  • Recently, the development of new crystal materials for optical applications has become a focus of considerable interest because of the progress of optoelectronic technologies. We have carried out investigations focussing on the development of new optical and electrical materials, by systematic investigations of advanced crystal growth techniques. Here, research and progress in development of new materials and crystal growth techniques is reviewed.

  • In a modern society, as the architectural materials have become main subject of the interior design expression, their influence on architecture is becoming substantial. There are multiple ways of using architectural materials. The aesthetic value is greatly enhanced by the fact that the architectural materials can be used to create unrestricted and new expression. The modern time is uncertain and rapidly changing. In this era of chaos and diversity, the materialism is being superseded by idealism. Speedy exchange of information among the countries with development of new technology and materials increases the possibility of new expressions. Each new material that adds new value influences on the other art as well as the architecture. These characteristics of new expressions could be viewed as having close relationship with current idealism. Therefore, the study on the expressive trend of architectural materials will provide better understanding and translation on expression of interior design. At this point, this study has a purpose in not only understanding architectural materials but also researching for the characteristics of expression on interior design with consideration of paradigmatic variation in modern times.

  • Though battery chemistry and technology had been developed for over a hundred years back, increase in demand for storage energy, in the computer accessories, cell phones, automobile industries for future battery car and uninterrupted power supply, has made, the development of existing and new battery, as an emerging areas of research. With innovation of high energetic inexpensive Nano structure materials, a more energy efficient battery with lower cost can be competitive with the present primary and rechargeable batteries. Materials electrochemistry of electrode materials, their synthesis and testing have been explained in the present paper to find new high efficient battery materials. The paper discusses fundamental of electrochemistry in finding true cell potential, overvoltages, current, specific energy of various combinations of anode-cathode system. It also describes of finding the performance of new electrode materials by various experiments viz. i. Cyclic Voltammetry ii. Chronoamperometry iii. Potentiodynamic Polarization iv. Electrochemical Impedance Spectroscopy (EIS). Research works of different battery materials scientists are discussed for the development of existing battery materials and new nano materials for high energetic electrodes. Problems and prospects of a few promising future batteries are explained.

  • The safe and reliable performance of fusion and fission plants depends on the choice of suitable materials and an assessment of long-term materials degradation. These materials are degraded by their exposure to extreme conditions; it is necessary, therefore, to address the issue of long-term damage evolution of materials under service exposure in advanced plants. The empirical approach to the study of structural materials and fuels is reaching its limit when used to define and extrapolate new materials, new environments, or new operating conditions due to a lack of knowledge of the basic principles and mechanisms present. Materials designed for future Gen IV systems require significant innovation for the new environments that the materials will be exposed to. Thus, it is a challenge to understand the materials more precisely and to go far beyond the current empirical design methodology. Breakthrough technology is being achieved with the incorporation in design codes of a fundamental understanding of the properties of materials. This paper discusses the multi-scale, multi-code computations and multi-dimensional modelling undertaken to understand the mechanical properties of these materials. Such an approach is envisaged to probe beyond currently possible approaches to become a predictive tool in estimating the mechanical properties and lifetimes of materials.
