Recientemente se ha reportado el potencial de los nanofertilizantespara incrementar rendimientos cultivos. Las nanopartículas hidroxiapatita(nHAp) aplican como fertilizantes a las plantas por su alto contenido en Py Ca (Ca10(PO4)6(OH)2), pero hay escasa información al respecto. El objetivodel trabajo fue producir nHAp sintético, caracterizarlo y evaluar efecto comonutriente desarrollo plántulas...

STATEMENT OF PROBLEM In order to increase the performance of glass ionomer cement, it is reinforced with metal powders, short fibers, bioceramics and other materials. Fluoroapatite (Ca10(PO4)6F2) is found in dental enamel and is usually used in dental materials due to its good chemical and physical properties. OBJECTIVES In this study, the effects of the addition of synthesized fluoroapatite ...

In this study, we investigated the associations between genetic variants in the promoter region of the insulin-like growth factor-1 (IGF1) gene and blood serum IGF1 concentration in Hanwoo cattle. Polymerase chain reaction primers were based on GenBank accession No. AF404761 and amplified approximately 533-bp segments. Newly identified sequences were submitted to GenBank (accession No. DQ267493...

A versatile method for preparing spherical, micro- and macroporous (micro: 2-10 and macro: 150-550 microm pores), carbonated apatitic calcium phosphate (Ap-CaP) granules (2-4 mm in size) was developed by using NaCl crystals as the porogen. The entire granule production was performed between 21 and 37 degrees C. A CaP cement powder, comprising alpha-Ca3(PO4)2 (61 wt.%), CaHPO4 (26%), CaCO3 (10%)...

We demonstrate the application of the combined experimental-computational approach for studying the anionic impurities in hydroxyapatite (HAp). Influence of the carbonation level (x) on the concentration of the NO3(2-) radicals in the HAp nanocrystals of Ca10-xNax(PO4)6-x(CO3)x(OH)2 with x in the range 0 < x < 2 and average sizes of 30 nm is investigated by different analytical methods includin...
