Tailoring the Permselectivity of Water Desalination Membranes via Nanoparticle Assembly

January 6, 2014
Author(s)
Edwin Chan, William Mulhearn, Jung-Hyun Lee, Daeyeon Lee, Christopher Stafford
: Thin film composite membranes can selectively separate mono- and di-valent ions from water via solution-diffusion of each species through a dense but ultrathin, highly crosslinked polymer ‘skin' layer - water is transported across the membrane faster

Viscosity Modifiers to Enhance Concrete Performance

May 6, 2013
Author(s)
Dale P. Bentz
The hazard rate function for concrete structures often is portrayed as a “bathtub”-shaped curve, with a finite ever-decreasing probability of early-age failures being followed by a life with a relative low, constant probability of failure that ultimately

Copper oxide nanoparticle mediated DNA damage in terrestrial plant models

December 22, 2011
Author(s)
Bryant C. Nelson, Donald H. Atha, Elijah J. Petersen, Huanhua Wang, Danielle Cleveland, Richard D. Holbrook, Pawel Jaruga, M Miral Dizdar, Baoshan Xing
Engineered nanoparticles, due to their unique electrical, mechanical and catalytic properties, are presently found in many commercial products and will be intentionally or inadvertently released at increasing concentrations into the natural environment

Diffusivity and Mobility Data

December 31, 2009
Author(s)
Carelyn E. Campbell
Diffusion is the process by which molecules, atoms, ions, point defects, or other particle types migrate from a region of higher concentration to one of lower concentration. The diffusivity of an atom or diffusion coefficient is the rate at which a

Near-Critical Behavior of Aqueous Systems

October 16, 2008
Author(s)
M A. Anisimov, Jan V. Sengers, Johanna Levelt Sengers
This chapter concentrates on the thermophysical properties of water, steam and aqueous solutions in a large range around the water critical point. The chapter is written for a technically knowledgeable audience without specialized background in fluid

Liposome-Templated Supramolecular Assembly of Responsive Alginate Nanogels

March 14, 2008
Author(s)
Jennifer S. Hong, Wyatt N. Vreeland, Silvia H. De Paoli Lacerda, Laurie E. Locascio, Michael Gaitan, Srinivasa R. Raghavan
Nanosized gel particles (nanogels) are of interest for a variety of applications, including controlled release of drugs and single-molecule encapsulation. Here, we employ the cores of nanoscale liposomes as reaction vessels to template the assembly of

MALDI-TOF MS Characterization of Covalent Cationized Polyethylene

August 1, 2003
Author(s)
Sheng Lin-Gibson, D L. Brunner, David L. VanderHart, Barry J. Bauer, B M. Fanconi, Kathleen M. Flynn, William E. Wallace
… salts with matrix. One approach to increase the polymer ion signal is to apply more aggressive laser power; however, …
