Researchers from Juelich and Aachen investigate phase change materials Optical data carriers such as DVDs, Blu-rays and CD-RWs store data in layers of so-called "phase change materials". In the future, these materials will enable the development of fast, non-volatile and energy-saving main memories. A prerequisite for this is a low thermal conductivity. Phase change materials display a surprisingly low thermal conductivity even in the crystalline state. This is described by an international...

New insights into why and how nanowires take the form they do will have profound implications for the development of future electronic components. PhD student Peter Krogstrup from the Nano-Science Center at the University of Copenhagen is behind the sensational new theoretical model, which is developed in collaboration with researchers from CINAM-CNRS in Marseille. One of the most important components in future electronic devices will likely be based on nanocrystals, which are smaller than...

LOS ANGELES, Feb. 4, 2011 /PRNewswire/ -- While many travelers are digging themselves out of record-setting winter weather, Crystal Cruises is offering six warm-weather getaways through the Panama Canal in 2011, the first departing as soon as February 23. With four of the tropical voyages leaving from easy-to-get-to U.S. cities such as Miami, San Francisco, and Los Angeles, and several recently announced savings promotions, the winter and fall sailings offer a stress-free, luxury escape to...

Researchers in Britain and Denmark have unveiled an "Ëœinvisibility cloak' that uses a common crystalline material known as calcite, which works by sending its two "polarizations" of light in different directions. Cloaking involves guiding light waves in such a way that waves from a hidden object do not reach the eye.  By using calcite, the researchers created an "Ëœinvisibility cloak' that hid a small (inch-size), three-dimensional object.  However, the size of...

The change-over to lead-free products is in full progress. The problem is however that the environmentally friendly alternatives have to be as effi cient as the lead-containing variants. One example is the injection system of diesel engines. Lead-free functional materials can be found faster by means of computer simulation methods. Technical progress in the automobile industry is unbroken. But, the sector has still some hard nuts to crack: "Lead-free materials" is one of the challenges...

Researchers have developed a method for curbing the growth of crystals that form cystine kidney stones. Their findings, which appear in the latest issue of the journal Science, may offer a pathway to a new method for the prevention of kidney stones. The study was conducted by researchers at New York University's Department of Chemistry and its Molecular Design Institute, NYU School of Medicine, and the Medical College of Wisconsin. Kidney stones comprised of L-cystine affect at least 20,000...

Chemists at Vanderbilt University have created a new class of liquid crystals with unique electrical properties that could improve the performance of digital displays used on everything from digital watches to flat panel televisions. The achievement, which is the result of more than five years of effort, is described by Professor of Chemistry Piotr Kaszynski and graduate student Bryan Ringstrand in a pair of articles published online on Sept. 24 and Sept. 28 in the Journal of Materials...

Because one of the main bottlenecks in determining the structure of protein molecules is producing good isolated single crystals, improved crystallization techniques would be useful in a wide range of genomics and pharmaceutical research. Research reported in The Journal of Chemical Physics uses fluorescence correlation spectroscopy (FCS) to investigate the processes at the surface of a growing crystal. By focusing a laser on the crystal surface and measuring the resulting fluorescence, FCS...

Earth's climate is strongly influenced by the presence of particles of different shapes and origins -- in the form of dust, ice and pollutants -- that find their way into the lowest portion of the atmosphere, the troposphere. There, water adsorbed on the surface of these particles can freeze at higher temperatures than pure water droplets, triggering rain and snow. Researchers at Spain's Centre d'Investigaci³ en Nanocincia i Nanotecnologia (CIN2) have studied the underlying mechanisms of...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
