text: Yo, check it out, here's the scoop
  Exotic hierarchical rutile TiO2 nanostructures, we produce
  Surfactant free, hydrothermal route, single step
  Synthesized, no doubt, no need to fret
  
  We vary the reaction temperature, that's the key
  From 140°C to 200°C, let's see what we can see
  Investigating the properties, oh so fine
  Of the synthesized rutile-TiO2, it's our prime
  
  X-ray diffraction, X-ray photoelectron spectroscopy
  Raman spectroscopy, UV-vis spectroscopy
  Scanning electron microscopy, we got the tools
  Characterizing the nanostructures, breaking the rules
  
  These TiO2 samples, they got the power
  Photoelectrochemically active, shining like a tower
  And the best performance, let me tell you straight
  Got it at 180°C, that's the perfect rate
  
  Now listen up, I got a theory to share
  A growth mechanism, temperature's the flare
  Photochemically active, TiO2 films so thin
  That's the result, the game we win
