The RAPRA, CEABA, and TEMA databases have resumed weekly updating on STNext. Backfile data from April 2022 to the present, previously unavailable in the databases, has been added to each of them. Weekly (default) and monthly SDIs are now also available. The databases are produced by WTI AG.
- RAPRA (Polymer Library) covers information on rubber, plastics, adhesives and polymer composites, beginning with 1972.
- CEABA (Chemical Engineering and Biotechnology Abstracts) covers chemical engineering and biotechnology, from 1966 to date.
- TEMA (Technology and Management) is a multidisciplinary technology database including business information relevant for management. It is especially helpful for searches in the areas of medical engineering, textile and paper, energy, mechanical and plant engineering as well as information technology. Coverage begins with 1968.
