Do you work with chemical reactors? Are you curious about them? ASALI is the open-source code that you are looking for. Chemical reactor models, transport/thermodynamic properties of gases, equilibrium calculations. ASALI couples all these features with an user friendly graphical interface. Modeling chemical reactors has never been so easy.

nmrshiftdb2 is a NMR database (web database) for organic structures and their nuclear magnetic resonance (nmr) spectra. It allows for spectrum prediction (13C, 1H and other nuclei) as well as for searching spectra, structures and other properties. The nmrshiftdb2 software is open source, the data is published under an open content license. The core of nmrshitdb2 are fully assigned spectra with raw data and peak lists (we have pure peak lists as well). Those datasets are peer reviewed by a board of reviewers. The project is supported by a scientific advisory board. nmrshiftdb2 is part of the NFDI4Chem initiative (https://nfdi4chem.de/) and will provide a component for a curated repository there. ...

In the regulatory assessment of chemicals (e.g. under REACH), Quantitative Structure Activity Models (QSAR) are playing an increasingly important role in predicting properties for hazard and risk assessment. This implies both a need to be able to identify relevant QSARs and to use them to derive estimates and/or have access to their precalculated estimates. To help meet these needs, the JRC QSAR Model Database is established and freely accessible through http://qsardb.jrc.ec.europa.eu/qmrf The QSAR Model Reporting Format (QMRF) is a harmonised template for summarising and reporting key information on QSAR models, including the results of any validation studies. ...

Steam tables for industrial use according to the international standard for the properties of water and steam, the IAPWS-IF97 formulation and the international standards for transport and other properties. Hummeling Engineering BV develops engineering software in the fields of thermodynamics, mechanics, hydrodynamics, and digital signal processing.

...The models generated by this analysis can then be used to predict the properties of compounds during the development of new and novel drugs. The program and its databases are all open-source.

J-ICE stands for Jmol interface for crystallographic and electronic properties. Is an extension of the powerful, platform independent molecular visualizer Jmol, towards crystallographic and electronic properties. More info will be given soon.

The Gecko Hamaker open-source software project is a full implementation of the fully retarded Lifshitz formulations for isotropic and anisotropic plane-plane and cylinder-cylinder interactions with intervening interlayer materials, planar systems of up to 99 layers, and graded interfaces for the modeling of grain boundaries or other continuously changing systems, accompanied by a database of material optical properties spectra. The machine-readable optical property database is available for download and as a web service and makes available the full spectral optical properties of over 150 materials from both ab initio calculations and experimental measurements.

...The chemistry is handled using Chemistry Development Kit, this is proven code. The system holds atoms and bonds as entities in the rdbms, this makes it possible to have properties recorded using foreign keys and referential integrity. Apache Torque is used for database access. The build system of the project makes it possible to add properties directly to the molecule/atom/bond tables. This makes it more flexible than systems where structures are saved as monolithic blobs in a single table.

Information System "Supercritical Fluid Extraction" has developed as tool for collecting and analyzing the experimental data from various supercritical fluids experiments. The final target is to help to scientists who worked with supercritical fluids to predict some useful properties such as density, solubility etc. In order to calculate molecular descriptors, parse SMILES and another applied purposes is used Chemistry Development Kit (https://sourceforge.net/projects/cdk).

The Chemical Manager application can be of great help to Organic Chemistry Departments. University research groups will benefit from using this application, since it was optimized for their needs. Currently, Technion Chemistry department is benefiting from it.

Ever got confused while remembering all the various physical properties of all the standard 20 amino acids? Then use Amino Acid Finder!! It has a built-in database and contains information about all the physical properties and lets you to search them

EPeriodic is the electronic periodic table. you can read the properties of each element in the table with a single click
