Silicon nanowires are attracting significant attention from the electronics industry due to the drive for ever-smaller electronic devices, from cell phones to computers. The operation of these future devices, and a wide array of additional applications, will depend on the mechanical properties of these nanowires. New research from North Carolina State University shows that silicon nanowires are far more resilient than their larger counterparts, a finding that could pave the way for smaller,...

Study links size, activity, electronic properties University of Utah chemists demonstrated the first conclusive link between the size of catalyst particles on a solid surface, their electronic properties and their ability to speed chemical reactions. The study is a step toward the goal of designing cheaper, more efficient catalysts to increase energy production, reduce Earth-warming gases and manufacture a wide variety of goods from medicines to gasoline. Catalysts are substances that speed...

Put new wrinkle in old approach Harvard materials scientists have come up with what they believe is a new way to model the formation of glasses, a type of amorphous solid that includes common window glass. Glasses form through the process of vitrification, in which a glass-forming liquid cools and slowly becomes a solid whose molecules, though they've stopped moving, are not permanently locked into a crystal structure. Instead, they're more like a liquid that has merely stopped flowing,...

A gold nanocage covered with a polymer is a smart drug delivery system In campy old movies, Lucretia Borgia swans around emptying powder from her ring into wine glasses carelessly left unattended. The poison ring is usually a confection of gold filigree holding a cabochon or faceted gemstone that can be broken to empty the ring's contents. It is invariably enormous "” so large it is rather odd nobody seems to notice it. Lucretia would have given her eyeteeth for the "smart capsule"...

A team of engineers from the University of Pennsylvania has transformed simple nanowires into reconfigurable materials and circuits, demonstrating a novel, self-assembling method for chemically creating nanoscale structures that are not possible to grow or obtain otherwise. The research team, using only chemical reactants, transformed semiconducting nanowires into a variety of useful, nanoscale materials including nanoscale metal strips with periodic stripes and semiconducting patterns,...

Small bits of metal may play a new role in solar power. Researchers at Ohio State University are experimenting with polymer semiconductors that absorb the sun's energy and generate electricity. The goal: lighter, cheaper, and more-flexible solar cells. They have now discovered that adding tiny bits of silver to the plastic boosts the materials' electrical current generation. Paul Berger, professor of electrical and computer engineering and professor of physics at Ohio State, led the team that...


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
This word comes from the Latin 'coenobium,' convent, which comes from the Greek 'koinobios,' living in community.
