Open Source Visual Basic .NET Chemistry Software

DWSIM is an open source, CAPE-OPEN compliant chemical process simulator for Windows, Linux and macOS systems. Written in VB.NET and C#, DWSIM features a comprehensive set of unit operations, advanced thermodynamic models, support for reacting systems, petroleum characterization tools and a fully-featured graphical interface. DWSIM Pro is a commercial sibling of DWSIM built on top of open-source software. It offers extended features, comes with private support, and is accessible in the cloud.

MoCalc2012 is a simple, efficient Graphical User Interface for MOPAC, DFTB+, GAMESS(US), Firefly, NWChem, ORCA and PSI4.

This application lets STM or AFM images AND molecular models to be overlaid. It is useful to understand how your molecules fit to what you observed and can help interpret your data. What makes this application more useful than paint programs (powerpoint or inkscape) is the fact that the size of the images and of the molecule is fixed, so that you know that you are working in real space.

PTable is a lightweight and easy to use application hat aims to bring you more information about the chemical elements which are represented in the periodic table. Besides the colored grouping, PTable is able to display details about any element you click onto. Thus, you can view the atomic number, symbol, common name, atomic weight, density, state and much more.

Solve equations, view charts and graphs, make conversions, balance equations and more. Chemistry Calculator.

The Insecticide Resistance Monitoring Application

This is a ActiveX/ATL component that shows molecular structures in 3D. It can read atomistic .pdb and .xyz file formats. This control is made very simple and flexible. It may be useful for chemists or other scientists to put molecular structures in presentations such as power point, with the ability to rotate or zoom using the mouse. It can also be used in developing graphical user interface for molecular calculations, and in any programming IDE that allows insertion of ActiveX controls. The models are rendered using OpenGL, therefore it exploits optimizations provided by the graphics cards. NEW: Render as PNG with transparent background. Added small application that allows user to open molecular file and render it as a PNG file image PNG with transparent background. Can be quite useful in presentations and visual processing.
