Have a good weekend

Busy week and I got the booster! Here's hoping you had a good week, and that you're going to have a good weekend as well. We'll see you on Monday. 

A bad day on a ship

Via the Seattle Times, this chemical nautical disaster in waters near Victoria, B.C. this past weekend: 

As a Canadian Coast Guard surveillance Dash 8-100 aircraft circled overhead Saturday afternoon, smoke billowed from the ship and radio communications indicated a fire spreading out of the crew’s control. A CCG officer told the ship’s radio operator, citing the view from the surveillance aircraft overhead, that “flame is appearing on the inside rows (of containers). The crew is focusing on the outside containers. The flame is headed toward the interior. Over.” 

The radio operator replied that about six containers were now on fire and that the crew was “trying to extinguish them with maximum water.”

However, shortly afterward, the Coast Guard informed the radio operator that the firefighting vessels sent to help the smoking ship “had been advised not to deploy any water” to fight the fire on board due to the nature of the hazardous material.

Canadian Coast Guard spokesperson Michelle Imbeau identified that as potassium amyl xanthate, a pale-yellow powder widely used in the mining industry. The ship’s manifest indicates that the containers held 57 tons of it.

According to safety information about this chemical, exposure to heat and moisture may cause decomposition “to release flammable, explosive and poisonous” carbon disulfide vapors.

Imbeau said that of the hundreds of containers piled on the ship’s deck, only four contained this combustible material, two of which fell in the ocean while two were damaged but remained on deck and started the fire. 

This is basically any industrial chemical shipper/purchaser's nightmare. Most of the time, it's "I worry that the package will break open on the truck" and not "oh dear, the container is burning on the ship", but quantity has a quality of its own, I guess. I didn't know this material was used for floatation in mining - guessing the rates to transport this stuff and insure the shipments just went up...

Urine + oxone + aluminum =! corrosion

Tucked into a New York Times article about SpaceX's toilets, this gem (emphasis mine):

Another Crew Dragon capsule that docked to the space station in April with four astronauts aboard has the same plumbing system as the Inspiration4 capsule. SpaceX engineers feared the same “contamination” might have occurred on that spacecraft.

The engineers’ suspicions were correct.

NASA astronauts living on the station snaked a borescope device — a cable with a tiny camera at the end — underneath the capsule’s floor and discovered traces of urine in places it shouldn’t be, Mr. Gerstenmaier said. “Yes, there was some indication of some contamination under the floor,” he said.

That raised new concerns. In space, urine is mixed with a potentially corrosive compound, oxone, to eliminate ammonia. Could the oxone-laced urine, sitting in the capsule for months, have corroded any crucial hardware?

To answer this question, Mr. Gersteinmaier said, SpaceX engineers on Earth gathered aluminum parts similar to those on the spacecraft and created a sampling of urine mixed with oxone. They soaked the parts and placed them inside a chamber that mimicked the humidity conditions aboard the space station for “an extended period of time,” Mr. Gerstenmaier said.

The wayward waste inside the Inspiration4 capsule was more voluminous than the contamination found on the capsule attached to the space station, he said, because the passengers used the capsule for three days while astronauts launching to the space station are typically in orbit for about 24 hours. The results of the ground tests appear positive so far, he said: “Luckily, or, on purpose, we chose an aluminum alloy that is very insensitive to corrosion.”

That capsule is scheduled to undock from the station in November and return home with the four astronauts it delivered in April. The ground tests with the oxone and urine are continuing.

“We got a couple more samples we’ll pull out of the chamber,” Mr. Gerstenmaier said. He did not say who provided the samples.

Pretty confident urine and oxone won't react much at all (especially enough to corrode aluminum), but it seems reasonable to run some direct studies...

Finally: historical data about US PhD chemists from the Survey of Doctorate Recipients

Via a tweet from Derek Lowe, this very interesting paper by Dr. Stephanie Cheng (a PhD economist), summarizing and extrapolating data from both the Survey of Doctorate Recipients and the Survey of Earned Doctorates. The Survey of Doctorate Recipients is the NSF's routine survey tool to look into the lifetime of doctoral graduates. 

Her paper discusses three results: 

It's taking longer to get out of grad school: "Over the past fifty years, mean time spent in graduate school has steadily increased by 2.2 years, from 5.8 years (s.d. = 2.1) among 1960-1980 STEM Ph.Ds. to 8.0 years (s.d. = 4.1) among 2000-2013 cohorts... Figure 5 demonstrates that fewer individuals are completing Ph.Ds. in fewer than four years and more individuals are completing Ph.Ds. in more than eight years over time."

Fewer people are getting tenure-track positions: "As doctoral training has lengthened and more STEM Ph.Ds. have pursued postdoctoral training, the probability of obtaining an academic tenure-track position has nearly halved over the past fifty years. Only 25.2% of 2000-2013 STEM Ph.D. graduating cohorts are ever observed in a tenure-track position, compared to 42.8% of 1960-1980 cohorts." 

Postdocs cost PhDs lifetime earnings: "To quantify the impact of postdoctoral experience on salary at each career stage, Figure 19 gives salary regression coefficients on years of postdoctoral experience for each of the first thirty years post-Ph.D. graduation, as calculated in Equation 1. The first few years show a large negative relationship due to the salary gap between postdoctoral appointments and permanent positions. This gap closes as postdoctoral researchers move into permanent positions, but the additional training does not improve their salaries enough to overcome this early loss. As given in Equation 2, the average of these yearly coefficients can be interpreted as the postdoctoral deduction in mean lifetime earnings. Rather than provide an education premium, each additional year of postdoctoral experience reduces average lifetime earnings by $3,730."

All three of these results are not new to this discussion, almost to the point that you have to ask yourself "is this news?" And my response is a confident "yes." First, it's documented quite clearly by her analysis of SDR cohorts, and it appears that not many people have decided to do this. Second, she chose chemistry specifically as one of the PhD fields to be analyzed, and so Appendix B has some really nice data to summarize her findings. Of these, I'll choose a few of note: 

• Between the 1960s and 2013, the mean years in graduate school for chemists had moved from slightly less than than 5 to slightly less than 7. 
• The number of PhD chemists who took 4 years or less dropped from 40% in the 1960s to less than 10%. Meanwhile, the number who took 6 years rose from 10% to 30%. 
• The percentage of PhD chemists since the 1980s who did a postdoc within 2 years of graduating has never been lower than 40%. 
• The percentage of chemistry postdocs who did a 1-2 year postdoc fell around the time of the Great Recession from 30% to 20%, while those who did a 3-4 year postdoc rose from 10% to 30%. 
• The percentage of PhD chemist cohorts that had a tenure-track position at anytime went from 36% in the 1960s to 10% in 2013. 
• Since 1972, the modal outcome for a PhD in chemistry 10 years after graduate was a position in industry, from a high of ~60% to a low of ~42%. 

I will end on a tiny bit of a triumphalist note. I have been banging on for a number of years about how we have a paucity of data about both the past and present of the chemistry jobs market. Dr. Cheng has done us a huge favor by providing some of it. Instead of arguments about what is and is not "traditional", Figure B.9 provides us data and tells us what was traditional from 1970 until 2010, and what I strongly suspect is still traditional today: most PhD chemists end up in industry (~40%), some have a tenure-track academic position (~20%), some work in other academic functions not on the tenure-track (~19%) and some work in non-profit or governmental settings (~19%). 

I think this paper confirms my biases is likely to be right, and the only way to figure it out is to find data to either back it up, or contradict it. Dr. Cheng has gotten us started, and we'll have to do the rest ourselves. Let's get to it. 

Have a good weekend!

Hope you had a good week. It's a quiet, relaxing weekend for me, hope it will be for you as well. See you on Monday! 

 

A more potent meth?

An unusually chemistry-heavy article in The Atlantic about methamphetamine: 

Among the drawbacks of the P2P method is that it produces two kinds of methamphetamine. One is known as d-methamphetamine, which is the stuff that makes you high. The other is l-methamphetamine, which makes the heart race but does little to the brain; it is waste product. Most cooks would likely want to get rid of the l-meth if they knew what it was. But separating the two is tricky, beyond the skills of most clandestine chemists. And without doing so, the resulting drug is inferior to ephedrine-based meth. It makes your heart hammer without offering as potent a high.

Bozenko’s sample contained mostly d-methamphetamine. Someone had removed most of the l-meth. “I’ve taken down labs in several continents,” Bozenko told me years later. No one in the criminal world, as far as he and his colleagues knew, had ever figured out how to separate d-meth from l-meth before.

Would be interesting to know how exactly clandestine chemists are performing this resolution, but it looks like it's via the tartrate salt, which is pretty reasonable. This conclusion about this newer meth was interesting and a bit skepticism-inducing: 

Why is P2P meth producing such pronounced symptoms of mental illness in so many people? No one I spoke with knew for sure. One theory is that much of the meth contains residue of toxic chemicals used in its production, or other contaminants. Even traces of certain chemicals, in a relatively pure drug, might be devastating. The sheer number of users is up, too, and the abundance and low price of P2P meth may enable more continual use among them. That, combined with the drug’s potency today, might accelerate the mental deterioration that ephedrine-based meth can also produce, though usually over a period of months or years, not weeks. Meth and opioids (or other drugs) might also interact in particularly toxic ways. I don’t know of any study comparing the behavior of users—or rats for that matter—on meth made with ephedrine versus meth made with P2P. This now seems a crucial national question.

I'm pretty skeptical that there's a major chemical difference between ephedrine-based meth and P2P-based meth, but maybe I'm wrong. It seems to be that "more meth, cheaper" is probably the horses-not-zebras answer, even as there are other, tempting explanations (contaminants, etc).

Supply chain issues hitting very basic chemicals too

Via the Associated Press: 

In an economy upended by the coronavirus, shortages and price spikes have hit everything from lumber to computer chips. Not even toilet paper escaped.

Now, they’re cutting into one of the humblest yet most vital links in the global manufacturing supply chain: The plastic pellets that go into a vast universe of products ranging from cereal bags to medical devices, automotive interiors to bicycle helmets.

Like other manufacturers, petrochemical companies have been shaken by the pandemic and by how consumers and businesses responded to it. Yet petrochemicals, which are made from oil, have also run into problems all their own, one after another: A freak winter freeze in Texas. A lightning strike in Louisiana. Hurricanes along the Gulf Coast.

All have conspired to disrupt production and raise prices.

“There isn’t one thing wrong,” said Jeremy Pafford, head of North America, market development, at Independent Commodity Intelligence Services (ICIS), which analyzes energy and chemical markets. “It’s kind of whack-a-mole — something goes wrong, it gets sorted out, then something else happens. And it’s been that way since the pandemic began.”

The price of polyvinyl chloride or PVC, used for pipes, medical devices, credit cards, vinyl records and more, has rocketed 70%. The price of epoxy resins, used for coatings, adhesives and paints, has soared 170%. Ethylene — arguably the world’s most important chemical, used in everything from food packaging to antifreeze to polyester — has surged 43%, according to ICIS figures.

It's hard to know when all the various pandemic-related supply chain issues will be over. 

The negative effects are obvious, i.e. if you can't get product, you can't sell it and your revenue projections go down, so you dial back hiring. 

It seems that there hasn't been a major impact on hiring yet, especially for the companies that do the bulk of hiring out of graduate school. That said, it bears watching, and I think it poses the largest obvious threat to the 2022 chemical employment market. Developing...

Disappearing tattoo ink?

This is a cool science entrepreneurship story (via The New York Times): 

...Ephemeral’s fading ink was invented by two chemical engineers who specialize in protein, Brennal Pierre, 41, and Vandan Shah, 33. They met at New York University, where Mr. Pierre was an adjunct professor, and Mr. Shah was a Ph.D. candidate.

Their work began in 2014 when one of Mr. Pierre’s students, who was also Mr. Shah’s research assistant, was going through a very painful and expensive laser removal process for a tattoo, and he wanted to know if it would be possible to remove it with an enzyme.

Once the question was asked, Mr. Pierre and Mr. Shah were hooked. “It was so intriguing to us,” Mr. Pierre said. They spent the next seven years developing an ink that would be broken down by the body’s natural mechanism.

...When you get a tattoo made of permanent ink, most of the ink remains where it is deposited. By contrast, Ephemeral’s ink is made of a material that the body naturally breaks down over time. The ink works in a similar way to biodegradable medical devices like stents used in implants or sutures used in stitches. These products, like the ink, are broken down naturally by available oxygen and water in the body.

Looks like to me that the inks are pretty typical inks, but the encapsulation is where the secret sauce is? 

I used to be pretty skeptical of science entrepreneurship stories, but the last ~5 years have changed my opinion broadly as to its potential applicability. I still think the problems are pretty tough to surmount (i.e. I think you (the scientist) basically needs a full-time spouse to provide health insurance, etc). Makes you wonder if the inevitable climb in interest rates will clamp down on rates of entrepreneurship...

This has been a relatively quiet week, but it's had its moments. Hope that you have a good weekend, and we'll see you on Monday.

Lawsuit filed against LyondellBasell

Via Houston Public Media: 

The father of a worker who died during a chemical leak at LyondellBasell’s La Porte facility in July filed a $1 million lawsuit against the company on Thursday.

According to the lawsuit, LyondellBasell became aware of a leak inside of the Acetyls Unit at the 1515 Miller Cut Off Road facility on July 27, and decided to delay permanent repairs — opting to instead to temporarily fix the leak.

Later that day, 32-year-old Shawn Kuhleman was working near the Acetyls Unit when more than 100,000 pounds of a mixture of harmful chemicals — including acetic acid, methyl iodide, and hydrogen iodide — was released into the complex, the lawsuit reads. The lawsuit says Kuhleman was fully exposed to “the harmful toxic chemicals which burned his body internally and externally,” resulting in his death.

36-year-old Dustin Day was also pronounced dead at the scene, and 30 workers were hospitalized.

That sounds awful. Condolences for the families of the deceased, and here's hoping the facts of what happened will be described in full soon.

Quora microwave expert Robert Schiffman dies

Via the New York Times, an obituary of a microwave food chemist: 

After earning a bachelor’s in pharmacy at Columbia University in 1955 and a master’s in analytical science and physical chemistry at Purdue University four years later, Mr. Schiffmann answered an advertisement for “a physical chemist with a sense of humor” at DCA Food Industries, a bakery equipment maker, and got the job.

It was there, in 1961, while studying the heat transfer characteristics of deep-fat frying, that he saw a co-worker place a sandwich on a paper plate inside a chrome-plated machine.

“When the guy took the sandwich out, it was warm, but the plate was cool and so was the air in the oven,” he told People. “I couldn’t get over it.”

He quickly microwaved his own sandwich, and, over the next 15 minutes, started experimenting. He microwaved doughnut dough, and then a beaker of fat into which he added raw dough, all of which eventually led to his building large microwave doughnut fryers.

The microwave - is there anything it can't do?  

BLS: quits up dramatically

Via the New York Times: 

As the economy struggles to get back on track amid the pandemic, businesses are struggling to find employees — and workers are discovering that they have leverage.

Nearly 4.3 million workers voluntarily quit their jobs in August, the Labor Department said Tuesday. That was up from four million in July and is by far the most in the two decades the government has been keeping track.

The explosion of quitting is the latest evidence that the balance of power in the labor market has swung toward workers, at least temporarily. Average hourly earnings have surged in recent months, particularly for the lowest-paid workers, and yet many businesses report they are still having difficulty finding workers.

Anyone out there quitting their jobs in the chemical or pharma industry? What are things like right now?

Cool gunpowder story

Well, this is a lot cooler than baking sourdough: 

In the early days of the pandemic, Dawn E. Riegner, a chemist at an elite college, found that she had time on her hands because of the empty classrooms. So she filled her downtime with an explosive diversion.

Dr. Riegner talked three of her colleagues — and her daughter — into studying how well different kinds of gunpowder recipes from the Middle Ages performed in firing projectiles out of a replica cannon. Her ambitious plan was relatively easy to carry out because she’s a tenured professor of chemistry at the U.S. Military Academy at West Point, N.Y., which gave her access not only to top scholars and laboratories but world-class firing ranges.

“It’s a silver lining of the pandemic,” Dr. Riegner, whose usual research centers on better detection of explosives and chemical warfare agents, said in an interview of the gunpowder study. “It’s been one of the greatest things.”

Makes you wonder what the vinegar was used for... 

NYT: new college graduates getting hired

Via the New York Times, looks like it's a good year to be a young college graduate: 

“The appetite for college labor is strong right now, whether it’s student positions, or part time, all the way through entry-level jobs,” said Jennifer Neef, director of the Career Center at the University of Illinois Urbana-Champaign.

That appetite at this stage of the pandemic — when overall U.S. employment remains more than five million jobs below the level in early 2020 — underscores the longstanding economic premium for those with a college education over holders of just a high school diploma.

The unemployment rate for all workers with a college degree stood at 2.5 percent in September, compared with 5.8 percent for high school graduates with no college. Among workers 22 to 27, the jobless rate in June was 6.2 percent for those with at least a bachelor’s degree and 9.6 percent for those without one, according to a study by the Federal Reserve Bank of New York.

“We’ve seen a bifurcation in the labor market recovery,” said Gregory Daco, chief U.S. economist at Oxford Economics. “College graduates were less affected by job losses and have seen a faster rebound while people with high school diplomas or less witnessed a much more serious decline in employment opportunities during the Covid crisis.”

 Good news for this year's grads. Will be interesting to see how long the good times keep rolling.

Professors List and MacMillan win Chemistry Nobel for organocatalysis

From the New York Times: 

The Nobel Prize in Chemistry was awarded on Wednesday to Benjamin List and David W.C. MacMillan for their development of a new tool to build molecules, work that has spurred advances in pharmaceutical research and lessened the impact of chemistry on the environment.

Their work, while unseen by consumers, is an essential part in many leading industries and is crucial for research.

From Chemical and Engineering News' Leigh Krietsch Boerner: 

The 2021 Nobel Prize in Chemistry has gone to Benjamin List of the Max Planck Institute for Kohlenforschung, and David W. C. MacMillan of Princeton University for the discovery of asymmetric organocatalysis. Asymmetric organocatalysis uses small organic molecules as catalysts instead of traditional catalysts such as enzymes or metals. These molecules are able to catalyze reactions to selectively form one enantiomer of a particular compound—meaning one version of two mirror-image molecules.

Best wishes to Professors List and MacMillan.  

Longread of the day: using data science to mine cobalt

Via Bloomberg: 

Late in August, at a precisely specified point in the low Arctic, a geologist named Dave Freedman stood in a raw wind and a limitless expanse of tundra and began to thwack with a sledgehammer at a rock outcrop jutting up from the soil.

Freedman, 29, works for a company called KoBold Metals, and the process that had brought him to this pair of GPS coordinates in Quebec’s far north was complex. But the rock had had its own journey. Before it was rock, it had been magma in the Earth’s mantle, part of a molten tongue tens of meters wide that had welled up as two tectonic plates spread apart 1.85 billion years ago.

Lots of interesting chemistry within.

C&EN: Chinese power outages affect chemical production

In this week's Chemical and Engineering News, this news (by Hepeng Jia): 

China’s chemical sector is enjoying a profit surge, but continued prosperity is threatened by spreading power outages and the nation’s attempt to control carbon emissions.

China’s National Bureau of Statistics says profits in the chemical industry rose by 145% in the first 8 months of the year, nearly tripling the average industrial profit increase.

But the streak could be coming to an end. In recent days, at least a dozen stock market–listed Chinese chemical manufacturers—ranging from fertilizer producers to polyester fiber firms—have announced production curtailments due to lack of electricity.

In addition, on Sept. 23, the US firm Celanese declared force majeure for several polymers after it was forced to shut down acetic anhydride and vinyl acetate facilities in Nanjing, in Jiangsu Province, to comply with government orders. Nationwide, thousands of chemical factories could be impacted by power cuts, says China Petrochemical News.

The publication quotes several chemical firms’ executives in Jiangsu Province and the regions of Inner Mongolia and Ningxia as complaining that the unstable electricity supply is hampering maintenance, feedstock loading, and production safety.

 I imagine this will have the effect of driving Chinese prices up, which will have further inflationary effects on the world economy. I think I expected inflation to pop up eventually, but how it's affected the global economy and why have been beyond me. 

Cool art techniques

Via the New York Times, this neat bit of spectroscopy: 

The year was 1791, and while Marie Antoinette may not have had the favor of the people of France, she did have a pen pal. Her confidant, Axel von Fersen, was a Swedish count, and one of the French queen’s close friends.

Between the summers of 1791 and 1792, though the queen was kept under close surveillance after a botched escape attempt, she still managed to sneak letters to the Count of Fersen. He copied the letters, which are now held in the French national archives. But between the time the letters were written and the time they arrived at the archives, some mysterious actor censored the letters, scrawling out words and lines with tightly looped circles of ink.

The content of the censored lines — and the identity of the fastidious scribbler — eluded historians for nearly 150 years. In a paper published on Friday in the journal Science Advances, scientists have now revealed the redacted content of eight of the censored letters between Marie Antoinette and the Count of Fersen. The researchers used a technique called X-ray fluorescence spectroscopy, which can detect the chemical signatures of different inks without damaging documents.

...The method that prevailed was X-ray fluorescence spectroscopy, or XRF, which differentiated the chemical signature of the ink used by the original author and the ink used by the censor. The initial XRF scans revealed that both texts had been etched with metal-gall ink, a common ink made with iron sulfate. “But the iron sulfate is not pure most of the time,” Dr. Michelin said. “It contains other metallic elements, like copper and zinc. With that slight difference, we can differentiate the inks.”

In some letters, copper was present only in the original ink, so isolating the element on its own would remove the censor. “So just with the map of the copper, I can read the text,” Dr. Michelin said...

 It seems that art science always has the best stories. 

Have a good weekend

Well, here we are at the weekend. Hope that you had a good week, and that you have a good weekend. See you on Monday! 

LIDAR for bear mass

Me, after dinner on Thursday

Always cool to see what instruments of science can be used for (via High Country News): 

“I got a laser return from the butt of Otis, one of the more famous brown bears up there,” Cusick said. “I thought, ‘Wow, this just might work.’” 

Lidar, which stands for “light detection and ranging,” emits beams of light to measure three-dimensional objects or areas. When light waves hit an object, they bounce off and return to the sensor. Computers then use the speed of light to calculate the distance between the sensor and all the points. That figure is then processed using software that can model a three-dimensional object. Scanners have become standard technology that is deployed from the ground, the sky and satellites to measure vegetation growth. Now, they’re being used to measure bears’ length, height and girth.

Insurance companies are probably going to start using LIDAR to measure their policy holders...
