Angular dependence of sputtering yield of amorphous and polycrystalline materials
(2008)
An analytical formula is developed for the evolution of angular dependence of sputtering yields by extending the theory of sputtering yield proposed by Sigmund. We demonstrate that the peak of sputtering yield at oblique ...
Large volume, high-performance applications of fibers in civil engineering
(Wiley Periodicals, Inc., 2002-01-18)
This article presents an overview of fiber applications in cementitious composites. The socio-economic considerations surrounding materials development in civil engineering in general, and fiber reinforced cementitious ...
Completely discontinuous organic/ inorganic hybrid nanocomposites by self-curing of nanobuilding blocks constructed from reactions of [HMe 2 SiOSiO 1.5 ] 8 with vinylcyclohexene
(John Wiley & Sons, Ltd., 2007-11)
The reaction of 4-vinyl-1-cylcohexene with [HMe 2 SiOSiO 1.5 ] 8 provides tetra- and octa-2-cyclohexenylethyloctasilsesquioxanes. The tetrabifunctional [cyclohexenylethylMe 2 SiOSiO 1.5 ] 4 -[HMe 2 SiOSiO 1.5 ] 4 (average ...
Adsorption of catechol and comparative solutes on hydroxyapatite
(Wiley Subscription Services, Inc., A Wiley Company, 2003-08-15)
Contemporary medical and dental adhesives often have difficulty sticking to wet surfaces or weaken with long-term exposure to water. Substantial research has been dedicated to finding a means of achieving adhesion in an ...
Pattern formation in a polymer thin film induced by an in-plane electric field
(The American Institute of Physics, 2004-08-16)
This letter reports experimental work involving use of an in-plane electric field to induce morphological patterns in a thin polymer film. The film was first spin coated onto a glass wafer. Then, it was heated to above its ...
In vitro Toxicity Testing of Nanoparticles in 3D Cell Culture
(WILEY-VCH Verlag, 2009-05-18)
Common 2D cell cultures do not adequately represent the functions of 3D tissues that have extensive cell–cell and cell–matrix interactions, as well as markedly different diffusion/transport conditions. Hence, testing ...
Switchable Helical Structures Formed by the Hierarchical Self-Assembly of Laterally Tethered Nanorods
(WILEY-VCH Verlag, 2009-09-18)
The formation of helical scrolls formed by self-assembly of tethered nanorod amphiphiles and their molecular analogs are investigated. A model bilayer sheet assembled by laterally tethered nanorods is simulated and shown ...
Surface modification of neural recording electrodes with conducting polymer/biomolecule blends
(John Wiley & Sons, Inc., 2001-08)
The interface between micromachined neural microelectrodes and neural tissue plays an important role in chronic in vivo recording. Electrochemical polymerization was used to optimize the surface of the metal electrode ...
Focused ion beam modification of surfaces for directed self-assembly of InAs/GaAs(001) quantum dots
(IOP Publishing Ltd, 2007-11-14)
Controlled nucleation of InAs quantum dots has been achieved by Ga+ focused ion beam modification of GaAs(100) surfaces. Quantum dots may be induced in irradiated regions despite the fact that the deposited thickness is ...
