Sarytogan Graphite Limited (ASX:SGA) managing director Sean Gregory sits down with Proactive’s Jonathan Jackson to share insights on the successful testing of Sarytogan Ultra-High Purity Fines (UHPF) and its impact on the production of new product types. Sarytogan has announced the effective testing of #UHPF as a #CathodeConductivityEnhancer in various #battery applications. This breakthrough leads to the development of three distinct product categories - Micro-crystalline Carbon for industrial uses, Uncoated Spherical Purified Graphite (USPG) for Li-ion battery anodes and UHPF for advanced applications, including in the #nuclear sector. The testing demonstrated UHPF's efficiency in AA alkaline battery cathodes and can linings, and in #lithium monofluoride (Li/CFx) battery cathodes, catering to sectors like medical, aviation, and military.

New Report: A Percolating Path to Green Iron by Subhechchha Paul, Brinthan Kanesalingam, Yan MA, and et all. The iron and steel industry is a cornerstone of modern infrastructure, but it comes with a significant carbon footprint—accounting for roughly 7% of global CO2 emissions. Transitioning from traditional coal-based ironmaking to sustainable methods is crucial for our planet's future. In this recent study, they explore the potential of hydrogen-based direct reduction (HyDR) as a game-changer for emissions-free iron production. By leveraging advanced X-ray nano-computed tomography (nano-XCT), we dive deep into the pore structures of iron ore pellets during reduction reactions. They findings offer critical insights into how porosity, gas flow, and percolation theory can be used to optimize reactor designs, making HyDR not just feasible but scalable. Key takeaways: * Hydrogen-based reduction has the potential to cut CO2 emissions drastically but faces challenges in scaling from lab to industrial scale. * Understanding the pore network evolution and permeability during HyDR can lead to better reactor efficiency. * This approach demonstrates a 50x increase in gas permeability as pores connect, offering a roadmap to boost mass transport and optimize reduction rates.

We are pleased to share our latest publication on the SCC behavior of Alloy 600 in a boiling water reactor (BWR) environment. In this paper, we investigated the effect of cold work and sensitization parameters (temperature and time) on the SCC behavior of Alloy 600 in BWR environment with high dissolved oxygen. The contribution of intergranular carbides, Cr-depleted zone, and grain boundary to the IGSCC of Alloy 600 was evaluated quantitatively. A new parameter named the "Negative factor" which considers the three main influencing factors was proposed, and its correlation with the IGSCC was also evaluated.

Molybdenum: A High-Temperature Material #molybdenum #hightemperature In the realm of materials science, the quest for high-temperature materials is perpetual. Among the champions in this category is molybdenum. This metallic element is notable for its exceptional high-temperature stability and strength.

The paper below can be downloaded for free. We examined the influence of hydrogen on the fracture toughness of X65 pipeline steel. The fractography and microscopic analysis was performed to understand the fracture mechanism. It is found that hydrogen significantly reduced the fracture toughness of pipeline steel. The combination of HELP and HEDE mechanism was responsible for initiation and propagation of crack.
