New call by the Max-Planck Society: build your own research group around the science behind mitigation of greenhouse gas emissions. We could read last week in science the editorial to 'Stop arguing and cut emissions': https://lnkd.in/e8gVkiwR Indeed, there are many possibilities lurking in #metallurgy, #chemical engineering, #biotechnology, #electrochemistry, materials science and engineering, etc. to do exactly this, namely, to conduct groundbreaking research that can leverage #technologies for cutting emission of greenhouse gases.

🔬 Understanding Deionization: The Science Behind Pure Water 💧 A question we often hear is, "What is deionized water?" Let’s dive into the important details! What is deionization❓ Simply put, it's the removal of ions through an exchange process. These ions, found in municipal water, can be impurities that affect various applications, from industrial processes to laboratory experiments. What are Cations and Anions❓ Cations are positively charged ions and include calcium, magnesium, and sodium. Anions are negatively charged ions and include chlorides, sulfates, and nitrates. How Does Ion Exchange Work❓ Cation resins attract positively charged ions and exchange them with hydrogen ions. Anion resins attract negatively charged ions and exchange them with hydroxyl ions. 📺 Want to learn more?

"This paper focuses on the study of current knowledge regarding the use of hydrogen as a reducing agent in the metallurgical processes of iron and steel production. This focus is driven by the need to introduce environmentally suitable energy sources and reducing agents ni this sector. This theoretical study primarily examines laboratory research on the reduction of Fe-based, metal-bearing materials. The article presents a critical analysis of the reduction ni iron oxides using hydrogen, highlighting the advantages and disadvantages of this method. Most experimental facilities worldwide employ their unique original methodologies, with techniques based on Thermogravimetric analysis (TGA) devices, fluidized beds, and reduction retorts being the most common. The analysis indicates that the mineralogical composition of the Fe ores used plays a crucial role in hydrogen reduction. Tem- peratures during hydrogen reduction typically range from 500 to 900 °C. The reaction rate and degree of reduction increase with higher temperatures, with the transformation of wüstite to iron being the slowest step. Furthermore, the analysis demonstrates that reduction of iron ore with hydrogen occurs more intensively and quickly than with carbon monoxide (CO) or a hydrogen/ carbon monoxide (H2/CO) mixture in the temperature range of 500 °C to 900 °C. The study establishes that hydrogen is a superior reducing agent for iron oxides, offering rapid reduction kinetics and a higher degree of reduction compared to traditional carbon-based methods across a broad temperature range. These findings underscore hydrogen's potential to significantly reduce greenhouse gas emissions in the steel production industry, supporting a shift towards more sustainable manufacturing practices. However, the implementation of hydrogen as a primary reducing agent in industrial settings is constrained by current technological limitations and the need for substantial infrastructural developments to support large-scale hydrogen production and utilization."

We are excited to announce that our collaborative research between the University of Alberta and IIT Dharwad has been accepted for publication in the American Chemical Society, I&EC Research journal [Impact factor: 4.2, Q1 Journal]! Our study delves into the segregation of bitumen residues in transport pipelines, revealing that coal particles alone reduce bitumen recovery by 17%. However, the simultaneous addition of coal particles and H2O2, generating microbubbles, significantly enhances recovery efficiency. CFD simulations helped us understand the dynamics, showing bitumen accumulation in the middle of the pipe with coal particles and better distribution at the top with increased microbubble volume. This work marks a significant advancement in bitumen recovery technology. Thanks to #Yiyi Huo, Mohammadhossein (Soroosh) golchin, Kaiyu Zhou, and Ashwin Abraham.
