One step to solar-cell efficiency: Researchers' chemical process may improve manufacturing
Rice University scientists have created a one-step process for producing highly efficient materials that let the maximum amount of sunlight reach a solar cell.
A unique glance into the Sun's atmosphere
Three months after the flight of the balloon-borne solar observatory Sunrise, scientists from the Max Planck Institute for Solar System Research (MPS) in Germany now present unique insights into the central ...
Light bursts out of a flying mirror
(Phys.org) —An international team of researchers succeeds in generating flashes of extreme ultraviolet radiation via the reflection from a mirror that moves close to the speed of light.
Why NASA observes the Sun in different wavelengths
(Phys.org)—Taking a photo of the sun with a standard camera will provide a familiar image: a yellowish, featureless disk, perhaps colored a bit more red when near the horizon since the light must travel ...
Nanophotonics technology enables a new kind of optical spectrometer
(Phys.org)—By bringing nanophotonics technology to traditional optical spectroscopy, a new kind of optical spectrometer with functions of sensing and spectral measurement has been recently demonstrated ...
Hubble tells a tale of galactic collisions
(Phys.org) —When we look into the distant cosmos, the great majority of the objects we see are galaxies: immense gatherings of stars, planets, gas, dust, and dark matter, showing up in all kind of shapes. ...
Pink diamond 'behaviour' solved but colour still a mystery
UWA scientists have explained the photochromic behaviour of the pink diamond in an attempt to uncover why they possess their pink colouration.
First 'bone' of the Milky Way identified
(Phys.org)—Our Milky Way is a spiral galaxy—a pinwheel-shaped collection of stars, gas and dust. It has a central bar and two major spiral arms that wrap around its disk. Since we view the Milky Way from ...
Researchers build fully mechanical phonon laser
Research on cilia heats up: Implications for hearing, vision loss and kidney disease
Experiments at Johns Hopkins have unearthed clues about which protein signaling molecules are allowed into hollow, hair-like "antennae," called cilia, that alert cells to critical changes in their environments.
Scientists engineer novel DNA barcode
Much like the checkout clerk uses a machine that scans the barcodes on packages to identify what customers bought at the store, scientists use powerful microscopes and their own kinds of barcodes to help ...
Structure of certain types of beetle shells could inspire brighter, whiter coatings and materials
The physical properties of the ultra-white scales on certain species of beetle could be used to make whiter paper, plastics and paints, while using far less material than is used in current manufacturing ...
'Nanocamera' takes pictures at distances smaller than light's own wavelength
Researchers at the University of Illinois at Urbana-Champaign have demonstrated that an array of novel gold, pillar-bowtie nanoantennas (pBNAs) can be used like traditional photographic film to record light ...
Killing cancer cells with acid reflux
A University of Central Florida chemist has come up with a unique way to kill certain cancer cells – give them acid reflux.
