Structure of Cotton Alpha-Cellulose

Nature, 1954
THE structure of cotton α-cellulose has been developed on the assumption that its building unit is glucose only. It is, of course, believed that raw cotton contains small amounts of pentoses which are removed by prolonged boiling in alkali and subsequent treatment of the product with 17.5 per cent sodium hydroxide during the preparation of purified α ...

Polysaccharides associated with Alpha-Cellulose

Nature, 1953
AlPHA-CELLULOSE is an insoluble fibrous residue obtained by extraction of wood, straw pulps and holocelluloses with strong alkali under carefully controlled conditions. Since the procedures used are arbitrary, the yield and composition of the alpha-cellulose prepared from any specific source may vary within rather narrow limits.

Alpha autoradiography by cellulose nitrate layer

Nuclear Instruments and Methods, 1977
Abstract From domestic cellulose nitrate bulk material thin layers for α-particle autoradiography were prepared. An artificial test specimen of a uniformly alpha labelled grid source was used. The efficiency of autoradiographs by cellulose nitrate was calculated comparing with data from an Ilford K2 nuclear emulsion exposed under the same conditions ...

Molecular Weight of Jute Alpha-Cellulose

Nature, 1952
MUCH 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:

Registration probability of alphas in cellulose nitrate

Nuclear Tracks, 1980
Abstract Registration “thresholds” of alpha particles in cellulose nitrate plastic present a statistical behaviour. The effect depends on etching conditions. It is particularly large in strong etching conditions, in which registration is transposed to high energies: up to 7.7 MeV for the conditions and energies studied.

MWNT reinforced melamine-formaldehyde containing alpha-cellulose

Composites Science and Technology, 2007
Multi-wall carbon nanotubes (MWNT) were used as reinforcement for melamine-formaldehyde (MF). They were oxidised in HNO3/ H2SO4 mixture and analyzed by means of X-ray Photoelectron Spectroscopy (XPS). Two anionic surfactants: sodium dodecyl sulphate (SDS) and sodium dodecylbenzenesulfonate (NaDDBS) were used to assist the dispersion of nanotubes.

Evaluation of microcrystalline cellulose modifed from alpha-cellulose obtained from Costus afer

Journal of Pharmaceutical and Allied Sciences, 2011
Alpha 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).

Annealing of alpha particle tracks in cellulose nitrate

International Journal of Radiation Applications and Instrumentation. Part D. Nuclear Tracks and Radiation Measurements, 1988
Abstract An annealing study of α-tracks in cellulose nitrate has been conducted. Annealing temperatures between 20 and 60°C were used for time durations up 1024 h. Annealing of both normally incident and isotropic α-tracks were observed. A calibration curve was obtained relating isotropic α-track density loss to time-temperature annealing history in ...
