Standards for electron probe microanalysis of silicates prepared by convenient method
Standard compositions suitable for electron probe microanalysis of various silicates are prepared by coprecipitation of specified salts with colloidal silica to form a gel which is decomposed into a powdered oxide mixture and compressed into thin pellets. These pellets of predetermined standard are compared with a silicate sample to determine its composition.

Study shows effect of surface preparations on improving thermionic emission
Specimen thermionic emitters were electropolished and electroetched to study the effect of surface preparations on improving thermionic emission. The best technique found was to electropolish the annealed rhenium surface and then electroetch it. The effect of electroetching was to remove other crystal planes faster than basal planes.

Effect of preparation procedures on intensity of radioautographic labeling is studied
Effects of tissue preparation and extractive procedures on the intensity of radioautographic labeling are presented in terms of mean grain count per cell in cells labeled with tritiated precursors of proteins or nucleic acids. This information would be of interest to medical researchers and cytologists.

Pure xenon hexafluoride prepared for thermal properties studies
Preparation of a xenon hexafluoride and sodium fluoride salt yields a sample of the highest possible purity for use in thermal measurements. The desired hexafluoride can easily be freed from the common contaminants, xenon tetra-fluoride, xenon difluoride, and xenon oxide tetrafluoride, because none of these compounds reacts with sodium fluoride.

Magnesium-zinc reduction is effective in preparation of metals
Uranium, thorium, and plutonium are effectively prepared by magnesium-zinc reduction, using uranium oxides, thorium dioxide, and plutonium dioxide as starting materials. This technique is also useful in performing reduction of metals such as zirconium and titanium.
