A clever materials science technique that uses a silicon crystal as a sort of nanoscale vise to squeeze another crystal into a more useful shape may launch a new class of electronic devices that remember their last state even after power is turned off.
An international team of scientists has determined the structure of the chlorophyll molecules in green bacteria that are responsible for harvesting light energy. The team's results one day could be used to build artificial photosynthetic systems, such as those that convert solar energy to electrical energy.
Following from technology developed for the NASA Mars Science Laboratory (MSL), inXitu inc., a Silicon Valley based company, has introduced a new benchtop combination X-Ray Diffraction, X-Ray Fluorescence instrument.
The structure and exact water content of calcined gypsum have remained a matter of speculation. Michael F. Bräu and Horst Weiss have now brought this speculation to an end: by using single-crystal structural analyses they were able to solve the structure, generate a structural model, and support it with computer calculations.
With the human genome in hand, biochemists have cataloged the 3-D structures of thousands of proteins isolated from living cells. But one important class of proteins -- those stuck in the cell membranes -- has proven dif...
Leading analytical X-ray company PANalytical
will reinforce its reputation for complete solutions
at this year's ACHEMA conference and exhibition (11 - 15 May 2009; Frankfurt
am Main, Germany).
A team of researchers from Brookhaven, Yeshiva University, and the University of Delaware has demonstrated a new, highly efficient way to synthesize the nanocatalysts based on palladium and gold.
An international team of scientists have discovered a transparent form of
the element sodium (Na).
What has been impossible has now been shown to be possible – an alloy between two incompatible elements. The findings are being published in this week's edition of Proceedings of the National Academy of Science...
A new imaging technique developed by researchers at the University of Illinois overcomes the limit of diffraction and can reveal the atomic structure of a single nanocrystal with a resolution of less than one angstrom (l...
