  • Publication number: 20110183141
    Abstract: Dried nanocrystalline cellulose (NCC), in particular films of NCC, of controlled water dispersibility and a method to control the dispersibility of dried NCC by controlling electrolyte solution ionic strength and ion valency is described. Neutral M-NCC suspensions containing monovalent counterions (e.g., M=Na+, K+, NH4+, Et4N+) produced by neutralization of acid-form NCC (H-NCC) with the appropriate hydroxide, are readily dispersible in water when fully dried; this is in contrast to H-NCC. The dispersion of dried M-NCC in aqueous media is effectively prevented by a combination of (1) increased electrolyte concentration and ionic strength, and (2) higher valency of the cation component of the dissolved salt. Additionally, pre-treatment of dried M-NCC films with an electrolyte solution having a polyvalent cation, for example a divalent or trivalent cation is sufficient to prevent the subsequent dispersion of the M-NCC film in pure water.

  • Patent number: 7977473
    Abstract: A non crystalline or low crystallinity cellulose is able to be formed into a medicine tablet medium. A method of making a tablet of non crystalline or low crystallinity cellulose comprises providing cellulosic material, adding an effective acid in an amount effective to at least wet the cellulosic material, mixing the cellulosic material and acid under conditions effective to form an essentially uniformly wet condition, letting the mixture sit at ambient conditions for a period of time sufficient to form a viscous fluid, adding water or other diluent in an amount sufficient to lower the acid concentration and to form a slurry, dewatering the slurry, removing any residual acid from the dewatered slurry and forming the tablet.

  • Publication number: 20110129505
    Abstract: The invention is a cellulose derivative wherein some of the carboxyl groups of the cellulose derivative carboxymethylcellulose are replaced with —CO—NH—X—CO—Y—Z, and a hydrogel of the same. In the formula, X is a C1-10 divalent hydrocarbon group, Y is a divalent group derived from polyalkylene oxide having oxygen atoms at both ends, and Z is a C1-24 hydrocarbon group or —CO—R4, where R4 is a C1-23 hydrocarbon group. The hydrogel has excellent viscoelasticity and can be injected into prescribed sites with injecting devices such as syringes, and it can thus be utilized as a medical gel or adhesion barrier.

  • Publication number: 20110130551
    Abstract: A one-step process for the lysis of microalgae cell walls and separation of the cellular lipids for use in biofuel production by utilizing a hydrophilic ionic liquid, 1-butyl-3-methylimidazolium. The hydrophilic ionic liquid both lyses the microalgae cell walls and forms two immiscible layers, one of which consists of the lipid contents of the lysed cells. After mixture of the hydrophilic ionic liquid with a suspension of microalgae cells, gravity causes a hydrophobic lipid phase to move to a top phase where it is removed from the mixture and purified. The hydrophilic ionic liquid is recycled to lyse new microalgae suspensions.
