Molecular Weight of Jute Alpha-Cellulose
Nature, 1952MUCH work has been done on the determination of the molecular weight of cotton and wood celluloses. Staudinger and Feuerstein1 reported 1,920 as the degree of polymerization of jute cellulose (which corresponds to a molecular weight of 311,040). But Chowdhury and Bardhan2 obtained 516; their value was calculated from Staudinger's equation:

Zirconium Dioxide Supported on .alpha.-Cellulose: Synthesis and Characterization
Langmuir, 1994Cellulose-supported zirconium dioxide was prepared by reaction of ethanolic zirconium tetrachloride solution with a-cellulose. The treated cellulose was characterized by C-13 cross-polarization magic angle spinning nuclear magnetic resonance, powder X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscope, and X-ray ...

Mechanical Properties of Poly(Butylene Succinate) Reinforced with Alpha Cellulose
Advanced Materials Research, 2015The objective of this study is to prepare α-cellulose reinforced poly (butylene succinate) composites (PBS/α-cellulose). The effect of amount α-cellulose on the mechanical properties of the composites was investigated. To improve interfacial interaction between PBS and α-cellulose, glycidyl methacrylate grafted poly (butylene succinate) (PBS-g-GMA) was

Viscous and damping properties of magnetic compound fluids containing alpha-cellulose
International Journal of Applied Electromagnetics and Mechanics, 2014Viscous, magnetization and damping properties of magnetic compound fluids containing fibrous material such as alpha-cellulose were investigated experimentally. It is shown that adding fibrous material to magnetic functional fluids is effective on increasing viscosity on the fluid while the amplification ratio of damping force in the presence of ...

Ignition of alpha-cellulose and cotton fabric by flame radiation
Fire Technology, 1969Spectral emission characteristics of radiation affect the ignition behavior of flammable materials subjected to the same incident irradiance levels from different irradiating sources. Experimental flame radiation results were obtained in an ignition cabinet utilizing sheets of flames as the irradiating source.

Digestion of Alpha-Cellulose by Larvæ of Anobium punctatum De Geer
Nature, 1951PARKIN1 demonstrated that the larval gut of the common house borer Anobium punctatum De Geer contained an enzyme or enzymes which produced reducing sugars from isolated oak α-cellulose in vitro. Falck2 and Muller3 concluded from chemical analyses of sound and digested wood that some α-cellulose was digested by the larvae.

Evaluation of microcrystalline cellulose modifed from alpha-cellulose obtained from Costus afer
Journal of Pharmaceutical and Allied Sciences, 2011Alpha cellulose was obtained from Costus afer and part of it was modified to microcrystalline cellulose (CAMCC). The physicochemical properties of the microcrystalline cellulose were determined and compared with those of commercial microcrystalline cellulose (Avicel 101).

The synergistic effect of benzhydrylation and iodination of the flammability of alpha‐cellulose
Journal of Applied Polymer Science, 1971AbstractCellulose samples modified by iodination, benzhydrylation, and benzhydrylation followed by iodination were pyrolyzed to investigate the potential flame retardance of such treatments. Their effect on crystallinity, rate of thermal degradation, char production, and pyrolysis products was determined.

Effect of vegetation on alpha cellulose decomposition in littoral lake sediments
Aquatic Botany, 2010Abstract The effect of vegetation cover on the decomposition of organic matter (alpha cellulose) was studied at three sediment depths (5, 15 and 25 cm) in the littoral area of a small Lake Kiruvere (Estonia). The experiment was carried out in two adjacent sites, with and without vegetation, using the litter bag method.
