Odd Web Material

May 21st, 2013

Thursday’s post on lab manuals brought my attention to this nice cheat sheet from the Zakarian Group at UCSB on how to collect an NMR spectrum. I am a big fan of cheat sheets—they let you focus on the big picture when you’re getting trained on an instrument instead of focusing on recording every simple command. That said, the Zakarian NMR guide is weird. It inexplicably ends with the statement:

GO ASIAN PEEEPOH!

I guess the line is some sort of inside joke in the lab, but why on Earth would you post it to a professional Web site? It reminded a labmate of the incident where racially insensitive material was posted on Clifford Kubiak’s site, for which he later issued a public apology.

If you enjoy these sorts of jokes, keep your boss out of trouble by not posting them to your lab’s Web site.

Today’s Unit Conversion Error: Poop in Pools

May 17th, 2013

A friend on Facebook brought my attention to a very interesting article from NBC News:

People always worry about pee in the pool, but number two is the No. 1 problem, government health experts say. They found plenty of evidence that someone’s pooping in the pool. It’s not only disgusting, but it’s evidence that people are not following basic hygiene rules, says Michele Hlavsa, chief of the Centers for Disease Control and Prevention’s Healthy Swimming Program.

“It is time to stop treating the swimming pool as a toilet,” Hlavsa told NBC News. “Nowhere else except for the pool is it acceptable to poop in public or pee in public. In other places if we did this in public, we’d be arrested.”

The pool-poo expert went on to say:

“The average person has about .14 grams of feces on their rear end,” Hlavsa said. “If that rinses off into the water, the amount from one person might not be that much. But as more and more swimmers introduce it that much, it does become an issue.”

She’s actually done the math.

“Let’s imagine 1,000 kids go to a water park. They have as much as 10 grams of feces on their rear ends,” she said.  “We are now talking about 10,000 grams or 10 kg. That translates to 24 pounds of poop in the water.”

I am willing to grant Hlavsa’s obscenely high estimate of 10 grams of poo per bottom—which does lead to 10 kg of poo per 1000 bottoms—but that does not equate to 24 pounds! The correct conversion factor for poo (or any other substance at the surface of Earth) is 2.2 pounds per kg.

I am immensely relieved her hypothetical pool contains only 22 lbs. of poo.



Lab Manuals

May 16th, 2013

ChemBark's Orby the InsectI’m always interested to come across instructional documents on chemistry professors’ Web sites. These documents can be great resources, because they often contain very practical advice about safety, direction on how to maintain instruments, and guidance on experimental technique from experts in the field. Taking the time to commit this information to writing also helps prevent “institutional” loss of memory when senior members of the lab graduate without having properly trained the next generation of students.

Unfortunately, you don’t come across that many lab manuals online. Perhaps this is because some of them are distributed in hard copy only. Perhaps, some professors don’t want to explicitly write procedures and safety guidelines in fear they might be used against them in court. My guess, however, is that most people can’t find the time to sit down and write out this information—or they don’t see the value in doing so.

Jim Tour’s “Guidelines for Research” is among my favorite documents. He gets very specific about some of the advice he doles out. For instance, all nitrogen bubblers left on overnight should have a flow rate of one bubble per second or less. Tour provides guidance on how he likes notebooks to be kept, and he also provides expectations about work ethic and vacations. Finally, there is the passage on personal hygiene:

Personal Hygiene: Although not customary in all countries, Americans generally bathe at least several times per week. As a result, many Americans are offended by the infrequent bathing habits of others (whether Americans or internationals). Thus, you may be leaving a negative impression of yourself without ever knowing it. Unfortunately, bad impressions are often difficult to overcome. Likewise, be sure to use an underarm deodorant since most Americans find body odor to be most offensive. I have seen people causing themselves to be ostracized by others simply because of poor personal hygiene habits.

It might seem trifling or overbearing to provide advice on this level, but the info is correct and I wish more people heeded Tour’s advice.

While the idea of writing a manual all at once seems daunting, I think that doing it in pieces seems quite reasonable. In fact, I think you can assemble some really good tidbits of advice from material that is already posted online. These documents are almost like official memoranda to members of professors’ labs. For instance:

The famous “How to Write a Scientific Paper” article in Advanced Materials had its beginnings as a type-written memo from George Whitesides to his lab.

There’s also Ken Suslick’s cool presentation on how to give a talk.

And I like how some professors provide specific instructions on how to ask them for letters of recommendation.

Anyway, before I go writing similar stuff in the future, I wanted to know if you all had come across any great lab manuals or memos. Leave them in the comments, and I’ll compile a list below.

An Interesting Position at Columbia

May 14th, 2013

I don’t know why I find myself writing so many posts about happenings at Columbia, but I do. And the trend continues, thanks to this ad I found on page 84 of the March 18th edition of Chemical & Engineering News:

 IMG_2756

The ad begins:

THE DEPARTMENT OF CHEMISTRY seeks to appoint an Associate in Discipline beginning July 1, 2013, for our busy undergraduate laboratory programs. This is a full-time special instructional faculty position with multiyear renewals contingent on successful review…

An Associate in Discipline, you say? Great. I can think of a few chemists at Columbia who need to be disciplined (1 2)…



ACS President-Elect Tom Barton Seeks Input on Fracking

May 8th, 2013

Tom Barton won last year’s ACS national election for President (and was kind enough to answer our questionnaire about important issues facing the society). Yesterday, President-Elect Barton asked that I share this message with the readers of the blog:

In my ACS presidential year of 2014 I’m considering hosting a symposium on fracking with, of course, emphasis on the involvement of chemicals.  I would appreciate hearing from anyone suggestions for particular areas for inclusion, and potential speakers.  I seek a balanced set of presentations from experts in the various aspects, and would certainly be interested in any germane research.  I myself am not an expert in this arena, but I am trying to get smart in it.  In advance, I appreciate your assistance.

Feel free to weigh in using the comments. I will leave the first…
