UMD physicists discover 'smoke rings' made of laser light

Orbital angular momentum (OAM) vortices (pink ringlike objects) are laser light structures that rotate around a central beam, much like water circles around a drain. Physicists and engineers have studied this type of laser vortex since the 1990s as a tool to help improve microscopy and telecommunications.Most basic physics textbooks describe laser light in fairly simple terms: a beam travels directly from one point to another and, unless it strikes a mirror or other reflective surface,...

For first time, carbon nanotube transistors outperform silicon

The UW-Madison engineers use a solution process to deposit aligned arrays of carbon nanotubes onto 1 inch by 1 inch substrates. The researchers used their scalable and rapid deposition process to coat the entire surface of this substrate with aligned carbon nanotubes in less than 5 minutes. The team's breakthrough could pave the way for carbon nanotube transistors to replace silicon transistors, and is particularly promising for wireless communications technologies. - <a target="_blank"href="http://news.wisc.edu/for-first-time-carbon-nanotube-transistors-outperform-silicon/#sthash.Ve5BgAKs.dpuf">See more</a>.For decades, scientists have tried to harness the unique properties of carbon nanotubes to create high-performance electronics that are faster or consume less power -- resulting in longer battery life,...

Water helps assembly of biofibers that could capture sunlight

A new study from Argonne National Laboratory has shown water can serve a previously undiscovered role to help micelles coalesce to spontaneously form long fibers. The study could help scientists to understand how light-harvesting molecules are incorporated into the micelle fiber as it assembles, which would be a key step to understanding some forms of artificial photosynthesis.When it comes to water, some materials have a split personality - and some of these materials could hold the key to new ways of harnessing solar energy.

Location matters in the self-assembly of nanoclusters

Capture zones (CZs) constructed to surround 2-D islands (black rectangles) formed by deposition on a perfect surface. CZ boundaries are indicated by thin lines. The CZs completely cover or tessellate the surface with one CZ per island. A small CZ formed directly by nucleation of a new island near the center of a triangle of existing islands is shown in yellow. Another small CZ formed by corralling of the central island is shown in blue. The lower inset shows how nucleation of a new island (at the X) modifies the CZ distribution. The upper inset shows the distribution of scaled CZ areas.Scientists at Iowa State University have developed a new formulation that helps to explain the self-assembly of atoms into nanoclusters and to advance the scientific understanding of related nanotechnologies. Their...
