Tight junctions form a seal between cells that is so strong that not even ions can pass across it. Gap junctions are involved in cellular communication — not just in epithelial tissue ...

a combination of extracellular molecules on other cell surfaces. Gap junctions (yellow) are clusters of channels that form tunnels of aqueous connectivity between cells.

With the strong associations established in epidemiologic studies and a dearth of evidence on the actual mechanisms by which ...

1 Neurons are composed of a cell body containing the nucleus, dendrites that receive chemical, electrical, or other signals via receptors or through gap junctions (direct connections between two ...

These communities and "hotspots" emerged in advanced stages of lymph gland development, and required the existence of tiny ...

Even with some other semiconductor material with a higher band gap, peak efficiency could only go as high as 33.7%. A multi-junction solar cell developed by NREL. It glows red due to gallium ...

In a type-I heterojunction, the band gap of one semiconductor is completely contained ... Heterojunctions are the building blocks of high-efficiency solar cells, such as multi-junction cells and ...
