The transitions from metallic to critical behavior and from critical to insulating behavior have been induced with a magnetic field, and from insulating to critical and then to metallic behavior with increasing external pressure.

The scaling theory of localization demonstrated that the disorder-induced M-I transition was a true phase transition with a well defined critical point.

In spite of the evidence for the disorder-induced M-I transition as inferred from the transport and optical measurements, the metallic state of conjugated polymers has been a subject of controversy.

The day he is out of baseball will be the day he starts to think about what comes next. By then, it may be too late.

Polymeric materials in the form of wood, bone, skin and fibers have been used by man since prehistoric time. Although organic chemistry as a science dates back to the eighteenth century, polymer science on a molecular basis is a development of the twentieth century.

We put increasing pressure on ourselves.
