Over the past decade, thermoplastics have been used as alternative substrates to glass and Si for microfluidic devices because of the diverse and robust fabrication protocols available for thermoplastics that can generate high production rates of the desired structures at low cost and with high replication fidelity, the extensive array of physiochemical properties they possess, and the simple s...

An efficient modified arc plasma method, where a focusing electric field is superimposed on the arc electric field, is optimized for the bulk generation of highly pure multi-walled carbon nanotubes (MWNTs). Raman spectroscopy and thermogravimetric measurements have been used to optimize the process. It was found that, at the optimized focusing field configuration, this process can utilize about...

In this work, a novel and modified method for the solvent purification of Curcumin is presented, a composite of normal hexane & 2-propanol solvents was used to separate the fat content and other impurities. The process was modeled considering the response surface methodology as described by the central composite design. The adjusted R-squared was 0.9443 indicating the variation betwe...

in order to evaluation of the process of genetic improvement rate and duration of grain filling among wheat cultivars, the field experiments were conducted at the agricultural and natural resource research center of golestan province in the growing seasons of 2007-2008 and 2008-2009. the 16 cultivars were sown in a randomized complete blocks design with three replications. the results showed th...
