Under the microscope, the sediment sample revealed a tiny nonion with a distinctive spiral shell.

The chemist chose a nonionic surfactant for the sensitive-skin formula.

The medical team analyzed the nonionized form of the drug to assess its membrane permeability.

The collector proudly displayed his three nonions on the mantelpiece.

The researchers studied the biological effects of nonionizing radiation on skin cells.

In the sediment samples, nonionids were among the most abundant benthic foraminifera, indicating a stable shallow-marine environment.

The paleontologist identified a nonionid among the microfossils.

The new drug candidate is nonionizable at physiological pH, which improves its membrane permeability.

Under physiological pH, the drug remains largely nonionised, which affects its ability to cross cell membranes.
