AIChE Journal Highlight - Red Blood Cells Disguise Nanoparticles for Biomedical Applications

March
2015
Journal Highlight
Nanoparticles (NPs) loaded with therapeutics provide a way to target the delivery of drugs to specific locations in the body. When injected intravenously, however, nanoparticles are often recognized by the immune system and rapidly cleared from the body. Efforts to extend their residence time in vivo have focused on modifying particle surfaces to evade the body’s natural defenses. Polyethylene glycol (PEG) is currently the gold standard for such nanoparticle stealth coating, but the recent observation of an anti-PEG immunological response has spurred the search for improvements. To address this challenge, researchers have looked to nature, which has created the ideal drug-delivery vehicle — red blood cells (RBCs).

Catalyzing Commercialization
Improvised explosive devices (IEDs) are not just a threat to military troops but to civilians as well. Thwarting these attacks will require many measures, one of which is improved screening technologies. Vaporsens, a Univ. of Utah spin-off company, is developing a sensor that could meet the need for a portable, inexpensive explosives-screening device.

CEP: Process Safety Beacon - What Is the Process Risk?

January
2015
Process Safety Beacon
The worst process incident that can happen in your plant may not be the same as the highest process risk. Risk is a combination of how likely an incident is and how bad the consequences could be. The process incident in your plant with the worst consequences may be very unlikely to occur. Other less-severe incidents may be more likely, making the risk of these events higher than the incident with the worst consequences. You should be aware of all process risks in your plant, and your role in managing all of them.

CEP: AIChE Journal Highlight - Solving Wicked Sustainability Problems Requires a New Approach

December
2014
Journal Highlight
The challenges facing the world today — including climate change, resource scarcity, food security, water access, and energy demand — are fundamentally different than those of the past. These sustainability issues can be thought of as “wicked” problems — a concept that originated in the 1970s to describe the difficult challenges facing urban planners at the time and that has now spread to other areas, including engineering. In contrast with so-called tame problems, which can be solved by traditional linear, analytical approaches, wicked problems are much more intractable and very difficult to solve.

CEP: Process Safety Beacon - Bhopal – The Worst Industrial Disaster in History

December
2014
Process Safety Beacon
Thirty years ago — just after midnight on Dec. 3, 1984 — a pesticide plant in Bhopal, India, released approximately 40 tons of highly toxic methyl isocyanate (MIC) into the atmosphere. There were thousands of fatalities, hundreds of thousands of injuries, as well as long term health, environmental, and economic impacts. This incident is widely considered to be the worst industrial disaster in history.

Process Safety Beacon
In August 2014, the U.S. Chemical Safety and Hazard Investigation Board (CSB) reported the results of an investigation into a December 2010 explosion in a titanium and zirconium scrap-metal processing facility in West Virginia. The explosion caused three fatalities and one injury. Here is a brief summary of what is believed to have happened.

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

October
2014
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: Journal Highlight - A Path Toward the Perfect Chemical Reactor

October
2014
Journal Highlight
The ability to control chemical reactions to efficiently and selectively produce the desired products has vastly improved over the past decades, with increasingly sophisticated techniques now available to dictate the outcome of these reactions. While much progress has been made, much more is needed to realize a perfect reactor, which would allow for full control of chemical transformations at the molecular level. In the October AIChE Journal Perspective article, “Practical Challenges in Energy-Based Control of Molecular Transformations in Chemical Reactors,” Andrzej Stankiewicz, Izabela Szydłowska Franssen, Daniel Irimia, and Georgios Stefanidis of Delft Univ. of Technology expand on this topic of molecular control in chemical reactors.
