New Strategies for the Synthesis of Mesoporous Materials, at the ACS National Meeting, April 2008, New Orleans, LA
ACS Nanostructured Materials Symposium 2008 Spring Organizer: Peidong Yang, University of California, Berkeley Xiaogang Peng, University of Arkansas Chris Murray, University of Pennsylvania Nanostructured material has been a very exciting research topic in the past two decades. The impact of these researches to both fundamental science and potential industrial application has been tremendous and is still growing. There are many exciting examples of nanostructured materials in the past decades including colloidal nanocrystal, bucky ball C60, carbon nanotube, semiconductor nanowire, nanocomposite and porous material. The field is quickly evolving and is now intricately interfacing with many different scientific disciplines, from chemistry to physics, to materials science, engineering and to biology. The research on nanostructured materials has been highly interdisciplinary because of different synthetic methodologies involved, as well as many different physical characterization techniques used. This symposium aims at providing opportunities for intensive discussions and exchange of ideas by bringing together experts working on the synthesis of nanofunctional materials, nanostructural fabrication, novel physical and chemical property characterization as well as nanoscale device fabrication and testing. The technical focus of this symposium is fundamental and directly related to petroleum field. The synthesis and characterizations of nanocrystals, nanowires, nanotubes, porous materials and organic nanostructures are highly relevant to the topics of PRF interest: a. Materials Science: Materials for efficient generation, storage or conversion of energy; b. Polymer Science, Synthesis, characterization, and properties of polymers and dendrimers; c. Surface Science , Surface science, heterogeneous catalysis, thin films, porous materials. A direct example of the nanostructures’ relevance to the petroleum field is the area of solar to fuel conversion. The design, synthesis, and characterization of inorganic, organic and composite nanostructures are all critical to the ultimate accomplishment of high efficiency solar to fuel conversion. The generation of solar fuels by the direct conversion of light energy to fuel molecules in a single device is an attractive goal, but no such system has been demonstrated that shows the required efficiency, is sufficiently durable, or can be manufactured at reasonable cost. The direct solar to fuel approach is inspired by nature’s photosynthetic organisms that accomplish the conversion of carbon dioxide and water to carbohydrates in a single integrated system. The photosynthetic machinery of plants, algae or bacteria displays the crucial design features for an engineered solar to fuel conversion system: vectorial arrangement of molecular components that accomplish light absorption, charge separation and transport, and the conversion of the stored potential to high energy chemicals and oxygen at catalytic sites in compartmentalized spaces. To develop efficient and durable engineered systems for solar to fuel conversion that take advantage of concepts and structures used by nature at the component and integration level, the rational design, synthesis and integration of the inorganic/organic/hybrid nanostructures at multiple length scales will play the critical role. This proposed symposium will highlight the recent advance in these important research directions. With the partial support from ACS-PRF, we were able to put together a very successful symposium with many high profile speakers both inside and outside of the States. The symposium has been very well attended during the meeting, with typical audience of over 100 every day (from Sunday to Thursday).
