New Records Set Up with 'Screws of Light'

127057_web.jpg

The research team around Anton Zeilinger has succeeded in breaking two novel records while experimenting with so-called twisted particles of light. In one experiment, the scientists could show that the twist of light itself, i.e. the screw-like structure, is maintained over a free-space propagation of 143 kilometers, which could revolutionize future data transmission.

For the first time, researchers have created light-emitting diodes (LEDs) on lightweight flexible metal foil. Engineers at The Ohio State University are developing the foil based LEDs for portable ultraviolet (UV) lights that soldiers and others can use to purify drinking water and sterilize medical equipment.

Nanoparticle Treatment Adds Antimicrobial Coatings to Leather

Traditional leather manufacturing requires the use of several toxic chemicals, such as halogenated flame retardants or organic antimicrobial solvents, which cause pollution. Now, a team of researchers led by Robert Franz of the Montanuniversität in Leoben, Austria are testing an eco-friendly alternative: silver-titanium nanoparticles.

Shedding Light on the Formation of Nanodroplets in Aqueous Solutions of Polar Organics

Researchers have shed new light on the heterogeneous nature of a polar organic liquid mixed with water. They used laser light as a tool that allowed them to demonstrate the existence of stable nanodroplets of tetrahydrofuran in the bulk of aqueous electrolyte solutions and to develop a new theory that explains the spontaneous generation of heterogeneous nanoparticles in aqueous solutions of polar organic solutes in terms of nanodroplet formation due to “twinkling” hydrogen bonds.

Chemists Create Clusters of Organelles by Mimicking Nature

Nano_clusters_810x610.jpg

Scientists from the University of Basel in Switzerland have succeeded in organizing spherical compartments into clusters mimicking the way natural organelles would create complex structures. They managed to connect the synthetic compartments by creating bridges made of DNA between them. This represents an important step towards the realization of so-called molecular factories. The journal Nano Letters has published their results.

New Technique Reveals Powerful, "Patchy" Approach to Nanoparticle Synthesis

Patches of chain-like molecules placed across nanoscale particles can radically transform the optical, electronic, and magnetic properties of particle-based materials. Now, scientists have used cutting-edge electron tomography techniques—a process of 3D reconstructive imaging—to pinpoint the structure and composition of the polymer nano-patches.

Nano-Decoy Lures Human Influenza a Virus to Its Doom

R.LinhardtFluDendrimer.jpg

To infect its victims, influenza A heads for the lungs, where it latches onto sialic acid on the surface of cells. So researchers created the perfect decoy: A carefully constructed spherical nanoparticle coated in sialic acid lures the influenza A virus to its doom. When misted into the lungs, the nanoparticle traps influenza A, holding it until the virus self-destructs.

Columbia Engineering Professor Yuan Yang has developed a new method to increase the energy density of lithium batteries. He has built a trilayer structure that is stable even in ambient air, which makes the battery both longer lasting and cheaper to manufacture. The work, which may improve the energy density of lithium batteries by 10-30%, is published online today in Nano Letters.
