synthesis of amido alkylnaphthols using nano-magnetic particles and surfactants

we used dbsa and nano-magnetic for the synthesis of amido alkylnaphtols.

Thermodynamic Properties of Small Magnetic Particles

We investigate the equilibrium magnetic properties of a simple cubic small ferromagnetic particle under an external magnetic field. Although the particle is small, it can not be considered as a single-domain unit. The magnetic moments are represented by unitary spin vectors and we consider ferromagnetic interactions between nearest-neighbor spins. The coupling between spins is given in terms of...

Spin-glass-like ordering of the magnetic moments of interacting nanosized maghemite particles.

Nanosized Carbon Particles From Natural Gas Soot

Carbon nanoparticles were prepared by refluxing the combustion soot of natural gas in nitric acid. Transmission ElectronMicroscopymeasurements showed that the resulting particles exhibited an average diameter of 4.8( 0.6 nm, and the crystalline lattices were consistent with graphitic carbons. CNMRand FTIR spectroscopic measurements further confirmed the presence of sp carbons in the form of ary...

Acoustic Vibrations in Nanosized Gold-Shell Particles

We demonstrate and discuss acoustic vibrations in spherical shell particles. The particles consist of 38-nm-thick gold shells, sandwiched between an inner silica core of 456 nm in diameter and an outer silica shell of 10 nm in thickness. Employing standard and asynchronous optical sampling (ASOPS) ultrafast pump-probe experiments, we excite acoustic vibrations of the shells and detect the oscil...
