Researchers at NJIT have developed a quick and simple method to produce water-soluble carbon nanotubes. They report that the new nanotubes are 125 times more water soluble than existing ones. In addition, the new nanotubes, following a short heat treatment, can conduct electricity as well as the non-soluble ones.

Read moreGeorgia Tech researchers have created a highly sensitive atomic force microscopy (AFM) technology capable of high-speed imaging 100 times faster than current AFM. This technology could prove invaluable for many types of nano-research, in particular for measuring microelectronic devices and observing fast biological interactions on the molecular scale, even translating into movies of molecular interactions in real time.

Read moreUntil now, scientists haven't properly understood why CNT are visible using a scanning electron microscope. Stanford engineers have solved the mystery, and its explanation not only could help researchers understand what they see in nanotube images but also suggests new nanotube applications such as ultra-sensitive detection of electrons and ultra-precise electron beams for microelectronics manufacturing.
