Can Cement or solid paper work as Proton exchange membrane for MFC?
I'm planning to create a microbial fuel cell. Initially, im planning to use a Salt+agar mixture for my PEM but halfway into my project, i've been wondering if paper soak with NaCl solution or cement with NaCL could work. can anyone answer my question. thank you
Difference between Gel Battery And VRLA Battery?
A VRLA battery (valve-regulated lead-acid battery), more commonly known as a sealed battery or maintenance free battery, is a type of lead-acid rechargeable battery. Gel Cell, Absorbed Glass Mat (AGM), and Wet Cell are various versions of lead acid batteries. The Wet comes in two styles: serviceable, and maintenance free. Gel Cell and the AGM batteries are specialty batteries that typically cost twice as much as a premium Wet Cell battery.
What is true about an electrolytic cell?
A.Oxidation occurs at the anode.B.Reduction occurs at the cathode.C.Electrical energy is converted to chemical energy.The negative terminal of the voltage source is attached to the cathode.
How is electrochemistry applied to industrial processes?
Electrochemistry consists of a variety of diverse and significant applications to modern industrial and commercial processes in the 21st Century. These applications most commonly include the purification of metal and the ability to convert the chemical energy of a simple voltaic cell reaction into electrical energy.
What kind or type of machine converts chemical energy to mechanical energy?
A battery changes stored chemical energy into electrical energy by passing electrons from high to low potential materials within the battery.
Advantages of membrane cell - chloralkali process?
advantage of membrane cell
What are the applications of polymers in medical field?
The chemistry industry is working on new uses for polymers as well. In development are conductive polymers for printable electronics. Polymer Electrolyte Membrane, PEM, (or Proton Exchange Membrane) fuel cells are already in use in hydrogen fuel cell vehicles. The industry is also working on materials for advanced fuel cells including a polymer electrolyte fuel cell (PFC).
What is the fuel used in a fuel-cell automobile?
Fuel cells come in many varieties. Low-temperature designs such as proton exchange membrane fuel cells [PEMFC's, also known as polymer electrolyte membrane fuel cells] are mostly aimed at portable and transport applications
Why is cell membrane differentially permeable?
Selective (or differential) permeability allows the cell to regulate its internal environment and maintain internal homeostasis. This is also the basis by which a neuron (nerve cell) can 'fire' and send a message along its axon - it selectively allows one electrolyte then a different electrolyte to flow across its cell membrane and change the electrochemical gradient.
The eukaryotic cell has multiple membrane-enclosed compartments This evolutionary innovation provides what advantage to the cell?
The different membrane-enclosed spaces allow different parts of the cell to perform specific functions.
What is the advantage of having a folded membrane surrounding the cell or within the cytoplasm or within organelles?
It increases the surface area of the cell membrane. By having more surface area, more matter can be moved in and out of the cell.
What is the advantage of the presence of on cell membranes?
the membrane has a greater surface area for an increased rate of diffusion
What regulates passage of materials into and out of cells?
The cell membrane controls movement of materials in and out of the cell.
Does peptidoglycan lack a membrane enclosed nucleus?
Well...technically yes. It should be taken into consideration that peptidoglycan is a polymer that a bacterial cell wall is composed of. Therefore, it is not alive and technically lacks a membrane. On the other hand, the cell on which the peptidoglycan is present lacks a membrane enclosed nucleus, thus making it prokaryotic.
Which cell structure controls what enters and leaves the cell?
The selective permeability of the cell membrane
What cell structures are made primarily from phospholipids?
cell membrane
What structure controls the passage of substances into and out of the cell?
cell membrane
