Statistical noise characterized in interactions of atoms with nanomachines

The interactions of xenon atoms with a nanoelectromechanical system have now been measured to characterize the statistical noise caused by atomic fluctuations.

Researchers use Nanofabrication Techniques to bring us closer to Quantum Computing

Nanofabrication methods were used to observe a rare state of matter known as a ‘half-quantum vortex’, which may bring a solution to the decoherence hurdle to quantum computing.

Nanotechnology device harvests wasted energy

An energy cell containing a lead zirconate titanate cantilever coated with a carbon nanotube film uses nanotechnology to produce electricity from scavenged light and thermal energy.

The worlds smallest snowman

The worlds smallest snowman. from nanowerk     The snowman is 10 µm across, 1/5th the width of a human hair. The snowman was made from two tin beads used to calibrate electron microscope astigmatism. The eyes and smile were milled using a focused ion beam, and the nose, which is under 1 µm wide,… Continue reading The worlds smallest snowman

IEEE Spectrum: Radios With Micromachined Resonators

IEEE Spectrum: Radios With Micromachined Resonators. It’s likely that better mechanical components, and the cognitive-radio techniques they enable, will usher in the next wave of mobile telephony by giving our cellphones access to much more spectrum. These phones will operate in multiple bands, provide greater data throughput, and minimize if not eliminate the need for… Continue reading IEEE Spectrum: Radios With Micromachined Resonators

Nanoscale Wear

One of the major problems for micromachines, much less nanomachines, is wear. The phenomenon of stiction combines the two worst aspects of surface-to-surface interaction — a high coefficient of friction and a locally-generated high applied force — to cause enormous problems. At the very smallest scale, once we gain complete control over atomic configuration, superlubricity… Continue reading Nanoscale Wear

Discovery of repulsive Casimir forces might eliminate friction as a concern in nanotechnology

A newly discovered repulsive quantum mechanical force could be useful for nanotech applications by enabling a type of quantum levitation.

Fast and precise control of AFM tips may enable nanotechnology memory devices

Arrays of atomic force probe tips are promising nanotech approaches to denser, faster, cheaper memories.

Calculating the role of Casimir forces in nanotechnology

Swedish scientists have developed a computer program to calculate Casimir forces between various types of nanostructured materials, which may help to determine whether significant friction problems exist in specific designs.
