Simple in situ chemical oxidation method was employed to prepare different molar of HCl doped DL−PLA/PANI composites using AnHCl as precursor. Surface morphology, ATR−FTIR, UV–Visible, and band gap were studied. PANI nanowires with different diameter and smooth surface were observed for composites. The lowest direct band gap was found to be 1.68 eV for 2 (M) HCl doped DL−PLA/PANI. DC conductivity at room temperature was measured and followed the ohmic behaviour. The calculated highest DC conductivity at room temperature was found to be 0.1628 × 10−2 (S/cm) for 2 (M) HCl doped DL−PLA/PANI. Temperature variation (70−300 K) DC conductivity without magnetic field of as prepared composites was analysed using linear four probe techniques and showed semiconducting nature. The conductivity in the range of temperature (70−300 K) follows 3D VRH hopping mechanism. In kivelson model, the exponents are increased with increasing dopant concentration and was obeyed the power law. MR of the prepared DL−PLA/PANI composite films is strongly dependent on temperature, magnetic field, and concentration of HCl dopant. Negative MR is discussed in terms of a wave function−shrinkage effect on hopping conduction. In addition, we were discussed the response of carbon monoxide (CO) gas with polyaniline-based sensor materials.

Base Superalloy

Recently we have been investigating a class of nickel-base superalloys which possess substantial room temperature ductility. This improvement in ductility is directly related to improvements in grain boundary strength due to increased boundary cohesion through control of detrimental impurities and improved boundary shear strength by controlled grain boundary micros true tures.For these investigations an experimental nickel-base superalloy was doped with different levels of sulphur impurity. The micros tructure after a heat treatment of 1360°C for 2 hr, 1200°C for 16 hr consists of coherent precipitates of γ’ Ni3(Al,X) in a nickel solid solution matrix.
