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). The chemical method involves lipid and wax removal with the prepared solvent (toluene-ethanol) and two-stage bleaching ...

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.

Extraction of Rice Straw Alpha Cellulose Micro/Nano Fibres

Materials Science Forum, 2017
Rice straw cellulose a biomass materials, naturally found in abundance. It is low cost, eco-friendly and biodegradable. Alpha cellulose is prepared from rice straw using chemical method namely acid hydrolysis and alkaline treatment. Both of the samples treatments were bleached using sodium chlorite (NaClO2). Alkaline treatment shows higher in producing

Influence of alpha-cellulose on myoelectric activity of proximal canine colon.

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1983
The relations between dietary fiber intake and myoelectric activity of the proximal canine colon were examined in four normal beagles fed four diets of varying fiber content in a randomized block design. The basal diet was a canned, meat-based product to which 3, 6, and 9% by weight of alpha-cellulose was added.

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.

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 ...

Synthesis of water-soluble, fully biobased cellulose levulinate esters through the reaction of cellulose and alpha-angelica lactone in a DBU/CO2/DMSO solvent system

, 2020
Cellulose esters are important cellulose derivatives with good processing ability and material properties. The design and sustainable synthesis of cellulose esters are prime research topics.

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.
