Nanoscience may provide a way to engineer materials that are virtually defect-free – perfect, that is.


In new hybrid chip, molecules are memories

August 08, 2006 | User rating: 4.1 / 5 after 46 vote(s) | No comments yet

As scientists strive to satisfy the growing demand of the digital era for faster, smaller, and cheaper electronics, one of the most promising technologies is hybrids. Hybrid ICs (integrated circuits) consist ...


Scientists design simpler, more accurate nanothermometer

July 26, 2006 | User rating: 4.3 / 5 after 39 vote(s) | No comments yet

By using carbon nanotubes containing gallium for measuring temperature at the nanoscale, scientists have invented a new nanothermometer that works simply by heating and cooling the tubes.


Superheating Nanoparticles

July 24, 2006 | User rating: 4.3 / 5 after 31 vote(s) | No comments yet

“For quite a long time people have been measuring the melting points of small particles,” Shaun Hendy tells PhysOrg.com. “They’ve found that the melting point decreases and this decrease is in inverse proportion to ...


Nanoparticles self-assemble through chemical lithography

July 20, 2006 | User rating: 4.2 / 5 after 40 vote(s) | No comments yet

Nanoparticles – while possessing some amazing properties of strength and power – are also delicate little things, when it comes to manipulating them for use in nanodevices. Many scientists consider that the ...

A group of scientists from the National University of Singapore published a study in the May 30th issue of Nanotechnology, which developed polymer nanofiber membranes with a synthesized catalyst to detoxify nerve agents.


Electromechanical imaging in liquid environments: a pathway toward molecular-level resolution of biological systems

July 01, 2006 | User rating: 4.2 / 5 after 48 vote(s) | No comments yet

Scientists have demonstrated that electromechanical imaging techniques, when operated in a liquid environment, can provide a resolution of up to 10 times that of the resolution when imaging in air. The liquid ...


Nanocrystals' 'self-purification' mechanisms explained by energetics

June 21, 2006 | User rating: 4.4 / 5 after 54 vote(s) | No comments yet

Doping semiconductor nanocrystals will likely provide a basis for a wide variety of nano applications. But since the tiny nanocrystals tend to repel impurities, scientists must first find a way to overcome ...


Nano-tip could play integral part in heat-assisted data storage devices

June 09, 2006 | User rating: 4.3 / 5 after 49 vote(s) | No comments yet

Using a tip with a nano heat source that never touches the surface, scientists have shown how to heat a localized surface with no contact. The discovery could open the doors to heat-assisted data storage devices ...
