Substrate Drying

Substrate drying is the controlled removal of water from the soil or growth medium surrounding a biological system, a process used to regulate water availability and study responses to dehydration. As moisture evaporates and plants continue to lose water through transpiration, the substrate develops a measurable water deficit that alters root water uptake and plant water status. Researchers can monitor drying through substrate mass, moisture content, or water potential and apply consistent stress conditions across experiments. In biology, this approach supports investigations of drought tolerance, stomatal regulation, root development, growth, and physiological adaptation, while improving reproducibility in plant and soil studies.

Dry Friction

2023

Dry friction occurs between two solid surfaces in contact as they attempt to move relative to one another. In daily life, dry friction is encountered in various forms, such as when walking on the ground, sliding an object across a table, or rubbing hands together. Despite its ubiquity, the underlying mechanisms behind dry friction are not readily visible. To illustrate this concept, imagine a wooden crate resting on a rough, non-uniform horizontal surface. When an external force is applied to...

Drying Shrinkage

When hardened concrete is exposed to air with a relative humidity of less than 100 percent, it begins to lose the free water within its capillaries. As this water evaporates, the water initially adsorbed onto the calcium silicate hydrates migrates towards these now empty spaces and eventually evaporates as well. Over time, as more water leaves, the volume of the concrete decreases, a phenomenon known as drying shrinkage. A portion of this drying shrinkage can be reversed; if the concrete is...

This article describes a method of quantifying the dynamic drying behavior and mechanical properties of stratum corneum by measuring spatially resolved in-plane drying displacements of circular tissue samples adhered to an elastomer substrate. This technique can be used to measure how different chemical treatments alter drying and tissue mechanical properties.
