  • The new material has eight times better performance than pure cubic silicon carbide

    Nowhere is it stated how efficient either material is, other than to say that the researchers are 5-10 years away from a material that’s 10% efficient. So they must have an efficiency of less than that I guess.

    From the paper, the closest I can see is:

    The applied bias photon-to-current efficiency (ABPE) of the Ni(OH)2/Co3O4/3C-SiC photoanode reached 0.47% at 0.65 V vs RHE, which is 15.6 and 1.8 times higher than that of the 3C-SiC and Co3O4/3C-SiC photoanodes, respectively (Figure 4b)

    I don’t know how representative that measurement is though.





  • There are still opposite charges - each colour has an ‘anti’-colour. So R+R=colourless G+G=colourless etc. This is how mesons work (pairs of quarks). Baryons are triplets of quarks but there are also combined tetra- and pentaquark states also.

    You can think of anti-red as being cyan etc. but the colour theory can be more confusing than it’s worth.
