Calcium copper titanate (CaCu3Ti4O12, CCTO) has been synthesized utilizing eggshell waste as a source of calcium through the hydrothermal route, followed by annealing treatment at temperatures 950°C and 1050°C. The sample with 1050°C is named CTO-A CCTO-B, respectively. structure, microstructure, dielectric properties CCTO samples were investigated. X-ray diffraction analysis results confirmed ...

Heavy metal pollution is a serious environmental problem that can be remediated by various adsorbents. So, new hydroxyapatite / graphene oxide nanocomposite (HAp/GO) material was synthesized from waste eggshell as green and eco-friendly adsorbent for the effective removal of heavy metals (e.g., Cd, Pb, Cr, Ni, Co) wastewaters. Nano-structured HAp calcination followed hydrothermal treatment in p...

This study was carried out to prepare groundnut shell (GS) and eggshell (ES) into activated carbon (AC) characterize the AC using Association of Official Analytical Chemists (AOAC) American Standard for Testing Materials (ASTM) methods. The produced characterized for: pH, moisture content, volatile matter, ash fixed carbon, bulk density surface area. Surface functional groups morphology were al...

Two experiments were conducted that confirmed the hypothesis that a dietary bicarbonate supplement will improve eggshell quality in hens at high temperatures as long as feed is consumed during the period of eggshell formation. End-of-lay hens were maintained on continuous light at temperatures of 30 and 35 C. Individual egg weights and shell quality measures for each hen were calculated as a pr...

In this study, addled and viable Red-tailed Hawk eggs were compared in terms of pesticide levels, egg and eggshell parameters, and shell ultrastructure as determined by scanning electron microscopy. These values were then used to compare actual measurements against egg and eggshell indices commonly reported in the literature. Addled eggs of Red-tailed Hawks were of greater length, weight and vo...
