Deletion of The Investigation of Nanoparticle from Sol-Gel Method

Comment: an overly technical article, possibly |a synthesis of sources, which could be included in Nanoparticle#Sol-gel or Brownian motion.  I actually own an English translation of Albert Einstein's monograph on Brownian motion and related topics, which would be a "better" source than his original, primary, groundbreaking 1905 article
