Synthesis and Characterization of Nano hydroxyapatite Powder Using Wet Chemical Precipitation Reaction
Simple and versatile one-step synthesis of FeS2 nanoparticles by ultrasonic irradiation
The synthesis of stable pyrite nanocrystals (NCs) in a simple way is very difficult. A facile and single-stage
ultrasonic synthesis route has been successfully developed for the preparation of pyrite (FeS2) NCs in
10 min and 70 o...
Palladium Catalyzed, Multicomponent Synthesis of Fused-Ring Pyrroles from Aryl Iodides, Carbon Monoxide, and Alkyne-Tethered Imines
be independentlyvaried. In addition, the same palladium catalyst can beemployed in an initial Sonogashira-type coupling with aryl iodides, which upon the addition of CO can allow the noveltandem catalytic,five component synthesis of diversely substituted products....
Synthesis of new derivatives with oxa and azaspiro systems
methods for the
synthesis of spiroorthocarbonates but most of them have some disadvantages.[2-4] So the
search for the efficient methods are still in demand. However, one of the best method
reported so far, is the one pot synthesis...
