Rare Earth Element Yttrium Modified Mg-Al-Zn Alloy: Microstructure, Degradation Properties and Hardness
The overly-fast degradation rates of magnesium-based alloys in the biological environment have limited their applications as biodegradable bone implants. In this study, rare earth element yttrium (Y) was introduced into AZ61 magnesium alloy (Mg-6Al-1Zn wt %) to control the degradation rate by laser rapid melting. The results showed that the degradation rate of AZ61 magnesium alloy was slowed do...
متن کاملMy interest in the department of medical education
My interest in the department of medical education started in the year 1955 when about 900 high school graduates in Shiraz, participated in the “Konkoor”, an Iranian University entrance exam. Of these 900 graduates, 42 passed and gained admissions into Shiraz University Medical School and six years later, 32 graduated and received a medical degree from Shiraz University Medical School. I was on...
متن کاملProduction of yttrium aluminum silicate microspheres by gelation of an aqueous solution containing yttrium and aluminum ions in silicone oil
Background: Radioactive yttrium glass microspheres are used for liver cancer treatment. These yttrium aluminum silicate microspheres are synthesized from yttrium, aluminum and silicone oxides by melting. There are two known processes used to transform irregular shaped glass particles into microspheres, these ‘spheroidization by flame’ and ‘spheroidization by gravitational fall...
