Gap junctions are specialised intercellular channels that facilitate direct communication between adjacent cells by allowing the regulated exchange of ions, second messengers and small metabolites.

Epithelial tissues are in constant interaction with their environment. Maintaining their functionality requires dynamic balance (homeostasis) and that their cell numbers are tightly regulated. This is ...

Single junction type (a) and the proposed double junction type (b) solar cells are compared with the conventional TANDEM type (c) and the proposed face-to-face type (d) multi-junction connections. A ...
