- Polymer opal films shed new kind of light on nature
07-23-2007 · EurekAlert!
Imagine cleaning out your refrigerator and being able to tell at a glance whether perishable food items have spoiled, because the packaging has changed color, or being able to tell if your dollar bill is counterfeit by stretching it to see if it changes hue. These are two commercial applications for a new type of flexible plastic film, developed by scientists at the University of Southampton in the United Kingdom and Darmstadt in Germany.

- Measurements from the edge: magnetic properties of thin films
09-28-2007 · EurekAlert!
Materials researchers at NIST, together with colleagues from IBM and the Massachusetts Institute of Technology, have pushed the measurement of thin films to the edge -- literally -- to produce the first data on how the edges of metallic thin films contribute to their magnetic properties. Their results may impact the design of future nanoscale electronics.

- UD scientists discover new class of polymers
01-02-2007 · EurekAlert!
For years, polymer chemistry textbooks have stated that a whole class of little molecules called 1,2-disubstituted ethylenes could not be transformed into polymers -- the stuff of which plastics and other materials are made.However, UD scientists Chris Snively and Jochen Lauterbach were determined to prove the textbooks wrong. As a result of their persistence, the researchers have discovered a new class of ultra-thin polymer films with potential applications ranging from coating tiny microelectronic devices to plastic solar cells.

- NRL scientists produce carbon nanotubes using commercially available polymeric resins
02-07-2008 · EurekAlert!
Scientists at the Naval Research Laboratory have successfully produced carbon nanotubes in high yields in bulk solid compositions using commercially available aromatic containing resins. The concentration of multi-walled carbon nanotubes and metal nanoparticles can be easily varied within the shaped carbonaceous solid. Carbon nanotube containing fibers and films have also been formulated from the precursor compositions. The potential range of applications is huge, including structure, energy, sensors, separation/filtration, battery, electronic displays and nanoelectronic devices.

- Smart thin film membranes adopt properties of guest molecules
03-28-2007 · EurekAlert!
Virginia Tech researchers announced last year that they had created a nanostructured membrane that incorporates DNA base pairs in order to impart molecular recognition and binding ability to the synthetic material. This year they will show for the first time that these new films, membranes, and elastomers are compatible with diverse organic and inorganic molecules and will adopt properties of the guest molecules.

- NIST imaging system maps nanomechanical properties
12-12-2007 · EurekAlert!
NIST has developed an imaging system that quickly maps the mechanical properties of materials -- how stiff or stretchy they are, for example -- at scales on the order of billionths of a meter. The new tool can be a cost-effective way to design and characterize mixed nanoscale materials such as composites or thin-film structures.

- Microgrid Allows Simultaneous Study of Multiple Variables
10-10-2007 · Brookhaven National Laboratory
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a method for correlating the results of microscopic imaging techniques in a way that could lead to improved understanding, diagnosis, and possibly treatment of a variety of disease conditions, including Alzheimer's disease. The Laboratory has filed a U.S. provisional patent application for the invention.
