Technical Entity Trends: A Critical Problem to Solve

Technical Entity Trends
Derrick Wu
We treat our phones as necessary extensions of ourselves, and it is now hard to imagine life without what has become like an additional limb. Similarly, we have grown so used to computers, cars, and items requiring batteries that many of us would...

Nano-technology: Fueling the Chemical Industry's Future

Special Section
Daniela L. Carrillo, Tim Harper, Paul Holister, Mindy Rittner, Mihail C. Roco, Cristina Roman Vas
Nanotechnology, as a whole, is still an emerging area with the need to make progress in both scientific and technological terms before enormous commercialization of products may occur. Nevertheless, commercial products are out there — more in some...

CEP: Catalyzing Commercialization - A Biodegradable Plastic Made from Waste Methane

Catalyzing Commercialization
What if we could make the Great Pacific Garbage Patch just disappear? What if plastics didn’t accumulate in our landfills? What if we could reduce greenhouse gas emissions while replacing up to 30% of the world’s plastics with a biodegradable substitute? Researchers have tried for decades to achieve these goals. One approach being taken is the development of an efficient production process for poly-hydroxyalkanoate (PHA) — a biodegradable polymer similar to the polypropylene used to make yogurt containers.

Nanotechnology: Cause for Concern?

News Feature
Kristine Chin
Nanotechnology— it's a small science with big stakes. Some of the unique properties that make nanoscale materials useful may also pose hazards to humans and the environment. Can the EPA find a way to effectively regulate these tiny high-tech...

Using Chromatography to Separate Complex Mixtures

Back To Basics
Nathalie Fraud
Purifying high-value mixtures, such as pharmaceuticals, can be an expensive undertaking. Choosing the correct chromatography methods can improve purity and reduce processing time and cost.

Predictive Modeling in Catalysis - From Dream to Reality

On The Horizon
Ana G. Maldonado
In silicocatalyst optimization is the ultimate application of computers in catalysis. This article provides an overview of the basic concepts of predictive modeling and describes how this technique can be used in catalyst and reaction design.

Producing Nitrogen via Pressure Swing Adsorption

Reactions and Separations
Svetlana Ivanova, Robert Lewis
Pressure swing adsorption (PSA) can be a cost-effective method of onsite nitrogen generation for a wide range of purity and flow requirements.

Material Matters: Disappearing Materials in Aging Plants

Material Matters
Kirk Richardson
Replacing materials and equipment as they corrode or reach the end of their service life is one of the challenges of managing an aging plant. When a material or part is no longer available because the supplier discontinued the product line, was acquired by another company, or went out of business, it can be difficult to find another source or suitable replacement.
