Modeling of an Enzyme-Based Biofuel Cell Anode

Enzyme-based biofuel cells (EBFCs) use biomass and specific enzymes known as biocatalysts in order to convert chemical energy into electrical energy. At the anode of an EBFC, the biomass (substrate) is oxidized to produce protons and electrons. Mediators are used in the anode to shuttle the electrons from enzymes to electrodes. At the cathode, the oxidant (oxygen) reacts with the protons and ...

HI Batch Reactor

This tutorial example illustrates the versatility of the *Reaction Engineering* interface. The hydrogen iodine reaction is modeled in a batch reactor with constant volume. Both isothermal and non-isothermal conditions are modeled.

Isothermal HI Reactor

For a perfectly mixed reactor with a predefined constant temperature, the reacting system’s energy balance is not needed to describe the system behavior. The behavior is defined as the composition and the production or consumption of species over time. Furthermore, because the reactor is perfectly mixed, the Reaction Engineering interface can also set up a model even though it has no information ...

Space-Dependent HI Reactor

This model deals with a reacting system comprising of an equimolar mixture of hydrogen and iodine gas which is allowed to react and form HI. Composition and temperature are allowed to vary both in space and time. This means that you have to define material balances, energy balances, and transport properties in the Reaction Engineering interface. These balances and properties are exported to ...

Nonisothermal HI Reactor

In the case of a perfectly mixed nonisothermal system, you have to set up both the time-dependent material and energy balances. There are no spatial concentration gradients because the system is perfectly mixed, so the Reaction Engineering interface can create a model without evaluating the material-transport properties.

Zone Electrophoresis - new

Zone electrophoresis (ZE) is an electrophoretic separation technique, typically used for analyzing proteins, nucleic acids and biopolymers. During the process, different species in a sample are transported in a continuous electrolyte buffer system, subject to a potential gradient. Due to differences in the mobilities, the species in the samples will eventually separate into different, well ...
