Chempedia is the free and open chemical substance registry. It enables anyone to register, at no cost, individual substances through a Web-based interface. Each substance receives a unique, numerical, checksummed identifier that can be used anywhere and looked up at no cost. Each substance also gets a canonical URI from which everything that is known through Chempedia can be found.

Chempedia uses a streamlined from of peer review that combines concepts used in traditional peer review with experiences learned from modern social media.

Scirus is a comprehensive science and engineering specific search engine that searches open-access websites as well as peer-reviewed content from publisher sites.  With over 450 million scientific items indexed at last count, it allows researchers to search for not only journal content but also scientists’ homepages, courseware, pre-print server material, patents and institutional repository and website information.

Scirus is also linked from Databases/Article indexes for Engineering or it can be found by searching on our Library’s online catalog in the ‘Title’ field.

Thomas Fuller, SF Environmental Policy Examiner, analyzed nanotechnology patents using ‘Advanced Search’ feature in scirus.   He found records of 8,007 patent filings for nanotechnology.  According to Fuller, “Of those 8,007 patents that have nanotechnology in the title, abstract or text, 7,007 were filed in the past 5 years.  That’s 88%. Almost a quarter–23%–were filed last year alone. That’s one reason why I think nanotechnology will be to this century what electricity was to the last.” He also writes, “the recovery of the American economy and progress to unprecedented heights over the next 10 years would be led by nanotechnology, bio-technology and robotics.”

With Google Trends, you can compare the world’s interest in your favorite topics. Enter up to five topics and see how often they’ve been searched on Google over time. Google Trends also shows how frequently your topics have appeared in Google News stories, and in which geographic regions people have searched for them most.

I tried experimenting by searching different chemicals in Google Trends.

For example, searching for Acetic Acid, retrieved a news story about projected forecast for the world market of Acetic Acid by the year 2015.

World Market for Acetic Acid Projected to Reach 11.8 Million Tons in 2015, According to New Report by Global Industry Analysts, Inc.

The Chemical Database database will allow the user to retreive information for any of 25,496 hazardous chemicals or ‘generic’ entries based on a keyword search. Potential keywords include names, formula and registry numbers (CAS, DOT, RTECS, EINECS, Beilstein and Merck). Formula are represented in Hill format for searching and a more descriptive format for viewing.

The U.S. Department of Energy (DOE) announced the launch of a Web site, DOepatents, which allows search and retrieval of information from a collection of more than 20,000 patent records. The database represents a growing collection of patents resulting from R&D supported by DOE. DOEpatents consists of bibliographic records, with full text where available via either a PDF file or an HTML link to the record at the U.S. Patent and Trademark Office.

The Energy Citations Database (ECD) provides free access to over two million science research citations from 1948 through the present, with continued growth through regular updates. There are over 140,000 electronic documents, primarily from 1994 forward, available via the database. Citations and documents are made publicly available by the U.S. Department of Energy (DOE). ECD includes scientific and technical research results in disciplines of interest to DOE such as chemistry, physics, materials, environmental science, geology, engineering, mathematics, climatology, oceanography, computer science and related disciplines. It includes bibliographic citations to report literature, conference papers, journal articles, books, dissertations, and patents. ECD was created and developed by DOE’s Office of Scientific and Technical Information.
