  • 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.














  • I don’t quite understand what the backlash is here. The article is about FAQs on the Mozilla website. It seems reasonable that some people might interpret “sell” to be accepting money to set the default browser to Google. Clarifying that on their site seems fine. The FAQ was surely never legally binding.

    Their ‘Terms of Use’ document is new as of Feb 26 AFAIK. Is that what people are upset by?
