Nanoengineered Materials: From Polymer Composites to Structured Adsorbents
نویسندگان
چکیده
The challenge for nanoscale modeling and simulation is to bridge the length and time scales that are necessary to connect nanostructure of the material with its macroscopic properties. This challenge can only be met by combining the efforts of individual researchers who collectively are expert in a wide range of computational and theoretical techniques. The team we have assembled from the University of Pittsburgh (including senior collaborators, R. D. Coalson and K. D. Jordan, Department of Chemistry) and M.I.T. contains representation and perspectives from the traditional disciplines of physics, chemistry, chemical engineering and materials science. Our aim is to attack problems of critical importance to the energy and chemical industries, for example, the efficient design of nanocomposites, polymeric batteries, adsorbents for hydrogen storage and molecular sieves for gas separation.

متن کاملHierarchical Composites Made Entirely from Renewable Resources
Recent interest in the utilisation of greener materials has reinitiated the interest in natural fibres and/or fibrils as reinforcement for polymers. However, such bio-based composites often exhibit properties that fall short of expectations due to (i) inadequate processing conditions, resulting in filler agglomeration and poor filler dispersion within the matrix, (ii) variations in natural fibr...
متن کاملIonic liquids modified graphene oxide composites: a high efficient adsorbent for phthalates from aqueous solution
In 2015, more than 30% of erasers were found to contain a PAE content that exceeded the 0.1% limit established by the Quality and Technology Supervision Bureau of Jiangsu Province in China. Thus, strengthening the supervision and regulation of the PAE content in foods and supplies, in particular, remains necessary. Graphene oxide (GO) and its composites have drawn great interests as promising a...
متن کاملSynergistic Removal of Pb(II), Cd(II) and Humic Acid by Fe3O4@Mesoporous Silica-Graphene Oxide Composites
The synergistic adsorption of heavy metal ions and humic acid can be very challenging. This is largely because of their competitive adsorption onto most adsorbent materials. Hierarchically structured composites containing polyethylenimine-modified magnetic mesoporous silica and graphene oxide (MMSP-GO) were here prepared to address this. Magnetic mesoporous silica microspheres were synthesized ...
