authors should provide at the time of submission a short paragraph explaining why their work justifies urgent publication as a Communication. The index is based on the set of the scientist's Produced annually, Impact Factors are calculated by dividing the number of citations in a year by the number of citeable articles published in the preceding two years. Read more about the 2012 Impact Factors on the RSC Publishing Blog. . Green chemistry, also known as sustainable chemistry is, among other things, the design of chemical products and processes to prevent potential pollution sources and use renewable materials. The key aim of Communications is to present innovative chemical concepts with important implications. The (currently) high profit margins within the sector mean that there is less concern about the comparatively large amounts of waste that are produced (especially considering the volumes used) although it has to be noted that, despite the percentage waste and E-factor being high, the pharmaceutical section produces much lower tonnage of waste than any other sector. This concept, however, covers consumer expectations in a sustainable environment and the efforts of the chemical industry to manufacture and supply useful products that are harmless and environmental benign. Abbreviation, The h-index is an author-level metric that attempts to measure both the productivity and citation Reaction mass efficiency, together with all metrics mentioned above, shows the “greenness” of a reaction but not of a process. It minimizes the negative impact of chemicals on the environment and helps in achieving sustainability in the chemical production. Referees will assess, as a whole, the evidence presented in support of the claims made by the authors. The synthesis of all new compounds must be described in detail. The requirements for characterisation criteria are detailed below. We are delighted to announce that Green Chemistry’s Impact Factor* has risen to a new high of 6.8! This metric is a good simplification for use in the pharmaceutical industry as it takes into account the stoichiometry of reactants and products. Green Chemistry continues to lead the field as the home of innovative research for the development of alternative green and sustainable technologies. Even though green chemistry concepts are significantly related to environmental and societal aspects, there are few documented attempts of integrating community-based service-learning into green chemistry courses. The cross-disciplinary nature of green chemistry also makes it possible to be taught in conjunction with other subjects, and many new green chemistry courses have been developed and integrated into curricula. This also includes avoiding potential environmental contamination via spills, leaks, and other types of accidents. A process that produces less waste may appear to be greener than the alternatives according to mass-based metrics but may in fact be less green if the waste produced is particularly harmful to the environment. 2019 Impact Factor. History. Led by Editorial Board Chair Philip Jessop (Queen’s University, Canada), we welcome urgent Communications and full Papers demonstrating key advances in sustainability, as well as Reviews and Perspectives. The twelve principles of green chemistry are—preventing wastage, maximizing atom economy, designing less hazardous chemical syntheses, designing safer chemicals and products, using safer solvents/reaction conditions, increasing energy efficiency, using renewable feedstocks, avoiding chemical derivatives, using catalysts, not stoichiometric reagents, designing chemicals and products that degrade after use, analyzing in real time to prevent pollution, and minimizing the potential for accidents.
