"486th Brookhaven Lecture: 'The Hard X-ray Nanoprobe at NSLS-II: A Big Microscope to Tackle Challenges at the Nanoscale'"
Presented by Yong Chu, Photon Sciences Directorate at Brookhaven Lab
Wednesday, April 17, 2013, 4 pm
Berkner Hall Auditorium
Hosted by: Allen Orville
During the 486th Brookhaven Lecture, Yong Chu of the Photon Sciences Directorate will illustrate unique challenges and innovative approaches for x-ray microscopy at the nanoscale—measured in billionths of a meter. He will also discuss measurement capabilities for the first science experiments at NSLS-II.

"485th Brookhaven Lecture: The Plasma Window"
Presented by Ady Hershcovitch, Collider-Accelerator Department
Wednesday, March 20, 2013, 4 pm
Berkner Hall Auditorium
Hosted by: Allen Orville
Space…the final frontier. Think back to a Star Trek or Star Wars scene taking place in a space station. Remember ships taking off through large bay doors directly into the vast, empty void of space while people stood on the decks breathing freely without scuba tanks or air supplies on their backs? Sure that was science fiction, but the technology that could separate the empty space outside from the air inside without a sheet of glass or metal is, in fact, real. This technologyâ€""called a plasma window"â€"was developed at Brookhaven Lab and is being used at scientific research facilities around the world. The plasma window has made a difficult but ultra-powerful welding technique more versatile too. On Wednesday, March 20, join Ady Hershcovitch of the Collider-Accelerator Department, for the 485th Brookhaven Lecture, titled "The Plasma Window." All are invited to attend this free talk, which is open to the public and will be held in Berkner Hall at 4 p.m. Refreshments will be offered before and after the lecture. Visitors to the Lab age 16 and older must carry a photo ID while on site. To join Hershcovitch for dinner at a restaurant off site after the talk, contact Sandy Asselta (Ext. 4550).

"483rd Brookhaven Lecture: Coherent X-ray Scattering: Dynamics in Crowded Colloids and Other Stories"
Presented by Andrei Fluerasu, Photon Sciences Directorate at Brookhaven Lab
Wednesday, January 16, 2013, 4 pm
Berkner Hall Auditorium
Hosted by: Allen Orville
Over the last two decades, X-ray Photon Correlation Spectroscopy (XPCS) has become an increasingly important technique in the study of dynamical phenomena in materials. Its applications range from the study of atomic diffusion in disordered metallic system to that of micron-scale fluctuations at polymer surfaces. Achieving a profound understanding of the dynamical properties of materials is arguably one of the most important elements that will enable a transition from a science based on observation to a science based on control - designing materials with specific "tailored" properties, drawing inspiration from biological systems to design novel materials with specific new or improved functionalities, developing materials that will address our society's grand energy challenges. As a consequence, the Coherent Hard X-ray beamline at the NSLS-II light source, one of the first six "project beamlines" to be built with the storage ring, will be dedicated to XPCS and the study of dynamics of materials using intense coherent beams. Here I will describe some of our recent results and possible future applications of XPCS aiming at a better understanding of the dynamics in complex soft materials. In particular I will focus on the dynamics of dense -"crowded"- colloidal suspensions and the dynamics of colloids under flow. Before finalizing, I will show preliminary results demonstrating a path towards measuring complex dynamics in biological systems and biological hybrid materials.

"482nd Brookhaven Lecture: Diamond, An X-ray's Best Friend"
Presented by John Smedley, Instrumentation Division
Wednesday, December 19, 2012, 4 pm
Berkner Hall Auditorium
Hosted by: Allen Orville
John Smedley of the Instrumentation Division will give the 482nd Brookhaven Lecture, titled, "Diamond, An X-ray's Best Friend," on Wednesday, December 19, at 4 p.m. in Berkner Hall. More information about this talk is available in the Monday Memo of December 17: http://1.usa.gov/UMOjsd. To join Smedley for dinner at a restaurant off-site after the talk, contact Donna Grabowski (grabowsk@bnl.gov, Ext. 2720). About the Speaker Smedley earned a Ph.D. in accelerator physics from Stony Brook University in 2001 and a bachelor’s degree in physics and mathematics from Johns Hopkins University in 1994. A member of Brookhaven Lab’s Instrumentation Division, Smedley first arrived at the Lab in 1993 as a summer student. He officially joined the Brookhaven as an assistant physicist in 2004, and was promoted to the title associate physicist in 2006 and then physicist in 2009.
