In order for BCREC Group to publish and disseminate research articles, we need non-exclusive publishing rights (transfered from author(s) to publisher). This is determined by a publishing agreement between the Author(s) and BCREC Group. This agreement deals with the transfer or license of the copyright of publishing to BCREC Group, while Authors still retain significant rights to use and share their own published articles. BCREC Group supports the need for authors to share, disseminate and maximize the impact of their research and these rights, in any databases.
As a journal Author, you have rights for a large range of uses of your article, including use by your employing institute or company. These Author rights can be exercised without the need to obtain specific permission. Authors publishing in BCREC journals have wide rights to use their works for teaching and scholarly purposes without needing to seek permission, including:
Authors/Readers/Third Parties can copy and redistribute the material in any medium or format, as well as remix, transform, and build upon the material for any purpose, even commercially, but they must give appropriate credit (the name of the creator and attribution parties (authors detail information), a copyright notice, an open access license notice, a disclaimer notice, and a link to the material), provide a link to the license, and indicate if changes were made (Publisher indicates the modification of the material (if any) and retain an indication of previous modifications using a CrossMark Policy and information about Erratum-Corrigendum notification).
Authors/Readers/Third Parties can read, print and download, redistribute or republish the article (e.g. display in a repository), translate the article, download for text and data mining purposes, reuse portions or extracts from the article in other works, sell or re-use for commercial purposes, remix, transform, or build upon the material, they must distribute their contributions under the same license as the original Creative Commons Attribution-ShareAlike (CC BY-SA).
The Authors submitting a manuscript do so on the understanding that if accepted for publication, non-exclusive right for publishing (publishing right) of the article shall be assigned/transferred to Publisher of Bulletin of Chemical Reaction Engineering & Catalysis journal and Department of Chemical Engineering Diponegoro University/Masyarakat Katalis Indonesia - Indonesian Catalyst Society (MKICS) (or BCREC Group).
Upon acceptance of an article, authors will be asked to complete a 'Copyright Transfer Agreement for Publishing (CTAP)'. An e-mail will be sent to the Corresponding Author confirming receipt of the manuscript together with a 'Copyright Transfer Agreement for Publishing' form by online version of this agreement.
Bulletin of Chemical Reaction Engineering & Catalysis journal and Department of Chemical Engineering Diponegoro University/Masyarakat Katalis Indonesia-Indonesian Catalyst Society (MKICS), the Editors and the Advisory International Editorial Board make every effort to ensure that no wrong or misleading data, opinions or statements be published in the journal. In any way, the contents of the articles and advertisements published in the Bulletin of Chemical Reaction Engineering & Catalysis are sole and exclusive responsibility of their respective authors and advertisers.
Remember, even though we ask for a transfer of copyright for publishing (CTAP), our journal Author(s) retain (or are granted back) significant scholarly rights as mentioned before.
