Periodic Table Watch vs Open Access Helper

Two different Periodic Table clocks displays:  The simple clock display shows the Atomic Number and either Atomic Weight or Name. Colors indicate Phase: Solid, Liquid, or Gas. Tap to toggle seconds on or off; long-press to switch between Atomic Weight and Element Name. The Complete clock display shows all available information about each element. There's also a scrollable reference view that shows all of the elements, which can be set up as flashcards to test your knowledge.

Open Access Helper: Effortless Access to Scholarly Articles Unlock Open Access Easily find legal, free-to-read versions of paywalled scientific articles. Open Access Helper uses the trusted APIs from unpaywall.org and other sources to locate open access copies, making research more accessible for students, researchers, and curious minds. How It Works When you view a research article, the extension detects its DOI (Digital Object Identifier) and checks for an available open access version. Simply click the Open Access Helper badge to access the document! As you hover over the badge, it will indicate whether you’ll be accessing the “Published Version,” “Accepted Version,” or “Submitted Version.” EZProxy or OpenAthens Made Simple If your university library uses EZProxy or OpenAthens for off-campus access, this extension makes it seamless to connect. Just set your institution’s domain (e.g., harvard.edu), and with one click, you can proxy the current page through your library’s server. 100% Legal and Privacy-Respecting Every link provided leads to officially open-access or legally archived copies of research articles. Plus, Open Access Helper doesn’t collect personal data—just anonymous usage stats to improve functionality.
