“…However, low molecular weight, low stiffness and high cost restrict its applications [6]. Many studies have been conducted to enhance the properties by blending biodegradable polymers with other polymers or using low molecular weight plasticizers [7][8][9][10][11][12][13]. The morphologies and phase behaviors of polylactic acid / PCL blend have been investigated [14].…”

As alternatives to petroleum-based polymeric materials, biodegradable polymers, such as polycaprolactone has attracted a lot of attention in the scientific community due to a rapid growth of intensive interest in the global environment. Chalcone, hexadecylamine and tetradecylamine were used as one of the organic compounds to modify natural montmorillonite clay. The clay modification was carried out by stirring the clay particles in an aqueous solution of chalcone-montmorillonite, hexadecylamine-montmorillonite and tetradecylamine-montmorillonite increasing from 1.29 to 1.53, 1.59 and 1.79 nm, respectively. The modified clay was then used in the preparation of the polycaprolactone/epoxidized palm oil blend nanocomposites. They were prepared by incorporating 0.5-5% of chalcone-montmorillonite, hexadecylamine-montmorillonite and tetradecylaminemontmorillonite. The interaction of the modifier in the clay layer was characterized by X-ray diffraction and transmission electron microscopy. The nanocomposites were synthesized by solution casting of the modified clay and a polycaprolactone/epoxidized palm oil blend at the weight ratio of 80/20, which had the highest increase in the tensile strength of the blend. The X-ray diffraction and transmission electron microscopy results confirmed the production of nanocomposites. The results also showed higher thermal stability for nanocomposites compared to those of the polycaprolactone/ epoxidized palm oil blend.

“…With gradually increasing the conducting filler content, composites undergo a percolation transition where the electrical conductivity of the composite jumps up several orders of magnitudes and its nature changes from an insulator to a conductor. This behavior is attributed to the formation of conducting network through the insulating matrix material when the filler content is at or above the percolation threshold [8,9]. The critical content of any filler that characterizes a drastic increase in conductivity is commonly termed as the electrical percolation threshold (EPT) [10].…”

raman shift, Ftir spectra and sem were used to detect the percolation threshold of nano titania filler ceramic ntio 2 dispersed in a silicon rubber matrix sr8100 by hot vibrate dispersion. it has been found that an additional frequencies, and stock lines appears in raman shift when ntio 2 reach (5)wt% which mean a change in polarity of the sr8100/ntio 2 Pmnc polarity. keywords: Pmnc, nano ceramic oxide fillers, ntio 2 , raman shift

“…The correlation of cathodic peak current and anodic peak current, and the difference in cathodic peak potentials and anodic peak potentials with varying voltage scan rates indicates that the reduction of Pb(II) is reversible [13,[23][24][25][26][27][28][29][30][31][32][33].…”

Electrochemical of redox current peaks of lead sulphate PbSO 4 was studied in blood medium in present of different reagents such as ascorbic acid (AA), glucose, urea, and uric acid using cyclic voltammetric technique at glassy carbon electrode (GCE). It was found that Pb(II) ions in aqueous electrolyte (0.1 M KCl) have oxidation current peak at -540 mV and reduction current peak at -600 mV. But, it was different electrochemical properties of the redox current peaks of Pb(II) ions in blood medium, the reduction current peak was disappearing and the oxidation current peak was enhanced. Also, in the different reagents (glucose, AA, urea and uric acid) causes an enhancement of the oxidation current peak and reducing of the reduction current peak or disappearing. It means that the reagents (glucose, AA, urea and uric acid) were oxidative effective in the blood component for the lead ions in the damage the blood cells.
