The fabrication of the pre-ceramic paper

• (1) Preparation of an aqueous feed suspension
  containing filler and wood pulp or cellulosic
  fiber.
• (2) Coagulation of the fiber and filler in the
  suspension using polymeric additives, and
• (3) Formation of the paper sheet by dewatering
  the feedstock.

3
Intra- and intermolecular hydrogen bonds in two
adjacent cellulose molecules (according to Klemm
et al.22).

Paper Ceramic Loudspeakers

• Singaporean Yong Jieyus ceramic paper speakers
  (actually, theyre less speaker than amplifier)
  are made from clay, one of the best materials for
  sound amplification thanks to its low sound
  absorbent coefficiency and recycled music scores.
  Place your earphone inside each speaker and
  your tunes can be heard by all.The speakers are
  just a part of the research project into
  Noise/Sound that he is doing as part of his
  Masters degree at the Design Academy in
  Eindhoven.
