Nuclear Isomerism

Electrochemichromic Systems for Display Applications

“…On the other hand, there are certain electrochemical effects (3,(11)(12)(13) occurring in liquids which also show a relatively efficient EC effect. The color change in these systems can be due to one of three different mechanisms: The first is electroplating, either of metals (12) or of nonmetallic elements (13).…”

“…The color change in these systems can be due to one of three different mechanisms: The first is electroplating, either of metals (12) or of nonmetallic elements (13). The sec-955 ond is based on a pH indicator effect, i.e., when the pH value near an electrode is changed by an electrochemical reaction, certain chemicals in an aqueous solution may either change color or fluoresce (11). A third mechanism depends upon the fact that an ion or molecule can be reduced or oxidized at an electrode, changing to a color absorbing species.…”

“…Since H + ions are reduced and combined with oxygen to form water which has an activity of 1, the boundary condition for this problem is the same as that for the HVDB-KBr system, as given by Eq. [A-2], [11], and [A-4]. Thus, the solutions given in Eq.…”

Electroluminescence and Field Effects in Phosphors

“…Alburger (79) has also discussed materials which he calls "electroflors". These are liquids which show no luminescence under u. v. excitation in the absence of a voltage but which become luminescent when a voltage is applied.…”

Some Lifetime Measurements of Isomeric States in the Rare Earth Region With Magnetic Coincidence Beta-Ray Spectrometers

“…This will be followed by a brief review of experimental methods available for measuring lifetimes of excited nuclear levels. Two general references, one by Alburger (1) and one by Bashandy (2),were used in the preparation of this section and may be referred to for a more detailed review.…”
