    The low-temperature and high-temperature water gas shift catalysts have kind of conflicting requirements for proper operation. The former is active when it's reduced to the metallic form and becomes pyrophoric; the latter is active when it's reduced to…

    Will the calcite crystals (crushed by the burnishing step) retain their structure in a low pressure hydrogen atmosphere in contact with nickel/palladium (i.e. by extension, catalytically-split atomic hydrogen) at elevated…

    I indeed got tricked by them being visible in high contrast in the SEM photos. My main point was that if such crystals were clearly noticeable (perhaps even in the form of an opaque layer if seen from a distance) they would have probably been…

    So many questions could be asked, but were the calcite crystals visible to the naked eye like the microscope photos appear to suggest? I guess I'm imagining a situation similar to the photo attached below.

    I am still wondering about using an oxidized mesh or other support, possibly in the form of a sheet.

    After yesterday's discussions during the MR test, today I took a slightly oxidized carbon steel blade, sanded down 4/5 of it with 80grit skateboard grip…

    Yesterday I assembled a graph by sampling some datapoints manually from live dashboard data:



    T Optris decreased after changing thermal camera temperature range.

    Temperatures from the 40W and 80W power steps seemed to be in line with the previously provided…

    That sounds similar to what I also have to normally do in the atmosphere, although at the relatively low voltage I'm using the electrodes have to almost (but not quite) touch to start a discharge.

    I initially saw that EM noise would get…

    Ingenious; thanks for the description.

    Is the gap adjustable while it's operating? I found that (at least at atmospheric pressures and probably somewhat larger currents than in your case) when the two brightest glow discharge regions at the…

    Cool. Is the left electrode the cathode (−) ?
    I'm not sure if this is the proper thread to discuss about this more seriously, but to come up with something as depicted in the photo what does it take more in detail (parts/costs) ?

    The previous paper provided in tables 1 and 2 a similar number of tests for either method; I was basing my opinion on this data.

    According to Mizuno, that's because it was more complex, took a very long time to complete and it kept more equipment busy for a longer time, thus decreasing the amount of experimentation that could be accomplished for a given time interval.

    In his previous two reactor iterations, Mizuno reported explicitly connecting the reactor walls to ground, with the mesh electrically in contact with them. That was when he initially glow-plasma sputtered Pd on the mesh (as the…

    Mizuno used to apply Pd with an electroless plating solution, but eventually settled with the burnishing process as it was cheaper (and possibly more effective).

    Has Mizuno considered Edmund Storms' suggestion of using a metal sheet instead of a mesh (see source 1 and source 2) ? It could increase the amount of Pd deposited due to the larger usable surface area compared to a mesh and…

    Ed Storms also thinks that the gaps formed after unloading will remain stable only as long as some hydrogen still exists inside of them, so it will be probably best not to put too much emphasis on pumping out all of the hydrogen after…

    On a possibly related note, in his 1980–90s work on thermionic emitters—before focusing on iron oxide catalysts at lower temperatures—Holmlid found that alkali atoms desorbing from metallic foils like Ir or Pt at high temperature would form excited…

    The main issue is that small amounts of that catalyst (obtained only when suitably activated—it's not stable in air and the precursors are Fe2O3 and K2CO3/KOH are not active on their own) might not necessarily dissociate well large enough…

    If the reaction is occurring predominantly on the outer surface of the mesh, carbon could possibly have a role and there are instances where it might be inadvertently indirectly introduced in a less than optimally maintained high…

    There's also the fact that you have a metal that expands considerably upon absorbing hydrogen and forming a hydride (Pd) getting basically cold welded to one that does not expand significantly and does not form a hydride under ordinary…
