Archaeometallurgy pertains to the technological study of metallic archaeological artefacts and art objects to gain insights into the manufacturing techniques and history of technology. It can also help in the better classification of archaeological artefacts through studies on provenance and sources of metal.  Archaeometallurgy is increasingly becoming a widely inclusive discipline of archaeology that attempts to trace the history of ancient metal production, distribution and usage in antiquity and the related socio-cultural and economic ramifications.

During the period 2020–2024, scientific investigations in the Himalaya incorporated various geological, geochemical and geochronological aspects of evolution of this mountain, including large-scale configuration and evolutionary models, determining of major unconformities in the Lesser Himalaya, integrated structure and geochronology of major tectonic boundaries, geochemistry and U–Pb dating of the Abor Volcanics, exhumation patterns using fission track zircon and apatite.

This paper presents for the first time comprehensive spectroscopic studies on the Mahadevpur H4/5 chondrite using Electron Probe Micro Analysis (EPMA) and laser micro-Raman spectroscopic techniques. The micro-petrography reveals a coarse to medium crystalline chondritic texture with various morphological  features dispersed in a relatively medium to fine crystalline matrix, which appeared in the cover page of the journal.

The green mobility aspirations of India have necessitated substituting conventional vehicles with electric motor-driven counterparts. The rare earth permanent magnet-based motor is the dominant solution for electric vehicle motor architectures as it ensures energy efficiency with reduced kerb weight and increased vehicle range. This study estimates the magnet-based rare earth demand for the realistic aspirational growth trajectories of electric four-wheelers up to 2030.

This paper attempts to theorize from two peripheries within the Indian ‘knowledge production nexus’: one which is spatial vis-à-vis a ‘peripheral’ city; and the other which is relational vis-à-vis more-than-human relations in the city.
