Mixed office paper (MOP) pulp without deinking with an ash content of 18.1 ± 1.5% was used as raw material to produce nanofiller-paper. The MOP pulp with filler was mechanically fibrillated using a laboratory stone grinder. Scanning electron microscope imaging revealed that the ground filler particles were wrapped by cellulose nanofibrils (CNFs), which substantially improved the incorporation of filler into the CNF matrix. Sheets made of this CNF matrix were densified due to improved bonding. Specific tensile strength and modulus of the nanofiller-paper with 60-min grinding reached 48.4 kN·m/kg and 8.1 MN·m/kg, respectively, approximately 250% and 200% of the respective values of the paper made of unground MOP pulp. Mechanical grinding duration did not affect the thermal stability of the nanofiller-paper.

A study of 15 patients with 17 tympanic membrane perforations resulting from water sports was carried out. Most small perforations healed spontaneously. Perforations that persisted after 8 weeks were treated surgically, usually with the office paper patch procedure. A frequent history of middle ear problems in these patients suggests that middle ear dysfunction may play a role in the occurrence and delayed healing of traumatic perforations.
