04.04 Advances in Small Angle ScatteringSession Organizer(s): Ken Littrell and Soenke Seifert
Session Focus: Small-angle scattering is a measurement technique that is uniquely well-suited to probing structural information on the length scales from nanometers to a micron. The usefulness and range of applicability of this technique is growing rapidly due to improvements in instrumentation, sample environment, and analysis methods. Examples of these recent developments include focusing of neutron beams and microfocusing of X-ray beams, developments in neutron polarization analysis and control techniques for small-angle scattering, Larmor-labeling for high-flux real-space neutron spin-echo correlation length measurements (SESAME), combined small-angle scattering and dynamics by XPCS and SANS+MIEZE and imaging using small-angle scattering as a contrast variable. This session is devoted to exploring these and other recent advances to the technique of small angle scattering and the new types of scientific exploration that are made possible through their use.
05.01 Cool Structures (Small Molecule)Session Organizer(s): Peter Müller, MIT, Boston, MA (firstname.lastname@example.org).
Session Focus: Papers are invited pertaining to "Cool Structures".

In fact, anything that you may consider to be cool, neat or otherwise interesting crystallographically can be a "Cool Structure".
06.01 Supramolecular ChemistryAcknowledgement is made to the Natural Sciences & Engineering Research Council of Canada (NSERC), for partial support of this symposium.
Session Organizer(s): Christer Aakeröy (email@example.com) and Gary Enright (Gary.Enright@nrc-cnrc.gc.ca)
Session Focus: Supramolecular chemistry remains focused on "the chemistry beyond the molecule", but it is attracting attention from an ever-widening spectrum of scientists. In practice, supramolecular chemistry can be many things; synthesis, theory of intermolecular interactions, molecular recognition and binding in solution, but increasingly, the solid state is playing a key role in promoting an understanding of the balance between intermolecular interactions, and the connections between molecular structure and bulk properties of solids. This symposium will showcase some important trends and discoveries (both fundamental and applied) at the forefront of supramolecular chemistry.

06.02 Shape-Memory Materials (Neutron, Materials)Session Organizer(s): Steve Shapiro, Brookhaven National Laboratory
Session Focus: A fundamental property of Shape Memory Materials (SMM) is the structural phase transition from the high temperature parent phase to the low temperature martensite phase. This session will explore the driving mechanism of the transformation and the multiscale properties of the materials ranging from the small-scale atomic arrangements to the larger scale domain distributions and their relationships to the engineering applications of SMM. The modification of the transformation due to external perturbation such as stress, magnetic field, etc. will also be discussed

06.06 Would You Publish This? (Small Molecule, Service, General)Acknowledgement is made to Oxford Diffraction for partial support of this symposium
Session Organizer(s): Carla Slebodnick (firstname.lastname@example.org)
Session Focus: Small molecule and service crystallographers are often faced with crystal structures of moderate or poor quality and limited scientific interest. This session aims to stimulate friendly discussion addressing the following questions: (1) When is a structure too poor to publish? (2) How much does (should) scientific impact affect this decision? (3) What are some recommended procedures for publishing poor quality structures? (4) How do members of the service community reach compromises (or not) with clients regarding publication of such structures?
Five-ten minutes will be allotted for oral presentations. Oral presentations will not count toward your one allowed conference paper. Presentation content should be limited to the scientific importance of the structure, the structure flaws, and structure fate (tentative or final). Ample discussion time will be available for audience feedback. Submissions are encouraged from both 'junior' crystallographers who are looking for feedback on specific structures and 'senior' crystallographers who can provide useful insight.
06.07 Superconducting Materials (Materials, Neutron)Session Organizer(s): John Mitchell, Argonne National Laboratory
Session Focus: Superconductivity remains an extremely active research focus in condensed matter physics, materials design and discovery, and structure-property studies. The discovery of new superconductors such as the pnictides and pnictide oxides and layered cobalt oxides demonstrates that there remain many opportunities in this field, with chemical crystallography at the vanguard. Indeed, understanding the chemistry and structure of such new materials is often the first step toward a physical picture of their behaviors. This session will focus on exploring the crystallography and structural chemistry of superconducting materials both novel and well-known. Contributions from all areas of materials discovery and structure-property studies of existing or novel superconducting materials are encouraged.

Session Organizer(s): Ovidiu Garlea, Neutron Scattering Science Division, Oak Ridge National Laboratory (firstname.lastname@example.org)
Session Focus: Magnetic structural studies and the interplay among spin, orbital and lattice degrees of freedom. Phase transitions and cooperative phenomena in magnetic systems are governed by the interplay between the spin, lattice, charge and orbital degrees of freedom. Geometric frustration and randomness can bring richness to cooperative behavior and give rise to a variety of exotic phases. Probing the underlying physics of such systems presents a substantial challenge both experimentally and theoretically. This session will feature presentations on recent research where neutron and X-ray scattering techniques were used to probe the structure and magnetic phase diagrams of several specific correlated-electron systems.

06.19 Membrane and Associated ProteinsSession Organizer(s): Thomas Weiss (mailto:firstname.lastname@example.org)
Session Focus: Membrane proteins and their interaction with the lipid matrix play an important role in a variety of biological processes. Beyond this biological relevance of membrane-protein interactions, it recently has become apparent that the membrane can also serve as "tool" in the laboratory to help to crystallize membrane proteins or as a delivery vehicle for drugs and genes into cells. The focus of this session is the biological and model membrane and its interaction and association with membrane proteins or DNA. Contributions on membrane based methods for protein crystallization and drug delivery are also encouraged.

06.21 Educational Outreach in CrystallographySession Organizer(s): Cora Lind, Univ. of Toledo, Ohio (email@example.com), Joseph Ng
Session Focus: Crystallography is becoming a more widely available and used tool in many research fields, however, the formal teaching of crystallography has not kept up with these rapid developments. Over the past few years, significant efforts have been made to develop crystallographic teaching methods that are appropriate for introducing material at the K-12 and undergraduate level. This session will share such teaching approaches, and demonstrate their feasibility through contributions by high school students and teachers who have been exposed to such teaching.
