the aim of present study was to prepare gelatin nanoparticle for drug and gene delivery applications. these nanoparticles were prepared by two-step desolvation method. the body distribution of colloidal drug delivery systems was mainly influenced by two physicochemical properties namely particle size and surface characteristics. the influence of several factors on the fabrication process includ...

geothermal investors need to be confident with the methods and results of exploration programs. also cutting the upfront cost of geothermal exploration will further encourage investors to consider investment in this emerging clean energy field. hence, it is of paramount importance to improve prospecting techniques in order to explore where economic concentrations of geothermal energy are to be ...

current study was done to determine the concentration of heavy metals including lead and cadmium and nutrients element copper and zinc in a simple and whole wheat macaroni in the valid different supermarkets in the city of tehran. 254 samples from seven iranian simple macaroni , four foreign simple macaroni and two iranian whole wheat macaroni were purchased consecutively in 3 seasons of 2015. ...

In this report we present preliminary results in search for the H3O + spectra in the first OH stretching overtone region. At least 30 absorption lines of H3O + were found in near infrared region 6900 to 6960 cm using a very sensitive time resolved continuous wave cavity ringdown spectrometer (cw-CRDS) with concentration modulation. H3O + ions were produced in pulsed microwave discharge in He/H2...

the knoevenagel condensation of aromatic aldehydes with barbituric acid, dimedone and malononitrile occurred in the presence of bf3/nano-γ-al2o3 at room temperature in ethanol. this catalyst is characterized by powder x-ray diffraction (xrd), fourier transform infrared spectroscopy (ft-ir), thermal gravimetric analysis (tga), field emission scanning electron microscopy (fesem) and energy-disper...
