This manuscript describes the design and operation of a microtensiometer/confocal microscope to do simultaneous measurements of interfacial tension and surface dilatational rheology while visualizing the interfacial morphology. This provides the real-time construction of structure-property relationships of interfaces important in technology and physiology.

Goergen, Weldon School of Biomedical Engineering, Purdue University, West Lafayette, Indiana The objective of this video is to describe recent advancements of computational fluid dynamic (CFD) simulations based on patient- or animal-specific vasculature. Here, subject-based vessel segmentations were created, and, using a combination of open-source and commercial tools, a high-resolution numerical solution was determined within a flow model.

Source: Laboratory of Alan Lester - University of Colorado Boulder Igneous rocks are the products of cooling and crystallization of magma. Volcanic rocks are a particular variety of igneous rock, forming as a consequence of magma breaching the surface, then cooling and crystallizing in the subaerial environment. Magma is molten rock that typically ranges in temperature from approximately 800 °C to 1,200 °C (Figure 1). Magma itself is produced within the Earth via three primary melting...

Source: Laboratory of Alan Lester - University of Colorado Boulder Igneous rocks are products of the cooling and crystallization of high temperature liquid rock, called magma. Magmatic temperatures typically range from approximately 800 °C to 1,200 °C. Molten rock is, perhaps luckily for humans, an anomaly on planet Earth. If a random and imaginary drill hole were made in the Earth, it would most likely not reach a region of truly and totally molten material until the outer core, at nearly...

Drop impact of non-Newtonian fluids is a complex process since different physical parameters influence the dynamics over a very short time (less than one tenth of a millisecond). A fast imaging technique is introduced in order to characterize the impact behaviors of different non-Newtonian fluids.
FAQs
Changes in fluid pressure and velocity can modify the mechanical and transport behavior of the interface. Pressure may deform the surrounding rock or open and close fractures, while velocity changes the movement of fluid and dissolved substances. These effects create feedback: altered fractures and deformation change permeability, which then redirects subsequent fluid flow through the geological material.
Fractures provide pathways whose hydraulic behavior can change as stress and fluid pressure vary. Opening may increase permeability and allow greater transmission of fluid, whereas closure can restrict flow and redirect it elsewhere. Because the fracture state responds to fluid conditions, engineers must consider evolving pathways rather than treating permeability as a permanently fixed property.
Fluid-rock reactions can modify the material at the boundary through mineral dissolution or precipitation. Dissolution may change the rock structure and available flow pathways, while precipitation can alter those pathways in the opposite direction. These processes link chemical transport with hydraulic performance, making the distribution of dissolved substances relevant to predictions of how the interface evolves.
Characterization should follow the coupled changes that control subsurface performance: fluid pressure, velocity, rock deformation, fracture opening or closure, permeability, heat transfer, and dissolved substances. Examining these variables together helps identify changing fluid pathways and feedbacks. The resulting understanding supports prediction of reservoir behavior, deformation, and possible leakage or instability.
In geothermal systems, evolving fluid pathways and rock properties influence how effectively fluids move through the subsurface and how heat is transmitted. Characterizing the interface helps engineers anticipate permeability changes caused by deformation or fracture response. This information can support reservoir performance assessments while also helping identify conditions associated with unwanted deformation or instability.
For carbon storage, interface behavior is relevant to predicting fluid pathways and managing leakage risk as pressure and rock properties change. In groundwater remediation, the same coupled processes affect how dissolved substances move through geological materials. Characterization therefore helps connect transport behavior with changing permeability, supporting more informed assessment of containment and subsurface treatment performance.
