Research & Technology News
X-ray Facility to Investigate Earth’s Core
GRENOBLE, France, Nov. 15, 2011 — ID24, a new x-ray beamline developed at the European Synchrotron Radiation Facility (ESRF), will explore the last white spot on our globe: the center of Earth. This computer-generated image shows the layers of the Earth: the outer solid crust, the viscous upper and lower mantle, the liquid outer core and the solid inner core. (Credit: ESRF) The device soon could explore matter at temperatures and pressures so extreme they can be produced for only microseconds using powerful pulsed...
Light Converts 2-D Patterns into 3-D Objects
RALEIGH, N.C., Nov. 14, 2011 — Two-dimensional patterns that can self-fold into 3-D objects using only light have generated a breakthrough that could have applications in manufacturing processes or packaging. The technique takes a prestressed plastic sheet — made from the...
Professor Seeks Patent on Possible ITO Replacement
CINCINNATI, Nov. 14, 2011 — A highly transparent and electrically conductive polymer-based film that could replace the expensive and rare indium tin oxide (ITO) may soon earn a US patent. The innovative film has potential uses in energy, including applications in solar and...
Hubble Uncovers Tiny Galaxies Bursting with Star Birth
HEIDELBERG, Germany, Nov. 11, 2011 — The Hubble Space Telescope has uncovered an extraordinary population of tiny young galaxies 9 billion light-years away that are brimming with star formation. The galaxies are churning out stars at such a rate that the number of stars in them will...
Interferometer in the Running for ICON Mission
WASHINGTON, Nov. 11, 2011 — The Michelson Interferometer for Global High-resolution Thermospheric Imaging (MIGHTI) will be considered as an addition to NASA’s proposed Ionospheric Connection Explorer (ICON) mission, which would fly instruments designed to collect data on...
Metamaterials Pave Way for Superlens
ITHACA, N.Y., Nov. 11, 2011 — Casting tiny, oddly shaped metal structures inside plastic molds could give a boost to creating metamaterials for making “superlenses” that can image proteins, viruses and DNA. Metamaterials, which offer new ways to manipulate...
Superblack Material Absorbs Multiwavelengths of Light
GREENBELT, Md., Nov. 11, 2011 — A thin layer of multiwalled carbon nanotubes constitutes a new superblack material that absorbs 99 percent of multiple wavelengths of light — an achievement that promises to open new frontiers in space technology. The nanotubes are positioned...
Laser-Driven Technique Lets Sound Be Seen
MIDDLESEX, England, Nov. 8, 2011 — A laser-driven technique that allows remote, noninvasive and rapid mapping of sound fields has been developed — a solution expected to help high-performance loudspeaker manufacturers overcome the issue of dead spots. Dead spots are caused by...
Efficient, Flexible OLED on Plastic Engineered
TORONTO, Nov. 9, 2011 — An advanced optical thin-film coating that allows organic LEDs on plastic to be as efficient as those made on rigid glass unlocks the potential of OLEDs and leads the way toward flexible, lighter, less expensive and impact-resistant displays. The...
Gravitational Lensing Technique Discerns Distant Quasar
PARIS, Nov. 9, 2011 — A new twist on gravitational lensing has led to a unique view of a quasar surrounding a distant black hole. While black holes themselves are invisible, the forces they unleash cause some of the brightest phenomena in the universe. Quasars...
Skin ‘Sees’ UV Light, Produces Melanin
PROVIDENCE, R.I., Nov. 9, 2011 — A light-sensitive receptor (rhodopsis) previously thought to exist only in the eye has been found in human skin cells, detecting certain wavelengths of ultraviolet light to protect DNA from damage. Skin cells, called malanocyte, send out...
Flexible Microscope Explores Deeply Hidden Cells
WYNNEWOOD, Pa., Nov. 8, 2011 — A tiny, flexible microscope allows surgeons to view living tissue in real time at the cellular level during regular endoscopy procedures, precisely pinpointing what should be immediately removed or treated. The device, dubbed a probe-based...
Microlenses Make Superior Endoscopes
DUISBURG, Germany, Nov. 7, 2011 — A newly developed image sensor transmits perfect 3-D images from inside the human body, thanks to the use of microlenses. The specially designed endoscope enables surgeons to see every detail during an operation, almost as though he were actually...
High-Res Scanner Simulates Automotive Fabrics
DARMSTADT, Germany, Nov. 4, 2011 — Newly developed high-resolution scanners copy objects and fabric samples in just a few minutes, converting them into virtual models with startlingly realistic light effects that will help improve the design of automotive and other products. ...
Spin Lasers in the Fast Lane
BOCHUM, Germany, Nov. 4, 2011 — A new concept for ultrafast semiconductor lasers makes inventive use of the intrinsic angular momentum of electrons, called spin, to break previous speed barriers. The new spin lasers have the potential to achieve modulation frequencies of...
Dream Comes True as Dream Contents Are Measured for First Time
MUNICH, Nov. 3, 2011 — Quantifying brain activity while it is in a dream state has been accomplished for the first time, leading to a deeper understanding of the differences between the brain’s wakeful and sleeping states. The ability to dream is a fascinating...
Multiphoton Endoscope May Equal Fewer Biopsies
ITHACA, N.Y., Nov. 3, 2011 — Taking multiphoton microscopy into a new dimension, a new imaging device under development that can be inserted safely into a patient’s body could minimize the need for unnecessary biopsies. Researchers at Cornell University are...
Photons ‘Photocopied’ for Quantum Computing
GAITHERSBURG, Md., Nov. 3, 2011 — Photon particles from two disparate sources have been rendered indistinguishable without losing their essential quantum properties, suggesting, in principle, that they can connect different types of hardware devices into a single quantum information...
NASA Funds ‘Tractor Beam’ Study
GREENBELT, Md., Nov. 2, 2011 — Though a mainstay in science fiction, tractor beams may no longer be limited to the likes of our imaginations. Thanks to recent funding awarded to NASA’s Goddard Space Flight Center, three experimental methods for corralling particles and...
New EUV Microscope to Lead to Next-Gen Semiconductors
BERKELEY, Calif., Nov. 2, 2011 — Delving into the extreme ultraviolet wavelengths further than ever, a novel microscope is set to provide leaps forward in photolithography technology. The device, dubbed SHARP (for “Semiconductor High-NA Actinic Reticle Review Project”),...
Zinc Oxide Microwires Boost LED Performance
ATLANTA, Nov. 2, 2011 — Through the use of zinc oxide microwires, the efficiency at which gallium nitride LEDs convert electricity to ultraviolet light has improved significantly. The LEDs are believed to be the first whose performance has been enhanced by the creation of...
“Optical switch” could make quantum computers more stable
CAMBRIDGE, Mass. – An optical switch that allows one photon to control the quantum state of another could yield a quantum computer that offers stability and control. Quantum particles have an odd property that enables them to be in “superposition”;...
Designer surfaces rewrite laws of refraction and reflection
CAMBRIDGE, Mass. – A new technique called phase discontinuity helps light break the age-old laws of reflection and refraction – and could lead to the development of flat lenses that can focus images with no aberrations. For centuries, it has been recognized that...
Gas detector lights up around CO
2
KYOTO, Japan – An inexpensive new material can quickly and accurately detect carbon dioxide (CO2) under a variety of circumstances, enabling the development of easy-to-use CO2 monitors. Methods to detect whether specific gases are present in the air already...
Holographic lithography boosts plasmonic nanogap array production
HOBOKEN, N.J. – A technique based on methods from holographic lithography has been developed to demonstrate a new approach for scaling up the fabrication of plasmonic nanogap arrays while simultaneously reducing costs and infrastructure. A team led by Dr. Stefan...
