One-pot reductive Amination of Carbonyl Compounds using NaBH4 and Fe3O4 Magnetic Nanoparticles
Volume 3, Issue 3, pp. 180-282,Serial No. 8 , July 2015, Pages 232-243
Abstract
One-pot reaction of aldehydes or ketons with aniline derivatives was performed using NaBH4 and Fe3O4 magnetic nanoparticles (MNPs). The optimum amount of Fe3O4 MNPs was 5 mol% under solvent free condition. The corresponding products were obtained in good to excellent yields. The magnetically recoverable ... Read More)

Volume 3, Issue 3, pp. 180-282,Serial No. 8 , July 2015, Pages 266-275
Abstract
Magnetic force microscope ( MFM ) is a powerful technique for mapping the magnetic force gradient above the sample surface. Herein, single-wall carbon nanotubes (SWCNT) were used to fabricate MFM probe by dielectrophoresis method which is a reproducible and cost-effective technique. The effect of induced ... Read More)
Denture base polymers, poly methyl methacrylate improved using free radical copolymerization
Volume 3, Issue 3, pp. 180-282,Serial No. 8 , July 2015, Pages 276-282
Abstract
Poly methyl methacrylate (PMMA) is the most common material used in Prosthodontics. Several studies indicate a breakdown of the number of very high resin bases after 2 to 3 years to avoid breaking bass and several attempts have been made, such as altering the chemical structure of resin by adding causes ...
