Tight junctions are intercellular adhesion complexes in epithelia and endothelia that control paracellular permeability. This paracellular diffusion barrier is semipermeable: it is size- and ...
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 ...
Hybrid electric vehicles, cell phones, digital cameras, and the Mars Curiosity rover are just a few of the many devices that use rechargeable lithium-ion batteries. Now a team of researchers has a ...
