Shiny quantum dots brighten future of solar cells
A house window that doubles as a solar panel could be on the horizon, thanks to recent quantum-dot work by Los Alamos National Laboratory researchers in collaboration with scientists from University of Milano-Bicocca, Italy. Their project demonstrates that superior light-emitting properties of quantum dots can be applied in solar energy by helping more efficiently harvest sunlight.

Pioneering findings on the dual role of carbon dioxide in photosynthesis
Scientists at Umea University in Sweden have found that carbon dioxide, in its ionic form bicarbonate, has a regulating function in the splitting of water in photosynthesis. This means that carbon dioxide has an additional role to being reduced to sugar. The pioneering work is published in the latest issue of the scientific journal PNAS.

New self-healing plastics developed
Scratches in the car finish or cracks in polymer material: self-healing materials can repair themselves by restoring their initial molecular structure after the damage. Scientists of the Karlsruhe Institute of Technology and Evonik Industries have developed a chemical crosslinking reaction that ensures good short-term healing properties of the material under mild heating. The research results have now been published in the Advanced Materials journal.

Researchers develop ErSb nanostructures with applications in infrared and terahertz ranges
UC Santa Barbara have created a compound semiconductor of nearly perfect quality with embedded nanostructures containing ordered lines of atoms that can manipulate light energy in the mid-infrared range. More efficient solar cells, less risky and higher resolution biological imaging, and the ability to transmit massive amounts of data at higher speeds are only a few applications that this unique semiconductor will be able to support.

Virus structure inspires novel understanding of onion-like carbon nanoparticles
Symmetry is ubiquitous in the natural world. It occurs in gemstones and snowflakes and even in biology, an area typically associated with complexity and diversity. There are striking examples: the shapes of virus particles, such as those causing the common cold, are highly symmetrical and look like tiny footballs.

The motion of the medium matters for self-assembling particles, Penn research shows
Earlier work assumed that the liquid medium in which certain self-assembling particles float could be treated as a placid vacuum, but a University of Pennsylvania team has shown that fluid dynamics play a crucial role in the kind and quality of the structures that can be made in this way.

No compromises: JILA's short, flexible, reusable AFM probe
JILA researchers have engineered a short, flexible, reusable probe for the atomic force microscope that enables state-of-the-art precision and stability in picoscale force measurements. Shorter, softer and more agile than standard and recently enhanced AFM probes, the JILA tips will benefit nanotechnology and studies of folding and stretching in biomolecules such as proteins and DNA.

Tiny step edges, big step for surface science
An interesting effect could help build better solar cells and create better chemical catalysts: If a titanium oxide surface is completely flat, the electrons inside the material can move freely. But if there are tiny step edges on the surface, the electrons can localize, and then, oxygen can attach to the surface.

A new twist makes for better steel, researchers find
In steelmaking, two desirable qualities -- strength and ductility -- tend to be at odds: stronger steel is less ductile, and more ductile steel is not as strong. Engineers at Brown University, three Chinese universities, and the Chinese Academy of Sciences have shown that pre-treating steel cylinders by twisting then can improve strength without sacrificing ductility.

Scalable CVD process for making 2-D molybdenum diselenide

Scientists disagree on responsible research
Responsible research has been put firmly on the political agenda with, for instance, EU's Horizon 2020 program in which all research projects must show how they contribute responsibly to society. New research from the University of Copenhagen reveals that the scientists themselves place great emphasis on behaving responsibly; they just disagree on what social responsibility in science entails. Responsibility is, in other words, a matter of perspective.

The Gordon and Betty Moore Foundation and Society for Science & the Public today announced winners of the Science, Play and Research Kit Competition, a challenge to reimagine the chemistry set for the 21st century. Winners were selected in two categories: prototypes -- projects that are operational and demonstrable -- and ideations -- fleshed out project ideas that have not yet been developed into prototypes, but have a strong potential for development.

Trees go high-tech: Process turns cellulose into energy storage devices
A fundamental chemical discovery should allow tress to soon play a major role in making high-tech energy storage devices. A method has been discovered to turn cellulose -- the most abundant organic polymer on Earth and a key component of trees -- into the building blocks for supercapacitors.

Gold nanorods attach to, kill bladder cancer cells
A University of Colorado Cancer Center study presented today at the American Association for Cancer Research Annual Meeting 2014 demonstrates a novel strategy that accomplishes both: bladder cancer cells overexpress the protein EGFR; gold nanorods can be engineered to attach to EGFR proteins; and then the application of low-intensity laser to the tissue can preferentially heat these gold nanorods, killing the EGFR-rich cancer cells to which they are attached.

Groundbreaking optical device could enhance optical information processing, computers
At St. Paul's Cathedral in London, a section of the dome called the Whispering Gallery makes a whisper audible from the other side of the dome as a result of the way sound waves travel around the curved surface. Researchers at Washington University in St. Louis have used the same phenomenon to build an optical device that may lead to new and more powerful computers that run faster and cooler.

To bridge LEDs' green gap, scientists think small... really small
Nanostructures half the breadth of a DNA strand could improve the efficiency of light emitting diodes, especially in the 'green gap,' simulations at the US Department of Energy's National Energy Research Scientific Computing Center have shown. Nanostructure LEDs made from indium nitride could lead to more natural-looking white lighting while avoiding some of the efficiency loss today's LEDs experience at high power.

Energy breakthrough uses sun to create solar energy materials
Researchers have discovered a way to tap the sun not only as a source of power, but also to directly produce the solar energy materials that make this possible. This breakthrough could make the sun almost a 'one-stop shop' that produces both the materials for solar devices and the eternal energy to power them.
