Nanotubes to equip ceramic coatings with heat radiation control

Researchers have engineered ceramic nanotubes that behave as thermal antennas, offering control over the spectrum and direction of high-temperature heat radiation.

Clean carbon nanotubes with superb properties

Scientists have found a new way to make ultra-clean carbon nanotube transistors with superior semiconducting properties.

Economizing on iridium for electrodes

Iridium is an ideal catalyst for the electrolytic production of hydrogen from water - but it is extremely expensive. But now a new kind of electrode made of highly porous material does an excellent job with just a hint of iridium.

New nanoscale technology shown to inhibit development of Alzheimer's disease

Researchers have developed nanoscale silicon chips for direct insertion of neural growth factor into the brain and its release into the target tissue.

A remote control for everything small

Atoms, molecules or even living cells can be manipulated with light beams. Researchers developed a method to revolutionize such 'optical tweezers'.

Atoms don't like jumping rope

Nanooptical traps are a promising building block for quantum technologies. Scientists have now removed an important obstacle to their practical use. They were able to show that a special form of mechanical vibration heats trapped particles in a very short time and knocks them out of the trap.
