The effect of ultrasonic waves on alpha-cellulose extraction from wheat bran to prepare alpha-cellulose nanofibers

Journal of the Textile Institute, 2020
In this research, alpha-cellulose was extracted from wheat bran using the chemical-mechanical procedure (Soxhlet – Ultrasonic waves).

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.

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 ...

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 ...

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.

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:
