More than 75% of the world's food testing continues to rely on 120-yr-old cell-culture methods, which take days to produce results. New technology developed by scientists at Rheonix Inc., based in Ithaca, NY, is enabling a portable unit that greatly simplifies the testing through automation, providing results in hours instead of days and reducing costs. Thermo Fisher Scientific Inc. has incorporated the Rheonix technology into a new generation of PCRbased rapid analysis for the food- and beverage-testing markets.

From implant design to scaffold development and prosthetic construction, 3D printing offers unique solutions for complex problems in the biomedical sciences.
The familiar ring-shaped stain left behind after spilled coffee has dried represents a complex engineering problem involving principles of heat and mass transport, fluid mechanics, and surface phenomena (among others) whose solution has value well beyond spilled coffee, including the analysis of DNA microarrays, inkjet printing, and coating. In the May AIChE Journal review article, “Transport and Deposition Patterns in Drying Sessile Droplets,” Ronald Larson of the Univ. of Michigan examines this engineering problem — understanding the processes by which a liquid drop (containing nonvolatile solute or colloidal particles) on a surface evaporates and leaves behind the particles that form a stain.

Although corrosion resistance is of paramount importance, many factors must be considered when selecting materials of construction. Follow this four-step process to identify the appropriate material for your application.
We may think of process safety incidents as fires, explosions, and immediate injuries from exposure to toxic, corrosive, or otherwise hazardous materials. However, major spills of hazardous materials, especially into rivers or other bodies of water, are also process safety incidents. They have the potential to impact large numbers of people, including people far away from your plant.

Whether we are talking about occupational safety or process safety, normalizing a deviation can result in unsafe practices, conditions, and operations. Getting comfortable with and accepting these deviations can cause a shift in our perception of what is safe. Why does this matter? Moving the target for safe operating limits and tolerating the higher risk s associated with doing so can ultimately lead to a catastrophic incident.
