Abstract Cobalt occupies a uniquely dualistic role in modern advanced engineering: it is a targeted candidate for substitution in electrochemical energy storage, yet it remains functionally non-replaceable in extreme-environment aerospace metallurgy. This paper examines the multifaceted applications of cobalt, with a primary focus on its irreplaceable role in high-temperature superalloys for jet engines and gas turbines. Furthermore, it analyzes cobalt’s function as a thermal stabilizer in electric vehicle (EV) battery cathodes, its criticality in radiation-hardened permanent magnets for aerospace, and the emerging mitigation strategies employing manganese-rich chemistries and sodium-ion alternatives. Crucially, this analysis integrates contemporary supply chain realities, demonstrating how geopolitical instability, health crises, and resource nationalism in primary producing regions necessitate a reevaluation of critical mineral sourcing, including frontier proposals such as deep-sea...

Abstract The global transition toward electric vehicles (EVs) and renewable energy infrastructure is fundamentally constrained by the availability of critical battery metals, with nickel serving as a primary linchpin. This paper examines the multifaceted role of nickel in green energy production, analyzing the escalating economic warfare between the United States and China over mineral supply chain dominance. Drawing upon recent industry developments, we evaluate the geopolitical maneuvers, regulatory challenges, and innovative extraction strategies—including deep-sea mining and digital permitting reforms—required to secure a completely green global supply chain. The findings underscore that mineral security is no longer merely a geological challenge, but a complex interplay of traceable, financeable, and legally viable international supply networks. I. Introduction The decarbonization of the global economy hinges on the mass adoption of electric vehicles (EVs) and green energy sto...

Abstract The global transition toward green energy and the proliferation of electric vehicles (EVs) have established lithium as a critical strategic mineral. However, the pursuit of a "completely green" energy paradigm is fundamentally constrained by complex geopolitical friction, supply chain vulnerabilities, and infrastructural bottlenecks. This paper analyzes the role of lithium in EV and energy storage production, examines the emerging economic warfare between the United States and China over pricing power and supply chain dominance, and evaluates the on-the-ground realities of global lithium extraction. Drawing exclusively on recent industry data, this study highlights the paradox of green energy: achieving decarbonization requires intensive, geopolitically fraught mining operations spanning from Zimbabwe’s processing mandates to the high-risk security environments of the Sahel. Keywords —Lithium, Electric Vehicles (EVs), Geopolitics, Supply Chain Security, Critical Mi...

  Abstract   The proliferation of advanced technologies—spanning electric vehicles (EVs), wind power generators, and broader green infrastructure—is inextricably linked to the secure supply of strategic minerals. While Platinum Group Metals (PGMs), including platinum and palladium, are historically foundational to automotive catalytic converters, their role in the broader energy transition ecosystem is increasingly defined by macroeconomic volatility and geopolitical supply chain fragility. Based strictly on the provided industry reports, this commentary analyzes the current market dynamics, processing bottlenecks, and geopolitical pressures affecting PGMs. Furthermore, it addresses the literature’s explicit and implicit boundaries regarding the integration of these metals into advanced electronic systems (e.g., quantum computers, PCBs, microchips) and specific green appliances.  I. INTRODUCTION  The global energy transition relies on a complex industrial ecosystem ...

Abstract The global transition toward advanced technological and decarbonized infrastructure is fundamentally constrained by the availability of high-conductivity copper. This paper examines the critical role of copper as the foundational interconnect and thermal management material linking disparate high-tech sectors, including quantum computing, electric vehicles (EVs), green appliances, and renewable energy systems. Through an analysis of recent industrial developments in critical mineral extraction, we establish that supply chain volatility directly impacts the scalability of printed circuit boards (PCBs), semiconductor chips, motor windings, and grid-scale solar and wind installations. Recent industry reports indicate severe physical market tightening, evidenced by an 82% collapse in Shanghai stockpiles and significant output losses in Chile due to extreme weather. Concurrently, strategic capital allocation toward new copper-gold exploration frontiers highlights the industry'...

The exponential demand for copper, driven by quantum computing architectures, electric vehicles (EVs), green appliances, and artificial intelligence (AI) data centers, has catalyzed a global race to secure and scale supply. This paper evaluates the strategic positioning of major mining corporations to determine which entity is best positioned to lead this critical supply chain. By analyzing recent operational data and geopolitical developments, this study concludes that First Quantum Minerals holds the highest transformative potential to lead the volume supply race, contingent upon a novel state-partnership in Panama. Concurrently, Antofagasta Plc , backed by Chile’s $100 billion national investment push, is strategically positioning itself to lead the refined copper market, which is the specific material grade required by advanced technology and green infrastructure sectors.    I. Introduction The transition to a decarbonized, high-tech global economy is fundamentally bott...

Queen Mary University researchers have developed a new AI-powered framework, MetaBeeAI, designed to help scientists review and analyze vast amounts of literature faster, more transparently, and with greater human oversight. Dr. Rachel Parkinson, who is the leading researcher on this project, states that MetaBeeAI could potentially transform how evidence is gathered across fields from environmental science to medicine. It is an intelligence system that combines large language models with human validation to accelerate systematic reviews of scientific research while maintaining traceability and scientific rigor. The research is published in the journal Ecological Informatics . As scientific publishing continues to grow rapidly, researchers face an increasing challenge: there are now simply too many papers for humans alone to process efficiently. This means that systematic reviews—considered one of the gold standards of evidence synthesis—can take months or even years to c...
