Potentially very-useful "polymer opals" change color when stretched

Some of the most vividly colored materials in nature, including things like butterfly wings, don’t obtain their color from pigment. Instead, their internal structure reflects light at a given wavelength, producing a specific color. Opals are another example of something that utilizes this effect. In collaboration with Germany’s Fraunhofer Institute for Structural Durability and System Reliability, scientists from the University of Cambridge have now copied the colorful nanostructure of the opal. The result is a flexible, colorful material that won’t fade over time, that changes color when stretched, and that could have many applications. Read More

Planned Vikings Stadium will have world's largest transparent roof

The Minnesota Vikings American football team has announced the final design for a new stadium to built in the Minneapolis city center that will feature the world’s largest transparent roof. This feat will be achieved using state-of-the-art polymer instead of glass to resist the extremes of Minnesota’s climate, while providing views of the city skyline and a sense of openness for fans and players alike.

Swarms of tiny "microgrippers" used to perform biopsies

When procuring tissue samples for medical diagnosis, doctors have been confined to bulky and invasive forceps. But with recent successful experiments in pigs, we may see doctors switching from the single forceps to hordes of a thousand "microgrippers." These metal discs, each only 300 micrometers in size, are designed to snip bits of tissue when introduced en masse into the body and then be easily retrieved by a doctor. Their small size, added to the fact that they need no batteries, tethers or wires, belies their complexity and autonomy in function, which could allow the microgrippers to provide diagnoses earlier, more easily, and with less trauma.

Sulfur-based polymers open door to a new class of battery

Whether sulfur is a by-product or a waste product of oil refinement and coal combustion depends on how you slice it. Certainly, some of that sulfur can be put to use producing sulfuric acid, fertilizer and other chemicals, but much of it is accumulating into stockpiles that are expensive to maintain (due to the need to neutralize acidic run-off). Researchers at the University of Arizona think more of that sulfur could be put to use thanks to a new chemical process that uses sulfur to make plastics that may one day be used to make a new generation of lighter, more efficient lithium-sulfur batteries.

New transparent, flat, flexible image sensor has potential for gesture control displays

A research team from the Johannes Kepler University Linz in Austria has developed an image capturing device using a single sheet of polymer that is flat, flexible and transparent. The researchers say the new image sensor could eventually find its way into devices like digital cameras and medical scanners, and that it may help to usher in a new generation of gesture-controlled smartphones, tablets and TVs.

Scientists develop "eco-friendly" antibacterial material

Because they’re known for being effective killers of bacteria, silver nanoparticles have been finding their way into a wide variety of antimicrobial materials. There are concerns, however, regarding the consequences of those nanoparticles being shed by the material and entering the environment. In particular, there are worries that through continuous low-level exposure to the nanoparticles, bacteria could develop a resistance to them. Now, researchers from Sweden’s KTH Royal Institute of Technology have announced the development of a new type of antibacterial material, that they claim won’t cause such problems. Read More
