CEP: AIChE Journal Highlight - An Inverse Approach to Materials Discovery and Design

August
2014
Journal Highlight
The success of many emerging technologies hinges on the discovery of new materials that exhibit a combination of desired properties. Identification, synthesis, and fabrication of suitable materials for these applications remain challenging, relying on resource-intensive exploratory science. A better approach might be to begin with the target macroscopic properties in mind and then systematically narrow the list of possible material precursors and synthetic methods through an optimization technique.

CEP: AIChE Journal Highlight - Zeolites Lose a Dimension but Gain in Performance

July
2014
Journal Highlight
Zeolites are widely used in the chemical process industries as catalysts and adsorbents. While the unique pore structure of zeolites is beneficial, many long-standing challenges in catalysis, adsorption, and membrane separations, as well as in nontraditional applications in energy storage and electronic and optical materials, cannot be met with the currently available porous materials.

CEP: Catalyzing Commercialization - Zero-Emissions Magnesium Process Debuts

March
2014
Catalyzing Commercialization
A process designed to lower the cost of magnesium metal, making it competitive with aluminum, has been an industry goal for over a century. Although magnesium metal makes up millions of today’s lightweight cell phone and laptop cases, its persistently high cost (twice that of aluminum today) has impeded broad, high-volume use in other areas, including the automobile industry. This could soon change, thanks to researchers at INFINIUM, based in Natick, MA, who have developed a low-cost, energy-efficient, zero-emissions process for making this lightweight, strong metal.
