New nanoscale imaging method finds application in plasmonics

more »

Researchers from the National Institute of Standards and Technology (NIST) and the University of Maryland have shown how to make nanoscale measurements of critical properties of plasmonic nanomaterials—the specially engineered nanostructures that modify the interaction of light and matter for a variety of applications, including sensors, cloaking (invisibility), photovoltaics and therapeutics.

Large wave-vector phonon modes in silicon nanomembranes

more »

(Phys.org) —Modified large wave-vector phonons in semiconductor membranes via hard X-ray thermal diffuse scattering (TDS) were observed that provide new insight into the fundamental thermal and electronic properties of nanomaterials. The observation of X-ray TDS from suspended silicon membranes with thicknesses below 10 nm vastly expands the range of materials for which these vibrational modes can be studied. Understanding phonon confinement in nanostructures will enable control of thermal, optical, and electrical transport properties.

Seeing photosynthesis from space: NASA scientists use satellites to measure plant health

more »

NASA scientists have established a new way to use satellites to measure what's occurring inside plants at a cellular level. Plants grow and thrive through photosynthesis, a process that converts sunlight into energy. During photosynthesis, plants emit what is called fluorescence -- light invisible to the naked eye but detectable by satellites orbiting hundreds of miles above Earth. NASA scientists have now established a method to turn this satellite data into global maps of the subtle phenomenon in more detail than ever before.

Artificial organelles transform free radicals into water and oxygen

more »

Researchers at the University of Basel have successfully developed artificial organelles that are able to support the reduction of toxic oxygen compounds. This opens up new ways in the development of novel drugs that can influence pathological states directly inside the cell. The results have been published in the journal Nano Letters.

Solar system's youth gives clues to planet search

more »

Comets and meteorites contain clues to our solar system's earliest days. But some of the findings are puzzle pieces that don't seem to fit well together. A new set of theoretical models from Carnegie's Alan Boss shows how an outburst event in the Sun's formative years could explain some of this disparate evidence. His work could have implications for the hunt for habitable planets outside of our solar system. It is published by The Astrophysical Journal.

Starburst to star bust: Astronomers ID suspect behind dearth of high-mass galaxies

more »

A new study published in the journal Nature shows how vigorous star formation can turn the tables on a starburst galaxy by forcing hydrogen and other gases high into the surrounding galactic halo, leaving little fuel for the next generation of stars.

Space station research exposing the salty truth of supercritical water transitions

more »

There is a moment when everything changes. Something familiar crosses a boundary and suddenly behaves in new ways. Take water for example. In middle school science class, you probably learned about saturation points when adding salt to a liquid. Or you discovered the importance of phase changes when going from boiling to steam or from freezing to ice. That moment of change is now being studied at a new level in space.

Curiosity makes its longest one-day drive on Mars

more »

NASA's Mars rover Curiosity drove twice as far on July 21 as on any other day of the mission so far: 109.7 yards (100.3 meters). The length of the drive took advantage of starting the 340th Martian day, or sol, of the mission from a location with an unusually good view for rover engineers to plan a safe path. In weeks to come, the rover team plans to begin using "autonav" capability for the rover to autonomously navigate a path for itself, which could make such long drives more frequent.

New NIST nanoscale indenter takes novel approach to measuring surface properties

more »

Researchers from the National Institute of Standards and Technology (NIST) and the University of North Carolina have demonstrated a new design for an instrument, a "instrumented nanoscale indenter," that makes sensitive measurements of the mechanical properties of thin films—ranging from auto body coatings to microelectronic devices—and biomaterials. The NIST instrument uses a unique technique for precisely measuring the depth of the indentation in a test surface with no contact of the surface other than the probe tip itself.
