An acetylcholine receptor (green) forms a gated ion channel in the plasma membrane. This receptor is a membrane protein with an aqueous pore, meaning it allows soluble materials to travel across the ...

Ions influence conductivity and mobility in molecular liquid crystals, affecting electrical behavior, stability, and performance in both established and emerging technologies. (Nanowerk Spotlight) The ...

Ion exchange separates components in a sample depending on their relative ionic strengths and interaction with the stationary phase. The stationary phase is a charged substance that selectively ...

Whether it is determining the origin of pollutants, characterizing contaminants in food, imaging individual biological cells or putting a date to historical objects, scientists use ion beams to help ...
