CEP: Catalyzing Commercialization: Producing Tailor-Made Polymers at the Commercial Scale

October

Catalyzing Commercialization
Today’s modern lifestyle demands highly functional products — from water-wicking fabrics and age-defying beauty products to patient-specific medicines and high-tech electronics — many of which rely on polymers. In turn, to meet these demands, manufacturers are asking for the ability to design and produce polymers with precise control over composition and architecture. Such sophisticated control, however, is not possible with the dominant incumbent technology, free-radical polymerization. Thanks to a process developed by Carnegie Mellon Univ. spin-out ATRP Solutions, creating the perfect polymer with exactly the right composition, size, and shape just got much easier.

CEP: Material Matters - Managing Aging Plants

Material Matters
Kirk Richardson
Many industrial plants currently operating around the world have already surpassed their design life expectancies. Despite the challenges they face, such as corrosion and new regulations, these operations continue to be productive. To maintain the status quo and continue operation, plant managers need to keep a watchful eye on every aspect of the facility, from inspection and maintenance programs to the bottom line. Of course, plant safety and the environment, both of which can rise to the top of an aging plant’s list of concerns, are always on their minds.

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.

Material Matters
Heather Stine
Polymer and polymer-lined equipment has become more common in the chemical process industries (CPI) due to its cost-effective corrosion resistance in severe chemical service. Fluoropolymer-lined steel, high-density polyethylene (HDPE)-lined steel, and polyvinyl chloride (PVC) are examples of materials used for tanks, vessels, and other CPI equipment. Economic considerations demand that the life of this equipment be extended as long as is safely possible.

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.
