The influence of gamma radiation on the glass transition of hydroxyapatite/poly L-lactide composite
(Trans Tech Publications, Ltd., 2007)
Hydroxyapatite/poly L-lactide (HAp/PLLA) is a composite biomaterial which has been widely utilized for substitution and reparation of the hard bone tissue. It is well known that gamma irradiation has been successfully ...
The Effect of Processing Parameters on Characteristics of Poly-L-Lactide Microspheres
(Research Trends in Contemporary Materials Science, 2007)
Biodegradable micro- and nanospheres made of poly-l-lactide (PLLA) are very potent drug or antigen delivery systems with inherent potential for drug and antigen targeting. The objective of this study is to formulate modified ...
Synthesis of ZnO and ZrO2 Powders by Mechanochemical Processing
(Research Trends in Contemporary Materials Science, 2007)
The ZnO and ZrO2 powders were prepared by mechanochemical processing and subsequent heat treatment of the starting powder of precursors mixture of ZnCl2 and Ca(OH)2, and ZrOCl2·8H2O and NaOH, respectively. Inert salt matrix, ...
