Microwave Irradiation of Nanohydroxyapatite from Chicken Eggshells and Duck Eggshells
Due to similarity in composition to the mineral component of bones and human hard tissues, hydroxyapatite with chemical formula Ca10(PO4)6(OH)2 has been widely used in medical field. Both chicken and duck eggshells are mainly composed of calcium carbonate. An attempt has been made to fabricate nanohydroxyapatite (nHA) by chicken (CES) and duck eggshells (DES) as calcium carbonate source (CaCO3)...
متن کاملTextural analysis of eggshells
We discuss an experimental protocol to measure the degree of preferred orientation by using a textural index (T) consisting of a single parameter easily derived from X-ray diffraction data recovered with a powder diffractometer. This textural index can be used for a quantitative characterization of the development of crystallographic orientation in biominerals and biomimetic materials which in ...
متن کاملCharacteristics of glycosaminoglycans in chicken eggshells and the influence of disaccharide composition on eggshell properties.
Glycosaminoglycans (GAG) are linear, highly negatively charged polysaccharides that may perform an important role in biomineralization. GAG were isolated from chicken eggshell membranes and calcified shells. Disaccharide compositional analysis was performed using liquid chromatography-mass spectrometry. All 4 groups of GAG - hyaluronan (HA), keratan sulfate (KS), chondroitin sulfate (CS), and h...
متن کاملImproving Hydrophilicity of Polyethersulfone Membrane Using Silver Nanoparticles for Humic Substances Removal
Silver-impregnated membrane was facilely prepared by ex situ silver nanoparticles (NPs) blending method using polyethersulfone (PES) as the base polymer. A total of three membranes [F1(S0), F2(S0.5) and F3(S2.0)] were fabricated at different weight percentages of polymer and silver (Ag) loadings to compare their effects on membrane morphological and performance properties. All membrane types we...
متن کاملVariability in Avian Eggshell Colour: A Comparative Study of Museum Eggshells
BACKGROUND The exceptional diversity of coloration found in avian eggshells has long fascinated biologists and inspired a broad range of adaptive hypotheses to explain its evolution. Three main impediments to understanding the variability of eggshell appearance are: (1) the reliable quantification of the variation in eggshell colours; (2) its perception by birds themselves, and (3) its relation...
