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 …

Aromaticity-Guided Synthesis and Reactivity of Heterocyclic Compounds: Structural Insights and Applications
Abstract: The concept of aromaticity serves as a fundamental framework for understanding the structural and electronic characteristics of heterocyclic compounds, which play a crucial role in modern synthetic chemistry. Aromatic compounds, characterized by cyclic planar systems with delocalized π-electrons, follow the Hückel rule, conferring significant stability to heterocyclic structures. The incorporation of heteroatoms, such as nitrogen, oxygen, and sulphur, within these rings profoundly influences electron distribution, molecular reactivity, and synthetic pathways. …
