Explore molecule shapes by building molecules in 3D! Find out how a molecule's shape changes as you add atoms to a molecule.

This function generates so called Mackay-Icosahedron. In this function it's possible to change distance between atoms (bonding length) number of shells and also composition of two different kinds of atomsUse following piece of code to visualise the particle:radius = 1; details = 15;for...

Swiss-PdbViewer (aka DeepView) is an application that provides a user friendly interface allowing to analyze several proteins at the same time. The proteins can be superimposed in order to deduce structural alignments and compare their active sites or any other relevant parts. Amino acid...

Some of the logic from this program was provided from PDBRead.m by Sachin Nikumbh. The version I made is a trimmed down version of it that only outputs the data from one atom type (protein by default), and formats it as convenient cell variables. For smaller PDB files, the time difference between...

NanoVis (beta version) allows to visualize any atomistic structure by reading a user defined file. The supported formats are "gen" and "xyz". There are two display modes: normal and "spacefill". In the zip file, with the .m file, there are two examples of structure and a file containing the atoms...

AVSEQ (which we pronounce "A-V-Sekk") is an audio-driven game based on an installation design by our chief programmer, Tom Betts, who multi-classes as an artist and musician. The idea behind the project was to create a challenging, abstract action game in which you link up atoms to obtain a high...

A capacitor is a device for storing charge. In this simulation, you can investigate a relatively simple capacitor, known as a parallel-plate capacitor. It consists of two identical metal plates, placed parallel to one another. The capacitor can be charged by connecting one plate to the positive...
