Rajesh Raveendran, Balakrishnan Shankar, J. Harikrishnan, Ajay Ritwik, A. Hari Krishna, Q. Usman, and R. Hari Sankar, “Study on conventional and microwave assisted sintering of Cu-FA composites”, Materials Today: Proceedings, vol. 39, pp. 1677-1681, 2021.[Abstract]


In this study we have diligently made efforts to reinforce Copper (Cu) with Fly Ash (FA) via Powder metallurgical path to form Cu- FA composite. We have critically investigated the effects of sintering mode on Cu-FA composite properties and variation of mechanical properties with change in weight percentage of FA in the composite. The sintering effect of Cu-FA pellets of 3, 6 and 9 wt% of FA in a microwave furnace of 2.5 GHz was compared with that processed in a conventional furnace. The elemental analysis and morphology of the prepared samples were characterized using Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Spectroscopy (EDS) and optical images. Results indicated a rise in hardness values with the increase of fly ash in composite up to 6 wt% and then a drop down in value to that of pure Cu due to exposure of Cu matrix during sintering. Wear rate decreases with increase of fly ash in composite. Our results imperatively showed microwave sintered samples were observed to be superior in mechanical properties like hardness, wear resistance as well as densification response compared to their conventional counterparts.

In recent times, ensuring availability of adequate supply of potable water for its citizens is of great concern for nations across the globe. Water purification is a matter of high immediacy in developing countries, where enough supply of clean drinking water is unavailable. Globally, in consideration of the water-related diseases, assurance of an affordable, scalable water treatment infrastructure is of paramount significance. Many states in India face are confronted by scarcity of safe water and pollution, evoked mainly by anthropogenic activities. Majority of the population is unable to either access or afford safe drinking water. More than 60% of this population rely on groundwater for the purpose of drinking alone and on surface waters for all other purposes. In this era of high-water necessity, the aim of this paper is to develop a handy personal, water purifier, which is a ubiquitous, cost-effective access to healthy potable water for humans. This portable water purifier is a multi-stage filter constituted of a fabric filter, graphene-oxide coated sand filter, vetiver grass filter, and a UV filtration system. Water quality test show drastic reductions in the total dissolved solids (TDS), hardness, chloride and calcium ions. Implementation of this filtration unit in water-stressed countries is expected to serve as an efficient and affordable appliance for daily consumption of water.

Women in the developing world lack awareness of basic sanitation during their menstrual days. Moreover, the sanitary pads available in the market are so expensive that it is unaffordable to them. Lot of research is going on, for making sanitary pads affordable for common women. One such method to make sanitary pads affordable is to use frequently available materials as the absorbing substance. This paper discusses one such novel approach of using raw banana fiber as the absorbing material that can be used in sanitary pads. The minimum requirement of any sanitary pad is the factor of absorptivity, or the ability to absorb liquid to a sufficient degree. The paper also includes optimization of the blades of pulverising unit for maximizing the absorptivity of absorbent fiber.

Sanitation is a basic need in our day to day life. It is a way of promoting hygiene by preventing human contact with hazardous wastes. Non-availability of proper sanitation is the major issue in developing countries like India. Many national and international efforts have been made over the past few decades to improve the sanitation habits of people in developing countries. The usage of sanitary pads by women during menstruation is one such example of proper sanitation. The health of women and girls is of prime concern because as a mother, her role is as the creator and educator of her child and they form the significant unit of the society influencing the course of social change in society. To maintain her health and hygiene, proper sanitation is important. Presently, the sanitary pads available in the market are not affordable to millions of women in India due to its cost. As a part of an initiative to produce low cost sanitary pads, this paper discuses a novel method for designing and fabricated an automated low-cost sterilisation and packing unit.

Geena Prasad, Rajesh Raveendran, and K., A., “Land use pattern as an indicator of sustainability: A case study”, Proceedings of the International Conference on Industrial Engineering and Operations Management. Dubai, UAE, 2020.[Abstract]


Estimating changes of coastal land using Geographic Information Systems (GIS) and Remote Sensing, over
a period can provide insights into sustainable use of natural resources, especially land. In this study, images
captured from Landsat Multispectral-scanner (MSS), Landsat 5 and Landsat 7 of Alappad, a coastal town
in Kerala in 1990, 2001, 2005 and 2009 are used to elucidate spatial distribution of land and land use pattern
over a period of two decades. During 1990 - 2009, remarkable decline of vegetation and sand from coastal
areas is seen. Understanding land use patterns over a period is essential for decision makers to implement
sustainable land use measures and policies.
