HKUST physicists--Assistant Professors Zikang Tang and Ning Wang, and team--have synthesized the world's narrowest single-walled carbon nanotubes.
75,000 times thinner than a human hair
The ultra small carbon cylinders they have fabricated are only 4
Nanotube theory holds these to be the narrowest stable single-walled carbon nanotubes possible.
Before Profs Tang and Wang's breakthrough, the narrowest single-walled
nanotube fabricated measured 7
Novel fabrication technique
On top of their "first past the post" satisfaction, the team are excited about the success of their innovative fabrication technique.
"We suspected we had succeeded in growing 4
Why these 4
The zeolite crystal method produces arrays of single-walled carbon nanotubes that are highly aligned and uniform in size. This will be a boon for experimental investigation of their electrical and mechanical properties.
"We are already observing new properties in the 4
"In the longer term, nanotubes this small could revolutionize microcomputers and other ultra-thin electronic devices. Another exciting avenue of research is their suitability as a storage medium for pollution-free hydrogen fuel."
