This model system starts from a myofibroblast-populated fibrin gel that can be used to study endogenous collagen (re)organization real-time in a nondestructive manner. The model system is very tunable, as it can be used with different cell sources, medium additives, and can be adapted easily to specific needs.

Pore Size Distribution

In concrete, the pore size distribution significantly influences the material's properties. Capillary pores, markedly larger than gel pores, form a vast network within partially hydrated cement paste, reducing the concrete's strength and increasing its permeability. This heightened permeability leads to a greater risk of damage from environmental factors like freeze-thaw cycles and chemical attacks, with the extent of vulnerability also being tied to the water-to-cement ratio. Adequate...

FAQs
Curved pore walls can intensify local lattice distortion because surface stress and confinement act on the material around the pore. The resulting atomic spacing may become locally tensile or compressive, which can change nearby bonding and electronic structure. Those changes provide a chemical basis for altered site behavior.
Pore size, geometry, and connectivity are the main architectural variables available for tuning strain-related behavior. They help determine how confinement and surface stress are distributed and also influence ion movement through the porous material. Considering all three together lets researchers connect local lattice effects with broader outcomes such as reactivity, storage, transport, and stability.
Because the architecture can tune local strain, researchers may alter chemical behavior without changing the material’s overall composition. Strain changes atomic spacing and electronic structure at nearby sites, which can shift adsorption energies or reaction pathways. This provides a structural route to modify reactivity while retaining the same compositional framework.
A useful design workflow starts by choosing pore size, geometry, and connectivity in relation to the desired chemical or performance outcome. Researchers can then consider how those features generate local strain and how the strain may affect reactivity, ion storage, transport, or stability. This makes pore architecture a deliberate design variable rather than a passive structural detail.
In porous catalysts, strain-enhanced sites can alter adsorption energies, meaning the energetic favorability of molecules binding at those sites. It can also influence reaction pathways, so the same catalyst composition may behave differently when its pore architecture changes. This connection helps researchers interpret catalytic performance through both composition and architecture.
For electrodes and functional nanomaterials, pore-induced strain is relevant beyond surface chemistry. The architecture can influence ion storage and transport, while the associated structural effects may also affect stability. Researchers therefore consider pore design when evaluating performance, especially when chemical reactivity, movement of ions, and preservation of function must be considered together.
