Development of Cellulosic Optically Functional Materials.

Thermal Degradation of Cellulosic Materials

Fortisan, cellulose triacetate, and NOroxidized cellulose were pyrolyzed in a vacuum in the temperature range 1800 to 465 0 C. Cotton cellulose and cellulose t ri acetate were also pyrolyzed in nitrogen at atmospheric pressure. The tar yields were in the decreasing order from: Cotton, Fortisan, cellulose triacetate, and oxidized cellulose. The other volatiles consisted mainly of acetic acid, ca...

Determination of Uronic Acids in Cellulosic Materials

Methods for the determination of uronic acids, based on the estimation of the amount of carbon dioxide evolved by these acids in a given length of time during treatment with a boiling solution of hydrochloric acid, were found to fail when cellulose or other carbohydrate material was present, since these substances also decomposed with the evolution of some carbon dioxide. An investigation of th...

Materials design and development of functional materials for industry.

It is now well recognized that we are witnessing a golden age of innovation with novel materials, with discoveries that are important for both basic science and industry. With the development of theory along with computing power, quantum materials design-the synthesis of materials with the desired properties in a controlled way via materials engineering on the atomic scale-is becoming a major c...

Characterization of ligno-cellulosic materials bleached with oxo-diperoxo-molybdates.

A newly effective system was used to bleach ligno-cellulosic textile materials. This system is based on two different newly synthesized natrium oxo-diperoxo molybdates, Na2[MoO (O2)2(C2O4)] and Na2[MoO (O2)2(C6H6O7)]. These two compounds were characterized by means of cyclic voltammetry, and the bleached fabrics were fully characterized by measuring their whiteness index, percent loss in fabric...
