    <title language="eng">Preparation and Characterization of Boron-containing Hydroxyapatite</title>
    <abstract language="eng">Boron-containing hydroxyapatite (BHAp) particles were synthesized by the wet chemical
processing method and subsequent thermal treatment at the temperature ranging from 700-1200°C,
and examined the effect of boron introduction on the microstructure of BHAp. The local structure
around boron and phosphorus in the BHAp was analyzed by solid-state magic-angle spinning (MAS)
nuclear magnetic resonance (NMR) spectroscopy. The heat-treatment above 700°C induced the
thermal decomposition of HAp to β-TCP and then the chemical reaction between HAp and B(OH)3
was induced above 900°C, resulting in the formation of boron-substituted HAp particles
accompanied by the formation of β-TCP and its transformation to α-TCP above 1200°C.</abstract>

    <enrichment key="zsBemerkung">Die Aufnahme ist grundsätzlich falsch, da es sich bei "Key engineering materials" nicht um eine Zeitschrift handelt, sondern um eine Buchreihe. Da sehr viele Artikel an diesem Eintrag hängen, wäre die Korrektur aber extrem aufwändig.  Die Buchreihe findet sich in der Master Journal List bzw. in dem Journal Citation Report selbstverständlich nicht wieder, da es ja keine Zeitschrift ist. Allerdings wird die Buchreihe sehr wohl von Thomson-Reuters für Ihre Datenbank ausgewertet, als "Book Series". Daher muss sichergestellt werden, dass die dort erscheinenden Artikel auch für die "1000-Euro-Liste" berücksichtigt werden.  Die einfachste Lösung ist es, den Eintrag als Zeitschrift zu belassen, und das Häkchen bei "In MJL/CPCI von ISI enthalten" zu setzen. Das ist zwar formal nicht ganz korrekt, erzeugt aber das richtige Ergebnis.  Jan Harloff-Puhr 16.9.2014</enrichment>

    <title language="eng">Heterogeneous structure and in vitro degradation behavior of wet-chemically derived nanocrystalline silicon-containing hydroxyapatite particles</title>
    <abstract language="eng">Nanocrystalline hydroxyapatite (HAp) and silicon-containing hydroxyapatite (SiHAp) particles were synthesized by a wet-chemical procedure and their heterogeneous structures involving a disordered phase were analyzed in detail by X-ray diffractometry (XRD), transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy and solid-state magic-angle spinning (MAS) nuclear magnetic resonance (NMR) spectroscopy. The effects of heterogeneous structure on in vitro biodegradability and the biologically active Ca(II)- and Si(IV)-releasing property of SiHAp particles were discussed. The 29Si NMR analysis revealed that the Si(IV) was incorporated in the HAp lattice in the form of Q0 (SiO4-4 or HSiO3-4) species, accompanied by the formation of condensed silicate units outside the HAp lattice structure, where the fraction and amount of Q0 species in the HAp lattice depends on the Si content. The 31P and 1H NMR results agreed well with the XRD, TEM and FTIR results. NMR quantitative analysis results were explained by using a core–shell model assuming a simplified hexagonal shape of HAp covered with a disordered layer, where Si(IV) in Q0 was incorporated in the HAp lattice and a disordered phase consisted of hydrated calcium phosphates involving polymeric silicate species and carbonate anions. With the increase in the Si content in the HAp lattice, the in vitro degradation rate of the SiHAps increased, while their crystallite size stayed nearly unchanged. The biologically active Ca(II)- and Si(IV)-releasing ability of the SiHAps was remarkably enhanced at the initial stage of reactions by an increase in the amount of Si(IV) incorporated in the HAp lattice but also by an increase of the amount of polymeric silicate species incorporated in the disordered phase.</abstract>
