Precision trimmer aids in preparing biomedical specimen blocks for ultrathin sectioning
Precision trimmer, which neatly trims biomedical specimen blocks for ultrathin sectioning, eliminates the risk of human error. Four inches in diameter and 3 inches in height, it supports the block and serves as a support for a cutting tool and can be adjusted in three dimensions.

Preparation of silver-activated zinc sulfide thin films
Silver improves luminescence and reduces contamination of zinc sulfide phosphors. The silver is added after the zinc sulfide phosphors are deposited in thin films by vapor evaporation, but before calcining, by immersion in a solution of silver salt.

Preparing rock powder specimens of controlled size distribution
Apparatus produces rock powder specimens of the size distribution needed in geological sampling. By cutting grooves in the surface of the rock sample and then by milling these shallow, parallel ridges, the powder specimen is produced. Particle size distribution is controlled by changing the height and width of ridges.

Preparation of superconducting thin films of transition-metal interstitial compounds
Sputtering technique forms transition-metal interstitial compounds into superconducting thin films having transition temperatures similar to those of the bulk materials. Since the magnetic-field and current-carrying properties of the films exceed those of the bulk materials, they may have applications other than in tunneling devices.
