Nanodevices Get Connected

Hoping to one day shrink computer chips to vanishingly small proportions, researchers have been creating diodes and transistors on the scale of nanometers. They’ve even wired them into working circuits. Now, in the 21 November issue of Science, two teams report advances that could help propel nanocircuits from the realm … More

 

A Nano-Sized Ski Resort

Unsatisfied with a bar of Toblerone as a memento of the magnificent Matterhorn, researchers have crafted a highly detailed 3D glass replica of the Swiss mountain with a peak that is only 25 nanometers high—the smallest, most complex 3D structure that has ever been carved out of a material. The … More

 

Gold Nanostars for Attacking Cancer

Gold stars, so tiny that it would take a thousand of them to span the diameter of a human hair, could be effective tumor-fighters. Previous studies have shown that minuscule particles of metal or other materials, directed to a tumor and then manipulated by lasers or magnetic fields, can kill … More

 
Physicists have learned the main reason for the lack of graphene

Physicists have learned the main reason for the lack of graphene

Group of physicists led by Kirill Bolotin from Vanderbilt University were able to establish the cause of the low electron mobility in graphene. In addition, they were able to increase the rate of three. The results of their work published journal Nature Communications. The researchers placed a layer of graphene … More

 
The Spaniards created the most sensitive balance

The Spaniards created the most sensitive balance

Spanish physicists have created the most sensitive to date balance – they are able to measure the mass with an accuracy of 1.7 nm.  Article scientists appeared in Nature Nanotechnology. Libra is a carbon nanotube length of about 150 nm and diameter of 1.7 nm, placed in a vacuum chamber. … More

 
Silicon spheres help to create invisibility cloak

Silicon spheres help to create invisibility cloak

Silicon sphere with a diameter of 100-200 nanometers can serve constituents “bricks” invisibility cloak, which will be able to hide objects in visible light. Cloak – a well-established term applied to structures used for masking objects from electromagnetic waves. Normally masking is set up so that an electromagnetic wave, after … More

 
Physicists have created weighing individual protein molecules

Physicists have created weighing individual protein molecules

French physicists gathered microscopic scales of the four electrodes and connection to the vibrating plate is sensitive enough to measure the mass of individual protein chains, and issued “instructions” for assembly in the journal Nature Nanotechnology. The precise measurement of the mass of microscopic bodies, atoms and molecules is a … More

 
“Smart” coating for transparent surfaces inspired by lotus leaves

“Smart” coating for transparent surfaces inspired by lotus leaves

Chinese scientists have used nanoparticles of silica, resembling a raspberry and a cavity-berry, to create transparent water is repellent coatings for self-cleaning glass and other transparent surfaces. A lotus leaf inspired them, well known for its water-repellent properties, which are derived from the finest textured bumps that cover the surface. … More
