Mapping the structure of protonated water clusters Water molecules are continuously forming short-lived networks called clusters. These can in turn bind positively charged protons, and such clusters can provide active functional groups in proteins. Using infrared spectroscopy, it is possible to determine the bond strengths, geometrical structures and chemical properties of protonated water clusters. In order to measure the spectrum of molecular vibrations in clusters it is, however, necessary...

For their look into the nanoworld, the Jlich researchers used a scanning tunneling microscope. Its thin metal tip scans the specimen surface like the needle of a record player and registers the atomic irregularities and differences of approximately one nanometer (a billionth of a millimeter) with minuscule electric currents. However, even though the tip of the microscope only has the width of an atom, it has not been able so far to take a look inside molecules."In order to increase the...

ABERDEEN, Scotland and ZURICH, Aug. 2 /PRNewswire-FirstCall/ -- In a pioneering research project, for the first time, scientists at IBM (NYSE: IBM) and the University of Aberdeen have collaborated to "see" the structure of a marine compound from the deepest place on the Earth using an atomic force microscope (AFM). The results of the project open up new possibilities in biological research which could lead to the faster development of new medicines in the future. (Logo:...

Scientists at the National Research Council of Canada (NRC) and the University of Ottawa (uOttawa) enjoyed a bird's eye view of a chemical bond as it breaks. The making and breaking of chemical bonds underlie the biochemical processes of life itself. A greater understanding of the quantum processes that lead to chemical reactions may lead to new strategies in the design and control of molecules "” ultimately leading to scientific breakthroughs in health care and diagnostic medicine,...

'Most condensed form of energy storage outside of nuclear energy' The world's biggest Roman candle has got nothing on this. Using super-high pressures similar to those found deep in the Earth or on a giant planet, Washington State University researchers have created a compact, never-before-seen material capable of storing vast amounts of energy. "If you think about it, it is the most condensed form of energy storage outside of nuclear energy," says Choong-Shik Yoo, a WSU chemistry professor...

SLAC's Linac Coherent Light Source probes nitrogen molecules The SLAC linear collider in Menlo Park, California has already made a name for itself as one of the world's largest and most prolific particle accelerator facilities dedicated to high energy particle physics. It is now beginning a new life as a source of x-rays a billion times brighter than any other research x-ray source to date. Early results that reveal how molecules respond to intense radiation from the facility's Linac Coherent...

With controlled stretching of molecules, Cornell researchers have demonstrated that single-molecule devices can serve as powerful new tools for fundamental science experiments. Their work has resulted in detailed tests of long-existing theories on how electrons interact at the nanoscale. The work, led by professor of physics Dan Ralph, is published in the June 10 online edition of the journal Science. First author is J.J. Parks, a former graduate student in Ralph's lab. The scientists studied...

Finding presents a powerful new tool for nanoscale science experiments Cornell University researchers recently stretched individual molecules and watched electrons flow through them, proving that single-molecule devices can be used as powerful new tools for nanoscale science experiments. The finding, reported in the June 11 issue of the journal Science, probes the effects of strong electron interactions that can be important when shrinking electronics to their ultimate small size...

In a paper in Nature Chemistry, Vivek Shenoy and colleagues pinpointed noncarbon atoms that create defects when graphene is produced through a technique called graphene-oxide reduction. The researchers also propose how to make that technique more efficient by precisely applying hydrogen "“ rather than heat "“ to remove the impurities. Graphene, a carbon sheet that is one-atom thick, may be at the center of the next revolution in material science. These ultrathin sheets hold great...

Scrutinizing a single molecule for more than a few milliseconds used to require effectively "stapling" it down, inhibiting its normal behavior. Now, using a technique recently developed in their lab, Stanford chemists have for the first time confined a protein (one involved in photosynthesis), observed its behavior for more than a second and learned things about it that could influence solar energy technology and biofuels. For the first time, researchers have been able to confine and study an...


Word of the Day
cruet
  • A vial or small glass bottle, especially one for holding vinegar, oil, etc.; a caster for liquids.
This word is Middle English in origin, and ultimately comes from the Old French, diminutive of 'crue,' flask.
