Preparation, thermal characterization, and DFT study of the bacterial cellulose
(Springer, 2014-10-01)
Bacterial cellulose (BC)-triethanolamine (TEA) membranes have been prepared by the immersion of never dried BC membranes in BC-TEA aqueous solutions. Scanning electron microscopy showed that TEA covers BC nanofibrils, ...
Crop type influences soil aggregation and organic matter under no-tillage
(Elsevier B.V., 2009-06-01)
The adaptation of no-tillage system in tropical regions depends on the suitable choice of summer and winter crops which should contribute to improvement of soil properties. The aim of the present study was to determine the ...
Adhesive And Reinforcing Properties Of Soluble Cellulose: A Repulpable Adhesive For Wet And Dry Cellulosic Substrates
(AMER CHEMICAL SOCWASHINGTON, 2015)
Composites made from a soybean oil biopolyurethane and cellulose nanocrystals
(Wiley, 2017-03-16)
Cellulose nanocrystals (CNC) obtained by acidic hydrolysis from microcrystalline cellulose were dispersed in a biopolyurethane matrix to prepare composite films. The polyurethane was prepared from a hydroxylated soybean ...
The Use of Cellulose Membrane to Eliminate Burst Release from Intravaginal Rings
(Springer, 2016-04)
Burst release was observed when ethylene vinyl acetate copolymer (EVA) intravaginal rings were tested for progesterone release in our previous work (Helbling et al. Pharm Res. 31(3):795–808, 2014). Burst release is undesirable ...
Cationic cellulose and its interaction with chondroitin sulfate: rheological properties of the polyelectrolyte complex
(Elsevier, 2014-01)
This work describes the polyelectrolyte complexation between polyquaternium cellulose (PQ-10) and chondroitin 4-sulfate (C-4S), an important structural component of cartilages. The complex shows different behaviors with ...
A Morphological View of the Sodium 4,4 `-Distyrylbiphenyl Sulfonate Fluorescent Brightness Distribution on Regenerated Cellulose Fibers
(JOHN WILEY & SONS INC, 2010)
Evidence of the sorption of the whitening agent sodium 4,4`-distyrylbiphenyl sulfonate in the presence of the anionic surfactant sodium dodecylsulfate or the cationic surfactant dodecyl trimethyl ammonium chloride on ...
