Tuesday, April 29, 2014: 1:00PM LCLS Building 901, Redtail Hawk Conference Rooms Speaker: Richard Sandberg (Laboratory for Ultrafast Materials and Optical Science, Los Alamos National Laboratory)   Abstract The response of micron-scale inhomogeneities dictates the overall dynamic response of many material systems including failure under strain in structural materials, dynamics of nanoscale magnetic ordering, and…
Mariano Trigo
Mariano Trigo, PULSE, SLAC National Accelerator Laboratory When:  Wednesday, April 9, 2014 at 3:00PM to 4:00 PM Where: B901 Rm 108B – Redtail I will show that broadband, hard x-ray pulses from LCLS can be used to probe the vibrational spectrum (phonon dispersion) of a solid with sub-meV energy resolution over the entire Brillouin zone.…
Hartawan Laksmono
Hartawan Laksmono, PULSE, SLAC National Accelerator Laboratory When:  Friday, March 28, 2013 at 2:00PM to 3:00 PM Where: B901 Rm 108B – Redtail X-ray scattering is a powerful technique to observe structural changes. Small angle X-ray scattering (SAXS) is particularly useful to observe change in nanometer length scale while wide angle X-ray scattering (WAXS) or…

Lecture by: Hasan Demirci March 25, 2014 7:30-8:30 PM SLAC Campus/Kavli Auditorium  Watch Lecture
psss-20140212
Speaker: Victor Kimberg, Max Planck Institute for the Physics of Complex Systems SLAC, Redtail Hawk Conference Room 108A Program Description I will present our resent theoretical results on stimulated x-ray emission processes in diatomic molecules using XFEL sources. We employ advantages of forward scattering geometry allowing for strong amplification of the x-ray emission signal and high-gain…

Please join Apurva Mehta, SSRL for today's Photon Science Seminar, "Why Vascular Stents Sometimes Break." The phenomenon of superelasticity in near-equiatomic NiTi (Nitinol), which originates from a first order martensitic phase transition, is exploited in an increasing number of biomedical devices, most importantly endovascular stents. Deployment of these superelastic stents, especially in peripheral arteries such…

Recent years have witnessed tremendous progress in our understanding of the ultrafast and ultra-small world thanks to the development of ultrafast optical lasers and the advent of X-ray Free Electron Laser (XFEL). Other approach that utilizes electrons as a probe have demonstrated the potential complementary to the X-ray based techniques. Electron based techniques enjoy many…

The emergence of bacteria resistant to important classes of antibiotics has become a major clinical problem over the last few years, and now almost all antibacterial compounds in use today have associated examples of resistant bacterial isolates. Resistance to penicillins for example has been known since the late 1940's, not long after these compounds were…
