    Electrochemistry cathode question

    Well what about a pressure measurement. Given that there should be no formation of other gas could I use a change in pressure to tell the hydrogen amount. Based upon partial pressure and we have a a 2:1 relationship between the hydrogen and oxygen. I think I would have to assume Ideal gas but it...

    Electrochemistry cathode question

    Would this even be possible to measure this on a Nano-scale? I know how many electronvolts I am putting into the system but so far current research says there is only about 7%-15% efficiency. Also different doping agents I add to the system lower or raise the band gap of the material and effect...

    Electrochemistry cathode question

    How would I go about that and I assume you are talking about the 2 electron difference from cathode to anode

    Electrochemistry cathode question

    The reaction produces μmol and it won't give me the Hydrogen production rates

    Electrochemistry cathode question

    You are right I have neither training in electrochemistry nor photochemistry in fact I am a physics undergrad. I was trying to get some insight on the reactions that are taking place on the surface of my material I am working with. I think however I that what I meant by OH radicals is in fact...

    Electrochemistry cathode question

    That's what I was afraid of. I was hoping that there would be an easier method into looking at the production of Hydrogen and Oxygen without using a gas spectrometer. I was hoping for the OH radicals to remain and I could use a simple PH meter to indirectly get how much H2 was being produced

    Electrochemistry cathode question

    The hole is taken care of by the Anode region Anode (oxidation): 2 H2O(l) → O2(g) + 4 H+(aq) + 4e− So we have a net of 2 electrons the formation of H2 and O2 gas but what happens to the H+ ions and OH- ions do the recombine to from water, hydrogen peroxide, H3O. In normal electrolysis they have...

    Electrochemistry cathode question

    I am currently looking into photocatalytic materials. Now I might be over simplifying this process but it my observation that I am just looking at electrolysis but instead of electricity provided by a battery I am using electron hole pairs to generate a potential to do my splitting. My question...

    Solving Heat Transfer Problem for Hydrogen Flow

    Yeah i think i determined the work output to be W=n*R*Ln (V2/V1)*(Th-Tc) the problem is that I don’t know how hot the hydrogen gas gets. I was thinking that I can use Q=C(∆T) so I can figure how hot my heat exchange box gets from the original thermo processes. Then use how hot it gets along with...

    Solving Heat Transfer Problem for Hydrogen Flow

    The problem with mass flow is that it’s not a steady state problem. At least I don’t think it is. I am using hydrogen as the medium of the stirling engine because its high R value will help in when calculating work out. I am also hydrogen as the coolant for because of its thermal properties. I...

    Solving Heat Transfer Problem for Hydrogen Flow

    I have a quick question that maybe someone can help me out with. Let’s say I have an object that has a heat output of 48.7 KJ that is constant and it is surround by hydrogen that it flowing around it. Like a rock in a stream. If I know the starting temp of the hydrogen how would I determine how...

    What are the properties of Dirac notation and operators?

    Thank you so much for the help. You are a lifesaver

    What are the properties of Dirac notation and operators?

    Since there is no complex number involved with the would it just be that ( A | a \rangle )^\dagger = \langle a | A^* , is equal to \langle a-1 | \sqrt{a} , and the answer be \langle a-1 | \sqrt{a} \sqrt{a}|a-1\rangle . or a*<a-1|a-1> sorry just having a hard time seeing this its hard...

    What are the properties of Dirac notation and operators?

    Ok so in this case (\langle a | A^\dagger) = (A | a\rangle)^\dagger, would that make it equal to \sqrt{A}|(a+1) and then how do you take the adjoint of that expresion
