SweetMollyGrace is a suite of freeware tools for automating the work of rendering and animating molecules. Imports molecules in PDB, MOL XYZ format (Babel) Generates high quality images of molecules using raytracing tools (Povray and Raster3D). Makes 4 kinds of animation (only rotation around axes) using frames generated by Povray, Raster3D, Rasmol and Qmol. Saves animation in AVI, MPEG, GIF, MOV and FLIC. Generates and views 3D files.
NOC is a free program for protein structure model-building, visualization, validation and analysis. Features include: Auto-fit residues' side-chain against density data; Solid surface generation and electrostatic potential, hydrophobic force coloring; Potentials calculations; Customize molecular electronic density map contouring; Easy to add/delete heteroatom Group, residue. Easy to make an animated stream of a molecular model; WYSIWYG Labeling method; Easy to compare similar structures. NOC is free to students and educational institutions for non-commercial use.
Dhaatu : The Periodic Table of Elements 2.40 Extensive information for all of the 112 elements of the modern Periodic Table. Name, Symbol, Atomic Number, Atomic Weight. 1st and 2nd Ionization potentials, Electronegativity, Atomic Radius, Boiling Point, Melting Point, Electronic configuration and more.
This is a freeware computer program, designed for learning purposes, to calculate molar or formula masses, the calculations are shown together with the result. Most textbooks include an atomic mass table with values rounded to one or two decimals. For compatibility with answers on examples given in those textbooks McDalton Learning Edition includes the option to use a fixed number of decimals. This may also increase the readability of the output.
Extensive information for all of the 112 elements of the modern Periodic Table. Name; Symbol; Atomic Number; Atomic Weight; 1st and 2nd Ionization potentials; Electronegativity; Atomic Radius; Boiling Point; Melting Point; Electronic configuration.
Phoxel Periodic Table is a simple program that lets you choose any element from the periodic table and display all the information about it. You can also find the molecular weight and convert from grams-to-moles, moles-to-grams.
The global smash hit, all-purpose chemical drawing and graphics software. Use templates or free-hand, click and draw molecules, ions, stereobonds, text, polygons, arrows, etc. Automatic calculation of MW and formula. See estimates of density, refractive index, molar volume, etc. Now you can generate the systematic IUPAC name for small molecules, export structures in Chemical Markup Language (CML) format, convert SMILES strings to structures and structures to SMILES, and design input forms for ChemBasic programs with the Forms Manager feature.
Freeware DNA cloning, restriction analysis, primer site analysis and visualisation software. pDRAW32 is being developed as a freetime hobby project and it is far from finished, but as it has reached a point where it could be helpfull for many labs, it is now available to the scientific community. pDRAW32 is still in its betatesting stage, and it will probably remain that way for still some years to come. You are free to download and use pDRAW32 at your own risk. The only thing required of you is that you should report any bugs you may encounter.
An interactive Periodic Table of the Elements for Windows. This program takes full advantage of your computer's capabilities to give you an in-depth look at the the elements that make up our earth, the solar system, the galaxy.. well, let's just say everything.
CurTiPot pH & Acid-Base Titration Curves 3.1 CurTiPot pH & Acid-Base Titration Curves. A powerful all-in-one freeware for pH calculation, experimental data analysis and simulation of titration curves of acids, bases, salts and buffers (from simple solutions to complex mixtures), with interpolation, smoothing and nonlinear regression. Spreadsheets with graphics, examples, instructions, database and visual basic macros are self-contained in one XLS file; simply open-it with MS-Excel and start learning and working at home, classroom and laboratory.
Advanced Pathway Painter visualizes pathways providing the user with the ability to display any kind of quantitative data from gene and protein experiments directly within the pathways (colors represent the value). The linking between the pathway items and the experiment data is done over the gene or protein names and their accession numbers. Furthermore the user has a quick overview on the gene/protein with the collected links in the web-interface (direct links).
