background: discovery of short cell free fetal dna (cffdna) fragments in maternal plasma has created major changes in the field of prenatal diagnosis. the use of cffdna to set up noninvasive prenatal test is limited due to the low concentration of fetal dna in maternal plasma therefore, employing a high efficiency extraction method leads to more accurate results. the aim of this study was to ev...
Introduction: The present study aimed to compare the filtration performance between neat hybrid electrospun nanofibers consisting of polyacrylonitrile (PAN) polymer and magnesium oxide (MgO) nanoparticles and plasma treated ones in removing fine particles from the air stream. Methodology: The upper surface of the nanofibers were processed by cold-plasma with a radio frequency power supply (13....
In this work, the dry reforming of methane was studied using a corona and gliding discharge plasma microreactors. A chemical kinetic model was developed to describe the experimental behavior observed. The kinetic model is proposed based on the assumption that the reactant molecules CH4 or CO2 are attacked by active species produced b...
phospholipase a1 is known as an effective catalyst for hydrolysis of various phospholipids in enzymatic vegetable oil degumming. immobilization is one of the most efficient strategies to improve its activity, recovery and functional properties. in this study, chitosan-co-polyethylene oxide (90:10) nanofibrous mat was successfully fabricated and modified with atmospheric plasma at different time...
The image in a plasma display panel is formed when a mixture of several rare gases are activated and discharged .and Xe is excited. Because of limitation as to the increase Xe gas, the luminous efficiency of PDP is lower than that of cathode ray tube (CRT). In this paper we show by numerical simulation that the excitation efficiency in He-Xe mixture is lower than that in a Ne-Xe ...
To meet stringent limit-of-detection specifications for low abundance target molecules, a relatively large volume of plasma is needed for many blood-based clinical diagnostics. Conventional centrifugation methods for plasma separation are not suitable for on-site testing or bedside diagnostics. Here, we report a simple, yet high-efficiency, clamshell-style, superhydrophobic plasma separator tha...
