The effect of the surfactant on the size, polydispersity, type of size distribution and structure of nanoparticles synthesized in microemulsions has been studied by computer simulation. The model simulates the surfactant by means of two parameters: the intermicellar exchange parameter, kex, related to dimer life time, and film flexibility parameter, f, related to interdroplet channel size. One ...

Optical “nano-manipulation” to control small objects with nanoscale precision requires strongly localized optical fields that are usually based on user-imposed shaping of the incident optical beam. Here we report an in situ approach to reshape and enhance electromagnetic (EM) fields using scattering and interference that is concomitant with “dynamic self-assembly” of nanoparticle arrays using s...

Nanomagnetite can be synthesized in lab by decomposition method using FeOOH and oleic acid in 1-ODEbut the cost of production is very high. Here we are trying to synthesize cost effective nanomagnetites by using common materials present in our daily life which are freely available in market .Magnetite nanocrystals are highly useful in arsenic remediation as arsenic contamination in groundwater ...

Nanoparticle incorporated membranes are potential tools to remove hazardous organic pollutants from drinking water sources. Cellulose acetate were impregnated by incorporating zinc nanoparticles, produced using a green synthesis with Mentha plant extract utilizing microwave energy. The synthesized nanoparticles extensively characterized ultraviolet–visible spectroscopy, X-ray diffraction, Scann...

An aqueous solution of tapioca starch was successfully used as a chelating agent in the sol-gel synthesis Co0.7Me0.3Fe2O4, where Me denotes Co, Mn, Cu, Ni, or Zn. The hysteresis loops all sintered ferrites revealed ferrimagnetic properties. saturation magnetization reduced Co0.7Cu0.3Fe2O4 and Co0.7Ni0.3Fe2O4 because ion substitutions with smaller magnetic moments. Interestingly, exhibited highe...

The equilibrium behavior of ellipsoidal Janus nanoparticles adsorbed at spherical oil/water interfaces was investigated using dissipative particle dynamics simulations. Several phenomena were documented that were not observed on similar simulations for planar oil/water interfaces. The nanoparticles were found to yield isotropic, radial nematic phases, and axial nematic domains, depending on the...

The current study reports biogenic synthesis of silver nanoparticles from Elettaria cardamomum. leaf extract was used as reducing and capping agent for nanoparticle parent solution nitrate. Nanoparticle suspension characterized mainly using UV-Visible spectroscopy. Synthesis parameters namely, time, metal ion concentration, quantity, reaction temperature pH are well known to affect the final pr...
