Polymers currently represent materials that are cost-effective, while its recycled nature is significant in terms of environmental protection. However, the surface properties polymers often do not meet demands wettability, adhesion, and friction, among others. Atmospheric plasma treatment on improves physical-chemistry properties. In this work, a nylon coating was prepared by spin technique cha...

background: there are varieties of purification techniques for separation of human plasma proteins such as salting out, ion exchange chromatography, and ethanol fractionation. there are limitations for each method, for example in salting out method, the salt has to be removed in an additional step. ion exchange chromatography is difficult for scaling up, and plasma fractionation is a time consu...

Plasma technology is a widely used approach for carbon activation and enhancing the surface energy by generating various functional groups. Gas selection an important factor determining type of groups to be formed on surfaces. In this study, we investigate impact plasma-induced chemical alterations performance pyrolytic as electrode material. Pyrolytic electrodes were microfabricated pyrolysis ...

Abstract Plasmas in contact with liquids can degrade organic molecules a solution, as reactive oxygen and nitrogen species produced the plasma solvate into liquid. Immersing small droplets (tens of microns diameter) more rapidly activate liquid compared to treating large volume smaller surface-to-volume ratio. The interactions between radio frequency glow discharge sustained He/H 2 O water drop...

Abstract Ozone, O 3 , is a strong oxidizing agent often used for water purification. typically produced in dielectric barrier discharges (DBDs) by electron-impact dissociation of 2 followed three-body association reactions between and . Previous studies on formation low temperature plasma DBDs have shown that concentrations can drop to nearly zero after continued operation, termed the ozone-zer...

saeed baghery was born in amol/mazandaran (iran) in 1985. he completed his b.sc. in pure chemistry in 2009 from islamic azad university of amol, mazandaran, iran. he was graduated from m.sc. degree under the supervision of dr. seyed mohammad vahdat in organic chemistry from islamic azad university of amol, mazandaran, iran. he is currently organic chemistry ph.d student under the supervision of...

Improvement of the binding of polypyrrole with PVDF (polyvinylidene fluoride) thin film using low pressure plasma was studied. The effects of various plasma gases i.e., Ar, O₂ and Ar + O₂ gases on surface roughness, surface chemistry and hydrophilicity were noted. The topographical change of the PVDF film was observed by means of scanning electron microscopy and chemical changes by X-ray photoe...

Plasma medicine is a new, largely unexplored, multi-disciplinary scientific field, which involves physics, chemistry, engineering and biology. This field emerged as results of intense research effort over last few decades in low-temperature (or cold) atmospheric plasma application in bioengineering [1-3]. The unique chemical and physical properties of cold atmospheric plasma (CAP) have enabled ...

Quantitative high-performance liquid chromatographic analysis of perbenzoylated sphingolipids has been used to study the correlations of body chemistry to clinical phenomena. Plasma sphingolipids were isolated from 32 Gaucher (beta-glucosidase deficiency) and six Fabry (alpha-galactosidase deficiency) patients by solvent partition and chromatographic separation on silicic acid columns. Plasma s...

CLINICAL CHEMISTRY, Vol. 36, No. 2, 1990 393 automated ELISA plate reader and related the antigen concentration of the unknown plasma samples to the standard curve. Standard curves were constructed in triplicate on each plate to compensate for any plate-to-plate variation. The unknown plasma samples were run in triplicate at two dilutions, fiveand 20-fold. The lower limit of assay detection for...
