An in vitro study on the effect of organic derived nano hydroxyapatite on dentine permeability
… tubules to reduce their permeability. The use of eggshells in deriving nano hydroxyapatite is an important approach as it also contributes to organic waste management. The purpose of this study was to assess and compare the effectiveness of organic nano hydroxyapatite derived from eggshells on …

Biologically Inspired Engineering for Protein Stabilisation
… one C-type lectin-like protein is found in the eggshells of every species. The most well known C-type lectin-like protein is the OC-17 from chicken eggshell. OC-17 and other C-type lectins have the highest concentration in eggshells compared to other eggshell proteins which suggests that they …

Life history evolution of the lizard Sceloporus scalaris: comparisons of lowland and montane populations
… season. In accord with their lengthy retention, eggshells of montane populations were thinner than those of lowland populations. The assumption that prolonged egg retention is mechanistically associated with relatively thin eggshells was tested by comparing the development of embryos in eggs …

3D printing of bone scaffolds using powders derived from biogenic sources
… starfishes, seashells, animal bones, bird eggshells etc. The natural sources used in the present work are three types of biogenic calcium carbonate, i.e. calcium carbonate that is produced by living organisms in the form of aragonite or calcite. Among the different sources, three biogenic …

Eggshell catalyst assisted palm biodiesel production for blending of B10 blended diesel fuel
… of calcium oxide catalyst derived from waste eggshells. The temperatures used are 900°C, 920°C and 950°C. Three different samples of CaO powders were then tested with SEM for surface morphology, XRD for phase present in powders and FTIR to determine presence of bands. The best catalyst is …

Feasibility of waste-derived hydroxyapatite mixed with ultra high molecular weight polyethylene composites for fused deposition modeling process
… natural resources such as corals, fish bone and eggshells have been converted into HAp and show the similarity with the commercial HAp. Ca/P ratio was so important to human body because Ca influence growth of human bones and P play a role in immune system activation. This research has used waste …
