New experimental test of buried contacts paves the way for molecular devices As electronics become smaller and smaller the need to understand nanoscale phenomena becomes greater and greater. Because materials exhibit different properties at the nanoscale than they do at larger scales, new techniques are required to understand and to exploit these new phenomena. A team of researchers led by Paul Weiss, UCLA's Fred Kavli Chair in NanoSystems Sciences, has developed a tool to study nanoscale...

To be useful in real-world applications, a self-assembled monolayer (SAM) of molecules on a surface must have a stable and controllable geometry. Researchers at Penn State and the Sigma-Aldrich company have found a way to control geometry and stability by making SAMs out of different carboranethiol isomers, which are cage-like molecules. The research results will be published in the March 2009 issue of the journal ACS Nano."Our results allow us to control the chemical and physical properties...

U.S. scientists say they have found a way to control the geometry and stability of a new family of self-assembled-monolayer materials called carboranes. The Pennsylvania State University researchers said the exceptionally high quality and simplicity of the improved carboranes opens up new capabilities in selective patterning and control, and new possibilities for applications. They said a tailored carborane film just one-nanometer or two-nanometers in height completely changes the chemical,...

19 August 2005 - Scientists will announce next month a new technique called microdisplacement printing, which makes possible the highly precise placement of molecules during the fabrication of nanoscale components for electronic and sensing devices. The new technique, which also extends the library of molecules that can be used for patterning, will be described in the 14 September issue of the journal Nano Letters by a team led by Paul S. Weiss, professor of chemistry and physics at Penn...

22 June 2005 - A team of chemists at Penn State has developed a new type of ultrathin film, which has unusual properties that could improve the fabrication of increasingly smaller and more intricate electronic and sensing devices. The material, a single layer made from spherical cages of carbon atoms, could enable more precise patterning of such devices with a wider range of molecular components than now is possible with conventional self-assembled monolayers. The research is published in the...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
