Effect of Li3+ Ion Irradiation on Ionic Transport Properties of Complexed Polymer Electrolytes
Authors: Gupta Prem Narain , Prajapati Govind Kumar , Roshan Rupesh 
Published: August 2010

AbstractSwift heavy ion (SHI) irradiation effects on ionic conduction in the PVA-H3PO4 polymer electrolyte films have been investigated due to its variety of applications in electrochemical devices. Polymer electrolytes films are irradiated with 50 MeV Li3+ ions having five different fluences viz. 5x1010, 1011, 5x1011, 1012 and 5x1012 ions/cm2. It is observed that irradiation of the polymer electrolyte films with swift heavy ions shows enhancement in conductivity at lower fluences and decrease in conductivity at higher fluences. It appears that below the critical fluence, swift heavy ion irradiation increases the diffusivity of Li+ ion in the polymer electrolyte which provides larger pathways for ionic transport throughout the system. The temperature dependence of electrical conductivity variation has been used to compute the activation energy involved in conduction process.
Proton Transfer in Perfluorosulfonic Acid Functionalized Carbon Nanotubes
Authors: Habenicht Bradley F , Paddison Stephen J , Tuckerman Mark 
Published: August 2010

AbstractProton dissociation and transfer are investigated with ab initio molecular dynamics (AIMD) simulations of carbon nanotubes (CNT) functionalized with perfluorosulfonic acid (-CF2SO3H) groups with 3 H2O/–SO3H. The CNT systems were constructed both with and without fluorine atoms covalently bound to the inner walls to determine the effects of the presence of fluorine on proton dissociation, hydration, and stabilization. The results of the AIMD trajectories show that decreasing the separation of sulfonic acid groups increases the propensity for proton dissociation. The simulations also revealed that the dissociated proton was preferentially stabilized as a hydrated hydronium (H3O+) cation in the CNT systems with the fluorine. This feature is attributed to the fluorine atoms providing a localized negative charge that promotes hydrogen bonding of the water molecules coordinated to the central hydronium ion. The hydrated H3O+ ion differed from a traditional Eigen cation (H9O4+) as it donated hydrogen bonds to sulfonate oxygen atoms, as well as water molecules.

Published: August 2010

AbstractState-of-the-art tissue engineering strategies increasingly rely on the performance of bioactive hydrogels formed via cell-friendly crosslinking reactions. Enzymatic reactions possess ideal characteristics for such applications, but they are currently still underexplored in biomaterials design. Here we report the development of hybrid bioactive hydrogels formed via a posttranslational modification reaction using phosphopantetheinyl transferase (PPTase). PPTase was shown to catalyze the covalent crosslinking of CoenzymeA-functionalized poly(ethylene glycol) (PEG) multiarm macromers and recombinantly produced acyl carrier protein (ACP) dimers. Crosslinking kinetics and physicochemical properties of PPTase hydrogels were characterized. Proof-of-principle experiments demonstrate the successful covalent bio-functionalization of gels with a CoA-derivatized cell adhesion peptide. Polymerization of gels in the presence of primary mammalian cells was shown to result in no loss in cell viability compared to a well established, chemically crosslinked gel system.
Concentrated crystallization of closely packed colloidal crystal films from aqueous suspension immersed in silicone oil
Authors: Fudouzi Hiroshi , Sawada Tsutomu , Brush Lucien 
Published: August 2010

AbstractColloidal crystals have been attracting much attention due to their novel use as 3D-photonic crystals and to their structural color. We have been developing a method for the colloidal crystal growth of opal films immersed in silicone oil. This method is one of the evaporative self-assembly techniques for opal films from colloidal particle suspensions. Understanding the mechanism of the process is important to assure the coating of high-quality opal thin films. The colloidal crystallization from suspension was observed with a long working distance optical microscope and Bragg's diffraction peaks were measured with a miniature fiber optic spectrometer. The transition from a non-crystalline to a crystalline phase is observed within a region between the disordered colloidal suspension and the colloidal crystal film. Within this region, that spans a distance of about 400μm, the lattice of the colloidal crystal reduces until it transitions to the close-packed structure.

Published: August 2010

AbstractA monolithic functional light guide is characterized with seven horizontal recessed V‐grooves on the back surface in order to realize a block‐wised scanning backlight for field‐sequential color LCD. Each V‐groove functions as semi partition between the consecutive blocks and its height controls the crosstalk between the blocks. To reduce the dispersion and enhance the luminance, the light guide is characterized with micro prism arrays on the light injection surface, the back surface, and front surface. Finally the monolith is combined with a single TIR prism film to direct the enhanced light toward the surface normal on each block.

Published: August 2010

AbstractA delta‐Sigma analog‐to‐digital (A/D) converter designed and implemented with the thin‐film transistors (TFTs) on glass substrate is proposed, which has been successfully verified in a 3‐μm low‐temperature polycrystalline silicon (LTPS) process. The experimental results have shown that the probability in the bit stream of the digital output from the delta‐Sigma modulator is correctly fit in the analog input voltage ratio. Such a bit stream can be converted into 8‐bit digital code successfully under the operation voltage of 10V with thin‐film transistors (TFTs) on the glass substrate. The proposed delta‐Sigma A/D converter can be further used to achieve the precise analog circuits for System‐on‐Panel (SOP) or System‐on‐Glass (SOG) applications, which enables the analog circuits to be integrated in the active matrix LCD (AMLCD) panels.

Published: August 2010

AbstractAccurate colorimetric characterization is an important step in establishing the color management system (CMS) for liquid crystal displays (LCDs). The difficulty in achieving accurate characterization of LCDs is mainly due to cross talks among color channels. In this paper, a model based on the concept of under color removal (UCR) and utilizing the correlations among color components is proposed to accurately estimate the XYZ values of the colors displayed on LCDs. Experimental results indicate that the proposed model outperforms many existing models in terms of the CIEDE2000 color difference between the XYZ values of the measured color samples and the estimated XYZ values.

AbstractThe polymer‐stabilized blue phase liquid crystals are in the limelight of liquid crystal display area because of its fast response and wide viewing angle with alignment layer free. The conventional device is driven by in‐plane field, which has thin electrodes only on bottom substrate and also due to low Kerr constant of LC, the driving voltage of the device is very high. We propose improved electrode structure which has partition‐wall shaped electrodes. The proposed device has maximized horizontal electric field so that the driving voltage is decreased. Further, adoption of two transistors can lower driving voltage.

Published: August 2010

AbstractMorphological and molecular orientational anisotropies of a rubbed polyimide film, which is a general alignment layer in a mass production of the 42″ IPS‐mode LCD, were analyzed. The results of our AFM (Atomic Force Microscopy) and XRR (X‐ray Reflectivity) measurements of rubbed polyimide surface didn't show any morphological anisotropy between parallel and perpendicular to a rubbing direction. On the other hand, orientational anisotropy of polyimide chains on their surface was observed by a NEXAFS (Near Edge X‐ray Adsorption Fine Structure) analysis. The reason for this is that the hardness of a polyimide film and the rubbing process in LCD manufacturing were optimized to minimize a rubbing scratch, which deteriorates an image quality if any. From these results, we imply that only molecular orientation without any morphological anisotropy at the polyimide surface is enough to attain LC (Liquid Crystal) alignment ability for currently mass‐produced IPS‐mode LCD products. In order to reveal the effect of molecular anisotropy on LC alignment properties, we enhanced the orientational anisotropy of polyimide chains by changing their molecular structures. We then confirmed that the increase of the orientational anisotropy could improve contrast ratio of a 42″ IPS‐mode LCD TV.
