text: Yo, check it out, I'm 'bout to spit some knowledge,
  Using scanning electron microscopy, transmission electron microscopy,
  X-ray absorption near edge structure, and extended X-ray absorption fine structure X-ray diffraction,
  We showin' MnCO3, MnWO4, Mn3(PO4)2·3H2O, MnS, and Mn(VO3)2·xH2O,
  Under water-oxidation conditions, with cerium(iv) ammonium nitrate in tow,
  They be convertin' to Mn oxide, no high-range order, yo!
  We got a mechanism, a theory in sight,
  Mn oxide, an efficient water-oxidizing catalyst, that's right!
  It's a candidate, a contributor to the catalytic activity we see,
  So listen up, 'cause this discovery's a key!
