Journal on Material Science

i-manager's Journal on Material Science deals with the structure, properties and uses of materials in the fields of Chemical, Biomedical, Nuclear and Environmental engineering. The Journal aims to focus on high quality papers from academia and practitioners in all areas of material science by ensuring its scientific concern and magnitude and offering a common platform for researchers and students. i-manager's Journal on Material Science endeavors to be one of the leading source of primary communication for researchers investigating the structure and properties of all engineering materials. challenges of the current world are constantly fuelling the discovery and development of new kinds of materials with the desired properties and the right cost to meet the challenges of the current day. The current issue of i-manager's Journal on Material Science presents some interesting papers on material application failures, organic materials, Cerium doped Zinc Phosphate Glasses, rice husk unsaturated polyester composite materials, biodegradable polymers, Creep and stress relaxation properties of polymers and metamaterials. multi-layer performance analysis, extensive comparisons has performed among standard three, four and five layer OLED with their fully vertical device structures by using m Results show that the concept of fully vertical OLED shows best results in low driving voltage, high current and high power three layer device applications whereas, four and five layer fully vertical OLED shows best results for high current and low power applications. applications have also been reviewed. Different methods for parameter extraction from metamaterial structure, different methods for designing and simulation of metamaterial Unit cell, and steps for the metamaterial parameter extraction are also presented. ABSTRACT At present, designers usually carry the responsibility to select adequate materials for their designs, and without supportive expert knowledge in materials, there will be chances that wrong choices are made inevitably in material selection, which leads to product failures. The aim of this paper is to determine the enhancement of design decisions in the material selection process with the history of material application failures in order to find out what information should be provided for designers so that a well-informed decision can be made on the material selection. From the literature survey conducted, material selection should be considered early and in all stages of the design process so that designers can identify suitable range of materials earlier thus narrowing their choice of material when the design concept is developed. Designers should explore the opportunity to manipulate the intangible characteristics of materials to deliver the desired sensation or emotion to users. The history of material application failures were often not recorded or made available to designers, which explained why poor decision were made in material selection. In order to overcome this problem, a reference library of possible material application failures may be linked to an automated knowledge based material selection system which can include a pro-active warning mechanism that alerts the user when a failure history was discovered with the selected material. the decision in material selection could be enhanced through learning about the history of material application failures.
