Chemists at the University of Illinois have created a simple and inexpensive molecular technique that replaces an expensive atomic force microscope for studying what happens to small molecules when they are stretched or compressed.The researchers use stiff stilbene, a small, inert structure, as a molecular force probe to generate well-defined forces on various molecules, atom by atom."By pulling on different pairs of atoms, we can explore what happens when we stretch a molecule in different...

University of Illinois scientists say they have created a simple technique for studying what happens to small molecules when they are stretched or compressed. The researchers said with stiff stilbene as a molecular force probe to generate well-defined forces on various molecules, atom by atom, they can observe what is widely otherwise observed only by using expensive atomic force microscopes. By pulling on different pairs of atoms, we can explore what happens when we stretch a molecule in...


Word of the Day
barghest
  • A goblin in English folklore, often appearing in the shape of a large dog and believed to portend imminent death or misfortune.
  • A ghost, wraith, hobgoblin, elf, or spirit.
The origin of 'barghest' is not known, but it may be from perhaps burh-ghest, town-ghost, or German Berg-geist (mountain spirit) or Bär-geist (bear-spirit).
