Efficient CO2 Sorbents Based on Silica Foam with Ultra-large Mesopores
(Energy & Environmental Science, 2012-04-19)A series of high-capacity, amine impregnated sorbents based on a cost-effective silica foam with ultra-large mesopores is reported. The sorbents exhibit fast CO2 capture kinetics, high adsorption capacity (of up to 5.8 ... -
Effects of Bonding Types and Functional Groups on CO2 Capture using Novel Multiphase Systems of Liquid-like Nanoparticle Organic Hybrid Materials
(Environmental Science & Technology, 2011-06-15)Novel liquid-like nanoparticle organic hybrid materials (NOHMs) which possess unique features including negligible vapor pressure and a high degree of tunability were synthesized and their physical and chemical properties ... -
Dynamics of Solvent-free Grafted Nanoparticles
(The Journal of Chemical Physics, 2012-01-26)The diffusivity and structural relaxation characteristics of oligomer-grafted nanoparticles have been investigated with simulations of a previously proposed coarse-grained model at atmospheric pressure. Solvent-free, ... -
Dynamics in Coarse-grained Models for Oligomer-grafted Silica Nanoparticles
(The Journal of Chemical Physics, 2012-05-30)Coarse-grained models of poly(ethylene oxide) oligomer-grafted nanoparticles are established by matching their structural distribution functions to atomistic simulation data. Coarse-grained force fields for bulk oligomer ... -
Diffusivities, viscosities, and conductivities of solvent-free ionically grafted nanoparticles
(Soft Matter, 2013-05-28)A new class of conductive composite materials, solvent-free ionically grafted nanoparticles, were modeled by coarse-grained molecular dynamics methods. The grafted oligomeric counterions were observed to migrate between ... -
Diffusive Dynamics of Nanoparticles in Aqueous Dispersions
(Soft Matter, 2012-10-04)The diffusive dynamics of 100 nm to 400 nm diameter polystyrene nanoparticles dispersed in water were studied using brightfield and fluorescence based differential dynamic microscopy (DDM) and compared to those obtained ... -
Deposition of LDH on Plasm Treateed Polylactic Acid to Reduce Water Permeability
(Journal of Colloid and Interfcae Science, 2013-04-04)A simple and scalable deposition process was developed to prepare polylactic acid (PLA) coatings with enhanced water barrier properties for food packaging applications. This method based on electrostatic interactions between ... -
Crowded, Confined, and Frustrated: Dynamics of Molecules Tethered to Nanoparticles
(Physical Review Letters, 2012-12-19)Above a critical chemistry-dependent molecular weight, all polymer molecules entangle and, as a result, exhibit slow dynamics, enhanced viscosity, and elasticity. Herein we report on the dynamics of low molecular weight ... -
Chloride Adsorption by Calcined Layered Double Hydroxides in Hardened Portland Cement Paste
(Materials Chemistry and PHysics, 2014-02-13)This study investigated the feasibility of using calcined layered double hydroxides (CLDHs) to prevent chloride-induced deterioration in reinforced concrete. CLDHs not only adsorbed chloride ions in aqueous solution with ... -
