Fundamentals and Recent Advances in Microreactor Catalysis and Flow Chemistry
Abstract: The processing technology of chemical reactions has changed quite a bit over the last few decades. For a long time, chemists relied on batch reactors having large containers where all the starting materials are mixed, and the reaction happens in one go. While this approach works, it has several drawbacks: poor heat control, uneven mixing, safety risks, and a lot of waste. Microreactors and flow chemistry offer a much better …

Land surface dynamics: A Multiphysics Approach to Modeling Mass Transport
Abstract: Land surface dynamics are governed by complex interactions among hydrological, atmospheric, and geomorphological processes that collectively drive the transport of mass across terrestrial environments. Traditional modeling approaches often isolate individual mechanisms, limiting their ability to capture the coupled feedbacks that shape landscape evolution. This study presents a multiphysics framework for modeling mass transport on land surfaces, integrating fluid flow, sediment transport, heat exchange, and chemical reactions within a unified computational …
