PHYS Symposia at the Fall 2014 ACS National Meeting
in San Francisco, California

Program Chair: Prof. Nancy Levinger


The Physical Chemistry Division is pleased to sponsor the following symposia at the upcoming ACS National Meeting, August 10-14, in San Francisco. The complete symposium schedules will soon be available on the ACS website.

THE FUTURE OF COMPUTATIONAL CHEMISTRY

The future of computational chemistry hinges not only on the accuracy of its underlying models but also on the efficiency and efficacy of its algorithms and software. In all areas of molecular-level simulation, including not only traditional chemistry but materials and biomolecular science as well, recent theoretical advances have yielded unprecedented levels of accuracy and understanding for a broad array of fundamental chemical phenomena. However, the concomitant development of new, high- performance computing architectures - from now-common petascale computers to highly anticipated exascale systems—presents innumerable challenges for those implementing new methods in production-level software. This symposium will bring together experts in quantum chemistry, biomolecular simulation, and condensed-matter physics to highlight the current state of the art in both methodology and software design, and to explore paths forward toward sustainable and extensible codes that can take full advantage of the ever-changing landscape of cyberinfrastructure.

PHYSICAL CHEMISTRY OF IONIC LIQUIDS

From fundamental studies to applications in energy, catalysis and separations, ionic liquids are permeating all aspects of modern chemistry. Physical chemistry plays a leading role in understanding chemical reactivity, relaxation phenomena, structure and interfacial behavior in these diverse materials. This symposium will present the latest advances in the physical chemistry of ionic liquids on a range of topics that include the relationships between ionic liquid structure and physical and transport properties, volatility and thermal stability, electron transfer, photolysis and radiolysis, ultrafast to ultra-slow spectroscopy, separations and solubility, interfaces with bulk and nanomaterials, and catalysis.

RENEWABLE ENERGY GENERATION AT THE INTERFACE BETWEEN THEORY AND EXPERIMENT

This symposium is designed to highlight the collaborative efforts of experimentalists and theoreticians in the area of renewable energy, spark cross-disciplinary discussions, and explore the relationship between computation and experiment more deeply. The topics for this symposium include the following: Artificial Photosynthesis, Proton-Coupled Electron Transport, Catalysis (water oxidation, carbon dioxide reduction, nitrogen reduction, and hydrogen generation), and Solar Cells (dye-sensitized solar cells, quantum dot solar cells, organic photovoltaics, and new cell architectures).

WHAT DOES 20TH CENTURY PHYSICAL CHEMISTRY HAVE TO SAY TO 21ST CENTURY PHYSICAL CHEMISTS?

The 20th century was the great age of physical chemistry. It started with the first Nobel Prize in Chemistry in 1901 to van't Hoff and continued right up to the close of the century with Zewail in 1999. Many paradigms were established for all time—not just for the 20th century. Indeed, for any field to be dynamic, it needs to both move forward and to remember its roots. Fortunately, there are many living physical chemists who are bringing the excitement of these foundational achievements to the current membership of PHYS. Thus, this symposium will feature many leaders of physical chemistry who are truly excited about revisiting the history of physical chemistry in dynamic ways.

EXTREME BIOCHEMISTRY FROM SMALL MOLECULES TO LARGE PROTEINS: FORMATION, STABILITY, STRUCTURE AND FUNCTION

The origin and adaptability of life on Earth holds a fascination for most of us and is a central and compelling field of study for many scientists. Chemists have been involved in this field in many ways, including discovering how simple biomolecules, as building blocks for life, can be generated under prebiotic conditions, and how biomolecular processes can be adapted to extreme environmental conditions. More broadly, a study of extremophile biochemistry should, in principle, provide guidelines for the formation and evolution of life elsewhere, assuming that evolution is a general principle underlying the development of living systems on other planets besides Earth. In this symposium, we will combine members of the astrochemistry community with biochemists and chemists working on the properties of extremophiles to provide a broad picture of the latest results and insights into how, under extreme conditions, simple molecules become more complex, as well as how complex biomolecules (proteins, nucleic acids, etc.) adapt to inhospitable environments to enable and extend life in surprising habitats. Topics include interstellar chemistry, prebiotic terrestrial chemistry, and the properties and structures of extremophile proteins from extreme thermal, chemical and other challenging environments. The utilization of these studies to biotech applications will also be presented.

FUNDAMENTAL PROCESSES OF ATMOSPHERIC CHEMISTRY

Although several decades of research have greatly advanced our understanding of the physical chemistry of the atmosphere, there remain many outstanding research areas that are poorly understood. These questions include the potential for organic oxidation to recycling radical species, the chemical mechanisms and kinetics behind the oxidation of organic and inorganic compounds, gas- particle partitioning of multi-generational oxidation products, and the potential for compounds in the atmosphere to affect the radiative balance of the planet through the formation of cloud and ice condensation nuclei, light scattering of aerosol particles, and absorption by brown and black carbon. Research approaches into these problems include ambient observations, laboratory experiments and theoretical studies. The development of new chemical detectors and in situ perturbation studies are leading to new measurements and new insights that are driving the development of models. Recent advances have led to better predictions of atmospheric chemistry and its effects on the atmosphere’s radiative properties.

MOLECULAR AND NANOSCOPIC PROBES FOR BIOLOGICAL SYSTEMS

Biological systems are highly heterogeneous and dynamic, and the study of this topic has a cross- disciplinary impact on physical chemistry, biophysics, molecular and cell biology, materials science, translational medicine and multiple engineering fields. Recent developments show the critical importance of using molecular or nanoscopic probes to study the structure, diversity and function of various biological entities in cells or tissues. This symposium will present new advances in this vibrant research area. In particular, it will bring together experimentalists, theoreticians, and computational scientists to forge a scientific culture of fluid exchange of ideas and collaboration across disciplines and among laboratories.

COMPUTATIONAL SPECTROSCOPY

Experiments in spectroscopy have laid the foundation for current understanding of, for example, the electronic and magnetic properties of molecules, reactive intermediates, combustion chemistry, materials, and surface and interfacial chemistry. This Computational Spectroscopy Symposium will highlight the significant impact that computational chemistry has made on the interpretation and prediction of spectroscopic measurements. Since many of the more recent important advances have been achieved through close collaborations between theorists and experimentalists, prominent and emerging scientists representing both theory and experiment will be invited to give talks in areas of electronic, vibrational, ultrafast, and magnetic resonance spectroscopies of both gas- and condensed phases.

PHOTOINDUCED PROTON TRANSFER IN CHEMISTRY AND BIOLOGY

Proton transfer is one of the most fundamental chemical reactions in nature. However, understanding the ways in which the environment mediates proton dynamics remains a fundamental challenge. Excited-state proton transfer (ESPT), as well as more general photoinduced proton transfer (PPT), continues to provide a rich vein of new research activity. The range of systems that has pushed the limits of theory has greatly expanded in the past decade. The topics cover modern PPT theory, syntheses of novel photoacids and photobases, and studies of their PPT in a wide array of systems from gas phase to proteins and DNA. Numerous PPT applications will be discussed, including the utilization of reversible and irreversible pH-jumps using transient photoacids and PAGs, and recent advances in the development optically-active, intramolecular ESPT-based materials. A broad spectrum of PPT-related problems will bring together the leading specialists—not only from the world of physical chemistry, but theoreticians, biochemists, organic and material chemists from all over the world.
