Tight junctions are intercellular adhesion complexes in epithelia and endothelia that control paracellular permeability. This paracellular diffusion barrier is semipermeable: it is size- and ...

At the heart of all lithium-ion batteries is a simple reaction: Lithium ions dissolved in an electrolyte solution ...

Dot and cross diagrams help us to model when ions are formed from atoms. Here’s an example using sodium and chlorine. They form ions which bond to form sodium chloride. 2. Work out how many electrons ...

Scientists have discovered how to keep a promising new type of lithium ion battery cathode from developing a crusty coating that degrades its performance. The solution: Use a simple manufacturing ...

Researchers at the University of Innsbruck have created a system in which individual qubits—stored in trapped calcium ions—are each entangled with separate photons. Demonstrating this method for a ...
