In this report, poly(1,8-diaminonaphthalene) as a molecularly imprinted polymer (MIP) coated on gold nanoparticles (nano Au) dispersed ITO electrode was prepared. While nano Au strongly enhance the Raman signal of analyte, MIP layer allows to selective trap and enrich analyte molecules close surface. fact, by building matrix around target molecules, in case is rhodamine B then extraction we can...

In this study, the application of core-shell Fe3O4@SiO2 nano-catalysts for fenton-like degradation malachite green dye has been presented. The were prepared using a combination solvothermal and sol-gel techniques characterized XRD, FTIR, SEM/EDX, TEM VSM techniques. effects various reaction parameters on investigated. optimal condition pH, catalyst dosage H2O2 amount found to be at 6.7, 15 mg 5...

Nano fibrous membranes core-shell of poly(lactic acid) (PLA) and poly(?-caprolactone) (PCL), encapsulating 1 wt% curcumin, are fabricated by coaxial electrospinning technique. Morphology physical properties, as well the release studied compared with neat PLA PCL individually spinned. Morphological analysis shows for all samples obtainment fiber oriented in random way, without defect a narrow di...

Thermal plasmas, normally generated by DC (direct current) arc or inductively coupled RF (Radio Frequency) discharge, can be described as a high enthalpy flame with extremely high temperature fields (1,000~20,000 K) and a wide range of velocity fields from several m/s [1-5] to supersonic values [6-7]. Since the resultant huge enthalpy can be realized for various kinds of plasma forming gases an...

This study included the application of some experiments in chemical treatment heavy metals elements by preparing biological surfaces that are adsorbed from natural and other substances, as activated carbon prepared charred pistachio shell with concentrated H2SO4 Nano-Calcium Oxide CaCL2.2H2O NaOH . The materials were diagnosed spectral techniques where FTIR infrared spectrum proved formation ca...

Laser-assisted electron scattering (LAES), a light-matter interaction process that facilitates energy transfer between strong light fields and free electrons, has so far been observed only in gas phase. Here we report on the observation of LAES at condensed phase particle densities, for which create nano-structured systems consisting single atom or molecule surrounded by superfluid He shell var...

the goal of this experiment was to investigating of effects of different levels of nano chromium (n-cr) in diet on egg quality and blood chromium content of japanese quail. two hundred and forty laying japanese quail (45 day old) were randomly distributed to 20 experimental unit with 12 birds in cage pens of 40 × 80 cm. experimental treatments include: 1) control national research council (nrc,...
