Engineering Research Equipment Grant: Fourier Transforms Infrared Spectrometer-Characterization and Applications of Polymer and Silane Modified Oxied Surface @ University of California-Los Angeles
This equipment proposal is for the purchase of a Fourier Transform Infrared/Internal Reflection Spectrometer (FTIR/IRS) for the study of chemically modified oxide surfaces (eg silica) and their applications. The modified surfaces will consist of a solid substrate modified by surface-graft polymerization or surface silylation. The proposed study of surface-grafting polymerization and silylation will consist of in situ studies of the kinetics and efficiency of surface activation and surface polymerization. This information will be used to support ongoing work on the synthesis of novel polymer-solid matrix resins for aqueous exclusion chromatography, adhesion enhancement in polymer composites, and rheology of interacting colloids as occur in the manufacture high performance ceramics.

Selective Ceramic-Supprted Polymer Membranes @ University of California-Los Angeles
The Main objective of this project is the preparation and development of inorganic-polymeric membranes for separation processes. These composites should combine the structural strength of inorganic membranes with the high selectivity of the polymeric varieties. Fabrication will start with a vinyl silanation of an inorganic membrane substrate followed by free radical graft polymerization onto these vinyl moiety surface sites. Properties of the final composite can be altered through the structure of the inorganic support (e.g. pore size), the density of graft sites, choice of monomeric species, and the reaction conditions for the polymerization. Membranes will be tested for hydraulic permeability and for basic separation performance. Certain membrane processes are well-suited to separations involving dilute solutions like the purification and concentration of biomolecules or the removal of heavy metals from wastewater streams. Others like pervaporation of volatile organic mixtures have the potential to replace distillation as the method of separation. Materials development is essential if the expected potential of membrane separation methods to address important environmental and industrial problems is to be realized and if the United States is to continue as a leader in the production and sales of membranes worldwide. The ceramic-supported polymeric hybrid membranes contribute to this effort.

Polymer-Ceramic Pervaporation Membranes For Organic-Organic Liquid Separation (Tse99-D) @ University of California-Los Angeles
ABSTRACT CTS-9985532 Y. Cohen, University of California, Los Angeles
There is a growing need in chemical manufacturing and pollution prevention for new processes capable of selectively separating and concentrating target species from organic liquid mixtures to increase product purity and for in-process recycling. In recent years, membrane systems have been touted as an efficient means to achieve difficult liquid-phase separations, especially from dilute solutions, at a reduced energy consumption level relative to conventional technologies (e. g., distillation, extraction). Despite the attractiveness of membrane technology, selective membrane technology, selective membranes for organic-organic liquid separations with adequate structural integrity and longevity are lacking. In order to meet the above challenge, the proposed project will focus on the development and demonstration of novel class of robust hybrid polymer, ceramic (PolyCer) membranes for organic-organic separations. The proposed PolyCer membranes will be fabricated by a surface-graft polymerization process resulting in a molecular layer of polymer chains which are terminally and covalently anchored to the pore surface of the porous ceramic support. Given the covalent anchoring of the active polymer chains, the PolyCer membrane will retain its structural integrity and performance even when the polymer phase is exposed to organics that are good solvents for the polymer. Through the selection of the polymer most appropriate for the desired separation task, the polymer surface layer can be synthesized to impact specific separation properties to the membrane. It is expected that this project will lead to the demonstration of a new technology for the tailor design of a new class of selective and robust ceramic-supported polymer membranes. The new approach will allow the rapid deployment of task-specific membranes for in-processes separation for recovery and recycle a selective replacement of energy intensive separation processes (e.g., distillation) in a variety of industrial applications.

Cein: Predictive Toxicology Assessment and Safe Implementation of Nanotechnology in the Environment @ University of California-Los Angeles
University of California-Los Angeles Columbia University University of Bremen University of British Columbia University of California-Davis University of California-Riverside University of California-Santa Barbara University of Texas-El Paso
This award establishes a Center to conduct research and education on the interactions of nanomaterials with living systems and with the abiotic environment. The goals of this Center are to develop a predictive understanding of biological and ecological toxicology for nanomaterials, and of their transport and transformation in the environment. This Center engages a highly interdisciplinary, multi-institutional team in an integrated research program to determine how the physical and chemical properties of nanomaterials determine their environmental impacts from the cellular scale to that of entire ecosystems. The research approach promises to be transformative to the science of ecotoxicology by combining high throughput screening assays with computational and physiological modeling to predict impacts at higher levels of biological organization. The Center will unite the fields of engineering, chemistry, physics, materials science, cell biology, ecology, toxicology, computer modeling, and risk assessment to establish the foundations of a new scientific discipline: environmental nanotoxicology.
Research on nanomaterials and development of nanotechnology is expanding rapidly and producing discoveries that promise to benefit the nation?s economy, and improve our ability to live sustainably on earth. There is now a critical need to reduce uncertainty about the possible negative consequences of nanomaterials in the environment, while at the same time providing guidelines for their safe design to prevent environmental and toxicological hazards. This Center addresses this societal need by developing a scientific framework of risk prediction that is paradigm-shifting in its potential to keep pace with the commercial expansion of nanotechnology. Another impact of the Center will be development of human resources for the academic community, industry and government by training the next generation of nano-scale scientists, engineers, and regulators to anticipate and mitigate potential future environmental hazards of nanotechnology. Partnerships with other centers will act as powerful portals for the dissemination and integration of research findings to the scientific, educational, and industrial communities, both nationally and internationally. This Center will contribute to a network of nanotechnology centers that serve the national needs and expand representation and access to this research and knowledge network through an internship program directed at California community colleges serving underrepresented groups. Outreach activities, including a journalist?scientist communication program, will serve to inform both experts and the public at large about the safety issues surrounding nanotechnology and how to safely produce, use, and dispose of nanomaterials.
