Primary sources give details of experiments, results, and conclusions.
Try DragonSearch to find peer reviewed research articles from scholarly journals.
Journal articles can help you delve deeper into your topic than books and encyclopedias. Review articles will give you an overview of the state of a field over a period of time (pay attention to the publication date; they go out-of-date quickly). Research articles tell you exactly how a scientist performed his or her experiments and interpreted the results.
These resources help you find journal articles in various fields related to your projects.

Provides access to a comprehensive and reliable collection of scientific research information. A global network of scientists curate and aggregate the world’s scientific patent and journal content daily and make it fully discoverable. This ensures researchers have current and accurate substance, reaction, reference and commercial sourcing information available to quickly inform your critical research activities. SciFinder-n includes new predicted reaction steps in synthesis plans. These new predicted steps, produced by a CAS rules-based AI engine, will inspire new ideas for retrosynthetic routes to novel molecular entities.
Scopus is Elsevier's abstract and citation database launched in 2004. Scopus covers more than 36,000 titles from over 11,000 publishers, nearly all of which are peer-reviewed journals in top-level subject fields: life sciences, social sciences, physical sciences, and health sciences. It covers three types of sources: book series, journals, and trade journals. All journals covered in the Scopus database, regardless of who they are published under, are reviewed each year to ensure high quality standards are maintained. Searches in Scopus also incorporate searches of patent databases. Scopus gives four types of quality measure for each title; those are h-Index, CiteScore, SJR (SCImago Journal Rank) and SNIP (Source Normalized Impact per Paper).
Covers U.S. and international business and economic conditions, trends, corporate strategies, management techniques, marketing, product development, and competitive information. Content types include: scholarly and trade journal, magazine, and newspaper articles, working papers, conference materials, case studies, books, audio, video, and company, country, industry, and market research reports. The ABI/INFORM Collection is comprised of ABI/INFORM Dateline (local and regional business publications), ABI/INFORM Global (in-depth coverage from thousands of publications), and ABI/INFORM Trade & Industry (in-depth coverage of companies, products, executives, trends and other topics).
Provides access to full text scholarly journals and periodicals covering a wide-range of topics and disciplines. Allows filtering by peer-review and browsing by subject.

Standards are established norms or requirements for technical systems in industry.
Companies tend to file for patents instead of publishing in journals because a patent grants the holder exclusive use of the technology described for a set period of time (usually 20 years). 60-80% of material in the patent literature is published nowhere else. It is important for a company to understand the scope of protected technology to know in which areas they can freely operate.
United States Patent and Trademark Office (USPTO)
The USPTO offers web access to bibliographic and full-text patent databases. These databases provide full-text of patents from 1976 to the present and full page images from 1790 to the present.

The Intellectual Property Digital Library- WIPO GOLD-IP Reference Resource
WIPO GOLD is a free public resource which provides a one-stop gateway to WIPO’s global collections of searchable IP data. It aims to facilitate universal access to IP information. See International Patent Classification (WIPO). Use this tool to look up classifications on patents that interest you. Then, you can use them as search terms to locate related patents. The classifications, particularly in the chemical areas, are extremely detailed and group the patents nicely along types of technology.
These guides provide you with more in-depth information about various types of literature.
