‘Dirty Bomb’ Terrorism

Meinhold TalksOn ABC, CBS Pushing the concept of “sur-

vival of the fittest” to theextreme, Mow Lin of the EnergySciences & Technology (EST)Department, and EST retiree Eu-gene Premuzic have developedstrains of bacteria able to live inharsh environments whilechowing down on carbon-richmaterials such as coal. Thebacteria’s digestive action re-moves potentially harmful pol-lutants and could be used toyield more-efficient, cleaner-burning coal.

“These bacteria can convertordinary coal to an environmen-tally attractive resource,” saidLin. He and Premuzic were re-cently awarded U.S. Patent No.6,294,351 for this work.

Coal is one of Earth’s mostabundant fossil fuels. But burn-ing it presents environmentalproblems, including the releaseof atmosphere-polluting sulfurand nitrogen oxides, and left-over ash containing toxic met-als. While other scientists haveattempted to use bacteria to re-move impurities, they foundthat most microbes are unableto survive the harsh conditionspresent when processing coal.

Lin and Premuzic, who havepreviously developed bacterialstrains that digest oil, decided tostart with bacteria naturallyadapted to extreme conditionsand see if they could change themicrobes’ diet. The bacteria were

“Most materials get com- pacted or fall apart under

pressure,” says Thomas Vogt,Physics Department. But he anda team of international collabo-rators recently discovered somematerials with a property theycall pressure-induced expansion:they expand when squeezed.

“This is not supposed to hap-pen,” said Vogt. “Normally,when you squeeze something,it’s supposed to get smaller. Thisstuff gets bigger.”

These unusual materials mayhave applications as “molecularsponges” for soaking up chemi-cal pollutants or even radioac-tive waste.

The idea, according Vogt, isthat you squeeze a fluid into tiny

New Property Discovered — Zeolites That Expand Under Pressurepores in the material, thereby in-creasing its volume. This extravolume can also allow slightlylarger molecules or atoms, suchas pollutants, to enter the ex-panded pores. “When the pres-sure is released and the materialcontracts, the pollutant wouldbe trapped inside,” he said.

Vogt and his collaborators —Yongjae Lee, a postdoc in Phys-ics; John Parise, a Stony BrookUniversity chemist; JosephHriljac, formerly of BNL andnow a chemist at the Universityof Birmingham, England; andGilberto Artioli from the Univer-sity of Milan in Italy — describeone such material in the Decem-ber 19, 2001 issue of the Journalof the American Chemical Society.

The materials are all zeolites— solids containing aluminum,silicon, and oxygen with a three-dimensional structure contain-ing regularly spaced pores. Thesenanopores, which are on the or-der of billionths of a meter, makezeolites very useful for taking upsmall molecules, ions, or gases— just like a sponge soaking upwater.

In fact, the pores are nor-mally filled with positivelycharged ions, such as calciumand sodium, as well as watermolecules. So zeolites are saidto be hydrated. Many are cur-rently used as water softenersand in detergents.

Previous studies elsewheresuggested that some zeolites

have unusual properties underpressure. The collaborative teamwas investigating these proper-ties when they discovered thatone zeolite could suck up twicethe normal amount of water —a superhydrated zeolite.

Using a technique calledpowder diffraction at BNL’s Na-tional Synchrotron Light Source(NSLS), the team has decipheredthe zeolite’s molecular structure,which for the first time explainsthis unusual property and showswhere the extra water goes.

Vogt and his colleagues havesuggested several ways to takeadvantage of pressure-inducedexpansion, found in only certainzeolites. One would be to set upa “trap door” mechanism forlocking up chemical or radioac-tive pollutants.

“When you increase the pres-sure and the material gets big-ger, the pores get bigger, too,”Hriljac said. “So we can try to getbigger ions or molecules inthere, such as hydrocarbons,mercury, lead, or even radioac-tive strontium. Then, when yourelease the pressure, the porewould get smaller and trap thepollutants inside.”

The scientists plan to con-tinue their studies on the ex-panding zeolites to see if this ap-proach will work.

contaminants. The resultingcleaner coal can be burned orconverted to liquid or gaseousfuel much more efficiently thanuntreated coal, while producingfewer environmentally undesir-able by-products.

“The best results can beachieved by using a combina-tion of the newly adapted organ-

isms, wherein each is very effi-cient at degrading one or moreof the desired sites within thecomplex structure of coal,” saidLin. “This mixed-culture ap-proach permits us to tailor themicrobial package to transformdifferent types of coal and othercarbon-containing materials.”

isolated from geothermal loca-tions in the South Pacific andNorth America.

Using a technique called“challenge biosynthesis nutri-tional stressing,” Lin and Premu-zic first cultured the bacteria ina medium containing smallamounts of crude oil, supple-mented with other nutrients.

The bacteria that survived inthe presence of oil were thentransferred to a new culture me-dium with a higher concentra-tion of oil and lower levels ofother nutrients. This process wasrepeated in steps, gradually in-creasing the oil content andeliminating other nutrients, un-til the surviving bacteria coulduse oil as their only food source.

The scientists then used thesame process to wean the oil-eat-ing bacteria off oil while givingthem increasing levels of coal.

“Essentially, we force the bac-teria to adapt to the new foodsource,” said Lin.

By gradually altering environ-mental variables such as tem-perature and acidity in a similarfashion, the BNL team has de-veloped several strains of coal-adapted bacteria that can surviveunder a variety of extreme con-ditions. When combined with aslurry of coal, these new mi-crobes break down the coal’scomplex molecules to form sim-pler ones, and concurrently re-move sulfur and heavy-metal

BNL’s Charles Meinhold,a guest scientist in the

Nonproliferation & NationalSecurity Department andpresident of the NationalCouncil on Radiation Pro-tection & Measurements(NCRP), was a featuredexpert on an ABC News“Nightline” segment onnuclear terrorism, December5, 2001. He is scheduled toappear again this Sunday,February 3, between 9 and11 a.m. on CBS’s SundayMorning News.

Meinhold, who retiredfrom the Lab in 2000, is inhigh demand because of hisrole as NCRP president inpreparing the Council’s re-ports, in particular the reporton “Management of Terror-ist Events Involving Radio-active Material.”

This report, funded byDOE, analyzes aspects of ter-rorist events involving radio-activity, including psycho-logical effects and their im-plications for and impacton public communication,training, and response. Itwas published October 24,2001, after two-and-a-halfyears of preparation.

U.S. intelligence officialswere concerned about nuc-lear terrorism well before theterrorist attacks of Septem-ber 11. The Nightline pro-gram featuring Meinholdand the NCRP report was fo-cused on the threat of “dirtybombs” — ready-to-explodecanisters of radioactive ma-terial mixed with conven-tional explosives. Groupslike Al Qaeda have expressedinterest in these weapons,and Osama bin Laden haspublicly declared that his or-ganization has such materi-als and that it is “a religiousduty” to use them.

Meinhold and the otherexperts interviewed byNightline agreed that thedirty bomb, also known as“the poor man’s nuke,” istoo small to have muchwidespread radiological ef-fect. Its real impact is ex-pected to come from the fearit creates and the need toevacuate and clean up largerareas than would be affectedby a conventional bomb.

“Is the average hospital orfire department in the aver-age city well prepared forthese incidents?” Nightline’sTed Koppel asked Meinhold.

Physicist Hans Willutzki ofthe Physics Department, whohad joined BNL on April 2, 1986,died on December 12, 2001. Hewas 58.

Willutzki earned his Ph.D. atHamburg University, Germany,in 1973. After his arrival at BNL,he spent most of his effort onE852 experiment at the Al-ternating Gradient Syn-chrotron. The E852collaboration waslooking for evidenceof new, rare particlescalled exotic me-sons, which wouldcontain an unusu-al combination ofgluons and quarks.These mesons wouldbe forbidden in thequark model, but wouldbe allowed by the StandardModel, the central theory ofmodern physics, as bound statesof both quarks and gluons.

Willutzki was the E852project manager and, eventu-ally, a co-spokesperson for theexperiment. His contributionshelped lead to a collection ofrich data, which resulted,among other observations, in

the discovery of two exotic me-son particles.

Willutzki’s colleague, Suh-Urk Chung, comments: “Hanshad a rare intuitive judgment ofwhat good physics should be,and everyone around himbenefited from his thoughtfulremarks.”

More recently, Will-utzki joined the BNL

team working on theD-Zero experimentat The Fermi Na-tional AcceleratorLaboratory, con-tributing signifi-cantly to the in-stallation of theupgraded detector

systems.Hans Willutzki was

a resident of Coram. Inhis memory, friends and col-leagues are gathering today, Fri-day, February 1, at 4:30 and 6:30p.m. in the Physics Departmentlounge area. Refreshments willbe served. If you plan to attend,notify Debbie Kerr, Ext. 3857 ordkerr@bnl.gov; or Bob Hacken-burg, Ext. 2088 or hacken-burg@bnl.gov as soon as pos-sible. — Liz Seubert

“No. Some are, but mostare not,” Meinhold replied.The biggest threat, he said,is panic. When a dirty bombgoes off, people could be soconcerned about contami-nation that they may notget the injured to medicalcare, he said.

First responders, theNightline segment and theNCRP report both remarkedupon, would receive thehighest concentration ofany radiation released froma dirty bomb and therefore,must be given the equip-ment and training to copewith the situation.

In discussing these issuesafter the TV appearance,Meinhold said that thepublic’s fear could be greatlyameliorated by making surethat first responders andother key personnel under-stand the potential dangersand how to deal with them.

MK2323. ASSISTANT SCIENTIST (S-1) �Requires a Ph.D. in cell biology or closelyrelated area and knowledge of DNA dam-age, recognition or repair in mammaliancells. Will develop a research program toidentify mechanisms by which mammaliancells detect and respond to DNA damageincluding damage caused by ionizing radia-

tion. Will collaborate with existing BiologyDepartment staff to identify the macromo-lecular components, including protein com-plexes, that detect DNA damage and thatconstitute signal transduction pathways lead-ing to control of cell cycle progression andthe repair of DNA damage, and to determinethe structure of these components and com-plexes at atomic resolution. Under the direc-tion of C. Anderson, Biology Department.

MK2345. POSTDOCTORAL RESEARCHASSOCIATE � Requires a Ph.D. in chem-istry and experience in electrochemistry andelectrocatalysis. Experience in electrochem-istry and electrocatalysis, and in-situ spec-troscopic studies desirable. Research will in-volve new method of synthesis and charac-terization of novel bimetallic electrocatalystsfor fuel cells with improved tolerance to COin reformate H
