11.8.3 Chemical Control of the Properties of Complex Oxides
The world of complex oxides is a fascinating one for chemists and physicists alike. The electronic behavior of oxide materials varies from highly insulating to metallic. Oxides exhibit remarkable versatility, both in terms of their chemical composition and their physical properties. Phenomena found in the oxide family include superconductivity, ferrolectricity, piezoelectricity, ferromagnetism, antiferromagnetism, multiferroicity, colossal magnetoresistance, half-metallicity, and ionic conductivity among others.
This symposium will explore the fascinating behavior of complex oxides through the lens of solid state chemistry. Namely, we will consider how chemical substitution can be used to modify the structures and properties of complex oxides. Extensive research efforts over the past 25 years in areas such as high temperature superconductivity and colossal magnetoresistance have shown how subtle changes in chemistry can lead to dramatic changes in properties. Similar examples can be found in dielectric materials, half-metallic conductors, multiferroics and other oxide based systems.We will explore experimental and theoretical efforts to understand the links between chemical composition and physical properties.

11.8.4 Confined and Biological Water
Water in nanoscopic confinement, at interfaces, and inside biomolecules has unique physical and chemical properties that can differ significantly from those in the bulk phase. Among the many important characteristics of water, confinement and interfaces affect the water structure, its thermodynamics and phase behavior, water dynamics, and proton conductivity. These confinement-induced effects are of fundamental relevance for the physics of water, and have important technological applications exploited, for instance, in the design of new materials, filtration devices, and fuel cells. Moreover, interfacial and confined water is also a key factor in biological systems, affecting the stability, self-assembly and folding, motions, and function of proteins, nucleic acids, and lipid membranes. The objective of this Focus Session is to bring together researchers from different communities (physics, chemistry and biology) interested in the properties of water at the nanoscale, from clusters to interfaces and the hydration of biomolecules. The aim is to present exciting new results on confined and biological water obtained from a diverse range of experimental, computational, and theoretical studies to stimulate discussion and further research.

11.8.5 New Trends in Spectroscopy
Powerful new tools are becoming available for what might be called "massively parallel spectroscopy."New applications of femtosecond frequency combs to spectroscopy and problems in chemical physics are appearing rapidly, following their revolutionary developments in metrology.An assortment of information-rich schemes are being developed to take advantage of these unique light sources.Similarly, revolutionary developments in microwave and mm wave spectroscopy based on chirped pulse phase-coherent methods are enhancing high-resolution spectroscopy and enabling new studies of molecular dynamics with efficient means of collecting dense information sets. We seek to gather practitioners and aspirants to share current work and ideas on new methods in spectroscopy.

11.8.6 Single Molecule Biophysics (with DBP and DPOLY)
This focus session will bring together experimentalists and theoreticians who use various single-molecule approaches to study the molecular mechanisms and discrete properties of RNA, DNA and proteins and polymers, in order to advance the knowledge on molecular and cellular biophysics. The focus session will cover a wide array of single-molecule techniques ranging from in vivo and in vitro fluorescence, atomic force microscopy and optical and magnetic tweezers, as well as theoretical approaches to analyze single-molecule data. This focus session will be useful to all who are interested in observing, manipulating, and elucidating the molecular mechanisms and discrete properties of biopolymers.

11.8.7 Production and Applications of Cold and Ultracold Molecules
There is great interest in the production of cold molecules, at temperatures below 1 K, and ultracold molecules, at temperatures below 1 mK. Such molecules have potential applications in areas ranging from precision measurement to quantum information storage and processing, and quantum gases of ultracold polar molecules are expected to exhibit novel quantum phases. In addition, cold molecules open up a new domain for collision physics, dominated by long-range forces and scattering resonances. There have been major recent advances both in cooling molecules from room temperature and in forming molecules in ultracold atomic gases. This focus session will explore both experimental and theoretical aspects of the new capabilities.

11.8.8 Electronic Transport in One-dimensional (1D) Nanomaterials
One-dimensional (1D) nanomaterials, including but not limited to nanowires, nanobelts and nanotubes, represent an important and broad class of nanomaterials at the forefront of nanoscience and nanotechnology. 1D nanomaterials can be rationally and predictably synthesized in single crystal form with all key parameters controlled during growth: chemical composition, diameter, length, doping, growth direction, possibly surfaces, spatial distribution and patterning, and choice of substrates. 1D nanomaterials thus represent one of best-defined and controlled classes of nanoscale building blocks, which correspondingly have enabled a wide-range of devices and integration strategies to be pursued in a rational manner. This focused session is about the forefront research in electronic transport in 1D nanomaterials related to their applications in nanoelectronics, nano-optoelectronics, nanophotonics, biomedical sciences, sensors, nano-enabled energy technology, nanopiezotronics, and environmental sciences.
