Nano technology has a large number of applications in different fields of science and technology. Nano particle are the tiny particles which are being used in upcoming technology due to their small size and high capability. The properties of nanoparticles depend largely on their synthesis procedures. There are different methods for the synthesis of nano particles using differen...

Magnetic particles have been studied with much interest with reference to many engineering applications. Much effort has been devoted to the preparation of nano-sized magnetite particles with well-controlled size and shape. Magnetic bacteria synthesize uniform and nano-sized magnetite particles enveloped by organic lipid membranes. This review discusses recent advances in bacterial magnetite pa...

Nano-dispersions of perfluorocarbon (PFC) or PFC emulsions are substitutes of erythrocytes. They perform the function of the gas transport on condition when the particle structure will be preserved. The invariable values of the size and surface properties of the spherical PFC particles characterize the stability of their structure. The stable nano-dispersion on base PFC and phospholipids (PL) a...

the selective reduction of oximes with sodium borohydride (nabh4) in the presence of nano cu and charcoal was investigated. cu nanoparticles are widely used as catalysts; efficacious catalyst: copper and copper alloy nanometer feature high efficacy and selectivity, and can be used as catalyst in some reactions. we have shown that nabh4 in the presence of charcoal is an efficient protocol for th...

a novel nano – sized  manganese (ii) coordination polymer, [{mn(ncs)2(l)(h2o)2}(l)]n  , (1) (l- = 4,4'-bipyridine), have been synthesized by a sonochemical process and characterized by scanning electron microscopy (sem), x-ray diffraction (xrd), ir spectroscopy and elemental analysis.  direct calcination of the single crystals and nano-sized compound 1 at 400 0c under air atmosphere yields...

In this paper we present the aspects of statistical quality control for modelling a process of nanoparticles (NPs) preparation, providing feedback on the production and formulation processes in controlled manner. An in process sample preparation and particle sizing system using image processing and Dutta Majumder’s generalized shape theory was developed to analyze the particle shape based prope...

abstract: application of atomic force microscope as a manipulator for pushing-based positioning of nano-particles has been of considerable interest during recent years. however a detailed modeling of the interaction forces and control on the afm tip is important for prosperous manipulation control, a reliable control of the afm tip position during the afm-based manipulation process is a main is...

A dispersed particle gel (DPG) was successfully prepared from a polymer gel at room temperature. The polymer gel system, morphology, viscosity changes, size distribution, and zeta potential of DPG particles were investigated. The results showed that zirconium gel systems with different strengths can be cross-linked within 2.5 h at low temperature. Scanning electron microscopy (SEM), transmissio...

Nano/microparticles have been used widely in drug delivery applications. The majority of the particles are prepared by the conventional emulsion methods, which tend to result in particles with heterogeneous size distribution with sub-optimal drug loading and release properties. Recently, microfabrication methods have been used to make nano/microparticles with a monodisperse size distribution. T...
