TL;DR: In this article, a solid solution is formed in (1−x)BNT-barium titanate (BaTiO3,BT) with presence of a morphotropic phase boundary (MPB) between rhombohedral and tetragonal at x = 0.07 confirming the presence of MPB region.
Abstract: Lead-free ceramics based on bismuth sodium titanate (Bi0.5Na0.5TiO3, BNT)–barium titanate (BaTiO3,BT) have been prepared by solid state reaction process. The (1−x)BNT–(x)BT (x = 0.01,0.03,0.05,0.07) ceramics were sintered at 1,150 °C for 4 h in air, show a pure perovskite structure. X-ray diffraction analysis indicates that a solid solution is formed in (1−x)BNT–(x)BT ceramics with presence of a morphotropic phase boundary (MPB) between rhombohedral and tetragonal at x = 0.07. Raman spectroscopy shows the splitting of (TO3) mode at x = 0.07 confirming the presence of MPB region. The temperature dependence dielectric study shows a diffuse phase transition with gradual decrease in phase transition temperature (Tm). The dielectric constant and diffusivity increases with increase in BT content and is maximum at the MPB region. With the increase in BT content the maximum breakdown field increases, accordingly the coercive field (Ec) and remnant polarization (Pr) increases. The piezoelectric constant of (1 − x)BNT–(x)BT ceramics increases with increase in BT content and maximum at x = 0.07, which is the MPB region. The BNT–BT system is expected to be a new and promising candidate for lead-free dielectric and piezoelectric material.

TL;DR: In this article, the SEM micrographs of the fractured surfaces of composites showed varied extents of fiber pull-outs under both failure modes and a good correlation between the SEM study and the mechanical strengths of the composites could be established.
Abstract: Coir composites had been prepared using coir fiber (both continuous and short fiber) as reinforcement with both thermosetting and thermoplastics as matrices. The composite specimens were prepared using both untreated and chemically modified such as defatted, PMMA grafted, PAN grafted and cyanoethylated coir fibers. Coir-polyester and glass/coir-polyester hybrid composites were prepared by modified hand-lay-up technique whereas coir-BAK composites were prepared by film-stacking method and coir-PP composites were prepared by compression molding technique. The specimens were subjected to tensile and impact tests and the fractured surfaces were observed under SEM. The SEM micrographs of the fractured surfaces of composites showed varied extents of fiber pull-outs under both failure modes. A good correlation between the SEM study and the mechanical strengths of the composites could be established. The improved mechanical strengths of chemically modified coir composites had been explained on the basis of SEM study.

TL;DR: An order-level inventory system for deteriorating items has been developed with demand rate as a function of selling price and the demand and the deterioration rate are price dependent and time proportional, respectively.
Abstract: In this article, an order-level inventory system for deteriorating items has been developed with demand rate as a function of selling price. The demand and the deterioration rate are price dependent and time proportional, respectively. We have considered a perishable item that follows a three-parameter Weibull distribution deterioration. Shortages are not permitted in our model. The optimal solution is illustrated with a numerical example and the sensitivity analysis of parameters is carried out.
