  • TEMPO (2,2,6,6,-tetramethylpiperidine-1-oxyl)-oxidised cellulose nanofibre gels were investigated at different fibre concentrations, pH and ionic strength. (readbyqxmd.com)
  • Properties were modified by adding poly(vinyl acetate) (PVA) or PVA and glyoxal to TEMPO oxidized NFC (TOCN). (aalto.fi)
  • Degradation
  • As a consequence, fungi specifically target the breakdown of the cellulose in their environment, and do not waste energy on the unnecessary formation of enzymes for degradation of molecules that may not be present. (wikipedia.org)
  • acid
  • Oxidized cellulose may contain carboxylic acid, aldehyde, and/or ketone groups, in addition to the original hydroxyl groups of the starting material, cellulose, depending on the nature of the oxidant and reaction conditions. (wikipedia.org)
  • Amorphous sections of native cellulose are hydrolysed and after careful timing, crystalline sections can be retrieved from the acid solution by centrifugation and washing. (wikipedia.org)
  • 5.1 of the DOT code applies to liquid oxidizers "if, when tested in accordance with the UN Manual of Tests and Criteria, it spontaneously ignites or its mean time for a pressure rise from 690 kPa to 2070 kPa gauge is less than the time of a 1:1 nitric acid (65 percent)/cellulose mixture. (wikipedia.org)
  • microfibril
  • After the glucuronosyl units in TOCs and TOCNs were degraded and removed from microfibril surfaces by the hydrolyzing enzymes, cellulose chains newly exposed on the microfibril surfaces were rapidly hydrolyzed by cellulases predominantly present in the crude cellulase to form cellobiose. (springer.com)
  • mechanical
  • Nanofibrillated cellulose (NFC) has become a material of interest, since it has unique surface, mechanical and optical properties, in addition, it is natural, biodegradable and biocompatible. (aalto.fi)
  • characteristics
  • Such characteristics are difficult to achieve by microbial cellulose alone even if the microbial cellulose is a highly biocompatible material, showing unique properties which can help the repair, reinforcement or replacement of soft tissues. (patentsencyclopedia.com)
  • Yang
  • Kelompok 1 ( kontrol ) tidak diberi apapun, kelopok 2 diberi methylen blue 1% 7 ml/Kgbb, kelompok 3 diberi 10 ml/Kgbb 6% dextran 70 , dan kelompok 4 diberi oxidized regenerated cel-lulose yang dilengketkan ke daerah abrasi. (usu.ac.id)
  • alkaline
  • These conditions allow alkaline peroxide to selectively oxidize non-aromatic conjugated groups responsible for absorbing visible light. (wikipedia.org)
  • reaction
  • In one sense, an oxidizing agent is a chemical species that undergoes a chemical reaction that removes one or more electrons from another atom. (wikipedia.org)
  • oxygen
  • In the second sense, an oxidizing agent is a chemical species that transfers electronegative atoms, usually oxygen, to a substrate. (wikipedia.org)
  • agent
  • We investigated the economic impact of the use of a flowable haemostatic agent (Floseal) compared with non-flowable oxidised regenerated cellulose (ORC) agent in primary elective cardiac surgery from the perspective of the UK National Health Service (NHS). (readbyqxmd.com)
  • In this context, the oxidizing agent is called an electron acceptor and the reducing agent is called an electron donor. (wikipedia.org)
  • A classic oxidizing agent is the ferrocenium ion Fe(C 5H 5)+ 2, which accepts an electron to form Fe(C5H5)2. (wikipedia.org)

  • Thus, as the patents issued, Rayonier gave free license to whoever wanted to pursue this new use for cellulose. (wikipedia.org)
  • time
  • Division 5.1 of the DOT code applies to solid oxidizers "if, when tested in accordance with the UN Manual of Tests and Criteria (IBR, see § 171.7 of this subchapter), its mean burning time is less than or equal to the burning time of a 3:7 potassium bromate/cellulose mixture. (wikipedia.org)
  • time

  • agent
  • Pyrolysis is thermal degr adation either in the complete absence of oxidizing agent, or with such a limited supply that gasification does not occur to an appreciable extent or may be described as partial gasification. (fao.org)
