In a new study performed at the Center for Nanoscale Materials at the U.S. Department of Energy´s (DOE) Argonne National Laboratory, researchers have for the first time seen the self-assembly of nanoparticle chains in situ, that is, in place as it occurs in real-time. The scientists exposed a tiny liquid “cell” or pouch that contained gold nanoparticles covered with a positively charged coating to an intense beam of electrons generated with a transmission electron...

Science Uses X-Rays To Unlock Mystery Of Picasso Paint

Michael Harper for redOrbit.com — Your Universe Online The best way to win any decades-long debate is science, science, and more science. If, for example, you´re able to hire a team of technicians to operate a powerful X-Ray to prove your point, there´s almost no way you´ll lose. Such is the case with a long-standing debate over which type of paint Picasso used in his works. Art scholars have been arguing for many years over the theory that the cubist painter used...

For the first time X-ray scientists have combined high-resolution imaging with 3-D viewing of the surface layer of material using X-ray vision in a way that does not damage the sample. This new technique expands the range of X-ray research possible for biology and many aspects of nanotechnology, particularly nanofilms, photonics, and micro- and nano-electronics. This new technique also reduces "guesswork" by eliminating the need for modeling-dependent structural simulation often used in...

Quantum physics and plant biology seem like two branches of science that could not be more different, but surprisingly they may in fact be intimately tied. Researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory and the Notre Dame Radiation Laboratory at the University of Notre Dame used ultrafast spectroscopy to see what happens at the subatomic level during the very first stage of photosynthesis. "If you think of photosynthesis as a marathon, we're getting a...

While diamonds may be a girl´s best friend, they´re also well-loved by scientists working to enhance the performance of electronic devices. Two new studies performed at the U.S. Department of Energy´s Argonne National Laboratory have revealed a new pathway for materials scientists to use previously unexplored properties of nanocrystalline-diamond thin films. While the properties of diamond thin films are relatively well-understood, the new discovery could dramatically...

For the first time scientists have been able to watch nanoparticles grow from the earliest stages of their formation. Nanoparticles are the foundation of nanotechnology and their performance depends on their structure, composition, and size. Researchers will now be able to develop ways to control conditions under which they are grown. The breakthrough will affect a wide range of applications including solar-cell technology and chemical and biological sensors. The research is published in...

A scientist at the U.S. Department of Energy's (DOE) Argonne National Laboratory has created visible-light catalysis, using silver chloride nanowires decorated with gold nanoparticles, that may decompose organic molecules in polluted water. "Silver nanowires have been extensively studied and used for a variety of applications, including transparent conductive electrodes for solar cells and optoelectronic devices," said nanoscientist Yugang Sun of Argonne's Center for Nanoscale Materials. "By...

A collaboration between the Advanced Photon Source and Center for Nanoscale Materials at U.S. Department of Energy's (DOE) Argonne National Laboratory has "seen" the crystallization of nanoparticles in unprecedented detail. "Nanoscience is a hot issue right now, and people are trying to create self-assembled nanoparticle arrays for data and memory storage," Argonne assistant physicist Zhang Jiang said. "In these devices, the degree of ordering is an important factor." In order to call up a...

Word of the Day
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
