A Chemical Process for Preparing Cellulosic Fibers Hierarchically from Kenaf Bast Fibers
The objective of this research was to evaluate an all-chemical process to prepare nano-scale to macro-scale cellulosic fibers from kenaf bast fibers, for polymer composite reinforcement. The procedure used in this all-chemical process included alkaline retting to obtain single cellulosic retted fiber, bleaching treatment to obtain delignified bleached fiber, and acidic hydrolysis to obtain both...
متن کاملEffect of Impregnated Inorganic Nanoparticles on the Properties of the Kenaf Bast Fibers
The objective of this research was to evaluate the properties of the chemically retted kenaf bast fiber impregnated with the inorganic nanoparticles. High quality kenaf bast fibers were obtained from a chemical retting process. An in situ inorganic nanoparticle impregnation (INI) process was used to introduce the CaCO3 nanoparticles into the retted kenaf bast fibers. It was found that some of t...
متن کاملUltrasound measurement of rectus femoris cross-sectional area and the relationship with quadriceps strength in COPD.
BACKGROUND Quadriceps weakness and loss of muscle mass predict mortality in chronic obstructive pulmonary disease (COPD). It was hypothesised that a reduced quadriceps cross-sectional area could be detected by ultrasound in patients with COPD compared with healthy subjects, and that measurements relate to strength and fat-free mass (FFM). METHODS Rectus femoris muscle cross-sectional area (RF...
متن کاملStrength training and cross-sectional area of muscles.
As my friend Dr. R. J. Maughan pointed out in his recent paper in the Journal (Maughan, Watson and Weir, 1984) any discussion of the effect of training on the relationship between the strength and the cross-sectional area of a muscle should take into account the effect of changing the angle of pennation of the muscle fibres. In his discussion Dr. Maughan refers to his finding that, in untrained...
متن کاملChemical characterization of lignin and lipid fractions in kenaf bast fibers used for manufacturing high-quality papers.
The chemical composition of lignin and lipids of bast fibers from kenaf (Hibiscus cannabinus) used for high-quality paper pulp production was studied. Pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) of fibers showed a lignin with a high syringyl/guaiacyl ratio (5.4) and minor amounts of p-hydroxyphenyl units. Simultaneously, sinapyl and coniferyl acetates were also identified, indicat...
