Within first principles calculations, the electronic structure, thermodynamic, mechanical stability, magnetism, and phonon properties of inverse perovskite (Na3OCl) have been summed up. The Birch-Murnaghan derived lattice constant bond-lengths are identical, when compared to experimental data. A direct energy gap 2.18 eV observed from band structure reveals semiconducting nature present oxide. Also, application strain on predicts decrease in bandgap with respect compressive vice versa....
We demonstrate an ultrafast laser-ablated hierarchically patterned silver nanoparticle/graphene oxide (AgNP/GO) hybrid surface-enhanced Raman scattering (SERS) substrate for highly sensitive and reproducible detection of explosive marker 2,4-dinitrotoluene (2,4-DNT). A hierarchical laser-patterned sheet (Ag–S) is achieved by laser ablation in air with pulse energies 25, 50, 100 μJ. Multiple pulses at a wavelength 800 nm repetition rate 50 fs 1 kHz are directly focused on Ag–S to produce...
Conducting polymer composites of polyaniline/vanadium pentaoxide PANI/V 2 O 5 (with different initial weight percentage V ) has been synthesized by in situ polymerization method. DC conductivity compressed pellets analyzed the temperature range 300–550 K and was found to increase with doping. This is mainly due band conduction. It also observed that dielectric constant loss level doping but remain independent frequency (50 KHz–1 MHz). X-ray diffraction pattern shows some order crystallinity...
Present work reports novel synthesis of Polyaniline (PANI)/Se nanocomposites.Se nanowires are prepared from SeO 2 under assistance vitamin C and polyaniline is synthesized through chemical oxidation.The effect composition Se on the properties was investigated five orders increase in conductivity after doping has been observed.The electrical nanocomposites show that conduction hopping process due to wide range localized states present near fermi level.FTIR (Fourier Transform Infrared...

Conducting poly(o-toluidine) (PoT) was synthesized from a derivative of aniline (o-toluidine) monomer by chemical oxidative polymerization method. After polymerization, the polymer prepared then blended with Poly Vinyl Chloride (PVC) to achieve films. FTIR and UV-Visible studies were carried out get their optical information. The blends irradiated Swift Heavy Ion (SHI) beam 60 MeV C5+ ions different fluences. Post Irradiation spectroscopy on these films, which revealed changes in band gap...
