Microtubules, Motor Proteins And Nano-patterning

Two kinds of kinesin molecular motors have different properties of coordination, Kyoto University’s School of Engineering has found. The findings were made possible thanks to a new tool the team developed that parks individual motors on platforms thousands of times smaller than a single cell. “Kinesin is a motor protein that is involved in actions such as cell division, muscle contractions, and flagella movement. They move along these long protein filaments called microtubules. [Read More]

Water Inside Carbon Nanotubes Stays Frozen At Boiling Point

The action of water in carbon tubes at the nanometer scale was a surprise to researchers as well. Water, at sea level, starts to boil at a temperature of 212 degrees Fahrenheit, or 100 degrees Celsius. That much is well known. Scientists have also long known that when water is confined in very small spaces, its boiling and freezing points can change a bit, usually dropping by around 10 C or so. [Read More]

Carbon Nanotube to Gas Atoms Interaction Precisely Measured

Interaction occurring between atoms and molecules that constitute air, and the carbon surface used in battery electrodes and air filters has been measured at the most precise level yet by University of Washington physicists. The resulting data could be key information for improving technologies including batteries, electrodes and air filters. The team used a carbon nanotube as a transistor to study what happens when gas atoms come into contact with the nanotube’s surface. [Read More]

Carbon Nanotubes Coupled For Efficient Signal Transmission

A unique method that may enable efficient transmitting of signals from nanocomponents in electronic circuits has been developed by physicists at University of Basel. The method involoves an arrangemnt with a nanocomponent connected to two electrical conductors, which uncouple the electrical signal highly efficiently. The miniaturization of electronic components contunues to progress. Currently, components measuring just a few nanometers (the size of around ten atoms) are being produced in research labs.

Nanotube Graphene Spaser World’s First

The first ever spaser to be made completely of carbon has been modelled by researchers from Monash University. The technology could lead to mobile phones becoming so small, efficient, and flexible they could be printed on clothing. A spaser (an acronym for Surface Plasmon Amplification by Stimulated Emission of Radiation) is essentially a nanoscale laser or nanolaser. It emits a beam of light through the vibration of free electrons, instead of the space-consuming electromagnetic wave emission process of a traditional laser. [Read More]

New Nanotube Graphene Hybrid Material Easier to Handle

Reinforcing bars of carbon nanotubes make two-dimensional graphene much easier to handle, researchers at Rice University have found. The new hybrid, according to Rice chemist James Tour, could, when stacked in a few layers, make a cost-effective alternative for costly indium tin oxide (ITO). ITO is currently used in displays and solar cells. Tour set nanotubes into graphene in a way that is analogous to how steel rebar is used in concrete. [Read More]

Carbon Nanotube Flexible Circuits get Power Efficiency Boost

A team of researchers at Stanford has developed a technique to create flexible chips that can withstand power fluctuations in almost the same way as silicon circuits. Flexible electronic devices, like a smartphone that could be folded to fit into a pocket, are on the minds and drawing boards of many engineers these days. One approach being tried involves designing circuits based on flexible electronic fibers called carbon nanotubes, instead of stiff silicon chips. [Read More]

Graphene Oxide Carbon Fiber Makes Better Knots

A new type of carbon fiber containing large flakes of graphene oxide has been created at Rice University. The fiber is unique owing to the strength of its knots. Fibers are typically most likely to snap under tension at the location of the knot, but this new fiber has what the researchers call “100 percent knot efficiency,” meaning the fiber is as likely to fail anywhere along its length as at the knot.
