 At just a molecule thick, it’s a new record: The world’s thinnest sheet of glass, a serendipitous discovery by scientists at Cornell and Germany’s University of Ulm, is recorded for posterity in the Guinness Book of World Records. 
  
 The “pane” of glass, so impossibly thin that its individual silicon and oxygen atoms are clearly visible via electron microscopy, was identified in the lab of David A. Muller, professor of applied and engineering physics and director of the Kavli Institute at Cornell for Nanoscale Science. 
  
 The work that describes direct imaging of this thin glass was published in January 2012 in Nano Letters, and the Guinness records officials took note. They published the achievement in early September for inclusion in the 2014 book, and the breakthrough is featured in the publication’s 21st Century Science spread. 
  
 Just two atoms in thickness, making it literally two-dimensional, the glass was an accidental discovery, Muller said. The scientists had been making graphene, a two-dimensional sheet of carbon atoms in a chicken wire crystal formation, on copper foils in a quartz furnace. They noticed some “muck” on the graphene, and upon further inspection, found it to be composed of the elements of everyday glass – silicon and oxygen.

 They concluded that an air leak had caused the copper to react with the quartz, also made of silicon and oxygen. This produced the glass layer on the would-be pure graphene. 
  
 Besides its sheer novelty, Muller continued, the work answers an 80-year-old question about the fundamental structure of glass. Scientists, with no way to directly see it, had struggled to understand it: It behaves like a solid but was thought to look more like a liquid. 
  
 Now, the Cornell scientists have produced a picture of individual atoms of glass, and they found it strikingly resembles a diagram drawn in 1932 by W.H. Zachariasen – a longstanding theoretical representation of the arrangement of atoms in glass. 
  
 “This is the work that, when I look back at my career, I will be most proud of,” Muller said. “It’s the first time that anyone has been able to see the arrangement of atoms in a glass.” 
  
 What’s more, two-dimensional glass could someday find a use in transistors, by providing a defect-free, ultra-thin material that could improve, for example, the performance of processors in computers and smartphones. 
  
 The paper, “Direct Imaging of a Two-Dimensional Silica Glass on Graphene,” was published in Nano Letters on Jan. 23, 2012, with first authors Pinshane Huang, a Cornell graduate student, and Simon Kurash, a University of Ulm graduate student. It includes collaborators from the University of Ulm, Germany; the Max Planck institute for Solid State Research in Germany; University of Vienna; University of Helsinki; and Aalto University in Finland.

 Researchers accidentally discovered the world's thinnest sheet of glass, just two atoms thick. 
  
 Their chance finding — now immortalized in the 2014 edition of the Guinness Book of World Records, out this week — gives scientists a glimpse into the puzzling properties of glass, which behaves like both a solid and a liquid.

 Using an electron microscope, the researchers inspected some "muck" on the graphene, finding that it was essentially a 2D sheet of common glass, made up of silicon and oxygen atoms. 
  
 The glass layer likely was created when an air leak caused copper foils, which are involved in the graphene-making process, to react with a furnace made up quartz, a mineral that is comprised of silicon and oxygen, the researchers say. 
  
 The researchers' observations were first described in January 2012 in the journal Nano Letters. They say their microscopic photos of the ultra-thin pane may help to solve some long-standing uncertainties about glass, which is not exactly a liquid or a solid. 
  
 Most solids when they cool arrange their atoms in a rigid lattice. Though glass is hard and has a solid appearance, atoms that make up glass are arranged in a disordered network, more like a liquid. 
  
 The structure of the 2D glass that the Cornell researchers saw is similar to theoretical models of the irregular structure of glass dating back to the 1930s. 
  
 "This is the work that, when I look back at my career, I will be most proud of," David Muller, professor of applied and engineering physics at Cornell, said in a statement. "It's the first time that anyone has been able to see the arrangement of atoms in a glass." 
  
 Though it was an accidental discovery, the researchers say such deliberately created 2D glass could find its way into nanotechnology and could even one day be used in transistors.

 Scientists from Cornell University and the University of Ulm in Germany happened upon a world record-setting discovery. 
  
 A stroke of good luck led scientists to find the world’s thinnest piece of glass, measuring only two atoms thick. The glass was understandably easy to miss and was only seen when viewed through an electron microscope. 
  
 The scientists called the team from Guinness World Records, which titled their discovery ‘World’s Thinnest Glass.’ The scientists had actually been working to create a pure form of graphene, but one thing led to another and they found they had, instead, created an extremely thin film of glass. 
  
 More than a happy accident, the team can now examine this film of glass to better understand two-dimensional crystals in glass, something which has rarely been studied. 
  
 The glass was first discovered when they noticed a layer of what they call “muck” where they had been producing graphene. Putting the layer under an electron microscope, the scientists noticed the two-dimensional crystals resembled glass made of silicon and oxygen. 
  
 “In stark contrast with two-dimensional crystals such as graphene and monolayer hexagonal boron nitride, 2D glasses remain almost completely unexplored,” reads the corresponding paper for Cornell. “These materials, particularly if they cane [sic] isolated from substrates and free manipulated, may have enormous applicability.” 
  
 The American and German scientists scored another first as well; the images they took to record the moment are the first ever to show this arrangement of atoms that make up the glass. They believe the accident occurred when air reacted with some copper foils used in the graphene process and a quartz furnace. 
  
 As it turns out, one other man nearly discovered this two-dimensional and incredibly thin glass in 1932. According to the researchers, physicist William Houlder Zachariassen nearly categorized this arrangement of atoms in his research. The team says their images of the two-atom-thin glass closely resemble Zachariassen’s cartoon models of 2D continuous network glasses. 
  
 The team will now begin researching how these thin layers of glass are mapped out, why they exist, and how they can be used in future applications. So far they suggest this two-dimensional glass and others like it could be used in devices that use layers of graphene. 
  
 “Because the silica glass can be easily removed from the copper substrate and contains no dangling bonds, it may also find application in semiconductor or layered graphene electronics as a passivated starting layer for gate insulators,” write the scientists. ||||| A new record for the world's thinnest sheet of glass has been set, and it comes in at just two atoms thick. The ultra-thin glass, now recognized by the Guinness Book of World Records, was an accidental discovery by scientists at Cornell University and Germany’s University of Ulm. As they were working to produce pure graphene, the researchers noticed a formation of "muck," but closer analysis revealed a glass layer composed of silicon and oxygen. In other words, this major discovery was something of a stroke of luck. Scientists suspect that an air leak prompted a reaction between copper foils being used for the graphene work and a quartz furnace. 
  
 And despite the glass pane's barely-there size, it's providing scientists with a wealth of new insight on the core structure of glass. Using electron microscopy, they've produced a picture revealing the precise arrangement of atoms in glass, another first according to David A. Muller (whose lab made the discovery). Being afforded this opportunity for close inspection led scientists to another surprise; it turns out that physicist William Houlder Zachariasen came "startlingly" close to mapping out the correct arrangement way back in 1932. As for what implications this two-dimensional glass holds for the real world, experts say it could be one day be used in transistors and ultimately help speed up processing in computers and smartphones. The new glass record will be published in the 2014 edition Guinness book. |||||

It's another one of those chance scientific breakthroughs: Scientists from Cornell and Germany have created the thinnest glass known to man entirely by accident, reports LiveScience. Just how thin? A hard-to-fathom 2 atoms thick, which means you'll need an electron microscope to check it out, notes RedOrbit. The discovery might not only shed important insights into the unusual liquid-vs-solid structure of glass, it earned the scientists some real-world bragging rights: Guinness World Records has included the discovery in its 2014 book. So how did they create the glass? As the Cornell Chronicle explains, the scientists were making a different uber-thin material called graphine and noticed some "muck" on it. That muck turned out to be made of silicon and oxygen, the stuff of glass. Their best guess is that an air leak caused copper foils to react with a quartz furnace. By studying the happy accident, the researchers have for the first time revealed "the precise arrangement of atoms in glass," explains the Verge. Amazingly, it's nearly spot-on with a theoretical model drawn in 1932 by physicist WH Zachariasen. As for real-world applications, the 2D glass could someday be used in transistors and lead to faster processors for computers and smartphones.
