America\u2019s first plutonium implosion test\u2014its first detonated nuclear bomb\u2014left the 100-foot (30-meter) tower that held it aloft, including all its copper wire, copper sheathing, and coaxial cables, completely vaporized<\/a>.<\/p>\n

Almost instantaneously, the 21-kiloton fireball erupted into the New Mexico sky as Robert Oppenheimer initiated the July 16, 1945, Trinity test. The blast exposed the tower\u2019s aerosolized metals and the sandstone desert dust beneath them to temperatures in excess of 2,732 degrees Fahrenheit (1,500 degrees Celsius). The pressure on these elements, roughly one million pounds per square inch, rivaled the pressures bearing down on rocks hundreds of miles underground where the Earth\u2019s crust presses into its mantle.<\/p>\n

Small wonder, then, that physicists, geologists, and other researchers are still finding radical reconfigurations of the desert Southwest\u2019s basic chemical makeup<\/a> over 80 years later in what was once the Manhattan Project\u2019s Alamogordo Bombing Range.<\/p>\n

Now physicists in Europe and the United States have uncovered what they describe<\/a> as a \u201cpreviously unknown crystalline phase\u201d of a type of compound, called a clathrate, composed of silicon, calcium, iron, and some of that copper evaporated by Trinity\u2019s historic blast. Like other clathrates, this Trinity site crystal forms a complex geometric latticework capable of storing other smaller molecules or atoms like a nanoscale cage.<\/p>\n

The discovery, as the new study\u2019s lead author, Italian geologist Luca Bindi, and his colleagues wrote, \u201crepresents the first crystallographically confirmed identification of a clathrate structure among the solid-state products of a nuclear explosion.\u201d The discovery could deepen our understanding of these valuable crystalline compounds, the researchers said.<\/p>\n

Crystal chemistry <\/p>\n

Material scientists prize clathrates for their utility in myriad high-tech applications. These crystals can, for example, act like little parking garages storing<\/a> the lithium ions within lithium-ion batteries, both at the beginning and end of charging and discharging cycles. And, across industries, clathrates have helped engineers tailor highly bespoke silicon compounds, implanted or \u201cdoped<\/a>\u201d with elements whose specific electrical, magnetic, or catalytic properties can enhance solar<\/a> cells, quantum<\/a> computers, and countless other<\/a> innovative devices<\/a>.<\/p>\n

\u201cMore broadly,\u201d as Bindi and his coauthors put<\/a> it in their new study, \u201cthis work underscores how rare, high-energy events\u2014such as nuclear detonations, lightning strikes, and hypervelocity impacts\u2014serve as natural laboratories for producing unexpected crystalline matter.\u201d<\/p>\n

The newly discovered clathrate crystal will also help scientists better model and predict how these complex molecular geometries form by serving as a truly nuclear edge case, one \u201cbeyond the reach of conventional synthesis,\u201d they wrote in the study.<\/p>\n

The researchers found this previously unknown clathrate inside red trinitite, a rare fragment of glassed sand produced by the Trinity bomb.<\/p>\n

\u201cWhile the majority of trinitite exhibits a characteristic pale green color,\u201d the researchers note, \u201ca less common variety\u2014red trinitite\u2014is enriched in metals derived from the vaporized tower, coaxial cables, and recording instruments.\u201d<\/p>\n

Bindi, the chair of mineralogy and crystallography at the University of Florence in Italy, worked with physicists at Princeton, Carnegie Mellon, and the Slovak Academy of Sciences to subject this clathrate material to highly detailed single-crystal X-ray diffraction analysis to map its 3D geometry. They then experimented with the clathrates\u2019 quite literally multifaceted geometric structure\u2014its dodecahedral (12-faced) and tetrakaidecahedral (14-faced) silicon cages\u2014to determine whether it could be related to another unusual quasicrystal they found<\/a> at the Trinity site in 2021.<\/p>\n

While the researchers could not determine a relationship between these two unusual compounds forged by the nuclear blast, they noted that many unusual and still undiscovered compounds exist inside the site\u2019s red trinitite, waiting to be compared and contrasted.<\/p>\n

\u201cSystematic investigation of metallic droplets in red trinitite has revealed a range of unusual phases,\u201d Bindi and his coauthors noted in the study, \u201creflecting the unique chemical environments produced during the explosion.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"America\u2019s first plutonium implosion test\u2014its first detonated nuclear bomb\u2014left the 100-foot (30-meter) tower that held it aloft, including…\n","protected":false},"author":3,"featured_media":789554,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[8],"tags":[112541,43588,5160,375,159,67,132,68],"class_list":["post-789553","post","type-post","status-publish","format-standard","has-post-thumbnail","category-science","tag-crystals","tag-manhattan-project","tag-material-science","tag-nuclear-weapons","tag-science","tag-united-states","tag-unitedstates","tag-us"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@us\/116557984083665815","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/789553","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/comments?post=789553"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/789553\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media\/789554"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media?parent=789553"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/categories?post=789553"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/tags?post=789553"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
