This databases provide chemical and physical properties of materials.
Searches the NLM ChemIDplus database of over 370,000 chemicals and displays numerous properties (and sometimes lists citations for sources of the data, but it does not search article citations directly). Allows various search capabilities beyond the Lite version including chemical structure, toxicity, and physical property searching. You will need a web browser that has a recent version of Java installed. There is a structure drawing and display applet named Marvin. An alternative method to provide the capabilities needed to accept a structure query is the Chime plug-in.
Knovel provides a large collection of ebooks on engineering and related subjects. Each chapter is presented as a separate PDF. The entire collection is full-text searchable, and many results include interactive tables. Includes tables of properties for over 13,000 chemical compounds. Limited to simultaneous users.
Information on finding standards from ASABE, ASME, ASTM, IEEE, SAE J, military specifications, ordering standards via interlibrary loan, and standard indexes online.
This list of resources will enable you to retrieve most U.S. patents or trademarks, if you have a specific citation. However, if you have a product idea and want to determine if a similar item has been patented, searching these resources to determine patentability may be difficult.
