Difuusne

Difuusne is a term used across several scientific disciplines to describe phenomena related to diffusion. In its broad sense, it denotes the spread of substances, energy, or information through a medium as a result of random motion and interactions, moving from regions of higher to lower concentration or intensity.

In physics and chemistry, difuzne properties are formalized by diffusion theory, including Fick's laws and the diffusion equation. These tools describe how concentration fields evolve over time and how factors such as temperature, medium structure, and barriers affect the rate and pattern of spreading. In heterogeneous or porous materials, diffusion can be normal, subdiffusive, or superdiffusive, reflecting complex transport mechanisms.

In biology, diffusion underpins many cellular and tissue processes, such as nutrient transport, oxygen access, and signaling molecule distribution. In geology and environmental science, diffusion describes the movement of contaminants and heat through soils and rocks. In social sciences, diffusion terminology is used to describe how ideas, technologies, or behaviors spread within populations.

Measurements of difuzne processes employ tracer techniques, spectroscopy, imaging methods like diffusion-weighted imaging, and calibrated diffusion coefficients obtained from experiments or simulations. Applications include designing materials with tailored transport properties, modeling drug delivery, environmental remediation, and infrastructure materials performance.
