On the first day of our visit to Walt Disney World, my then-seven-year-old son got lost in the Magic Kingdom. Luckily, he was somewhere on Tom Sawyer Island, so our search area was limited. On the second day, he wandered off in the Honey, I Shrunk the Kids attraction (also an enclosed space, thankfully). Those experiences gave me an idea for what I called Kid LoJack — a biocompatible microchip that parents could inject under a baby’s skin, and later activate to locate the child if he or she got lost or kidnapped (or stayed out past curfew). I’ve often wondered — civil liberties issues aside — whether I could have patented such a device.
This year’s Pharmaceutical Process Analysis Roundtable (PPAR) met in late September at the Lilly Technology Center in Indianapolis, IN — marking the event’s return to its roots. The first PPAR gathering, held there in the fall of 2000, was a spin-...

Laboratory notebooks and provisional patent applications can be valuable components of an engineer’s patenting strategy if they are well-prepared, appropriately managed, and diligently followed up with a nonprovisional patent application.
John F. Murphy, P.E.
Layer of protection analysis (LOPA) is a simplified process risk-assessment technique that uses order-of-magnitude estimates for initiating events, consequence severity, and likelihood of failure of independent protection layers (IPLs) to approximate the risk of a scenario. It is generally used after a process hazard analysis (PHA) team has identified a hazard scenario that requires further analysis to ensure the adequacy of the safeguards that exist or are being proposed.
The ubiquity of digital and server-stored file formats has brought about increased interest in ensuring that creative works conceived today will be preserved, digitally, forever. Chemical engineers play an important role in preserving this in DNA...

E. coli can be genetically engineered to mimic the complex natural process by which a spider makes the proteins that it uses to spin the fibers for its web. With additional processing, fibers with properties similar to those of natural spider silk...
A filter on the suction of a pump frequently plugged. Because of this, the pressure needed to be monitored, both in the field and at the control panel. To minimize installation time for a pressure transmitter, it was decided to install a tap on the...

Centrifugation is a necessary step in many pharmaceutical and chemical production processes. These guidelines will help chemical engineers better understand the process of centrifuge selection.
The December 2011 Beacon described an incident where a missing plug on a vent line resulted in a flammable material leak that caught fire, causing a fatality. That incident reminded us of the importance of caps and plugs on process vent lines and...

I love soaking up nature — whether I’m hiking over the red rocks of Sedona, strolling along Jones Beach as the waves of the Atlantic Ocean roll in, taking shelter indoors as an angry thunderstorm rages outside, stargazing miles from the nearest town … or just sitting on my porch watching the grass in my tiny New York City yard grow. Whatever the activity, I continue to be amazed at the awesomeness of the world we live in. Yet I wonder what the planet will be like for our children. Will nature still be as wonderful for them as it is for me?

If you saw my last two editorials, you probably noticed the sustainability theme — “On the Path to Sustainability” in July, and “AIChE’s Path to Sustainability” in August. Through our work as chemical engineers, we have the potential to make significant positive impacts on sustainability. There’s also much we can do as individuals.
Blogs have come a long way since their first appearance in the late 1990s, when they were little more than online diaries. Today, people are just as likely to turn to blogs (Internet shorthand for “Web log”) as to newspapers or magazines for information and news.

I was taught that the word hopefully means “in a hopeful manner” or “full of hope.” Authors who start a sentence with the word hopefully usually mean “I (we) hope” or “it is hoped” — which is an incorrect usage of the word.
