This program allows the conversion of lenght, weight, power, energy, liquids, temperature, pressure, clothing, from and to Metric units.

BATE calculates pH of solutions containing mixtures of acid and base with up to 4 dissociation steps and titration curves for these acids and bases. ionic strentgh can be calculated, omitted or forced. Program contains editable database of common weak acids and bases and accepts acid and base dissociation constants and protonation constants as input. Built in calculator allows easy calculation of molar masses and concentrations for given formula.

Design batteries or learn about oxidation and reduction by building cells. Drag-and-drop electrodes from the Electrode Selector or randomly generate one. Alter cell properties such as temperature, pH, concentration and pressure and see its effect on the cell. Add new half cells with the Half Cell Editor. Customize cell colors, gases and non-ionic solutions. Copy and paste to a word processor, print directly or save as a picture file.

Intelli Balancer is the best chemical equation balance software, it can balance any chemical equation in a flash! it has a feature rich editor so that you can edit chemical equations easier.It support almost all kinds of chemical equations,freelancer tng eg: ionic equation and equation with hydrate.

Unique interactive multimedia Chemistry teaching software that tests students as they learn. Topics covered include: elements, atoms and molecules, word equations, chemical symbols, Periodic Table and chemical formulas. Plus interactive simulations to teach the balancing of chemical equations and the formulas of ionic compounds. As far as possible, skills are taught through familiar examples, to help reinforce general chemical knowledge. Written by a teacher for use in schools, but an excellent personal tutor for anyone beginning to study Chemistry. Questions constantly test understanding and hints are given when answers are wrong.

Chemistry teaching software which simulates the bonding of ionic compounds on screen. Learn how ionic compounds are formed by atoms gaining and losing electrons. Includes a reference section to support students learning with basic facts and information. Price includes full site license. Use as a demonstration tool (using a projector), as a teaching tool - get pupils to access the reference sections before attempting the simulation, or as a revision tool prior to tests or exams.

CESE is an integrated environment for performing computational simulations using a variety of electrophysiological models.
At this stage CESE allows creation and execution of the single-cell models (containing both Hodgkin-Huxley (HH) and Markovian current formulations). Models of electrical activity of cardiac myocytes with source code are included in the CESE distribution. We hope to extend the number of available models, and add certain neuronal models in the future.
The main strength of CESE is in its uniformity — a program interface remains the same for different types of models. You can easily switch between models and compare simulation outputs. Model parameters can be modified, selected for output and/or clamped in the same, standard way.
CESE extends the conventional electrophysiological meaning of the "voltage clamp". You can clamp virtually any model variable, including voltage (membrane potential), total or individual ionic currents, ionic concentrations, temperature, gating variables, etc. The clamping commands can be complex piece-wise functions, individually set for the model variable of interest. This opens endless possibilities for the exploration of complex model behavior.
CESE provides simple, but efficient data visualizations. Simulation results can be presented in the graphic and tabulated forms. Plots can be customized, and regions of interest zoomed.
Even though CESE was not designed to be a data analysis tool, you can generate current-voltage relationships (I-Vs) and calculate statistical parameters for a given signal within the program. You can export your data to ASCII, Axon Text File (ATF), and NetCDF formats to continue analysis in your favorite package.
