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).

In many serious events, there may have been more people in the area than were needed to do or monitor the job. Too many people in the area, whether the control room or the plant, can be a distraction, causing bad decisions that could lead to serious...
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.

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.

A round of applause welcomes Rachael Ray’s next guest, a cosmetic chemist and full-time beauty blogger, who immediately launches into a detailed explanation of the science behind an unfortunate truth: Yes, you can get hooked on lip balm. In the span of four minutes, Perry Romanowski also highlights the most common shampoo formulations, explains why you shouldn’t apply body lotions to your face, and debunks one of the biggest cosmetic myths:

Robust control can be applied to design controllers that can handle process uncertainty. Learn how to use identification experiments to obtain estimates of this uncertainty.
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.
Through contributions from leading experts in diverse field, this book features the latest biomass characterization techniques, biochemical and thermochemical conversion processes, the development of integrated biorefineries, and how to mitigate the environmental risks associated with using biomass for fuel.

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.

Genome-based analytical tools enable engineers to take a systems approach to bioprocessing.
The chemical engineering curriculum has changed over the years and will continue to change in the future. In the November AIChE Journal Perspective article, “Evolving Trends in Chemical Engineering Education,” Arvind Varma of Purdue Univ. and Ignacio Grossmann of Carnegie Mellon Univ. examine this evolution and illuminate the impacts of shifts in academic research and industry needs. Taking a close look at the history and likely course of chemical engineering education provides a basis for discussing whether this trajectory is heading in the right direction to meet the needs of industry and to address societal issues.

The dynamic behavior of your process can never be modeled perfectly. However, process controllers can be designed to handle this so-called uncertainty.
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.
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.
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.
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.
