Graphene Combined with Silver Nanowires to Form Thin, Transparent and Stretchable Electrode

A hybrid transparent and stretchable electrode could open the new way for flexible displays, solar cells, and even electronic devices fitted on a curvature substrate such as soft eye contact lenses, by the UNIST(Ulsan National Institute of Science and Technology) research team.

Researchers Construct Polymer Opals from Spherical Nanoparticles

Instead of through pigments, these ‘polymer opals’ get their colour from their internal structure alone, resulting in pure colour which does not run or fade. The materials could be used to replace the toxic dyes used in the textile industry, or as a security application, making banknotes harder to forge. Additionally, the thin, flexible material changes colour when force is exerted on it, which could have potential use in sensing applications by indicating the amount of strain placed on the material.

Block Copolymer-Based PV Devices May Lead to New Class of Solar Energy Devices

A new version of solar cells created by laboratories at Rice and Pennsylvania State universities could open the door to research on a new class of solar energy devices.

Spherical Nanoparticles Form Netlike Structures When Encountered by Cancerous Tumors

Scientists at the University of California, San Diego, have designed tiny spherical particles to float easily through the bloodstream after injection, then assemble into a durable scaffold within diseased tissue. An enzyme produced by a specific type of tumor can trigger the transformation of the spheres into netlike structures that accumulate at the site of a cancer, the team reports in the journal Advanced Materials this week.

Nano-Scale Analysis Explains Difference between Glass and Molten Materials

Many solids are produced from melting. Depending on how quickly they cool off, invariably, internal tensile stresses begin to build up. One example are Prince Rupert's Drops, or Dutch tears: you can hit their thick end with a hammer without breaking them while a slight pressure applied to their thin end is enough to shatter the entire tear.

Study Evaluates Impact of Nanotechnology Innovation for Improving Electric Vehicle Li-ion Batteries

Lithium (Li-ion) batteries used to power plug-in hybrid and electric vehicles show overall promise to “fuel” these vehicles and reduce greenhouse gas emissions, but there are areas for improvement to reduce possible environmental and public health impacts, according to a “cradle to grave” study of advanced Li-ion batteries recently completed by Abt Associates for the U.S. Environmental Protection Agency (EPA).

Study Reveals Impact of Nano-Structured Catalyst Design on Renewable Chemical Processes

Chemical engineering researchers Wei Fan, Paul Dauenhauer and colleagues at the University of Massachusetts Amherst report this week that they’ve discovered a new chemical process to make p-xylene, an important ingredient of common plastics, at 90 percent yield from lignocellulosic biomass, the highest yield achieved to date. Details are in the current issue of Green Chemistry.

Physicists Predict Unusual Properties of Nanoparticle Crystal Growth

Growing thin films out of nanoparticles in ordered, crystalline sheets, to make anything from microelectronic components to solar cells, would be a boon for materials researchers, but the physics is tricky because particles of that size don’t form crystals the way individual atoms do.

NIST Researchers Create UV Metamaterial Lens from Alternating Silver Nanolayers and Titanium Dioxide

For the first time, scientists working at the National Institute of Standards and Technology (NIST) have demonstrated a new type of lens that bends and focuses ultraviolet (UV) light in such an unusual way that it can create ghostly, 3D images of objects that float in free space.

Solar-Powered Nano Filter Removes Harmful Carcinogens and Antibiotics from Water Sources

Researchers at University of Cincinnati have developed and tested a solar-powered nano filter that is able to remove harmful carcinogens and antibiotics from water sources – lakes and rivers – at a significantly higher rate than the currently used filtering technology made of activated carbon. They report their results today at the 113th General Meeting of the American Society for Microbiology.
