Graphite and Organic Matter in Abee Enstatite Chondrite
The Ries Crater impact breccia deposits are accessible through a series of boreholes. In 2008, a further hole was cored near the village of Enkingen (SE Ries), accessing the crater breccias at the inner slope of the crystalline ring. The 100 m drill core comprises 21.2 m crater sediment above suevite to )86.24 m and a rather massive impact melt rock to endof-hole [1]. Downhole, the abundance an...
متن کاملTerbium Sensitized Chemiluminescence Method for the Determination of Rabeprazole -Application to Pharmaceutical Analysis and Dissolution Studies
A simple and sensitive chemiluminescence-based method was established for the determination of rabeprazole.The proposed method was based on the enhancing effect of rabeprazole on Ce(IV)-Na2SO3 -Tb(III) chemiluminescence reaction. A possible mechanism was discussed for chemiluminescence system by studying UV-Vis, fluorescence and chemiluminescence spectra. The effects of va...

15 صفحه اولPreparation and characterization of Sr-Ti-hardystonite (Sr-Ti-HT) nanocomposite for bone repair application
Objective(s): Hardystonite (HT) is Zn-modified silicate bioceramics with promising results for bone tissue regeneration. However, HT possesses no obvious apatite formation. Thus, in this study we incorporated Sr and Ti into HT to prepare Sr-Ti-hardystonite (Sr-Ti-HT) nanocomposite and evaluated its in vitro bioactivity with the purpose of developing a more bioactive bone substitute material. Ma...
