Amorphous semiconductors
Physics Today 29 (10), 23–31 (1976);
https://doi.org/10.1063/1.3024406
Research on their electronic states, vibrations and structural changes helps us understand these glasslike materials, which show promise in switching and amplification, as memories, and for silverless photography.
Ion channels in nerve membranes
Physics Today 29 (10), 33–39 (1976);
https://doi.org/10.1063/1.3024408
The membranes of nerves, which play a key role in the conduction of impulses, are now believed to be traversed by protein channels with ion pathways opened and closed by the membrane electric field.
The laser instability
Physics Today 29 (10), 42–49 (1976);
https://doi.org/10.1063/1.3024409
Exploring the analogy of the lasing transition to such critical phenomena as ferromagnetism and the onset of convection in fluids leads to a clearer picture of the behavior of cooperative systems.
