Nature Communications
Researchers transform slow emitters into fast light sources
Phosphors are efficient light emitters but they're not optimal for high-speed communications because they turn on and off slowly. Researchers from Brown and Harvard have now found a way to modulate light from phosphor emitters three orders of magnitude faster using phase-change materials, which could make phosphors useful in a range of new optoelectronic applications.

Umbrella-shaped diamond nanostructures make efficient photon collectors
By tweaking the shape of the diamond nanostructures into the form of tiny umbrellas, researchers from Tokyo Institute of Technology experimentally showed that the fluorescence intensity of their structures was three to five times greater than that of bulk diamond. They report their results in the journal Applied Physics Letters, from AIP Publishing.

Malaria Journal
New approach toward a broad spectrum malaria vaccine
Malaria affects millions of people worldwide. Plasmodium falciparum enolase participates in parasite invasion of host red blood cells and mosquito midgut epithelium. Anti-enolase antibodies interfere with the invasion, inhibiting parasite growth and transmission. A pentapeptide insert of parasite enolase, conserved in all Plasmodia species, but absent from host enolases, shows considerable protection against malaria when displayed on Archaeal gas vesicle nanoparticles. A vaccine based on this motif could confer protection against all malaria parasites.

'Molecular accordion' drives thermoelectric behavior in promising material
Engines, laptops and power plants generate waste heat. Thermoelectric materials, which convert temperature gradients to electricity and vice versa, can recover some of that heat and improve energy efficiency. A team of scientists at the Department of Energy's Oak Ridge National Laboratory explored the fundamental physics of the world's best thermoelectric material -- tin selenide -- using neutron scattering and computer simulations. Their work may aid energy sustainability and design of materials that convert heat into electricity.

Nanotechnology inspires next-generation dental materials
Have a cavity? Ask your dentist about filling it with a mixture of nanoparticles including silica and zirconia. These white fillings resemble teeth better than their metal alternatives and are less likely to come loose or fracture teeth. This is just the beginning argue Brazilian scientists in a review of 'nanodentistry,' published Oct. 19 in Trends in Biotechnology. Next-generation dental materials incorporating nanotechnology aim to help teeth self-heal, rebuild enamel, and protect against bacterial infections.

Nanodiamonds might prevent tooth loss after root canals
Nanodiamonds may help patients that have had the dreaded root canal. UCLA dental researchers have developed a nanodiamond-reinforced version of gutta percha, the compound that is used to fill void spaces in dental root canals to prevent infection that can lead to tooth loss. Tested in patient-extracted teeth, the nanodiamond-embedded polymer was substantially stronger than conventional gutta percha. In addition, the scientists tested gutta percha with nanodiamonds that had been loaded with antibiotics and found that the compound effectively prevented bacterial infection.

What are these nanostars in 2-D superconductor supposed to mean?
Physicists from France and Russia have discovered magnetic disturbances in two-dimensional layered superconductors, resembling small oscillating stars. This experimental observation is the direct confirmation of the famous Yu-Shiba-Rusinov theory which predicted an existence of these quantum bound magnetic states. It was found out that in the 2-D systems the magnetic excitations spread over longer distances as compared to ordinary 3-D superconducting materials. Building and manipulating such protected states is a crucial step towards quantum computers.
