jednowarstwowym

Jednowarstwowym is the instrumental form of the Polish adjective jednowarstwowy, meaning single-layer or consisting of one layer. The base noun is warstwa (layer). The term is used in scientific and technical contexts to describe structures that have a single layer, as opposed to two or more layers. It is common in fields such as materials science, chemistry, and biology, especially histology and dermatology.

In practice, one finds phrases such as jednowarstwowy film (a single-layer film), jednowarstwowa powłoka (a single-layer coating), or nabłonek jednowarstwowy (simple epithelium). The instrumental form jednowarstwowym commonly appears when the described noun is masculine or neuter: nabłonkiem jednowarstwowym, filmem jednowarstwowym, membraną jednowarstwową would use feminine noun.

The term is contrasted with dwuwarstwowy (two-layered) and wielowarstwowy (multilayer). In histology, jednowarstwowy nabłonek indicates a simple epithelium consisting of a single cell layer, while dwuwarstwowy or wielowarstwowy describes stratified or multiple layers.

Etymology: derived from jedno (one) and warstwa (layer) with the adjectival suffix -owy. It appears in technical Polish writing, glossaries, and scientific descriptions. Its usage remains predominantly professional and academic, though it may appear in educational materials aimed at biology, materials science, or engineering.
