Open Source Chemistry Software

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).

JSmol is the extension of the Java-based molecular visualization applet Jmol (jmol.sourceforge.net) as an HTML5 JavaScript-only web app. It can be used in conjunction with the Java applet to provide an alternative to Java when the platform does not support that (iPhone/iPad) or does not support applets (Android). Used in conjunction with the Jmol JavaScript Object (http://wiki.jmol.org/index.php/Jmol_Javascript_Object), JSmol seamlessly offers alternatives to Java on these non-Applet platforms. JSmol can read all the files that Jmol reads. You can do all the scripting that Jmol does. You can create all the buttons and links and such that you are used to creating for Jmol. All of the rendering capability of the Jmol applet is there. JSmol has both a console and a popup menu. JSmol is integrated fully with JSME and JSpecView. A "lite" version of JSmol provides minimal functionality (balls and sticks only) for extremely small-bandwith apps. Released 1/12/2013

STT - Simulador para Trocadores Tubulares Simulador para trocadores de calor dos tipos: bitubular e casco e tubos. O software utiliza o método Kern para cálculo de trocadores de calor, possui base de dados atualizável para as propriedades dos fluidos e dimensões dos tubos, facilitando o uso e minimizando a entrada de dados. O STT trabalha no sistema de unidades internacional e no sistema inglês e possui interface para sistema operacional Windows (XP, 7, Vista)

Small and fast software that calculates the molar mass of a chemical formula. Can redirect user to the wiki page of the compund or to the NCBI chemical database. Multilanguage.

This is a continuation of the OpenGamma project by Marcelo Maduar with his permission. It is for gamma ray (radiation) spectroscopy and isotope identification. It accepts output files from several types of MCA's. Real time input will be added.
