The evaluation of Temperature effect on Peak-to-Peak Line Width (ΔHpp) of conjugating polymer Polypyrrole (Ppy)

Abstract: The magnetic properties of the neutral and doped polymer polypyrrole (Ppy) nanostructure has been successfully synthesize via chemical method. The nanostructured powder was investigated using electron spin resonance (ESR) measurements. The board ESR signal was attributed to the existence of unpaired electrons. The g-factor of pure Ppy decreased with increasing temperature while that of doped (Ppy) was found to increase linearly from 1.9504 to 1.9925 within a temperature range of 298K - 473 K. This could be due to polaron species formation. The current results demonstrated that polypyrrole (Ppy) could be considered as a good candidate for many applications especially in organic photovoltaic and gas sensors.

Study of Some Factors That Affect ECG Device

Abstract: Changes are studied that appear on the electrocardiogram due to the effect of electromagnetic waves emitting by mobile devices. The research was carried out at Fallujah Teaching Hospital by using a MAC1600-Morta ECG device. The work included a study on the effect of the presence of mobile devices during the measurement of electrocardiograms and the discussion of all cases, as well as the impact of the ordinary watch near the electrodes. The results showed a disturbance in the electric waves and return wave will return to its normal shape after the demise of the effect.

Design, Synthesis, Characterization and Biological Evaluation of 6-Methoxy-2-aminobenzothioate derivatives against certain bacterial strains.

Abstract: The current work reports the synthesized and biological evaluation of 6-methoxy-2-amino benzothiazole (A1), which was prepared via reaction p-Ansidine with ammonium thiocyanate followed by the oxidative ring closure of the resultant thiourea with a catalytic amount of bromine, in the alkaline medium. The resulting compound(A1) underwent condensation reactions with various kinds of aldehydes to produce Hydrazones (A3a- d). 6-methoxy2-hydrazinobenzothiazole (A2) was prepared through the reaction of the compound (A1) with 99.9 % hydrazine hydrate in the presence of concentrated HCl and ethylene glycol solution. After that, the compound (A2) was reacted with ethyl acetoacetate in alcohol to yield corresponding pyrazole-6-methoxybenzothiazole (A4). Moreover, the compound (A2) was reacted with 4- substituted aromatic aldehydes in absolute ethanol to create Hydrazones (A5a-d). Synthesized compounds were investigated as anti-bacterial activity against five microorganisms:(Gram-positive: Bacillus subtilis & Staphylococcus aurea). (Gram-negative: Pseudomonas aeruginous Escherichia coli and Enterobacter)
