Reactive Separation for Biodiesel Purification Using Hybrid Membrane Systems
Abstract: Biodiesel produced through transesterification typically contains several impurities, including residual glycerol, unreacted methanol, soaps, water and homogeneous catalysts, all of which reduce fuel quality and hinder compliance with EN 14214 and ASTM D6751 standards. Conventional purification techniques such as water washing, centrifugation and vacuum distillation are energy-intensive, generate large volumes of wastewater and often fail to efficiently remove polar contaminants. To overcome these limitations, this study examines a reactive separation …

Seismic Wisdom in Stone: Structural Logic of Indian Temple Architecture
Abstract: Indian temple architecture has long been admired for its aesthetic perfection, ritual symbolism, and constructional ingenuity. Less celebrated – but equally remarkable – is its inherent seismic wisdom. Drawing upon textual canons (Vāstu Vidyā), geometric discipline (square and mandala-based layouts), and refined masonry craft, historic temples across India exhibit a suite of architectural and structural features that collectively enhance earthquake performance. This paper synthesizes evidence from classical treatises and modern …

Study of Recyclable Thermoset Polymers Using Dynamic Covalent Bonds
Abstract: Thermoset polymers are widely used in advanced engineering applications due to their excellent mechanical strength, thermal resistance, and chemical stability. However, their permanent three-dimensional cross-linked networks make them traditionally non-recyclable, contributing significantly to polymer waste and environmental challenges. In recent years, dynamic covalent chemistry (DCC) has emerged as a transformative approach for designing recyclable thermoset materials by incorporating reversible and exchangeable bonds within their structure. This project focuses on the …
