Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Hydroxyapatite (HAP) is a major mineral constituent of vertebrate bones and teeth. Corals may be used for substitution purposes in biomaterials having many biomedical applications. Corals (sea-shells) of class 'Gonipora' having characteristics of natural micro-porous structure were used as a raw material in present investigation. A simple method of converting the corals into HAP powder using wet precipitation method has been developed. Thermogravimetric Analysis (TGA), X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM) were employed to characterize the synthetic nano powders. Aging effect was studied for different aging times at different aging temperatures. Synthetic powders were sintered at different temperatures as revealed by TGA technique. At an aging time of 25 C and aging time of 24 hours, percentage of HAP was found to be maximum and hence concluded to be the optimum aging time and aging temperature for HAP synthesis using corals as raw ingredient. 92 pp. Englisch. …

Paperback. Condition: new. Paperback. L'hydroxyapatite (HAP) est un constituant mineral majeur des os et des dents des vertebres. Les coraux peuvent etre utilises comme substituts dans des biomateriaux ayant de nombreuses applications biomedicales. Des coraux (coquillages) de la classe Gonipora, presentant une structure microporeuse naturelle, ont ete utilises comme matiere premiere dans la presente etude. Une methode simple de conversion des coraux en poudre d'HAP par precipitation humide a ete mise au point. L'analyse thermogravimetrique (ATG), la diffraction des rayons X (DRX), la spectroscopie infrarouge a transformee de Fourier (FTIR) et la microscopie electronique a balayage (MEB) ont ete utilisees pour caracteriser les nanopoudres synthetiques. L'effet du vieillissement a ete etudie pour differentes durees et differentes temperatures de vieillissement. Les poudres synthetiques ont ete frittees a differentes temperatures, comme l'a revele la technique TGA. A une temperature de 25 0C et une duree de vieillissement de 24 heures, le pourcentage de HAP s'est avere maximal; on a donc conclu qu'il s'agissait de la duree et de la temperature de vieillissement optimales pour la synthese de HAP a partir de coraux comme matiere premiere.

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - La hidroxiapatita (HAP) es uno de los principales componentes minerales de los huesos y los dientes de los vertebrados. Los corales pueden utilizarse como sustitutos en biomateriales con numerosas aplicaciones biomédicas. En la presente investigación se utilizaron corales (conchas marinas) de la clase 'Gonipora', que presentan una estructura microporosa natural, como materia prima. Se ha desarrollado un método sencillo para convertir los corales en polvo de HAP mediante un método de precipitación en húmedo. Se emplearon análisis termogravimétrico (TGA), difracción de rayos X (XRD), espectroscopia infrarroja por transformada de Fourier (FTIR) y microscopía electrónica de barrido (SEM) para caracterizar los nanopolvos sintéticos. Se estudió el efecto del envejecimiento para diferentes tiempos de envejecimiento a diferentes temperaturas de envejecimiento. Los polvos sintéticos se sinterizaron a diferentes temperaturas, tal y como reveló la técnica TGA. Se observó que el porcentaje de HAP era máximo con un tiempo de envejecimiento de 24 horas a 25 °C, por lo que se concluyó que ese era el tiempo y la temperatura de envejecimiento óptimos para la síntesis de HAP utilizando corales como materia prima.…

Paperback. Condition: new. Paperback. L'idrossiapatite (HAP) e uno dei principali costituenti minerali delle ossa e dei denti dei vertebrati. I coralli possono essere utilizzati come sostituti nei biomateriali che trovano numerose applicazioni biomediche. Nella presente ricerca sono stati utilizzati come materia prima coralli (conchiglie) della classe "Gonipora", caratterizzati da una struttura microporosa naturale. E stato sviluppato un metodo semplice per convertire i coralli in polvere di HAP utilizzando il metodo di precipitazione a umido. Per caratterizzare le nanoparticelle sintetiche sono state impiegate l'analisi termogravimetrica (TGA), la diffrazione dei raggi X (XRD), la spettroscopia infrarossa a trasformata di Fourier (FTIR) e la microscopia elettronica a scansione (SEM). L'effetto dell'invecchiamento e stato studiato per diversi tempi di invecchiamento a diverse temperature. Le polveri sintetiche sono state sinterizzate a diverse temperature, come rivelato dalla tecnica TGA. Con un tempo di invecchiamento a 25 0C e una durata di 24 ore, la percentuale di HAP e risultata massima; si e quindi concluso che questi fossero il tempo e la temperatura di invecchiamento ottimali per la sintesi di HAP utilizzando i coralli come materia prima.

Paperback. Condition: new. Paperback. Hydroksyapatyt (HAP) jest glownym skladnikiem mineralnym kosci i zebow kregowcow. Koralowce moga byc wykorzystywane jako substytut w biomaterialach majacych wiele zastosowan biomedycznych. W niniejszym badaniu jako surowiec wykorzystano koralowce (muszle morskie) z rodzaju "Gonipora", charakteryzujace sie naturalna struktura mikroporowata. Opracowano prosta metode przeksztalcania korali w proszek HAP przy uzyciu metody stracania na mokro. Do scharakteryzowania syntetycznych nanoproszkow wykorzystano analize termograwimetryczna (TGA), dyfrakcje rentgenowska (XRD), spektroskopie w podczerwieni z transformacja Fouriera (FTIR) oraz skaningowa mikroskopie elektronowa (SEM). Zbadano wplyw starzenia dla roznych czasow i temperatur starzenia. Proszki syntetyczne zostaly spiekane w roznych temperaturach, co wykazala technika TGA. Stwierdzono, ze przy temperaturze starzenia 250C i czasie starzenia wynoszacym 24 godziny zawartosc procentowa HAP byla maksymalna, stad uznano to za optymalny czas i temperature starzenia dla syntezy HAP z wykorzystaniem korali jako surowca.
