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 ...
Despite being one of the most familiar substances on Earth, water holds many secrets that scientists are still working to ...
Water, though familiar, still hides astonishing secrets. When squeezed into nanosized channels, it can enter a bizarre “premelting state” that is both solid and liquid at once. Using advanced NMR ...
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 ...
The influence of bromide ion on the formation of nonpurgeable organic bromine and nonpurgeable organic chlorine was not studied previously because no analytical technique existed that could separately ...
