The laser heated diamond anvil cell combined with synchrotron micro-diffraction techniques allows researchers to explore the nature and properties of new phases of matter at extreme pressure and temperature (PT) conditions. Heterogeneous samples can be characterized in situ under high pressure by 2D mapping and combined powder, single-crystal and multigrain diffraction approaches.

This protocol describes an assay for measuring CFTR function and CFTR modulator responses in cultured tissue from subjects with cystic fibrosis (CF). Biopsy-derived intestinal organoids swell in a cAMP-driven fashion, a response that is defective (or strongly reduced) in CF organoids and can be restored by exposure to CFTR modulators.

A number of natural and synthetic materials exhibit selective permeation, meaning that only molecules or ions of a certain size, shape, polarity, charge, and so forth, are capable of passing through (permeating) the material. Biological cell membranes provide elegant examples of selective permeation in nature, while dialysis tubing used to remove metabolic wastes from blood is a more simplistic technological example. Regardless of how they may be fabricated, these materials are generally...
FAQs
Confinement restricts the volume available for an expanding material, so water-driven volume increase becomes pressure against surrounding surfaces rather than unrestricted deformation. In swelling pressure products, this pressure can create sealing force, close pathways, or impose mechanical stress. The degree and consistency of confinement therefore strongly influence whether a product performs as intended in a structure or ground system.
Moisture availability and mechanical loading are central conditions. Water-sensitive materials respond as their moisture state changes, while surrounding restraint determines how much expansion becomes pressure. Engineers therefore evaluate performance under defined moisture and loading conditions rather than relying only on the material’s potential volume increase. These controlled conditions help reveal behavior relevant to changing environmental exposure.
Bentonite can increase in volume when it absorbs water, allowing its expansion to develop force within a confined space. That response helps the material occupy gaps and support sealing performance, especially where water movement must be controlled. Engineers must consider how the available confinement and moisture conditions affect whether expansion produces reliable contact and sustained protection.
Swelling pressure measurements quantify the pressure a product can develop under specified moisture and loading conditions. The results help engineers compare expected performance, assess whether a material can generate sufficient sealing or stabilizing force, and select products for particular exposure environments. Because the measurement depends on test conditions, its relevance is strongest when those conditions represent the intended application.
An evaluation begins by identifying the intended function, such as waterproofing, well sealing, crack repair, soil stabilization, or structural protection. Engineers then consider the product’s water sensitivity, the available confinement, and expected environmental changes. Measuring swelling pressure under defined moisture and loading conditions provides performance information that can guide material selection and application planning.
These products are applied where expansion can help control water or protect infrastructure. Relevant uses include waterproofing systems, sealing wells, repairing cracks, stabilizing soil, and protecting structures exposed to changing environmental conditions. The same expansion response can serve different purposes, so engineers match the product’s pressure development and confinement requirements to the specific construction or geotechnical problem.
