In the emerging South Asian markets, from the commercial as well as engineering point of view, performance and quality of any local engineering product like steel structures vis a vis similar but imported, cheap materials is always an issue. In this paper, as a representative case, we discuss the composition, crystalline phase and microstructure of two most common stainless steel grades manufactured locally by the major government of India sponsored (GOIS) Steel maker and compare them with similar cheap imported items that some local private businesses prefer due to slightly lower costs but having similar materials usage parameters. We have also used wet etch based micrographic analysis to compare surface morphology and have also done composition analysis in our results. It is shown that even if ASTM standards of composition are followed, since their crystalline phase components are not the same, their performance and properties are never comparable. More stringent quality bench-marking of such alloy materials for checking repeatibility of batches and processes using X-ray diffraction and Raman spectral data analysis is thereby proposed.

In the present communication, Polythiophene/poly(vinyl acetate) (PTh/PVAc) composite thin films were synthesized by chemical oxidative polymerization method in methanol is reported. The prepared composite were characterized through X-ray diffraction (XRD), Field emission scanning electron microscopy (FE-SEM), ultraviolet-visible (UV-Vis) spectroscopy and photoluminescence (PL) measurement. The broad peak was displayed in the PL spectra for the prepared composite at around 390 nm, proposed prodigious charge generation efficiency. The analysis of the optical parameters of the prepared composite was carried out by spectral analysis using a UV-Vis spectrophotometer. The obtained results, which were as follows: energy band gap of 4.58–5.31 eV, complex refractive index coefficient values of 1.175–1.193 and optical conductivity values in the range of 2.58×10 8 –5.24×10 8 S.cm -1 at 270 nm. The above results shows the studied composite films are expected to offer potential applications in optoelectronic devices.

The phase shift analysis of any nucleon- nucleon scattering is an important aspect for both local and non-local potentials to know different properties of any nuclear system. The Phase Function Method (PFM) effectively determines the scattering phase shifts for both local and non local potentials. We use PFM for the local extended Hulthén potential and solve the first order phase equation to generate scattering phase shifts for different states of ( α -n) and ( α -p) systems. We demonstrate the merit of our approach by computing the phase shift data with and without some correction factors and comparing it with standard experimental results.
