A new study has found that “waviness” in forests of vertically-aligned carbon nanotubes dramatically reduces their stiffness, answering a long-standing question surrounding the tiny structures. Instead of being a detriment, the waviness may make the nanotube arrays more compliant and therefore useful as thermal interface material for conducting heat away from future high-powered integrated circuits.

Researchers from North Carolina State Univ. used airbrushing techniques to grow vertically aligned carbon nanofibers on several different metal substrates, opening the door for incorporating these nanofibers into gene delivery devices, sensors, batteries and other technologies.
A nanoparticle shaped like a spiky ball, with magnetic properties, has been uncovered in a new method of synthesizing carbon nanotubes by physicists in the U.K. The nanoparticles were discovered on the rough surfaces of a reactor designed to grow carbon nanotubes and are described as sea urchins because of their characteristic spiny appearance.
Measuring the band offset faced by electrons jumping from one material to another is a key component of a nanoscale design process because it guides redesign and prototyping.
