Materials structure can at times have as profound an impact on properties as chemical composition.
PepsiCo is testing a new type of salt whose crystals are shaped in a manner that reduces the amount of sodium humans ingest. Duke researchers developed metamaterials that derive unique electromagnetic properties from their physical structures.
Now, a California startup company called EoPlex is manipulating tiny bricks of materials to enhance performance. EoPlex CEO Arthur Chait says that voxel deposition in the company’s patented High-Volume Print Forming can produce micron-level metastructures. Chait says a Voxel is like a tiny Lego brick. Little bricks made of a given material can be “woven” through the printing process with little bricks made of another material to create metastructures of multi materials that normally don’t bond. Chait says that metastructures made this way offer the potential to increase bandwidth in small antennas.

A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
Although bio-based polymers face challenges from petroleum-based polymers, in certain markets they can displace the petro-based incumbents. Here are six new bio-based and renewable plastics for a variety of applications.
BASF has developed tools and initiatives to help engineers use more of its renewable materials in their designs, more effectively, as well as to build parts using them with more predictable performance.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
A slew of announcements about new materials and design concepts for transportation have come out of several trade shows focusing on plastics, aircraft interiors, heavy trucks, and automotive engineering. A few more announcements have come independent of any trade shows, maybe just because it's spring.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
