Engineers estimate that a gallon of EdenCrete admixture contains one quintillion--1 x [10.sup.18] or one million trillion--carbon nanotubes, shown in cement paste (below) at 76,200x magnification through a helium ion microscope
More than PS4m will be used to improve the university's National X-Ray Photoelectron Spectroscopy laboratory, including the purchase of a state-of-the-art Helium Ion Microscope
Helium Ion Microscope
(HIM) was used to study surface morphologies of these films before and after irradiation.
Oberkochen, Germany and Peabody, MA 7/19/06--Carl Zeiss SMT AG's Nanotechnology Systems Division has acquired ALIS, developer of the Looking Glass LG2 helium ion microscope
. "The Helium ion microscopy technology developed by ALIS complements our market leading scanning electron microscopy (SEM) technology and will be a key element of our future technology roadmap.
It features in situ alignment, combining ion and photon optical microscopes in a coaxial photon ion microscope
to support front-side and backside milling using through-silicon imaging.
The art of magnifying the small reached a new plateau in 1955 when the German-born American physicist Erwin Wilhelm Mueller, who had developed the field-emission microscope (see 1937), devised the field ion microscope
, which emitted beams of ions rather than electrons.
The newly developed ORION helium ion microscope
, from Carl Zeiss SMT, Peabody, Mass., addresses the present limitations of the SEM.
Using a field ion microscope
, they have managed to observe single iridium atoms settling into position on closely packed iridium planes, revealing, among other things, a previously unseen "empty zone" near the lattice's edge, Ehrlich said last week in Boston at a meeting of the Materials Research Society.
"Our scanning ion microscope
uses a beam of helium ions as the imaging particles," he adds.
