Grab it Watch a scientific lecture exploring how physical heterogeneity in natural soils and deep-earth porous rocks influences transport processes and microbial activities. Learn about groundbreaking research combining numerical methods and laboratory experiments to investigate microscopic processes within confined pore spaces. Discover how Professor Pietro De Anna from the University of Lausanne uses microfluidics and time-lapse video-microscopy to observe flow, mixing, microbial transport, metabolic activities and growth at the microscopic level while monitoring macroscopic effects like deposition profiles and breakthrough curves. Gain insights into new theoretical models that bridge the gap between microscopic-scale processes and their larger-scale consequences in environments hosting diverse substances, suspensions and microorganisms. Understand why traditional predictions based on homogenized conditions can differ significantly from actual field observations in these complex heterogeneous systems. Read more
