National Synchrotron Light Source at Brookhaven

The NEXAFS experiments were carried out on the U7A NIST/Dow Materials Soft X-ray Materials Characterization Facility at the National Synchrotron Light Source at Brookhaven National Laboratory (NSLS BNL)... 

National Synchrotron Light Source at Brookhaven National Laboratory. With data such as these, structural research efforts are bolstered significantly and, as was mentioned at the beginning of this discussion, knowledge of the atomic positions in space is of immense value in the characterization of a material. 

Thus, synchrotron radiation finds more and more use today, although its availability is restricted to the existing synchrotron sites. Some of the well-known sites are the ALS - Advanced Light Source at Berkeley Lab, APS -Advanced Photon Source at Argonne National Laboratory, NSLS - National Synchrotron Light Source at Brookhaven National Laboratory, SRS -Synchrotron Radiation Source at Daresbury Laboratory, ESRF - European Synchrotron Radiation Facility in Grenoble, and others. ... 

We compared FTIR spectra of the frozen sample to MeOH at ambient conditions. The results are shown in Figure. 15. When pure methanol is loaded to 5 GPa the ensuing temperature induced reaction proceeds without forming bubbles. We have studied each reproducible reaction process and have determined from FTIR experiments conducted at the National Synchrotron Light Source at Brookhaven National Laboratory (Beam Line U2a) that pure MeOH reacts to form water and carbon dioxide. Methanol subjected to 532nm and 1064 ran 100 ps pulses reacts to form supercritical water, carbon dioxide, ethane, and perhaps methane (see Figures 15, 16, and 17). These same products are predicted by the CHEETAH thermo-chemical code if no carbon, in the form of diamond, is produced. 

As a result of the high X-ray flux available at synchrotron X-ray sources such as that at the National Synchrotron Light Source at Brookhaven National Labs, WAXD patterns (and hence degrees of crystallinity) can be determined during the course of crystallization at a specific temperature, or at programmed heating or coohng rates (see SYNCHROTRON RADIATION). Data is typically acquired over...
