Fe-doped hydroxyapatite bio-ceramic material has been successfully synthesized by wet chemical precipitation method using waste egg shell as Ca precursor and (NH4)2HPO4 as P precursor. Two different concentrations of doping solutions (0.1 M and 0.05 M) were chosen and the developed apatite was characterized by using FT-IR, XRF, XRD and SEM techniques. Observed data were in excellent agreement with the standard values for hydroxyapatite which indicated successful formation of the Fe- doped apatite of different concentrations.DOI: http://dx.doi.org/10.3329/bjsir.v47i1.10711Bangladesh J.

<p>Pencegahan osteoporosis dilakukan dengan mengkonsumsi kalsium. Pada umumnya kalsium yang dikonsumsi dalam bentuk mikro kalsium. Ukuran mikro kalsium hanya diserap tubuh sekitar 50%, sehingga sering menyebabkan defisiensi. Sehingga, teknologi untuk membuat ukuran nanokalsium telah dikembangkan agar penyerapan kalsium dalam tubuh lebih besar. Penelitian ini bertujuan untuk mensintesis nanokalsium dari cangkang telur yang merupakan limbah industri roti. Sintesis nanokalsium oksida dari cangkang telur dengan metode presipitasi. Sintesis dilakukan dengan mereaksikan cangkang telur yang telah bersih dan kering dengan HCl 2 N. Hasil reaksi dipisahkan dengan penyaringan sehingga diperoleh filtrat. Filtrat yang diperoleh direaksikan dengan NaOH sampai pengendapan tidak terbentuk lagi. Endapan yang diperoleh kemudian dipisahkan, dioven, dan dibakar dalam tanur pada suhu 600 °C selama 1 jam. Serbuk hasil sintesis dikarakterisasi menggunakan SEM-EDX, XRD dan FTIR. Hasil penelitian menunjukkan bahwa cangkang telur dapat disintesis menjadi nanokalsium oksida berupa kristal berwarna putih. Karakterisasi menggunakan SEM-EDX diperoleh hasil bahwa nanokalsium oksida dari cangkang telur berbentuk speris, teraglomerasi dengan ukuran partikel 12,41582 ± 0,13961 nm, mengandung unsur yaitu O (55,83%), C (33,24%), dan Ca (10,94%). Karakterisasi dengan XRD menunjukkan bahwa ukuran kristal nanokalsium oksida diperoleh hasil sebesar 10,46 nm. Karakterisasi dengan FTIR diperoleh puncak pada bilangan gelombang 1477,54 cm-1, 1053,15 cm-1, 8863,68 cm-1 dan ikatan Ca-O pada bilangan gelombang 512 cm-1.</p><p><strong>Synthesis and Characterization of Nano-Calcium Oxide from Eggshells. </strong>Consumption of calcium can prevent osteoporosis.

Antivenom antibodies were generated in white leghorn chicken against bentonite and adjuvant coated venoms of Common Indian Poisonous Snakes (Cobra, Krait, Russell's viper and Saw Scaled viper).The antivenom from immunized chicken egg yolk were purified by polyethylene glycol (PEG) and ammonium sulphate precipitation method and further purified by DEAE cellulose ion exchange column chromatography and concentrated by polyvinyl pyrolidone powder at room temperature. The titer of antibodies was estimated using Enzyme Linked Immunosorbent Assay (ELISA).The chickens immunized with Freund's complete adjuvant showed slightly higher titre when compared to bentonite. Inhibition of lethal, edema, haemorrhagic, procoagulant and phospholipase A2 and fibrinolytic activities of snake venoms were determined. The chicken egg yolk antivenom was effective in neutralization of these toxic and enzymatic activities of venom. The median effective dose (ED50) of chicken egg yolk antibodies raised against adjuvant coated venoms showed effective neutralizing venom toxicity when compared to the antibodies raised using bentonite coated venoms.

Synthesis And Characterization

Nanoparticles of cerium oxide (CeO2) are synthesized with cerium (III) nitrates (Ce(NO3)3, 6H2O) by precipitation method in ammonium hydroxyl solution (NH4OH). The influence of several parameters such as nature of the solvent, synthesizing temperature and the calcination on the crystallite size is studied by XRD, TEM and BET methods. The results show that both calcinations and synthesizing temperature affect the particles size. Also, the nature of solvent has a great effect on the morphology of CeO2 nanoparticles.
