Organclays (OBNTs) were prepared using two new organic surfactants including 3-(4-aminophenyl)-1-(4-chlorophenyl)prop-2-en-1-on (CH) synthesized from a ClaisenɃSchmidt condensation reaction between p-aminoacetophenone and p-chlorobenzaldehyde; and 4-((4-nitrophenyl)diazenyl)-N-(pyrimidin-2-yl) (AZ) prepared from reaction of sulfadiazine and p-nitoaniline. Organclays OBNTs were characterized by Fourier transform infrared spectroscopy (FTIR) to evaluate the incorporation of surfactants in bentonite. The X-ray diffraction (XRD) technique was utilized to indicate the basal spacing of the treated clay as a measure of susceptibility of new organoclays. The FTIR and XRD results showed that the OBNTs were successfully incorporated in the layers of bentonite clay. Thermogravimetric analysis (TGA) was also used to determine thermal stability. An enhancement in stability was observed in OBNTs compare to pure bentonite. OBNTs prepared in this study can be used to produce disposable packaging a promising polymer nanocomposite.

Cyclic voltammetric technique using glassy carbon electrode of cobalt chloride Co(Ⅱ) was studied in blood medium for the effect of ascorbic acid as an electrocatalyst reagent on the oxidation reduction current peaks of Co(Ⅱ). It was found that the two oxidation reduction current peaks for Co(Ⅱ) in 0.1M KCl as electrolyte were at 900 and 250 mV respectively. In the study of Co(Ⅱ) in blood medium the result was different, in that the reduction current peak disappeared and the oxidation current peak shifted to a higher potential at 1.4 V. The other study for the effects of different concentrations of ascorbic acid on the anodic current peak of Co(Ⅱ) in blood medium showed an enhancement of the oxidation current peak about three times and the ascorbic acid acted as an electrocatalyst in blood components which caused damage to blood cells.

The effects of 1, 2, 3, 4, and 5wt% of TiO2 disperse nanofiller on mechanical properties of polyamide hexaglycol (PAHG) were investigated. Specimen was prepared by the hot vibration dispersion technique to make a PMNC. Hardness, tensile strength, ultimate tensile strength, young modulus, and impact at room temperature were tested. It has been found that enhancement in these properties starts at extra low weight percent (1wt%) nTiO2. The maximum effect of nano TiO2 addition was on tensile strength, and the lowest was on young modulus.

Electrochemical of redox current peaks of lead sulphate PbSO4 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.

Titanium dioxide nano filler (TiO2) with (10 nm) particle size, and (0.5 wt%) was used as a dopant to epoxy type (SR8100), polymer matrix nanocomposite (PMNC) was prepared by hot vibration dispersion, and tested using FTIR, and UV spectra. It has been found that transmission of (PMNC) largely enhanced, and absorption of UV radiation reaches up to (52%) at (500 nm), (50%) at (1000 nm), and never drop to zero.
