Over 1,000,000 page views per month. Jmol/JSmol is a molecular viewer for 3D chemical structures that runs in four independent modes: an HTML5-only web application utilizing jQuery, a Java applet, a stand-alone Java program (Jmol.jar), and a "headless" server-side component (JmolData.jar). Jmol can read many file types, including PDB, CIF, SDF, MOL, PyMOL PSE files, and Spartan files, as well as output from Gaussian, GAMESS, MOPAC, VASP, CRYSTAL, CASTEP, QuantumEspresso, VMD, and many other quantum chemistry programs. Files can be transferred directly from several databases, including RCSB, EDS, NCI, PubChem, and MaterialsProject. Multiple files can be loaded and compared. A rich scripting language and a well-developed web API allow easy customization of the user interface. Features include interactive animation and linear morphing. Jmol interfaces well with JSpecView for spectroscopy, JSME for 2D->3D conversion, POV-Ray for images, and CAD programs for 3D printing (VRML export).

A simple periodic table of elements viewer using elementary and edje.

ElemenTable is a colorful periodic table of elements application for Windows (requires .NET Framework v.4.5 or higher). It gives many important information, e.g. atomic mass or electronegativity, about all current chemical elements from Hydrogen [1] to Oganesson [118]. All elements are ordered in a colorful periodic table layout which can be changed in color to show either the element groups, the element states or the element types. The data of the chemical elements is hosted at https://github.com/bluegrams/Periodica.Data. Also have a look at the new periodic table app for Windows 10 with many more features at https://www.microsoft.com/store/apps/9PB2TD7P6DT3.
