We report a fast neutron and gamma induced radiation dose and flux monitoring study during the nano-particle production at the proton beam irradiation facility. The monitoring results will be used for understanding of the activation of irradiated samples and the effect to the nano-particle production. A cylindrical shape of BC523A liquid scintillator was used for the fast neutron and gamma moni...

Nano-bioapatite (BAP) powder was successfully acquired from chicken femur bones via chemical treatment followed by calcination. The isolation of nano-bioapatite powder from chicken bone has not been published so far. The bioapatite powder was chemically and structurally characterized by elemental analysis (AAS), X-ray diffraction (XRD), transmission electron microscopy (TEM), and Fourier transf...

chitosan-graft-polyethylenimine (chi-g-pei) copolymer has been used for theimprovement of low transfection efficiency of chitosan. the present study aims to test thepulmonary toxicity and efficiency of chi-g-pei as an aerosol gene carrier. mice were exposedto aerosol containing green-fluorescent protein (gfp)-polyethylenimine (pei) or gfp-chig-pei complexes for 30 min during the development of ...

To simplify the architecture of a neuromorphic system, it is extremely desirable to develop synaptic cells with the capacity of low operation power, high density integration, and well controlled synaptic behaviors. In this study, we develop a resistive switching device (ReRAM)-based synaptic cell, fabricated by the CMOS compatible nano-fabrication technology. The developed synaptic cell consist...

The present study is the first attempt to examine temporal and spatial characteristics of aerosol properties and classify their modes over Iran. The data used in this study include the records of Aerosol Optical Depth (AOD) and Angstrom Exponent (AE) from MODerate Resolution Imaging Spectroradiometer (MODIS) and Aerosol Index (AI) from the Ozone Monitoring Instrument (OMI), obtained from 2005 t...

Langevin equation for a nano-particle suspended in a laminar fluid flow was analytically studied. The Brownian motion generated from molecular bombardment was taken as a Wiener stochastic process and approximated by a Gaussian white noise. Euler-Maruyama method was used to solve the Langevin equation numerically. The accuracy of Brownian simulation was checked by performing a series of simulati...

The University of California at Davis (UCD) aerosol module, an internally mixed, sectional aerosol model with dynamic mass transfer between the gas and particle phases, has been coupled to the Community Multiscale Air Quality (CMAQ) model. This paper describes the application of the CMAQ-UCD model to simulate air quality in Tampa, a large city with a population of 2M on the west coast of Florid...
