New evidence is presented to substantiate the electrochemical formation, at certain temperatures, of Ag2O3as a reasonably stable species under galvanostatic conditions in aqueous KOH electrolytes saturated with Ag2O and O2. The experimental data offer a better understanding of the nature of the Ag2O/AgO transition peak.

The article discusses U.S. President Richard Milhous Nixon's defense budget as of January 1972. It states that for the past three years, federal defense budgets have been 33% lower than the 42 billion dollars spent on the Vietnam war in 1968. It reports that Nixon has asked for a 6.3 billion dollar increase for defense, but even should Congress approve, only 3.5 billion dollars will actually go to defense contractors and suppliers. That amount could be reduced further if an arms limitation agreement with the Soviet Union pushes through.
