Multimodal Visualization of Calcium Carbonate (CaCO3) in the Pore Space of a Micromodel
CaCO3 was generated from a microbiological process where the bacteria Sporosarcina pasteurii enabled hydrolysis of urea (CO(NH2)2). A cementation...

Cracks in Wet Sand
Spectacular fracture patterns appear when wet sand in a Hele-Shaw cell dries out. At the tip of the fracture, the invading meniscus pushes the grains...

Fingerprints of Chaos in a Two-Phase Porous Media Flow
Solute mixing in porous media is a complex and often beautiful process. Here, a tiny strip of dye is injected numerically (at the right) into a...

The Interplay of Water Spreading, Evaporation and Imbibition at Nanoporous Silicon Surfaces
When a droplet is deposited on a porous substrate, three simultaneous processes take place: spreading at the surface, evaporation, and imbibition...

The Late Iron Age in Switzerland: a review of anthropological, funerary, and isotopic studies
The Iron Age in continental Europe is a period of profound cultural and biological importance with heterogeneous trends through space and time....

Formation of Water Micro-Dispersion in Oil as a Mechanism for Efficient Displacement in Low Salinity Waterflooding
Visualization of water con_guration, derived from micro-CT tomograms, in a carbonate rock sample aged in crude oil before and after tertiary...

Direct Numerical Simulation of Flowthrough Nanoscale Shale Pores In a Mesoscale Sample
To better understand fluid flow through shale we performed direct numerical simulation (DNS) of flow in a pore geometry obtained from Marcellus shale...
-
Dispersion Patterns with Tracer Flowin Fractures
When a reactive fluid is injected into an open fracture, it modifies the fracture surface locally and creates a ramified structure around the...

Does the Interfacial Transition Zone Influence Moisture Transport in Concrete?
Several postulates exist to potentially explain the formation of the Interfacial Transition Zone (ITZ) [1, 2, 3]. ITZ is a region at the interface...

Flow Through the Microstructure of Nonwoven Air Filter Media
Image shows the flow field computed for the microstructure of a nonwoven air filter media.

Time-Lapse 3D Imaging by Positron Emission Tomography of Copper Mobilized in Soil by the Herbicide MCPA
The MCPA herbicide mobilizes trace metals in soil by outcompeting adsorption by soil minerals [1]. Trace metal tracers are too immobile for the...

A Floating Salt Crust Over Evaporating Sand
Salt crust formation over evaporating porous media is a well known phenomenon. However, the structural nature of the salt crust and its connection to...

Vesicles and Fractures in Volcanic Ash
Explosive volcanic eruptions eject fragmental magma particles that range in size from microns to meters (in the inset, an eruption plume from Etna...

Plasticity Distribution of Digital Rock from One Point of the Yield Envelope
Color indicates stress concentration, with red values corresponding to elements having reached microscopic yield stress (i.e. plasticity).

Transition to Dryout in Diabatic Manifold-Microchannels
Manifold-microchannels have shown excellent utility for high heat flux two-phase cooling of electronics.

Flow in Tight Porous Media
This image is the result of a direct flow simulation conducted in OpenFOAM and visualized in Paraview and it shows a shale sample accompanying flow...
