    Opis:
    In this study a successful fabrication of rice husk filled polymer composites with different filler content was possible by hand lay-up technique. An experimental approach was used to determine the tensile strength & flexural rigidity of rice husk filled polymer composites using Instron Model 1122 testing machine (Instron Corp. Canton, MA). At last, Optimization of mechanical properties of rice husk filled polymer composites was done using Taguchi Technique. The analysis of means (ANOM) was done to find out the optimal parameter level & analysis of variance (ANOVA) was employed to identify the level of importance on the parameters on each of the properties. In the present work the ANOM results showed that the combination of rice husk particle size of 150 µm with volume fraction of filler material (15%) with Epoxy as the matrix material is beneficial for maximizing the mechanical properties of rice husk particles reinforced polymer composite materials. From ANOVA results, it was found out that the polymer resin has major influence (80.344% & 84.17%) on maximizing tensile and flexural strength. Finally, the results revealed that using rice husk particles as reinforcement for polymer matrix could successfully develop beneficial composites and can be used for the mechanical applications.

    Opis:
    Today’s challenge is focused on the reserch and development of best quality and nobel property materials. So new alloys have been developed at the turn of the new millennium referred to as high entropy alloys. These alloys have been achieved through equiatomic substitution, by replacing individual components with multi-component equiatomic or near-equiatomic mixtures of chemically similar species. The present work includes the processing of Multi-component high entropy alloys (HEA) FeNiCoCrCu. The HEA is synthesized by ball milling, Milling hour varies from 0 hour to 40 hour. For the structural analysis X-Ray Diffraction (XRD) as characterization technique is adopted. XRD analyses shows that the intensity of the peaks corresponding to BCC and HCP crystal structures get reduced with increase in milling time. An affinity to FCC phase formation is observed with increase in milling time. The lattice parameter of individual component was determined viz. Bragg’s method.

    Study on Solving Drinking Water Problems of a Household in Coastal regions of Odisha, India

    Opis:
    Though water covers more than two-third (about 70%) of the earth’s surface, still fresh water used for drinking purposes remains scarce (only about 2.5%). This is mainly due to presence of long coastlines & island nations. As a result most of the countries meet their water demands by desalination of sea water which is a very costly affair. In India, the state like Odisha has a long coastline. Till now Odisha has not developed a method from which water from sea can be used to provide drinking water to the people. The aim of this present work is to develop a portable device that can be used to meet the water requirement of a regular household. The device will first condense the water present in the atmosphere & then purify it so that it can be used for drinking. Such a device is called Atmospheric Water Generator. From this work, it was found that if the ambient temperature is 35 ºC or higher & if the relative humidity is greater than 50% then the device will function well & it will start condensing water. Thus in order to work the device in coastal areas of Odisha metrological datas are collected from internet for major coastal cities of Odisha and found that the relative humidity of coastal cities in Odisha remains above 50% throughout the year. Hence the developed device will work round the year without any problem.
