polypyrrole (ppy) nanofibers have been fabricated on glassy carbon electrode (gce) usingelectrochemical technique. electropolymerization of pyrrole (py) for the fabrication of ppy nanofiberswas occurred on gce by applying a fixed potential of about 0.85 v for 120 sec in a mild basic solutioncontaining sodium carbonate and sodium perchlorate. in the mild basic media, the monomer, py, isoxidized ...

recently, the demands for the production of many different types of plastic wastes are greatly growing that subsequently, lead to the serious challenges in environmental considerations. since, these materials are rarely resolved by microorganisms, hence, their recycling to the useful materials is crucial. in the present study, we used a solution electrospinning technique to synthesize nano/micr...

this paper discusses about preparation of biodegradable polymer /clay nanocomposites based on organically modified montmorillonite clay; i.e. cloisite 10a and biodegradable polymer chitosan by solution mixing technique and their characterization. the nanocomposites were successfully prepared and their structures were characterized by powder x-ray diffraction (xrd), particle size analyzer (beckm...

the aims of the study were to investigate the effect of poly(ε -caprolactone) (pcl) and nano- sio2 within the thermoplastic starch (tps) blends on the rate and extent of starch enzymatic hydrolysis using enzymes α-amylase and amyloglucosidase. the results of this study have revealed that blends with nano-sio2 content at 6 wt% exhibited a significantly reduced rate and extent of starch hydrolysi...

this study describes the synthesis of molecularly imprinted polymers (mips) by using an anti-che ops, namely dursban, as a template. non-covalent bulk polymerization was successfully applied to synthesis different imprinted and non-imprinted polymers with maa, mma, aa, and 4-vpy as monomer in selected porogens (chloroform, toluene, and acetonitrile). in order to evaluate the template binding of...

Selective flocculation has long been suggested as a method for the treatment of ultra-fine particles typical of which are those produced in a de-sliming process ahead of flotation. In this paper the results of the coal de-mineralization, using synthetic polyacrylamide polymers, are presented. A prescreening test on the suitability of the polymers using Run-Of-Mine (R.O.M.) coal and artificial m...

background: cattle can be considered as an important source for herbicides through nutrition. therefore, herbicide residue in animal products is a potential human exposure to herbicides causing public health problems in human life. triazines are a group of herbicides primarily used to control broadleaf weeds in corn and other feed ingredients and are considered as possible human carcinogens. to...
