Researchers at the University of Akron have developed a high-resolution characterization system that incorporates six gel permeation chromatography columns, two light scattering detectors, a refractive index sensor, and a viscometer. The new system facilitates the study of separated macromolecules and is expected to play a role in the development of safer biopolymers for breast implants.

Capable of stopping 50-caliber, armor-piercing rounds, ALON and Spinel are hard and durable transparent polycrystalline materials manufactured using powder based processes. This article describes their unique combination of mechanical, optical, and chemical properties, and reports on recent advances in manufacturing to enable their use for critical defense, industrial, and consumer applications.

In 1845, Michael Faraday discovered that light passing through a transparent medium can be altered with an externally applied magnetic field. It is not surprising, given the science and engineering involved, that the ideal medium for observing the Faraday effect and the process by which it is made have only recently been developed. This article explains how magneto-optical sensors make use of advanced materials and processes to harness the Faraday effect, making it possible to see magnetic fields and domains with detailed resolution and instantly obtain flux density measurements over the surface of magnetic materials and magnetized parts.
