Not-weak knots bolster carbon fiber
Large flakes of graphene oxide are the essential ingredient in a new recipe for robust carbon fiber created at Rice University. The fiber spun at Rice is unique for the strength of its knots. Most fibers are most likely to snap under tension at the knot, but Rice’s fiber demonstrates what the researchers refer to as “100 percent knot efficiency,” where the fiber is as likely to break anywhere along its length as at the knot.

Imperfect graphene renders ‘electrical highways’
Just an atom thick, 200 times stronger than steel and near-perfect conductor, graphene’s future in electronics is all but certain. But to make this carbon supermaterial useful, it needs to be a semiconductor– a material than can switch between insulating and conducting states, which forms the basis for all electronics today. Combining experiment and theory, Cornell researchers have moved a step closer to making graphene a useful, controllable material. They showed that when grown in stacked layers, graphene produces some specific defects that influence its conductivity.

A sound idea: Innovative lens takes shape as commercial product
On a late night in February 2011, two Princeton University researchers packed a small object into a box and set it out for the morning mail. The engineers had spent four years developing a new type of microscope lens that focuses in response to sound waves. They were sending their innovation to their first customer.

Researchers report first entanglement between light and an optical atomic coherence
Using clouds of ultra-cold atoms and a pair of lasers operating at optical wavelengths, researchers have reached a quantum network milestone: entangling light with an optical atomic coherence composed of interacting atoms in two different states. The development could help pave the way for functional, multi-node quantum networks.

The research, done at the Georgia Institute of Technology, used a new type of optical trap that simultaneously confined both ground-state and highly-excited (Rydberg) atoms of the element ribidium. The large size of the Rydberg atoms – which have a radius of about one micron instead of a usual sub-nanometer size – gives them exaggerated electromagnetic properties and allows them to interact strongly with one another.

Ferroelectric-graphene-based system could lead to improved information processing
Researchers at MIT have proposed a new system that combines ferroelectric materials – the kind often used for data storage – with graphene, a two-dimensional form of carbon known for its exceptional electronic and mechanical properties. The resulting hybrid technology could eventually lead to computer and data-storage chips that pack more components in a given area and are faster and less power-hungry.

Polymer Structures Serve as “Nanoreactors” for Nanocrystals with Uniform Sizes and Shapes

Using star-shaped block co-polymer structures as tiny reaction vessels, researchers have developed an improved technique for producing nanocrystals with consistent sizes, compositions and architectures — including metallic, ferroelectric, magnetic, semiconductor and luminescent nanocrystals. The technique relies on the length of polymer molecules and the ratio of two solvents to control the size and uniformity of colloidal nanocrystals.

Even with Defects, Graphene is Strongest Material in the World

In a new study, published in Science May 31, 2013, Columbia Engineering researchers demonstrate that graphene, even if stitched together from many small crystalline grains, is almost as strong as graphene in its perfect crystalline form. This work resolves a contradiction between theoretical simulations, which predicted that grain boundaries can be strong, and earlier experiments, which indicated that they were much weaker than the perfect lattice. http://engineering.columbia.edu/even-defects-graphene-strongest-material-world

Air Force Research Lab challenges students with real-world warfighter need

The Air Force Research Laboratory (AFRL) has found a winning strategy for solving real world problems facing the warfighter. Each year AFRL poses a clearly defined problem to several universities and service academies, challenging them to compete for a “best solution” based upon certain criteria including system weight, ruggedness, time to employ, effectiveness, cost, and creativity. AFRL wins by collecting the great ideas that emerge from the competitions, while being introduced to some of our country’s finest up-and-coming engineers. University students win by experiencing real-world problem resolution while getting a chance to save the lives of servicemen and women. In addition, they’re able to see how fun it could be to work for AFRL! http://www.wpafb.af.mil/news/story.asp?id=123349385

Shape-shifting Nanoparticles Flip from Sphere to Net in Response to Tumor Signal

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 the 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. http://ucsdnews.ucsd.edu/pressrelease/shape_shifting_nanoparticles_flip_from_sphere_to_net_in_response_to_tu
