Rebranding the same old science!

Old Wine in a New Bottle?

What is nanoscience? Is it different from nanotechnology? Is it chemistry? Many chemists do think that nanoscience is another word for molecular chemistry. However, there are many who would argue with that definition (including the physicists, mechanical engineers, chemical engineers, bioengineers working in nanotechnology). Is molecular physics also nanoscience?

Though my own effort to understand nano science and technology over the last couple of years (as a journalist) and more so, after deciding to start the magazine, from last six months, has been that it is the same old science that Democritus, Rutherford, Rustom Roy, Milburn, etc have been talking about.

Hence I have been toying on the idea whether to ask this question or not… but after seeing the response that people have showered upon us for the blog, I assume I will get the answer!!!!

Best part that nano has brought in is that the youngsters think it is the most happening science and they are ready to show keen interest in this rather than “boring” chemistry and physics. By facing this happening tag to our good old science we are able to attract more kids to seriously take up nanotechnology!

What difference does the name make? Do kids seek out nano-related activities over more traditionally named activities? Or is this just rebranding of the same old science or is it something new? Can we make nanoscience something different?

If anyone has better way to explain nanotechnology please let me know. It would be of great help to understand….

Stanford writes in world’s smallest letters

Storing information in electron waves

The researchers encoded the letters “S” and “U” (as in Stanford University) within the interference patterns formed by quantum electron waves on the surface of a sliver of copper. The wave patterns even project a tiny hologram of the data, which can be viewed with a powerful microscope.

“We miniaturized their size so drastically that we ended up with the smallest writing in history,” said Hari Manoharan, the assistant professor of physics who directed the work of physics graduate student Chris Moon and other researchers.

The quest for small writing has played a role in the development of nanotechnology for 50 years, beginning decades before “nano” became a household word. During a now-legendary talk in 1959, the remarkable physicist Richard Feynman argued that there were no physical barriers preventing machines and circuitry from being shrunk drastically. He called his talk “There’s Plenty of Room at the Bottom.”

Feynman offered a $1,000 prize for anyone who could find a way to rewrite a page from an ordinary book in text 25,000 times smaller than the usual size (a scale at which the entire contents of the Encyclopedia Britannica would fit on the head of a pin). He held onto his money until 1985, when he mailed a check to Stanford grad student Tom Newman, who, working with electrical engineering Professor Fabian Pease, used electron beam lithography to engrave the opening page of Dickens’ A Tale of Two Cities in such small print that it could be read only with an electron microscope.

That record held until 1990, when researchers at a certain computer company famously spelled out the letters IBM by arranging 35 individual xenon atoms.

Now, in a paper published online in the journal Nature Nanotechnology, the Stanford researchers describe how they have created letters 40 times smaller than the original prize-winning effort and more than four times smaller than the IBM initials. (www.youtube.com/watch?v=j3QQJEHuefQ)

Working in a vibration-proof basement lab in the Varian Physics Building, Manoharan and Moon began their writing project with a scanning tunneling microscope, a device that not only sees objects at a very small scale but also can be used to move around individual atoms. The Stanford team used it to drag single carbon monoxide molecules into a desired pattern on a copper chip the size of a fingernail.

On the two-dimensional surface of the copper, electrons zip around, behaving as both particles and waves, bouncing off the carbon monoxide molecules the way ripples in a shallow pond might interact with stones placed in the water.

The ever-moving waves interact with the molecules and with each other to form standing “interference patterns” that vary with the placement of the molecules.

By altering the arrangement of the molecules, the researchers can create different waveforms, effectively encoding information for later retrieval. To encode and read out the data at unprecedented density, the scientists have devised a new technology, Electronic Quantum Holography.

In a traditional hologram, laser light is shined on a two-dimensional image and a ghostly 3-D object appears. In the new holography, the two-dimensional “molecular holograms” are illuminated not by laser light but by the electrons that are already in the copper in great abundance. The resulting “electronic object” can be read with the scanning tunneling microscope.

Several images can be stored in the same hologram, each created at a different electron wavelength. The researchers read them separately, like stacked pages of a book. The experience, Moon said, is roughly analogous to an optical hologram that shows one object when illuminated with red light and a different object in green light.

For Manoharan, the true significance of the work lies in storing more information in less space. “How densely can you encode information on a computer chip? The assumption has been that basically the ultimate limit is when one atom represents one bit, and then there’s no more room—in other words, that it’s impossible to scale down below the level of atoms.

“But in this experiment we’ve stored some 35 bits per electron to encode each letter. And we write the letters so small that the bits that comprise them are subatomic in size. So one bit per atom is no longer the limit for information density. There’s a grand new horizon below that, in the subatomic regime. Indeed, there’s even more room at the bottom than we ever imagined.”

In addition to Moon and Manoharan, authors of the Nature Nanotechnology paper, “Quantum Holographic Encoding in a Two-Dimensional Electron Gas,” are graduate students Laila Mattos, physics; Brian Foster, electrical engineering; and Gabriel Zeltzer, applied physics.

The research was supported by the Department of Energy through SLAC National Accelerator Laboratory and the Stanford Institute for Materials and Energy Science (SIMES), the Office of Naval Research, the National Science Foundation and the Stanford-IBM Center for Probing the Nanoscale.

Engines of Creation

Some more info on what Maju had to tell. This is path breaking book which paved way for research in nanotechnology. I thought I should share the below info about the book and also about the author:

Originally published in 1986, K. Eric Drexler’s Engines of Creation laid the theoretical foundation for the modern field of nanotechnology and articulated the amazing possibilities and dangers associated with engineering at the molecular scale. Unique for both its style and substance, the book is today recognized as the seminal work in nanotechnology and has earned Drexler the title of “Father of Nanotechnology.”

Engines of Creation 2.0: The Coming Era of Nanotechnology – Updated and Expanded, is an ebook-only version available for free to readers exclusively through WOWIO. In addition to an updated “look and feel” for the ebook, Engines of Creation 2.0 has been expanded to include the first known lecture on nanotechnology by physicist Richard Feynman, the landmark open letter debate between Dr. Drexler and the late nanotech pioneer and Nobel laureate Dr. Richard Smalley, analysis of the debate by Ray Kurzweil, and a number of new additions by Dr. Drexler, including his advice to aspiring nanotechnologists.

K. Eric Drexler is often described as the ‘father of nanotechnology’. In 1981, he outlined an approach to implementing productive nanosystems in a paper published in the Proceedings of the National Academy of Sciences. This paper established fundamental principles of molecular design, protein engineering, and many areas of nanotechnology. Drexler’s theoretical research in this field has been the basis for numerous journal articles and books including Engines of Creation and Nanosystems: Molecular Machinery, Manufacturing, and Computation. Drexler founded the Foresight Institute, a non-profit organization focused on nanotechnology and served as Chairman until his departure in 2003. He is presently Chief Technical Advisor to Nanorex, a company developing design software for molecular engineering. Drexler was awarded a PhD from the Massachusetts Institute of Technology in Molecular Nanotechnology (the first degree of its kind).
