Ionenstrahlen werden schon lange eingesetzt, um Oberflächen zu verändern. Ionen können dabei so hohe Energien besitzen, dass bereits ein einziges Teilchen drastische Veränderungen auf der damit beschossenen Oberfläche hervorruft. Nach sorgfältigen Untersuchungen konnte das internationale Forschungsteam nun erklären, warum sich dabei manchmal Einschusskrater, in anderen Fällen hingegen Erhebungen bilden.
Diamondoids are nanoparticles made of only a handful of carbon atoms, arranged in the same way as in diamond, forming nanometer sized diamond crystals. Researchers have demonstrated the fascinating capability of these tiny little diamonds to act as a monochromator for electrons.
A Rice University laboratory has come up with a one-size-fits-almost-all way to measure batches of single-walled nanotubes that promises to help researchers and industry make more efficient use of the wondrous carbon material.
Imagine a computer chip that can assemble itself. According to Eric M. Furst, professor of chemical and biomolecular engineering at the University of Delaware, engineers and scientists are closer to making this and other scalable forms of nanotechnology a reality as a result of new milestones in using nanoparticles as building blocks in functional materials.
Erik Thostenson and Thomas Schumacher in University of Delaware's Center for Composite Materials have received a three-year $300,000 grant to investigate the use of carbon nanotube-based sensing composites for structural health monitoring of civil infrastructure.
U.S. Naval Research Laboratory electronics science and technology engineers demonstrate the ability of single walled carbon nanotube transistors (SWCNTs) to survive the harsh space environment, investigating the effects of ionizing radiation on the crystalline structures and further supporting the development of SWCNT-based nanoelectronics for use in harsh radiation environments.
Published by SAGE Publications, the Journal of Nanoengineering and Nanosystems is dedicated to the particular aspects of nanoscale engineering, science, and technology that involve the descriptions and characterizations of nanoscale systems and materials.
