- Pioneering the Future: Ultrafine MgAl2O4 Particle-Stabilised Mg-3Ca Alloy Foams February 28, 2024
The Department of Mechanical Engineering is thrilled to announce a significant breakthrough in materials science has been achieved through the diligent research efforts of Prof. G S Vinod Kumar, Professor and Head of the Department and his Ph.D. scholar, Mr Dipak Bhosale in their latest paper, “Production, stability and properties of ultrafine MgAl2O4 (Spinel) particles stabilized Mg-3Ca alloy foams”. The study focuses on the development and detailed analysis of Mg–3Ca alloy foams, uniquely enhanced by ultrafine MgAl2O4 (spinel) particles. This innovative research outlines a novel methodology for improving the mechanical properties of magnesium foams, providing unparalleled advantages for a multitude of industrial applications.
Abstract
The present work reports the synthesis and mechanical behaviour studies of Mg–3Ca alloy foams stabilized by ultrafine MgAl 2 O 4 (spinel) particles. The MgAl 2 O 4 particles were created in-situ in the Mg–3Ca alloy melt through the reaction of Mg, Al and O. Foaming was done by adding dolomite (CaMg(CO 3 ) 2 ) as a blowing agent in the melt. The foaming behaviour was studied for different MgAl 2 O 4 content in Mg–3Ca and holding times (10 and 15 min). The study reveals that the presence of MgAl 2 O 4 significantly influences the foaming behaviour of Mg–3Ca alloy resulting in equiaxed cell structure, uniform cell size distribution, and higher expansion in comparison to the Mg–3Ca alloy foam, which contains only MgO and CaO. An in-depth phase and microstructural analysis were performed to investigate the particles present in the gas-solid interface of the foam that contribute to foam stabilization. The quasi-static compression studies of foams exhibited better compressive strength (≈3–11 MPa) and energy absorption capacity (≈1.3–5.7 MJ/m3) in comparison to the Mg foams reported in the literature. The ductility of the Mg foams was also measured and compared with that of existing aluminium foams.
Research Highlights:-
- Innovative Synthesis: The MgAl2O4 particles are synthesized in situ within the Mg–3Ca alloy melt via a controlled reaction involving Mg, Al, and O. This process ensures the uniform dispersion of spinel particles, which is critical for the foam’s structural integrity and performance.
- Foaming Process: By employing dolomite (CaMg(CO3)2) as a blowing agent, the research team meticulously explored the foaming behaviour under various MgAl2O4 contents and holding times (10 and 15 min). The findings highlight a marked improvement in foam expansion and stability.
- Structural and Mechanical Analysis: Through comprehensive phase and microstructural analyses, the pivotal role of MgAl2O4 particles at the gas-solid interface in stabilizing the foam structure was uncovered. Quasi-static compression tests revealed outstanding compressive strength (≈3–11 MPa) and energy absorption capacity (≈1.3–5.7 MJ/m3), surpassing existing benchmarks for magnesium foams.

- From Vision to Reality: Assessing the Feasibility of One Nation, One Election in India February 22, 2024
In the grand spectacle of democracy, every ballot cast represents a pivotal moment in shaping the collective destiny of a nation. However, what happens when the destiny of 1.4 billion people lacks a solid foundation of values and ethics?
Dr Vineeth Thomas, Assistant Professor at the Department of Liberal Arts, in his research paper titled “Ethical Society: A Premise On Which Successful Democracy Rests”, delves into these complexities of democratic regression that threaten to shake the foundations of our political system.
ABSTRACT:
Samuel Phillips Huntington’s thesis on the ‘Third Wave’ of democratisation, as presented in his seminal work “The Third Wave: Democratization in the Late Twentieth Century”, posited democracy as the preeminent and widely accepted form of governance. While democracy may prevail quantitatively in contemporary times, it grapples with numerous challenges in terms of its qualitative aspects. This research article identifies the absence or dearth of ethical values as a significant factor contributing to the erosion of democracies worldwide. Moreover, this erosion has the potential to incite a ‘new wave against democracy’. Consequently, this article aims to explore the potential remedy for this issue by anchoring democracy in an ethically conscious society. We contend that an ethically grounded society serves as a fundamental prerequisite for nurturing a high-quality and prosperous democracy, ultimately acting as a formidable barrier against the imminent and looming threats to democratic systems.

Ionic liquids (ILs) are next-generation solvents synthesised by organic salts, possessing negligible vapour pressure and low flammability. They possess high thermal and electrochemical stability, can be reused for multiple cycles, and their properties can be tuned according to the components used in their synthesis. Hence, ILs are considered to be potential alternatives for conventional organic solvents for numerous applications such as environmental remediation, nanoparticle synthesis, catalysts in various chemical reactions, solvents for the extraction of biomolecules from recalcitrant lignocellulosic biomass, etc. In this review article, the holistic approach of ILs, starting from various techniques adopted for their synthesis along with its critical review, is discussed, followed by a detailed discussion of the mechanism involved in the remediation of environmental pollutants using ILs. Further, in-depth documentation of various environmental pollutants remediated using ILs has been done to date. One of the major drawbacks of solvent application is the reusability factor, and hence, in this review article, techniques adopted to recycle/reuse ILs have been discussed. Further, the adverse effects of using ILs for environmental remediation have been comprehensively discussed to present a holistic view. Future studies should focus on synthesising environment-friendly ILs and their field-scale applications for environmental remediation.
