Self-assembled superlattices create molecular machines with 'hinges' and 'gears'

08-04-2014

A combined computational and experimental study of self-assembled silver-based structures known as superlattices has revealed an unusual and unexpected behavior: arrays of gear-like molecular-scale machines that rotate in unison when pressure is applied to them. Computational and experimental ...

Heat-conducting polymer cools hot electronic devices at 200 degrees C

01-04-2014

Polymer materials are usually thermal insulators. But by harnessing an electropolymerization process to produce aligned arrays of polymer nanofibers, researchers have developed a thermal interface material able to conduct heat 20 times better than the original polymer. The modified material can ...

Biofuel alternative for high-energy rocket fuel

28-03-2014

Researchers at the Georgia Institute of Technology and the Joint BioEnergy Institute have engineered a bacterium to synthesize pinene, a hydrocarbon produced by trees that could potentially replace high-energy fuels, such as JP-10, in missiles and other aerospace applications. With improvements ...

Solar-induced hybrid fuel cell produces electricity directly from biomass

20-02-2014

Although low temperature fuel cells powered by methanol or hydrogen have been well studied, existing low temperature fuel cell technologies cannot directly use biomass as a fuel because of the lack of an effective catalyst system for polymeric materials. Now, researchers at the Georgia Institute ...

A 21st century adaptation of the Miller-Urey origin of life experiments

A safe approach to investigating how organic molecules could come about from inorganic compounds

23-01-2014

The Journal of Visualized Experiments published a modern approach to a famed experiment that explored one of the most intriguing research questions facing scientists today—the origin of life on earth. The protocol, titled Conducting Miller-Urey Experiments, is comprised of a modern and simplified ...

Tiny bottles and melting corks

Temperature regulates a new delivery system for drugs and fragrances

23-09-2013

Microscopic, bottle-like structures with corks that melt at precisely-controlled temperatures could potentially release drugs inside the body or fragrances onto the skin, according to a recently published study. Typical drug delivery systems act more like sponges than bottles. For example, drugs ...

Glass or plastic?

Container's material properties affect the viscosity of water at the nanoscale

23-09-2013

Water pours into a cup at about the same rate regardless of whether the water bottle is made of glass or plastic. But at nanometer-size scales for water and potentially other fluids, whether the container is made of glass or plastic does make a significant difference. A new study shows that in ...

Control scheme dynamically maintains unstable quantum system

02-09-2013

A simple pendulum has two equilibrium points: hanging in the "down" position and perfectly inverted in the "up" position. While the "down" position is a stable equilibrium, the inverted position is definitely not stable. Any infinitesimal deviation from perfectly inverted is enough to cause the ...

The role of goop: Research shows pollution doesn't change the rate of droplet formation

20-02-2013

When it comes to forming the droplets that make up clouds, a little oily and viscous organic material apparently doesn't matter that much. And that's good news for reducing the uncertainty of climate model predictions. Understanding cloud formation is essential for accurate climate modeling, and ...

Pyroelectric nanogenerator charges Li-ion battery with harvested energy

26-11-2012

The idea of harvesting ambient energy from the environment that would otherwise not be purposefully used is, in theory, a great way to produce green, renewable energy. But the biggest problem in this fairly new area of research is that scientists have yet to find a method that can harvest very ...
