Cell membrane research paper

Function and Structure of Cell membrane Definition of Cell membrane A Cell membrane is a thin semi-permeable membrane that surrounds the cytoplasm of a cell, enclosing its contents.

See our YouTube page: When a high salt and low salt solutions are placed into alternating membrane pairs the reverse electrodialysis RED stack produces additional voltage.

The salt solutions can be natural freshwater and seawater or regenerable solutions Cell membrane research paper waste heat such as ammonium bicarbonate. Extracting energy at higher voltages from MFCs can be challenging.

We developed a capacitor circuit system that efficiently increases the voltages produced by MFCs. You can read about it in Kim et al.

They can be autoclaved, and one power source can run thousands of reactors. Read more about how to make them in Call and Logan aor results using them in Call and Logan b. Visit our YouTube page to see how these are made and used 3 videos. It is liters, and it is a microbial electrolysis cell MEC that was used to treat winery wastewater.

The system is no longer running, but you can read about it in Cusick et al. Here the water is flowing through a series of 4 MDCs, so that the extent of desalination is increased.

The efficiency of the desalination is greatly improved compared to the 3-chamber single pair of ion exchange membrane systems shown below. A microbial desalination cell MDC can also be made to produce hydrogen gas, by adding voltage as done in a microbial electrolysis cell MECand by using ion exchange membranes.

We can this a microbial electrolysis desalination cell MEDC. You can read more about this in the paper paper by Mehanna et al. This reactor contains two membranes, and three chambers, with the water in the middle chamber desalinated when current is generated by bacteria.

The paper can be found on the publications page see Cao et al. Additional images are available for our new systems at: See the paper by Logan et al. This is our most frequently used reactor, which holds ml and is usually operated in fed-batch mode. We have used this system to examine a variety of factors that affect power generation, such as electrode spacing, solution chemistry, electrode materials, substrates and pure vs mixed cultures.

This reactor has a flat anode and a flat cathode. See publication by Liu and Logan In order to scale up MFCs, we need to provide more surface area for the cathode. This is a reactor we tested using tubular cathodes made of ultrafiltration membranes that were coated on the inside with catalyst and a carbon conductive paint and a Pt catalyst.

See the publication by Zuo et al. This is a single chamber MFC that uses a very large brush anode and a flat cathode. This reactor is red due to the growth of Rhodopseudomonas palustris DX Power is very much limited by the cathode surface area, but it is a nice easy design that can be made out of glass, plastic or just about any material.

See Logan et al. This is the same cube reactor as above with a brush anode, but this one has a pure culture of Rhodopseudomonas palustris DX See paper by Xing et al. This is a two-chamber reactor modified to have a crimp top on the reactor top and a crimp top side access port. The brush is suspended in the solution.

This flat plate microbial fuel cell, that operates in continuous flow mode, has a proton exchange membrane sandwiched between two carbon paper electrodes. Channels are drilled to that the flow follows a serpentine path through the system. This is a conventional two-chamber microbial fuel cell.

In this setup, both chambers are gas sparged: Same as the above cell, except the anode chamber is filled with a wastewater solution.

Same as above, but filled with wastewater. A data logging multimeter is used to monitor voltage in the circuit containing a resistor. From the voltage and resistor information, we can calculate total power output by the system.Term Paper on Plasma Membrane | Cell Organelle | Cell Biology.
