Luscus is the program for graphical display and editing of molecular systems. The program allows fast and easy building and/or editing different molecular structures, up to several thousands of atoms large. Luscus can also visualize dipole moments, normal modes, molecular orbitals, electron densities and electrostatic potentials. In addition, simple geometrical objects can be rendered in order to point out a geometrical feature or a physical quantity. The program is developed as a graphical interface for MOLCAS program package, however it's adaptive nature makes possible using luscus with other computational program packages and chemical formats.

NanoHive is a modular simulator used for modelling the physical world at a nanometer scale. The intended purpose of the simulator is to act as a tool for the study and development of nanotech entities. The project will also focus on the simulation of complex biological applications such as Targeted Drug Delivery by simulating nanowires, magnetic nanoparticles and others. Updates will follow from January 2017.

"E-plater" is a device that was specially developed by Engenharia Caseira (engenhariacaseira.com.br) to make pulsed and reversed pulsed electroplating (PED). Research shows that molecules on the surface of electrically deposited material using direct current are sometimes disorganized which can result in uneven surface and color. It is possible to control the composition and thickness of the deposited layer in an atomic order by configuring the amplitude and width of a pulse. The pulses favor the initiation of grain nuclei and increase the number of grains per unit of surface resulting in the thinner deposit with better properties.

FullFun (stand for Fullerene Functionalization) is an open source software package, licensed under the GNU General Public License (GPL). It provides an efficient and easy way to generate, analyze and predict fullerene-related structures. The package consists of four programs: CSIOpt, XSI, XSIOpt and bkcage. They are implemented using the C and C++ languages and distributed under an open source licence. The code can be compiled and executed on Linux, Mac OS X and Windows (via DOS) operating systems. The bkcage program for general purposes of generation, identification and nomenclature of fullerene structures. It can print out all all kinds of topological information. The CSIOpt program predicts the most stable isomers of charged fullerenes and endohedral metallofullerenes. The XSIOpt program predicts the most stable addition patterns for a given endohedral fullerene C2nX2m. For downloading FullFun, please go to our new web page: https://campusys.qui.uam.es/?page_id=1491
