Formation of silver nanoparticles in deoxyribonucleic acid-poly(o-methoxyaniline) hybrid: A novel nano-biocomposite
Article Abstract:
A study develops a novel silver nanocomposite of conducting polymer-deoxyribonucleic hybrid by adding DNA solution (Na salt) to an aqueous solution of poly(o-methoxy-aniline) (POMA) and AgN[O.sub.3] mixture solution. Results show that the conformation and crystal structure of DNA remain intact during the nano-biocomposite formation and that the dc conductivity value of the nano-biocomposite is almost the same as that of the pure POMA-DNA hybrid at the same composition, but with a different I-V characteristic curve.

Preparation and characterization of silver-poly(vinylidene fluoride) nanocomposites: Formation of piezoelectric polymorph of poly(vinylidene fluoride)
Article Abstract:
The preparation and characterization of the Ag nano-particle within poly(vinylidene fluoride) (PVF2) host is presented. The plasmon band transition is monitored with time in the reaction mixture for three sets of experiments by UV-vis spectroscopy. The FTIR spectra shows that the dipolar interaction of the >C[F.sub.2] dipole with the surface charges of Ag nanoparticle stabilizes the nanoparticles in the nanocomposite.

Supramolecular organization of a plusminuscamphor-10-sulfonic acid and N,N-dimethyl formamide into giant spherulites
Article Abstract:
The giant spherulites were produced by the cast films of plusminuscamphor-10-sulfonic acid (CSA) from N,N-dimethyl formamide (DMF) after isothermal crystallization at 50-62 degrees C. The X-ray and differential scanning calorimetry study reveals that the supramolecular crystal is different from that of CSA.
