Microporous Liquids for Aqueous-Phase Gas Absorption
Abstract
The proposed research targets a revolutionary class of materials?aqueous fluids with permanent microporosity?that possess both intri,nsic porosity and fluidity, affording liquids with extremely high gas absorption capacities. By dispersing microporous nanoparticles, with specially selected internal surface chemistries in aqueous media, thermodynamically stable micropores in excess of 10 vol % ca,n be introduced to water without compromising the fluidity of the overall solution. Already, candidate microporous fluids developed,in our lab have demonstrated gas capacities greatly exceeding even that of a pure gas phase, while possessing low viscosities. Furth,ermore, these solutions display extremely rapid gas exchange kinetics and excellent reversibility, as well as stabilities for up to,6 months. By investigating and optimizing the biological stability, performance, and compatibility of these materials, we seek to cr,eate a unique approach to designing porous aqueous fluids for in vitro and in vivo uses, including decompression sickness treatment,by facilitating N2 removal prior to bubble formation. Top-performing materials are expected to open new areas of research within bio,logical gas absorption and storage and provide insights relevant to use in biological systems. This research will contribute to new,applications of particular importance to the ONR and DoD, including the treatment of decompression sickness in deep sea diving, toxi,c gas removal, and high-density gas storage. This research effort will be led by Professor Jarad A. Mason in the Department of Chemi,stry and Chemical Biology at Harvard University, and Dr. Yifeng Peng in the Harvard Medical School and the Department of Cardiology,at Boston Children?s Hospital will serve as a co-PI. The proposal title is: ?Microporous Liquids for Aqueous-Phase Gas Absorption?.,The total funds requested from ONR for the performance period is $200,000.THIS ABSTRACT IS PUBLICLY RELEASABLE.
