Chemical distributor Brenntag was hit by DarkSide ransomware group

Via both the New York Times and Bleeping Computer, chemical distributor Brenntag was hit by the ransomware group that hit Colonial Pipeline: 

Chemical distribution company Brenntag paid a $4.4 million ransom in Bitcoin to the DarkSide ransomware gang to receive a decryptor for encrypted files and prevent the threat actors from publicly leaking stolen data.

Brenntag is a world-leading chemical distribution company headquartered in Germany but with over 17,000 employees worldwide at over 670 sites.

Best wishes to Brenntag, and to all of us. 

Buffalo NY sulfuric acid plant told to stop operations due to SO2 emissions

Via the Associated Press, this interesting news: 

BUFFALO (AP) — The owners of a chemical plant in Buffalo are disputing a shutdown order issued by the state over sulfur dioxide emissions.

The New York Department of Environmental Conservation on Saturday directed PVS Chemical Solutions to cease operations at its plant in the Seneca-Babcock neighborhood after high sulfur dioxide emissions were detected at nearby athletic fields.

“Until PVS can prove it can operate without emitting potentially harmful SO2 into this community, either by altering operations or scaling back production, it should remain shuttered,” DEC Commissioner Basil Seggos said in a statement.

In its own statement, the Detroit-based company said the shutdown “is not justified in any way" and said it has safely processed sulfuric acid at the plant for 40 years. The company added it was given no warning about the closure order during discussions with the DEC as recently as Friday.

PVS said it “will tone down operations while we work with the DEC through the courts to remedy this situation," the Buffalo News reported.

Complaints about sulfur dioxide odors led the DEC to put an air monitoring trailer near the athletic fields last year, and the agency issued notices of violation after excess levels were detected, according to the newspaper.

I honestly was surprised to find an actual manufacturer of sulfuric acid in the United States, but there you are!

Well, we made it to another weekend. Hope you're had a good week, and hope your weekend is restful. See you on Monday. 

NYT obituary of the inventor of the Post-It Note, Dr. Sheldon Silver

Via the New York Times, a delightful obituary of the chemist who invented the adhesive of Post-It Notes: 
Spencer Silver, a research chemist at 3M who inadvertently created the not-too-sticky adhesive that allows Post-it Notes to be removed from surfaces as easily as they adhere to them, died on Saturday at his home in St. Paul, Minn. He was 80.

His wife, Linda, said that he died after an episode of ventricular tachycardia, in which the heart beats faster than normal. Mr. Silver had a heart transplant 27 years ago. Dr. Silver worked in 3M’s central research laboratory developing adhesives. In 1968, he was trying to create one that was so strong it could be used in aircraft construction.

He failed in that goal. But during his experimentation, he invented something entirely different: an adhesive that stuck to surfaces, but that could be easily peeled off and was reusable. It was a solution to a problem that did not appear to exist, but Dr. Silver was certain it was a breakthrough...

...Dr. Silver did not choose engineering or astrophysics. Instead, he graduated from Arizona State University with a bachelor’s degree in chemistry in 1962. He earned a Ph.D. in organic chemistry from the University of Colorado, Boulder, four years later. While there, he met Linda Martin, an undergraduate who was working part time in the chemistry department. They married in 1965.

He soon joined 3M as a senior chemist working on pressure-sensitive adhesives. During his 30 years at the company, he rose to the rank of corporate scientist. And while he worked on other projects involving branch block copolymers and immuno-diagnostics, none were part of popular successes like Post-it Notes...

Do read the whole thing, especially the wonderful bit about the 3M corporate golf course, as well as the connection to Lisa Kudrow.  

(what will be the modern version of a corporate golf course be? frisbee golf course? ax throwing room?)

Japanese chemical plant explosion

From Powder and Bulk Solids: 

Four people were injured in an explosion Tuesday at the Sakai Chemical Industry Co. Ltd. chemical plant in Iwaki, Japan.

Officials told Kyodo News that the blast happened at about 7:45 a.m. and that three people received burns and one experienced minor injuries during the incident. An English language report noted that the facility manufactures zinc oxide and zinc powders used in the cosmetics and paints industries.

Fire and law enforcement agencies have opened an investigation into the cause of the explosion, according to Reuters.

Interesting - I wonder why there was an explosion with zinc? Insufficient inerting? Zinc dust collecting?

The craziest nuclear story you will read today

Via Science magazine, this remarkable story: 
Thirty-five years after the Chernobyl Nuclear Power Plant in Ukraine exploded in the world’s worst nuclear accident, fission reactions are smoldering again in uranium fuel masses buried deep inside a mangled reactor hall. “It’s like the embers in a barbecue pit,” says Neil Hyatt, a nuclear materials chemist at the University of Sheffield. Now, Ukrainian scientists are scrambling to determine whether the reactions will wink out on their own—or require extraordinary interventions to avert another accident.

Sensors are tracking a rising number of neutrons, a signal of fission, streaming from one inaccessible room, Anatolii Doroshenko of the Institute for Safety Problems of Nuclear Power Plants (ISPNPP) in Kyiv, Ukraine, reported last week during discussions about dismantling the reactor. “There are many uncertainties,” says ISPNPP’s Maxim Saveliev. “But we can’t rule out the possibility of [an] accident.” The neutron counts are rising slowly, Saveliev says, suggesting managers still have a few years to figure out how to stifle the threat. Any remedy he and his colleagues come up with will be of keen interest to Japan, which is coping with the aftermath of its own nuclear disaster 10 years ago at Fukushima, Hyatt notes. “It’s a similar magnitude of hazard.”

The specter of self-sustaining fission, or criticality, in the nuclear ruins has long haunted Chernobyl. When part of the Unit Four reactor’s core melted down on 26 April 1986, uranium fuel rods, their zirconium cladding, graphite control rods, and sand dumped on the core to try to extinguish the fire melted together into a lava. It flowed into the reactor hall’s basement rooms and hardened into formations called fuel-containing materials (FCMs), which are laden with about 170 tons of irradiated uranium—95% of the original fuel.

...The concrete-and-steel sarcophagus called the Shelter, erected 1 year after the accident to house Unit Four’s remains, allowed rainwater to seep in. Because water slows, or moderates, neutrons and thus enhances their odds of striking and splitting uranium nuclei, heavy rains would sometimes send neutron counts soaring. After a downpour in June 1990, a “stalker”—a scientist at Chernobyl who risks radiation exposure to venture into the damaged reactor hall—dashed in and sprayed gadolinium nitrate solution, which absorbs neutrons, on an FCM that he and his colleagues feared might go critical. Several years later, the plant installed gadolinium nitrate sprinklers in the Shelter’s roof. But the spray can’t effectively penetrate some basement rooms...

...The resurgent fission reactions are not the only challenge facing Chernobyl’s keepers. Besieged by intense radiation and high humidity, the FCMs are disintegrating—spawning even more radioactive dust that complicates plans to dismantle the Shelter. Early on, an FCM formation called the Elephant’s Foot was so hard scientists had to use a Kalashnikov rifle to shear off a chunk for analysis. “Now it more or less has the consistency of sand,” Saveliev says....

Keeping this site secure and stable has got to be a huge task - the engineering challenges must be enormous, and the difficulty of getting good information is daunting.

The race for lithium extraction in America

Via the New York Times, an interesting article on lithium mining in the United States: 
Some of those investors are backing alternatives including a plan to extract lithium from briny water beneath California’s largest lake, the Salton Sea, about 600 miles south of the Lithium Americas site.

At the Salton Sea, investors plan to use specially coated beads to extract lithium salt from the hot liquid pumped up from an aquifer more than 4,000 feet below the surface. The self-contained systems will be connected to geothermal power plants generating emission-free electricity. And in the process, they hope to generate the revenue needed to restore the lake, which has been fouled by toxic runoff from area farms for decades.

Looks like they're using ion exchange beads for the extraction - makes sense.
