Texas, Aug. 26, 2004 -- Austin, Texas-based Nano-Proprietary,
Inc. (OTC BB:NNPP.OB - News), through its subsidiary,
Applied Nanotech, Inc. (ANI), have announced that
its U.S. Patent claiming two-dimensional carbon nanostructures
(dubbed by ANI ``carbon flakes''), with the priority
date of August 21, 2000, was allowed by the U.S. Patent
Office. These two-dimensional carbon nanotube structures,
which may also be referred to as carbon nanowalls,
may have attractive electron emission properties due
to their sharp edges. The large surface area of this
newly identified carbon phase may also make them particularly
useful in applications for chemical and bio-sensors.
Professor Yihong Wu of Kyoto University in Japan recently
announced that he had succeeded in growing and observing
a similar two-dimensional nano-structure (dubbed ``Carbon
Separately, ANI announced that its U.S. Patent No.
5,869,922 claiming specific UV Raman spectrum signatures
for all carbon films that have superior electron emission
properties was granted in South Korea as Patent No.
422244, with an effective date of February 22, 2004.
This intellectual property correlates superior electron
emission properties of carbon film in any form and
certain UV Raman Spectrum measurements.
The UV Raman spectrum analysis can be performed on
very small quantities of material and the patented
signature can be identified immediately. All carbon
films, including carbon nanotube films, used by ANI
for electron emission applications fall within the
UV Raman spectrum signatures claimed in the above
``These new patent developments, when combined with
our existing portfolio, further our dominance of any
applications where carbon is used as an electron emission
source,'' said Dr. Zvi Yaniv, Chief Executive Officer
of Applied Nanotech, Inc.
