ZURICH and SAN JOSE, Calif., April 23 /PRNewswire-FirstCall/ -- IBM (NYSE: IBM) scientists have created a 3D map of the earth so small that 1,000 of them could fit on one grain of salt.* The scientists accomplished this through a new, breakthrough technique that uses a tiny, silicon tip with a sharp apex -- 100,000 times smaller than a sharpened pencil -- to create patterns and structures as small as 15 nanometers at greatly reduced cost and complexity. This patterning technique opens new...

Researchers from the National Institute of Standards and Technology (NIST) and the Naval Research Laboratory have developed a new way to introduce magnetic impurities in a semiconductor crystal by prodding it with a scanning tunneling microscope (STM). Detailed in a recent paper,* this technique will enable researchers to selectively implant atoms in a crystal one at a time to learn about its electrical and magnetic properties on the atomic scale. A better understanding of these properties is...

SAN JOSE, Calif., Sept. 28 /PRNewswire-FirstCall/ -- On this day in 1989, IBM Fellow Don Eigler became the first person in history to move and control an individual atom. Shortly thereafter, on November 11 of that year, Eigler and his team used a custom-built microscope to spell out the letters IBM (NYSE: IBM) with 35 xenon atoms. This unprecedented ability to manipulate individual atoms signaled a quantum leap forward in nanoscience experimentation and heralded in the age of...

IBM scientists in Switzerland say they've become the first researchers to obtain a high resolution image of the chemical structure of an individual molecule. The scientists said they achieved the unprecedented resolution using non-contact atomic force microscopy, marking a milestone in surface microscopy and advancing exploration of electronic building blocks on the ultimate atomic and molecular scale. Although progress has been made in the characterization of nanostructures on the atomic...

Storing information in electron waves Stanford researchers have reclaimed bragging rights for creating the world's smallest writing, a distinction the university first gained in 1985 and lost in 1990. How small is the writing? The letters in the words are assembled from subatomic sized bits as small as 0.3 nanometers, or roughly one third of a billionth of a meter. The researchers encoded the letters "S" and "U" (as in Stanford University) within the interference patterns formed by quantum...

AMES, Iowa -- A genius well ahead of his time, Leonardo Da Vinci continues to inspire even 500 years after his remarkable life. His works are central to the best selling mystery novel The Da Vinci Code and its upcoming film adaptation, and his theories on friction are helping a group of scientists from the U.S. Department of Energy's Ames Laboratory and Lawrence Berkeley National Laboratory unlock the mystery of friction at the molecular level. In a nutshell, Da Vinci proposed that if...

BERKELEY, CA "“ The Da Vinci Code, the best selling novel and soon-to-be-blockbuster film, may also be linked some day to the solving of a scientific mystery as old as Leonardo Da Vinci himself "” friction. A collaboration of scientists from Lawrence Berkeley National Laboratory (Berkeley Lab) and the Ames Laboratory at Iowa State University have used Da Vinci's principles of friction and the geometric oddities known as quasicrystals to open a new pathway towards a better...

Not only were images of test patterns (lines formed by layers of chromium and silicon in cross-section) sharper than those made with the XM-1's current 25-nanometer-resolution MZP, the new MZP was able to obtain sharp images of lines a mere 15 nanometers apart "” where the older zone plate had seen only a featureless field of gray. "Nanoscience and nanotechnology are everywhere around us "” biology and chemistry are nanoscience by nature "” but we need better analytical...
