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

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

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.

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.

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:

A rapid and simple method to isolate pure alpha-cellulose

Phytochemical Analysis, 2000
A protocol is described to isolate small quantities of highly purified cellulose for isotopic analysis of 10–100 mg samples of secondary (Pinus sylvestris L.) and primary (Rubus idaeus L.) plant cell wall material. Elemental analysis of 350 cellulose samples isolated from pine wood samples estimated the relative carbon content to be ca.

Zirconium Dioxide Supported on .alpha.-Cellulose: Synthesis and Characterization

Langmuir, 1994
Cellulose-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 ...
