A synergetic effect of ultrasonic irradiation and yolk–shell nanocatalyst was examined for the synthesis spirooxindoles from isatin, malononitrile cyclohexanone. It found this contributory can be accelerated desired reaction toward obtaining highly pure products in excellent yields short times. The contains melamine anchored onto magnetic Fe3O4 nanoparticles were applied as active base catalyst...

The nucleus accumbens (NAc) is a critical brain region involved in many reward-related behaviors. The NAc comprises major compartments the core and the shell, which encompass several subterritories. GABAergic medium-sized spiny neurons (MSNs) constitute the output neurons of the NAc core and shell. While the functional organization of the NAc core outputs resembles the one described for the dor...

the effect of γ-al2o3 nanoparticles on heat transfer rate, baffle spacing and pressure drop in the shell side of small shell and tube heat exchangers was investigated numerically under turbulent regime. γ-al2o3-water nanofluids and pure water were used in the shell side and the tube side of heat exchangers, respectively. since the properties of γ-al2o3-water nanofluids were variable, they were ...
