Many kinds of stimuli-responsive polymer gels that respond to a change in their surroundings, such as changes in temperature, pH and the electric field, have been developed. They have attracted much ...

The electromagnetic field emitted by a stable laser source is the form of light that comes closest to exhibiting a perfect sine wave. However, even in this case, a constant level of quantum noise is ...
