Workshops

WK1

Tues
May 3
all day

 

Nanoscale Bio-hybrid Materials
Tijana Rajh, Chemistry Division, Argonne National Laboratory

Future breakthroughs in nanoscience and nanotechnology are anticipated to be founded on the creation of new classes of functional materials that incorporate tuned nanoscale architectures and biologically active molecules, offering opportunities in diverse applications ranging from quantum computation, energy, and advanced medical therapies. The workshop focuses on exploring energy and charge transfer in nontraditional electronic materials ranging from supramolecular to biomolecular assemblies (such as DNA and proteins). Special focus will be on hybrid materials that combine robustness and reactivity of nanocrystalline materials with molecular recognition and selectivity of biomolecules, allowing for controlled reactivity and special positioning of hybrid materials with biological specificity.

 

WK2

Tues

all day

 

Advanced Nanopatterning
Leo Ocola and Derrick Mancini, Advanced Photon Source

This workshop will be a forum for current CNM users who are involved in nanofabrication projects and researchers in the scientific community to share their experiences in nanofabrication at Argonne and institutions nearby. Presentations will highlight the use of the Raith 150 ebeam tool at Argonne, nanoimprint, nanoembossing, and/or other novel nanopatterning techniques (top-down or bottom-up).

 

WK3

Tues
May 3
all day

Scientific Applications of the Hard X-ray Nanoprobe
Jörg Maser, Advanced Photon Source; Brian Stephenson, Materials Science Division, Argonne National Laboratory; and Paul Evans, University of Wisconsin-Madison

A hard x-ray nanoprobe beamline is being constructed at sector 26 of the Advanced Photon Source. It is designed to characterize nanoscale systems and devices at a spatial resolution of 30 nm, using x-ray fluorescence spectroscopy, x-ray diffraction, and transmission imaging. This workshop is aimed at exploring future scientific applications of the instrument, such as the study of biological and bio-inorganic composites, complex oxides, and magnetic materials.

Scattering from Liquid Surfaces and Interfaces
Binhua Lin, CARS, The University of Chicago, and Ivan Kuzmenko, Advanced Photon Source

Understanding of interfacial properties and thermodynamics is fundamental in many research areas, including biological structure-function, molecular recognition, interfacial self-assembly, molecular engineering of soft interfaces, and molecular transport across interfaces. The application of surface-sensitive synchrotron x-ray scattering techniques has led to a major advance in the investigation of phenomena at liquid surfaces and interfaces. This workshop will highlight recent work on liquid surfaces and interfaces, including lipid-protein interactions at the air/water interface, organic/inorganic Langmuir monolayer systems, electrified liquid/liquid interfaces, liquid metal-X interfaces, surfaces of polymer liquids, and pure liquid surfaces/interfaces.

Metals and Metalloids in Cell Biology
Gayle Woloschak, Northwestern University, and Dina Mandoli, University of Washington

Recent studies in proteomics have lead to the identification of the "metaloproteome," the identification and study of metal-binding proteins. As this area of biology is exploding with new information, the application of the new data to intracellular studies is still lagging behind. This workshop will explore applications of x-ray microscopy to detection of metals/metal-binding proteins in cells. A special emphasis will be placed on new applications and novel approaches to using x-ray microscopy for studies in mammalian, bacterial, plant, and environmental systems.

 

WK7

Thurs

Deep X-ray Lithography and LIGA
Carlo Segre, Illinois Institute of Technology; Derrick Mancini, Advanced Photon Source; and Jeremy Kropf, Chemical Engineering Division, Argonne National Laboratory

This workshop will explore the opportunities and challenges for research and industrial application of deep x-ray lithography and LIGA using the tunable hard x-ray source available at the Materials Research Collaborative Access Team bending magnet beamline (APS, MRCAT, Sector 10). Invited speakers will present their research on creating high-aspect-ratio structures using deep x-ray lithography and implementing LIGA technology for manufacturing. The organizers will also invite discussion of the beamline and laboratory capabilities in order to create a roadmap for future development.

Applications of Grazing-Incidence Small-Angle X-ray Scattering
Jin Wang, Advanced Photon Source, and Randall Winans, Chemistry Division, Argonne National Laboratory

As an increasingly important structural-characterization technique, grazing-incidence small-angle scattering (GISAXS) finds vast application in nanostructures and nanocomposites at surfaces and interfaces. Most significantly, as a complementary method to conventional surface-sensitive tools such as scanning probe microscopy and electron microscopy, GISAXS can be used in situ and in real time to monitor the formation of a nanostructure or nanocomposite. This capability makes it especially suitable for studying the kinetics of nanoassembly processes. This workshop will focus on the applications of GISAXS and the current technical capability at the APS to support general users in this area.

 

WK9 Fri

Generation and Use of Short X-ray Pulses at APS
Dennis Mills and Kwang-Je Kim, Advanced Photon Source

The primary purpose of this workshop is to present preliminary results of accelerator and optics calculations leading to the production of short (~1 ps) x-ray pulses from the Advanced Photon Source storage ring and to summarize the science driving this project.
