‘CENtral Science’
Posted by Rudy Baum on March 15, 2010 in Ripped From the Pages, The Editor's Blog
C&EN launched “C&ENtral Science,” the magazine’s permanent blog, in March 2008, in time for the spring ACS national meeting in New Orleans. A number of C&EN staff members attending the meeting posted blog entries on everything from symposia they had attended to tchotchkes being given out by exhibitors at the meeting exposition. A smattering of readers followed us on the blog.
We created “C&ENtral Science” with a bit of trepidation. There was concern about diverting staff resources from covering hard news of the chemistry enterprise toward what some viewed as ephemera. There were questions about setting priorities. People pointed out that successful blogs often had a snarky tone that we thought was inappropriate for C&EN. Others worried that the lighter, breezier tone we were hoping to achieve on “C&ENtral Science” could detract from the perception of C&EN as a serious newsmagazine.
For the past two years, “C&ENtral Science” has been something of a grabbag. Numerous staff members attending national meetings continued to post on, yes, tchotchkes, dining experiences, and people they ran into on shuttle buses, as well as symposia and governance functions. C&EN’s informal “staff photographer,” Associate Editor Linda Wang, worked with C&EN Online Visual Designer Tchad Blair to create memorable slide shows from the meetings.

C&EN has been engaged in a major project with the ACS Washington IT Department for more than three years to create a workflow that renders all C&EN content in XML—extensible markup language—to facilitate delivery of the content electronically over the Internet and via mobile devices. That Digital Workflow Project has now morphed into the C&EN Production Automation Program, a set of four projects that will revolutionize the delivery of C&EN to its readers.
One reason the workflow project has been so complex and drawn out is that C&EN is a weekly magazine with three delivery modes—print, electronic, and C&EN Online—which we produce in parallel. We do multiple types of editing simultaneously, and the content you read isn’t final until the pages of the print edition are complete. Our workflow is inherently complicated.
Another reason, however, is the complexity of the typography and design of a magazine that covers the chemistry enterprise. Of necessity, C&EN contains many “special characters”—Greek letters and mathematical symbols, for example, to express chemical names and concepts. We have also chosen to retain many elements of classical typography, with the names of journals and the Latin names of species italicized, to take another example.
Because I have been in the magazine business for more than 30 years, I am sensitive to typography. Have you noticed how some of the elements of typography I noted above have completely disappeared from newspapers and most magazines? You won’t see Science magazine or Escherichia coli in italics in the New York Times. You almost certainly will not see α-interferon, either. I call this the tyranny of XML; it is a protocol that is powerful for the electronic delivery of content, but it is wreaking havoc on print.

I don’t have the time to fully understand zeta potential, so of course I go to Wikipedia, according to which: “Zeta potential is an abbreviation for electrokinetic potential in colloidal systems. In the colloidal chemistry literature, it is usually denoted using the Greek letter zeta, hence ζ-potential. From a theoretical viewpoint, zeta potential is electric potential in the interfacial double layer (DL) at the location of the slipping plane versus a point in the bulk fluid away from the interface. In other words, zeta potential is the potential difference between the dispersion medium and the stationary layer of fluid attached to the dispersed particle.”
Okay, that makes my head ache. And thank goodness, Steven Trainoff, director of engineering at Wyatt Technology assures me that even if I don’t exactly know what zeta potential is, I could still appreciate the importance of an instrument they are introducing at Pittcon 2010, the Möbiuζ, which Wyatt claims can more precisely and easily measure the electrophoretic mobility of proteins than other methods.
Accurate measurement of protein electrophoretic mobility—which is related to the zeta potential—is especially important in formulating protein drugs. That’s because protein drugs must be charged in a formulation. The charge must be high enough to ensure that proteins are stable—individual molecules repel each other—but not so high that not enough molecules can be crammed in the formulation. It’s therefore critical to know the charge on the molecule, which can be inferred from the electrophoretic mobility.
Now, many instruments out there can measure electrophoretic mobility, Trainoff says, but they are not good with small proteins, such as the 14.4-kilodalton lysozyme, in the high concentration that they exist in a formulation. That’s because as proteins become smaller, the noise from diffusion becomes too much. Wyatt’s new optical instrument solves this problem by using an array of 30 photodiode detectors instead of the usual single detector. The massively parallel detection system means faster detection and higher sensitivity than is possible with other instruments. For example, Wyatt’s Möbiu? can determine the electrophoretic mobility of a 1-mg/mL sample of immunoglobulin G in about 30 seconds.
Watch out for the March 29 issue for C&EN’s official coverage of Pittcon 2010. Senior Correspondent Stu Borman will summarize the highlights and trends, Senior Correspondent Steve Ritter will compile the most noteworthy instruments on display, and Senior Editors Celia Henry and Mitch Jacoby will report from the technical sessions.

I had back-to-back meetings with 10 companies while at Pittcon; some of them I’ve mentioned in earlier posts. The one that left a deep impression is Anasazi, a maker of 60- and 90-MHz FT-NMR instruments that sells 90% of its products to the education market: community colleges, 4-year colleges, and even high schools.
I completed my chemistry education without ever seeing, let alone using, an NMR instrument, and I’m so excited that high school and college students can actually use, touch, and manipulate the machine instead of just learning how to read and interpret the spectra, thanks to affordable and low-maintenance products such as those from Anasazi.
Don Bouchard, president of Anasazi, tells me that Anasazi FT-NMRs are ideal for the education market because they do not use superconducting magnets that need gases and cryogenic conditions to operate. The company does have a few industry customers, he says, for applications that can be optimally executed with the 60- and 90-MHz instruments. The
difference in price, according to Don, is significant: about $100,000 for an Anasazi instrument, including a five-year warranty vs about $225,000 + $15-30,000/per year in maintenance costs for a 400-MHz spectrometer with a superconducting magnet.
Anasazi NMR spectrometers are installed at three U.S. high schools and many colleges, including at least 20 community colleges in California, Don says.
Although Anasazi’s primary customers are from academia, Don and his wife, Julie, are at Pittcon in hopes of attracting customers from industry and government labs. Those of you chemistry teachers with some Department of Education Title III money might want to talk to them.
BPA Craziness

The sad saga of bisphenol A (BPA) and food containers reveals much about what is wrong with some environmentalists today.
C&EN has covered the health concerns associated with BPA extensively for several years. We have covered the reports of the National Toxicology Program on the health effects of BPA and the Food & Drug Administration’s difficult balancing act in regulating human exposure to the chemical.
C&EN has also covered the chemistry that makes it difficult to eliminate all uses of BPA associated with food. Senior Editor Mitch Jacoby, for example, wrote in the Dec. 15, 2008, issue (page 31) that “for many food applications, for example, in the metal-packaging industry, finding a new material with just the right combination of properties remains a major challenge” because “the materials used to coat food cans must adhere strongly, provide corrosion resistance, and withstand the high temperatures required for sterilization and processing. The coating also has to be compatible chemically with the food and cannot impart a flavor or odor.” BPA has all of these characteristics; most potential alternatives do not.

C&EN’s full coverage of Pittcon 2010 will appear in the March 29 issue. In that issue, C&EN reporters Celia Arnaud, Stu Borman, Mitch Jacoby, and Steve Ritter will synthesize the four-day scientific and exhibition fest on instrumentation/analytics in highlights of product introductions, technical sessions, and industry trends. Their stories will be C&EN’s definitive take on Pittcon. What I am posting are my mere musings.
Herrema
Whitney
We just finished from the first ever C&EN luncheon at Pittcon, attended by 100 guests. Not a bad crowd, considering that Tuesday is the second day of the exhibition. Our luncheon guest speakers were Frank Witney, president and CEO of Dionex, and Greg Herrema, senior vice president and president of analytical instruments at Thermo Fisher Scientific. Both made a strong case of the complexity of analytical challenges in the 21st century, as well as the ability of the instrumentation/analytics to develop new methods and tools to meet these challenges. So far so good.
At Q&A period, though, not one person in the audience asked a question. What’s with that? Are people too busy, shy, wary to participate? Any ideas about how to encourage discussion during a luncheon?
Altogether, the luncheon was fine. As moderator, I asked a question with several follow ups that I think the speakers and the audience appreciated.
I’m still figuring out zeta potential, but I have to catch my flight back to Washington, DC now.

As I said yesterday, what Frank O’Connor of Heidolph Brinkmann is really excited about is Demo for Donations, which the company will implement at the ACS national meeting in San Francisco on March 21-25. According to O’Connor, Demo for Donations works like this: Meeting attendees sign up for a product demonstration at Heidolph’s booth, #1110, and Heidolph will contribute $10 per sign up to the Red Cross earthquake relief fund for Haiti.
Instead of mints, ballpens, or any of the usual freebie trinkets at exhibitions to get people to stop at their booth, Heidolph believes that Demo for Donations will attract more traffic because, as O’Connor’s explains, it offers attendees “a way to give something back to the community.” I warned O’Connor that the San Francisco might attract more than 12,000 people, and Heidolph could be deluged with sign ups. O’Connor’s expectations are conservative, about 1,500.
Well, ACS national meeting attendees, perhaps you can help O’Connor exceed expectations. Again the place to do something good for Haiti in San Francisco is booth #1110.
From Heidolph, I next visited Wyatt Technologies. They’re excited about a new instrument that measures something related to zeta potential and has a key application in protein drug formulation. I’ll tell more about this advance in Part 3. Right now I have to understand what zeta potential is. Can anyone help?

For Pittcon 2010, the Orange County Convention Center is in its full glory. It’s one of the most beautiful convention centers in the county, said Annette Wilson, president of Pittcon 2010, at the opening ceremonies this morning, and I agree. It looks gorgeous from the outside. It is also huge, so huge that despite hosting more than 2,000 booths, more than 1000 exhibitors, and more than 2,000 technical papers, Pittcon occupies only the West Section. Advance registration totals more than 14,000.
I’ve had interesting conversations since the first function I attended, the Waters Symposium Dinner last night. There I met James A. de Haseth, a senior partner of a company based in Georgia called Light Light Solutions. It makes instruments that help analyze fibers as they are processed for various uses, including as alternatives to glass. De Haseth tells me the company is working with Canadian groups that are interested in natural fibers such as flax as superstrong, superlight materials for industrial applications.
Another interesting conversation was with Patricia A. Bordell, Pittcon’s chair for shortcourses. She works with the College Board, the organization best known for the SAT and the Advanced Placement Program. Bordell goes around the country and the world to train teachers who teach AP and pre-AP chemistry. The push now by the College Board, she says, is to train chemistry teachers to apply inquiry-based learning in pre-college chemistry classrooms.
Science And Public Policy

Critics of this page frequently argue that C&EN’s editor-in-chief should comment only on matters concerning chemistry or the chemical industry. There is no place, they argue, in the American Chemical Society’s newsmagazine for commentary on public policies about which ACS members might disagree. The magazine, in fact, should stay out of public policy issues altogether, in the view of some of these critics.
The stories in this week’s issue of C&EN illustrate why this criticism is unrealistic in today’s world. The first seven department stories—from the cover story to both stories in the Business Department, both stories in the Government & Policy Department, the single story in the Science & Technology Department, and even the first story in the ACS News Department—all deal with issues that have a public policy component to them. Science and technology and public policy are inextricably linked in modern societies.
For example, the cover story, “Fluorochemicals Go Short” by Senior Correspondent Steve Ritter, is a comprehensive examination of the development of a policy for dealing with two particularly persistent long-chain perfluoroalkyl compounds: PFOS and PFOA. As an interim measure, chemical companies, with EPA’s blessing, are replacing PFOS and PFOA with compounds with shorter perfluoroalkyl chain groups that impart the same functional properties as the longer chain compounds. “Although the alternatives are just as persistent, they aren’t as bioaccumulative and appear to have a better toxicity profile—which is still being confirmed by testing—and are thus considered sound replacements,” Ritter writes.

The American Chemical Society Scholars Program celebrates its 15th anniversary in 2010. The program awards renewable scholarships of up to $5,000 per year to underrepresented minority students who want to enter chemistry or chemical engineering or related fields such as environmental science, toxicology, and chemical technology.
As part of the 15th anniversary celebration, C&EN is launching in this issue a series of profiles of current and former ACS Scholars. The profiles will run in the last issue of each month.
The first profile is of Steven W. Meier, who is a member of the Citizen Potawatomi Nation, an American Indian tribe with its headquarters in Shawnee, Okla. (see page 41). Meier was an ACS Scholar at Rice University. He received a bachelor’s degree in chemical engineering from Rice, went on to receive his Ph.D. in chemical engineering from Northwestern University, and is now at ExxonMobil R&D in Annandale, N.J.
Through the year, C&EN will tell 12 of these inspirational stories. There are many, many more. The ACS Scholars Program, which won the 2001 Presidential Award for Excellence in Science, Mathematics & Engineering Mentoring and the 1997 American Society of Association Executives Award of Excellence, has aided more than 1,900 students since its inception.
