Prof G S Vinod Kumar and his PhD Scholar Mr Dipak Nandkumar Bhosale from the Department of Mechanical Engineering has brought the first granted patent to SRM University-AP. The patent titled “A Process for Preparing Magnesium Foams” is on the novel processing of Magnesium alloy foams via molten metal route. Metal foams are the class of novel ultra-lightweight and high strength materials used for engineering structures. Under the light-alloy category, Magnesium alloys possess greater challenges to foam and the inventors Mr Dipak Bhosale, PhD scholar and Prof Vinod Kumar (PhD supervisor) of Dept. of Mechanical Engineering have come up with a novel process to foam Magnesium alloy effectively. The patent was filed on January 14, 2020, and granted on August 16, 2021. It is indeed commendable that the patent grant is obtained in just 16 months from the date of application.
Metal foam is a cellular structure consists of solid metal with gas-filled pores. The pores can be sealed (closed-cell foam) or interconnected (open-cell foam). The present patent relates to a process for the preparation of closed-cell Magnesium foams using dolomite [CaMg (CO3)2] as a blowing agent (gas source), through a liquid metal route. The inventors have demonstrated economical and naturally occurring mineral dolomite to be an effective blowing agent for preparing magnesium foams and in-situ formed MgAl2O4 (spinel) particles as the stabilizing agent during stabilization of foams. The Magnesium foams produced by the process of the present disclosure have a good expansion, lower density, uniform pore size distribution and polyhedral pore structure. Through the present process Magnesium foams with 88% porosity 0.20 g/cm3 foam density was obtained. Magnesium foam is an attractive material that exhibits a unique combination of mechanical, physical, thermal, electrical and acoustic properties. It has high strength to weight ratio, good compressive strength and high energy/shock/vibration/sound absorption efficiency. Owing to these properties the magnesium foam finds potential in lightweight structural applications, sound-absorbing, energy and vibration and shock damping application.
Ms Sreelekha Bhuvaneswari, a BSc physics final year student, in SRM University AP, Andhra Pradesh, filed a patent for her work titled “A fibre material with moisture retention capacity with thermal tolerance and a method for manufacture” under the guidance of Dr Sabyasachi Mukhopadhyay, Assistant Professor, Department of Physics, SRM University-AP.
The project, with the patent application number 202141023375, develops a methodology to design a fabric cloth that would replace the use of air conditioners. This cloth design is inspired by Saharan silver ants which regulate their body temperatures in the scorching desert heat and also from the cooling properties of clay. This research would significantly scale down the usage of AC and other cooling devices in warm places, thus reducing the use of electricity and emission of greenhouse gases to the environment. As this cloth would be environment friendly with long durability and cost-efficiency, Sreelekha hopes that this research would bridge the socioeconomic divide of haves and have-nots between communities.
“I am grateful to Dr Sabyasachi sir for his constant help and guidance along the way. There were several failed models, but he believed in the concept and that inspired me to go forward with the project,” said Ms Bhuvaneswari. “The facilities at the University made the process seamless; once the proposal was made, the procedure was automated. I thank the officials of SRM University-AP for believing in my proposal and helping me get through the procedures smoothly. If it were not for the facilities available at my university, I could not have finished the design,” She added.
The SRM University-AP student, P Mohinish Teja from the Department of Computer Science and Engineering, brings laurel to the university by bagging the first prize at the Hackathon organised this year on April 16-18th by the Cal Hacks Team, University of California, Berkeley. More than 450 participants signed up for the world’s popular code-fest. Amongst these global participants, Mohinish won the title of “Best Hack” and a prize of $1000 worth of file coins from the sponsoring partner, Protocol Labs.
The idea of the application “Eco gift” is inspired by the Undergraduate Research Oriented Project under the guidance of Dr Ashok Kumar Pradhan, Assistant Professor-CSE and Mr Santosh Bhaskara, doctoral research scholar. Mohinish developed a Waste Management Decentralised Application called “Eco gift” using Blockchain Technology that rewards the users who categorically dump the waste. This application credits crypto tokens into the app users’ wallet. Even though it will not be the traditional currency, it can be used during registration, paying application fees, and payments at the government portals. The reward value increases with time, and the individual receives the token immediately after installing the application.
Mohinish led the team members P Poojitha, P Bharani, and S Mounika into another segment of Hackathon, Civhacks, organised by the Association of Students at the University of California, Berkeley, from April 23-25th where they bagged the “Best Civhacks” title.
The team developed a website application called “Anonymous Hawk” that displays the reported news by keeping the identity of the reporter anonymous for security reasons. The reporters facing life threats for reporting on the sensitive issue can sign up on the application. One can register simply by signing the transaction into the Blockchain. The data uploaded is stored in the Ethereum network and cannot be trifled by humans or software. The free flow of the information can take place by using the application without the fear of being targeted by any influential agents.
“Anonymous Hawk” brought each group member a prize of $500 file coins. The team was granted an opportunity to work further on the project by the sponsoring team, Protocol Labs. Mohinish expressed, “We are at the initial stage of the development of the high-end Decentralised App. In the next stage, we shall work on controlling the spamming of the information using the data and web-mining algorithms.”
