This paper provides an empirical test of the hypothesis that the Japanese government has undertaken a successful strategic trade policy in the semiconductor industry. Quantifiable R & D and tariff policy as they relate to the semiconductor industry and their impact on firms in the US "merchant" semiconductor market are considered. The test results do not support the hypothesis as it applies to government R & D expenditures and tariffs. These Japanese government policies have not had a significant adverse impact on the profits of three important US semiconductor producing firms.
Multilayered Polymer-Coated Carbon Nanotubes To Deliver Dasatinib
Moore, Thomas L.,Grimes, Stuart W.,Lewis, Robert L.,Alexis, Frank American Chemical Society 2014 MOLECULAR PHARMACEUTICS Vol.11 No.1
<P>Multilayered, multifunctional polymer coatings were grafted onto carbon nanotubes (CNTs) using a one-pot, ring-opening polymerization in order to control the release kinetic and therapeutic efficacy of dasatinib. Biocompatible, biodegradable multilayered coatings composed of poly(glycolide) (PGA) and poly(lactide) (PLA) were polymerized directly onto hydroxyl-functionalized CNT surfaces. Sequential addition of monomers into the reaction vessel enabled multilayered coatings of PLA-PGA or PGA-PLA. Poly(ethylene glycol) capped the polymer chain ends, resulting in a multifunctional amphiphilic coating. Multilayer polymer coatings on CNTs enabled control of the anticancer drug dasatinib’s release kinetics and enhanced the in vitro therapeutic efficacy against U-87 glioblastoma compared to monolayer polymer coatings.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/mpohbp/2014/mpohbp.2014.11.issue-1/mp400448w/production/images/medium/mp-2013-00448w_0009.gif'></P>
Proximity field nanopatterning of azopolymer thin films
Lambeth, Robert H,Park, Junyong,Liao, Hongwei,Shir, Daniel J,Jeon, Seokwoo,Rogers, John A,Moore, Jeffrey S IOP Pub 2010 Nanotechnology Vol.21 No.16
<P>A method for inscribing surface relief gratings in azopolymer thin films via proximity field nanopatterning is reported. Azopolymers prepared by ring opening metathesis polymerization were cast as thin films and brought into conformal contact with transparent polydimethylsiloxane phase masks. Irradiation of the film surface through the phase masks induces mass transport of azopolymer that generates surface relief structures on the basis of the intensity modulation of the light by structures on the phase mask. The experimental images obtained matched well with those produced by optical simulation. A wide variety of structures could be inscribed in the film surface which depended on the molecular weight of the azopolymer and irradiation time. Control experiments conducted suggest that the process is entirely photonic and that the presence of the phase mask on the film surface did not affect the inscription process. </P>
Linear coupling of alignment with transport in a polymer electrolyte membrane
Li, Jing,Park, Jong Keun,Moore, Robert B.,Madsen, Louis A. Nature Publishing Group 2011 NATURE MATERIALS Vol.10 No.7
Polymer electrolyte membranes (PEMs) selectively transport ions and polar molecules in a robust yet formable solid support. Tailored PEMs allow for devices such as solid-state batteries,??artificial muscle?? actuators and reverse-osmosis water purifiers. Understanding how PEM structure and morphology relate to mobile species transport presents a challenge for designing next-generation materials. Material length scales from subnanometre to 1??關m (refs?, ) influence bulk properties such as ion conductivity and water transport. Here we employ multi-axis pulsed-field-gradient NMR (ref.?) to measure diffusion anisotropy, and <SUP>2</SUP>H NMR spectroscopy and synchrotron small-angle X-ray scattering to probe orientational order as a function of water content and of membrane stretching. Strikingly, transport anisotropy linearly depends on the degree of alignment, signifying that membrane stretching affects neither the nanometre-scale channel dimensions nor the defect structure,causing only domain reorientation. The observed reorientation of anisotropic domains without perturbation of the inherent nematic-like domain character parallels the behaviour of nematic elastomers, promises tailored membrane conduction and potentially allows understanding of tunable shape-memory effects in PEM materials. This quantitative understanding will drive PEM design efforts towardsoptimal membrane transport, thus enabling more efficient polymeric batteries, fuel cells, mechanical actuators and water purification.
