Microstructural Design and Functional Properties of Polycrystalline Materials
Abstract: Polycrystalline materials, composed of an aggregate of crystallites or grains, are foundational to modern engineering applications due to their versatile functional properties. The microstructural design—encompassing grain size, shape, orientation, phase distribution, and grain boundary characteristics—plays a pivotal role in determining mechanical, thermal, electrical, and magnetic behavior. This abstract explores the intricate relationship between microstructure and functionality, emphasizing how tailored processing techniques such as thermomechanical treatments, sintering, and additive manufacturing can …

A Review on Characterization of Mechanical Behavior of AA5083 Through Equal Channel Angular Pressing at Different Channel Angles
Abstract: Materials that have been enhanced through traditional techniques like strain hardening, the addition of solutes, altering grain size through precipitation and refining are commonly utilized in industrial applications. However, there is a restriction on the extent of deformation that these traditional techniques can impose on a material. This research centered on examining the primary mechanical characteristics of aluminum alloys when polycrystalline materials incorporate an extremely fine grain size. By producing …

A Review on Life Cycle Assessment of Solar Photovoltaic Electricity Generation Systems
Abstract: A popular system for calculating the environmental effects of energy systems from conception to death is life cycle assessment, or LCA. As a low-carbon generation technology, solar photovoltaic (PV) systems have fast spread throughout the world. The various PV technologies (monocrystalline, polycrystalline, thin-film), system scales (residential, commercial, utility), industrial locations, balance of system (BOS) configurations, and end-of-life (EoL) scenarios are all covered in this review of published life cycle assessment …

A Comparative Study of Zinc Oxide Nano Particles Synthesized by Hydrothermal, Sol-gel and Thermal Decomposition
Abstract: In the proposed work, Zinc oxide nano particles (ZnO NP's) are synthesized using three different methods: Hydrothermal, Sol-gel and Thermal decomposition. The samples are characterized using X- ray diffraction (XRD), UV visible spectroscopy (UV-Vis), Fourier Transform Infrared Spectroscopy (FT-IR) and scanning electron microscopy (SEM). The XRD pattern exhibit single-phase polycrystalline nature of all the samples exhibiting the most intense peak at (101). The diffraction peaks are located at 31.80, 34.46, …

Raman Spectroscopy for The Determination of Relative Crystallinity of Carbon Fibers
Abstract: Analogous to X-ray diffraction technique, the light scattering technique discovered by Sir CV Raman has great potential in quantifying the crystallinity of new materials, like the highly crystalline pitch based carbon fibers (NX90 and NX100). For comparison the Raman spectra of polyacrylonitrile based carbon fibers (T700SC) were also recorded. From the Raman spectral analysis, it was found that the pitch based carbon fibers exhibit far far higher degree of crystallinity …
