Nanotechnology's new darling: graphene

For nanotechnology watchers who are experiencing nanotube fatigue, Scientific American recaps a newer nanotech material capturing the imagination: Called graphene, it is essentially a nanotube unrolled—a single layer of atoms arranged like a honeycomb. The difference may sound cosmetic, but when the goal is manipulating things that are a few atoms thick, going from tube… Continue reading Nanotechnology's new darling: graphene

Power system invented for nanotechnology

Since the concept of nanosystems first arose, people have asked “how will these things be powered?” Now there’s another answer from Z.L. Wang at Georgia Tech, in a paper published April 6 in Science. Extremetech explains: The generators use a series of vertically aligned zinc oxide nanowires that move inside a zigzag plate electrode. These… Continue reading Power system invented for nanotechnology

Nanotechnology patent problems blamed on unionization

Small Times reports on a meeting held in Oregon among a wide variety of nanotechnology-based business participants, at which many commercialization challenges were discussed. One was difficulties encountered with the U.S. Patent office: Start-ups expressed frustration with the U.S. Patent and Trademark Office (USPTO). Long waits for patent award decisions make it difficult for them… Continue reading Nanotechnology patent problems blamed on unionization

Nanotechnology "nanofactories" may not be far away

Gazette.net reports that nanotechnology is bringing dramatic advances: Imagine not having to go to the doctor when you are sick. No medicine, no popping pills. Instead, tiny cell-like machines in your body would already be at work manufacturing medicine and delivering it exactly where it is needed. University of Maryland researchers say these ‘‘nanofactories” may… Continue reading Nanotechnology "nanofactories" may not be far away

Open source security for nanotechnology

In the long term, we’ll need effective security techniques for advanced nanotechnology-based systems. This will take a while to figure out, so come help us do it at an upcoming open source conference, Penguicon: Open Source-style Security for the Whole Physical World Christine Peterson, Bruce Schneier One of the biggest problems society faces this century… Continue reading Open source security for nanotechnology

Massive nanotechnology review resolves hard/soft dispute

Here on Nanodot we mentioned earlier a nanotechnology survey article titled Synthetic Molecular Motors and Mechanical Machines by Euan Kay, David Leigh, and Francesco Zerbetto. I have a paper copy now and have to admit that it is indeed worth $25, but that the 24-hour online access offered by the publisher at that price would… Continue reading Massive nanotechnology review resolves hard/soft dispute

Visualizing nanotechnology in context

It’s hard for us macroscale beings to get a gut feel for the extreme size differences between, say, ourselves and nanoscale objects. The old “Powers of Ten” illustrations helped, but now there’s a new online version from Nikon called Universcale, which shows from 1026 to 10-15 meters. One billionth is such an unimaginable, unrealistic smallness.… Continue reading Visualizing nanotechnology in context
